How can we easily open and close ports on the Windows 10 firewall

Using a firewall on Windows is advisable to enhance our security. Sometimes it could be useful to open certain ports to accelerate the download speed. Also, it can be useful for some video games, for example. Just so we can understand, ports on Windows are something like a door for data packages. Because of this, if we open a specific port, more packages can enter and exit. In this article we will explain how to open or close ports on Windows 10 firewall.

Opening or closing ports on Windows firewall

The first thing we need to do, logically, is access the firewall. To get there we need to go to the Control Panel. Here we select System and Security and after that Windows Firewall.

Windows 10 firewall lets us create rules. These are the options we can set to open or close specific ports. The instructions we give to our system. Creating a new rule is very simple, you just have to follow these instructions:

  • Click on Advanced Settings
  • A pop-up window appears and we select Inbound Rules on the left and click on Create new rule on the right

The rule-creation assistant for Windows firewall opens up. What we want is to create something that allows us to open or close ports. In order to do this, we need to add the different values:

  • Choose port
  • TCP Protocol
  • Specific local ports: the port we want to open or close, depending on the case
  • ¿When to apply this rule? We mark the three options

We should choose a name in order to recognize it easily. This allows us to easily modify this in the future.

This way, we can open or close ports on Windows 10. As we said, there may be situations in which we need to do this. It could be to play a videogame, use a download program or any other situation.

Both opening and closing ports with the Windows 10 firewall is very easy.

The firewall’s importance

In a previous article we talked about the firewall, what is it and how can it help us enhance our device’s security. It is something that, together with a good antivirus and other tools and security programs, can strengthen our system. This way, we can face possible threats that put the functioning of our device at risk.

As we know, a firewall can be a software, that is, a program we can install in our device. This is the case of the firewall that comes with Windows 10. Or it can also be a hardware, that is, a device that is connected between the network and the computer. It can also be a program installed on the router that acts as a firewall.

In all of this situations it has the same function. It is a wall between the network and our devices. This way we can define what we want to enter them and what we don’t.

Edit any PDF document uploaded to Google Drive from Android

Editing PDF documents in good conditions and in a professional way is one of the hardest activities to do, even in computers. The PDF format was created by Adobe and, even though there are a lot of tools to open and visualize them, in terms of editing them, things get messy, unless we use professional applications such as Adobe Acrobat, which is paid. However, little by little mobile devices are substituting computers, up to the point that it is possible to edit PDF documents with a professional touch even from the cloud and using free applications.

As it couldn’t be any other way, on the network there are many free alternatives to edit PDF on a computer, for every kind of operative system, still, these usually don’t give professional results nor are as precise as Adobe itself, or other similar professional tools, besides lacking some features.

Owing to the power of modern smartphones and tablets, and to systems like Android, today it is also possible to use our smartphone for editing this dype of document. Furthermore, currently there exist a great variety of tools, even free ones, that allow us to edit them with great precision, even if we have them uploaded on the cloud, for example, in Google Drive.

If we work frequently with PDF files, in the next guide we explain to you how we can edit any PDF document submitted to Google Drive from our Android smartphone.

Our Android as a complete office suite

Today we can find a great variety of office applications for our mobile operating system. Beyond Google Drive, and the whole Google Docs tools suite, which are ideal for working with documents on the cloud, also we can find different office suites that allow us as much to create PDF documents as to edit them.

Without going any farther, if we are used to working with Microsoft Office on a computer, we will be able to download from the Play Store the applications Word, Excel, etc, that allow us to work from Microsofts office suite. Also we will find many other alternatives, like the LibreOffice display (developing an editor), or slightly lesser known suites, like that of WPS and OfficeSuite, which also harbor great potential and which allows us to change our phones into complete multimedia suites for visualising, creating and practically editing any time of document.

 

 

Mozilla already has the first beta to Firefox 40 with great improvements for Linux users

Mozilla has launched the first beta version of the popular web browser Firefox 40, this new version promises higher performance, but the most remarkable thing about this version is in the users of operating systems based on Linux that use Firefox. Mozilla has made big efforts to optimize it to the maximum and give the best possible performance.

The three most important improvements that Linux users will find is when they do “scroll” in website, now it is going to be much fluid than before, besides Mozilla has also improved the videos and graphics reproduction.

Even though the Firefox 39 version was launched a few days ago with a big ammount of internal changes and bug fixes, they hadn’t incorporate enough important changes, however, with Firefox 40 these changes do came, especially to Linux users where they focused a great part of the developers efforts.

We recommend you read our article with all the news of this Firefox 39 version:

Most of the changes are applied in every Firefox version on the different platforms (Windows, Linux, Mac OS X and Android). However, some of them are only available on one OS or another. For example, in the latest Firefox version 39 changes were applied that only affected Mac OS X. Now, the developers have been working on enhancing the Linux version and this is good news because it shows that they haven’t forgotten about this operative system.

If you are a Linux user you’ve probably noticed that Google Chrome loads quite faster than Firefox and that navigation is a bit more fluent. Now, developers have upgraded this speed so even though it is not as fast as Chrome, you will definitely notice the difference, which means developers are on the right path.

Other important changes that developers have been planning for the next versions are to protect us from malicious software, for example, letting us know about add-ons that are not digitally signed by Mozilla. Also, they will put special attention on JPG images so they consume less storage resources.

We recommend you to access Softpedia where you will find a link to download Firefox 40 beta for Linux for trial.

How to delete videos and photos from WhatsApp to free up space on the phone

WhatsApp is the most used messaging tool in the whole world and it is likely that most of your friends and family use it to stay in touch with you, which means you’ll get all kind of messages, a lot of them with photos, GIFs or videos. The problem? Our phone’s storage is not unlimited (we wish) and sometimes we get that terrible “full memory” message.

In many cases, the files we receive via WhatsApp are responsible for the fact that we’ve run out of space to save more memes and cat GISs on our phones. Here we explain how to delete these files to recover the precious space you need so much, but we also teach you how to do a security backup so you don’t lose anything and most importantly: how to avoid this in the future.

First step: doing a security backup

Maybe you don’t want to keep any of the files that people send you via WhatsApp, in this case, you can skip this step. However, if you want to keep all the memes, Christmas greetings, prank videos and other files you’ve been piling up, it is possible to do a backup in a fast, simple and also free way.

The solution is Google Photos and its unlimited storage for life. To make a copy of your WhatsApp files you just need to open the app, log in with your Google account and activate the backup on the folders where the WhatsApp files are kept.

On the screenshots above these lines you can see the process. First, we open Google Photos and access the menu by clicking on the button with the three horizontal lines located on the upper left corner. Then, we access the “Device folders” where you can see all the image folders on your device. Here, you just need to select the folders WhatsApp Images, WhatsApp Video and WhatsApp Animated GIFs and that’s it.

Google Photos will keep a backup copy of all the files, but be careful, because it will usually do this when you are connected to a WiFi network, it’s best to wait for the copy to finish before moving on or you risk losing all the photos.

Second step: deleting photos and videos

Let’s get down to the messy part: deleting photos and videos to free up space. There are many apps on the Play Store that promise to clean our WhatsApp, but this is something we can do manually without any complications, you just have to locate the folders where WhatsApp keeps these photos and videos that are sent to us and delete them.

Depending on the phone model you have, it is possible that the design of the photo gallery changes, but basically, the steps you should follow are the same. The first thing you need to do is to go into the image gallery and explore all the available folders. Obviously, we are interested in those generated by WhatsApp, usually called WhatsApp Images, WhatsApp Videos and WhatsApp Animated GIFs.

Once located we just need to open them, select the content we want to delete (if you’ve done a backup you can delete it all without fear, your files are safe on the cloud) and delete it.

If you have been using WhatsApp for some time and have never deleted the photos and videos, you’ll probably gain a good share of internal storage and the full memory message will disappear, but remember, you should repeat this process periodically so this doesn’t happen again.

Third step: avoid filling the phone’s storage again with WhatsApp photos and videos

We’ve already explained how to do the backup and how to delete files, but we’re still missing the most important part: how to avoid filling the phone yet again with WhatsApp’s photos and videos. Don’t worry, the answer is not to uninstall the app, we just need to do some adjustments on WhatsApp.

Sure you are in many WhatsApp groups in which people send huge amounts of photos and videos in which you are not interested, but they get downloaded to your phone anyway, filling up your phone’s storage. What we are going to do is [limit the automatic download function](How to deactivate WhatsApp’s automatic download on Android) so not EVERYTHING you receive is saved, but only those things that interest you.

To do this, we have to open WhatsApp and go to the menu on the upper right corner, here we select the option Settings and then Data and Storage. In this section there’s a block called “Automatic download” where we can decide which files will be automatically downloaded depending on the kind of connection we are using.

Besides saving mobile data, with this option we can also enable the option not to download any photo or video on our phone automatically, we just need to deselect all of the boxes in the three sections (mobile data, WiFi and roaming).

Does this mean you won’t be able to receive photos? Absolutely not, as we said, deactivating the automatic download means we avoid the photos and videos saving but we can download them any time by simply pressing on them.

Ways of easily detecting malware on our computer

Unfortunately, we live in a cybernetic world in which threats are quite real. There are many kinds of malware that can affect the performance of our devices. These are diverse as well as its way of infecting us. We can find viruses, Trojans, ransomware… The truth is there are a lot to choose from. Many times we even have malicious files in out computers and we don’t realize it. In this article, we will explain how to detect malware in our computer.

Detecting malware on our computer

The computer is not working correctly

Maybe this is one of the most obvious. We use our computer and we notice something’s off. It becomes slower, some apps are not working correctly or we can’t even open some programs or folders.

So, if our computer has been affected by malware, the speed and functionality will be compromised. It is possible that this cybercriminals set programs to control our computer. This makes it function significantly slower.

Unknown Programs

Another obvious proof, is when software with an unknown origin appears on our computer. Icons can appear from nowhere on our desktop and we don’t know where they came from. Usually, this is some kind of malware we’ve installed unconsciously or that installed itself through some kind of virus.

So, it is convenient that, if we notice a strange program on our computer, we do an antivirus scan immediately.

Toolbars

In the same way, and this is something quite usual, we can find strange toolbars on our browsers. These tend to appear because of some kind of adware that has infiltrated our computer. Usually, these are very annoying when browsing, so they are quite visible and we will notice them immediately.

Sometimes we can disable these bars from the browser’s options. Sometimes it’s more difficult.

These can also be extensions that even control the web traffic and steal information from us.

Messages sent without our consent

This can happen both via email or social networks. In a previous article we talked about the Facebook video that infected those who clicked on a link. Usually, malware is distributed with a bait. If we end up infected, messages are automatically sent from our profiles.

This is something that can be pretty serious, since not only the malware sends messages in our name, but it also can affect, indirectly, other users that click on it.

These are some of the most obvious ways to detect malware. As we said, there are many kinds. The best thing is to always have good security programs and tools. Also, they should be updated to their latest version. Only in this way we will be able to face the possible threats that put our device’s working at risk.

But the most important thing is common sense. Most of the times it is necessary for the user to interact with the malware for it to spread. We should always be on guard.

The best Samsung TV of 2017 for each price range

Samsung is one of the most important TV manufacturers in the world. It is also the brand to look at in the smartphone market, as well as the one setting trends in the TV department. If you were thinking about buying a Samsung TV, then you came at the right time, since during these dates there are many discounts and offers for models that have been launched this year, so we will help you choosing one with this complete list of Samsung TVs sorted by price range.

The lineup of the best Samsung TVs of 2017 offers dozens of new models. Logically, 4K HDR TVs are the stars nowadays, but we can also find cheap and good-quality 1080p TVs that fulfill specific purposes: if you need a TV for the Nintendo Switch or for watching DTV channels in the kitchen or the bedroom, for example.

Let’s take a look at the best Samsung TVs of 2017. We have organized them by price range to make it easy for you to find the ones that best suit your needs.

As you will see, Samsung TVs have a series of letters in their names. If they start with UE, they are sold within the European Union. In this article, we are interested in TVs that say M or MU, as this means that they have been manufactured in 2017. For example, Samsung UE65MU6205KXXC. If they have a K or and J, they were manufactured in 2016 and 2015, respectively. QLED TVs are the exception, as they have their own names, they but always have the letter Q. If you want to know more, cluck on this link:

The best Samsung TVs of 2017

Almost every Samsung TV of 2017 is 4K, Ultra HD or UHD. The three terms are the same, and they tell us that their resolution is 3,840 x 2,160 pixels. 4K TVs can come either with or without HDR. This is a new technology that provides more realistic colors and better contrast between blacks and whites when we watch compatible content. Samsung keeps selling some 1080p or Full HD (1,920 x 1,080 pixels) resolution models, but they are not widely used anymore.

The display’s size and technology are mainly what set the quality and the price of the Samsung TVs of 2017. Along with the classic LED TVs, Samsung is committed to QLED, the brand’s proprietary technology that aims to compete with OLED, but at a lower price:

4. Less than €500

Is it possible to buy a 4K Samsung TV with HDR, made in 2017, for less than €500? It certainly is, although we would have to give up some things, such as a large screen size, QLED, 10-bit panels, etc.

Samsung UE32M5005

Let’s begin with the lowest budget. You do not want to spend a lot of money and you are not interested in 4K content, right? Take a look at this Samsung UE32M5005, it only costs €285:

It is a 32-inch 1080p LED TV with two HDMI and one USB connectors, the latter works as a built-in player, meaning that you can save your videos in a flash drive and watch them directly on the TV. It uses the Ultra Clean View technology to clean the image, and it has Samsung’s own frequency and contrast optimization technologies. This is a good TV to watch DTV channels, Netflix and Blu-ray movies, connect the Nintendo Switch, or put it in the kitchen or the bedroom.

  • Display size: 32 inches
  • Resolution: Full HD 1080p
  • Display format and type: 16:9 / LED

  • Price: just €285

If you are looking for a little more advanced Full HD TV, the 43-inch Samsung UE43M5505 slightly improves the sharpness when the image moves, it has better contrast, 3 HDMI and 2 USB ports, and it is a Smart TV. It costs €493 in Amazon.

Samsung UE43MU6125, 4K with HDR technology

Mission accomplished. Here you have a 4K Samsung TV with HDR, made in 2017, for less than €500. This model has a 43-inch display with 4K resolution and HDR10, the most widely used HDR standard. It has a slim design, the UHD Dimming technology that manages the brightness, color and contrast independently on hundreds of zones across the display, and full support for Smart TV with Smart Hub.

The Samsung UE43MU6125 TV has 3 auto-detect HDMI and 2 USB ports. It has a PQI rating of 1,300. PQI is Samsung’s own rating for measuring the image quality based on the brightness, contrast, color and frequency. The higher the value, the better.

The TV connects to the Internet via Wi-Fi and LAN, it is compatible with Wi-Fi Direct and you can send content from your phone to the TV through DLNA. It accepts hard drives and USB recording, and it has a gaming mode for consoles.

It does not have HDR optimization for the LED lighting nor the 10-bit panel featured on the most expensive models, so the HDR will not work at its best, but it is a real 4K HDR Samsung TV. Its original price point is €659, but you can find it on Amazon at just €489.

  • Display size: 43 inches
  • Resolution: 4K Ultra HD

3. Between €500 and €1,000

In this price range, we keep going for a basic 4K HDR TV. The LED panel will only be lit from the edges (Edge-lit Backlight and not Full-array Backlight that lights the display entirely from its back), so the HDR is less impressive. But the image quality will be highly acceptable when you watch 4K content.

Samsung UE55MU6645

The curved TVs trend has already died, if it ever existed, but they are still being manufactured. In fact, Samsung is the manufacturer that opts the most for them because it offers curved versions of almost all of its models. If you like this type of panel, here you have one of the most affordable.

The Samsung UE55MU6645 has a 55-inch ultra slim LED VA panel with 4K resolution and HDR, a PQI rating of 1,700 and technologies to improve the image like UHD Dimming or PurColor, the latter mixes primary and secondary colors to get better colors. The Auto Depth Enhancer creates a feeling of depth for the objects by adjusting the contrast. The Active Crystal Color enables us to improve the brightness and the contrast to get 20% more color while consuming 25% less power, as well as adding an extra light source in the form of a blue LED. In this model, the real frequency is 50 Hz, so it is not the best TV to play video games, as they require 60 Hz.

From this range all of the Samsung televisions they have the Smart Hub function with Tizen, that allows controlling all connected devices with a single command, including by voice or by cellphone. It is compatible with DLNA and Miracast.

It is the best curved television that you can buy for less than 1000€.

Samsung UE49MU7005

Here we have one of the best Samsung televisions of 2017, with an excellent quality / price ratio. It meets the majority of the high range requirements as a 10-Bit 4k panel: Samsung’s main image enhancement technologies, HDR improved with a better brightness and contrast ratio, and a video game mode.

All of the cables are hidden in the base, and with the One Connect mode all external devices connect in the same place, while a single cable goes to the television. The actual frequency at 4K is 60 Hz, enough for all kinds of content. The Samsung UE49MU7005 only costs 899 Euros. Take advantage of it!

  • Price: 899 Euros

2. Between 1.000 and 2.OOO

In this price range we have to start to demand aspects like the design and image quality. The 10-bit panel is essential, just like better brightness and contrast.

Samsung UE55MU8005

This model has a design that Samsung calls 360 degrees, because it is beautiful from any angle. With an ultrathin frame, an elegant base and a clean rear panel, where one does not see the cables, the design of the Samsung UE55MU8005 is spectacular.

Mounted on a 10-bit LED VA panel of 55 inches with 4K resolution that offers extraordinary brightness, which is perfect for using the well-lit environments. The HDR has been improved with that which Samsung calls HDR1000, but it is only HDR10 with a contribution of brightness (1000 nits) and for extra contrast, to strengthen the HDR effect. The current frequency is 120 Hz, but be aware that in the 49 inch model it lowers to 60 Hz.

The image quality is very good, better than the IPS panels, although like every VA panel, the vision angle is low, one loses image quality if one does not look at the TV from the front. Highlighted also for its low input lag,which makes it a good TV for playing videogames.

  • Price: 1259 Euros

Samsung QE55Q7F

The QLED technology is already here. Have Samsung completed the promise of offering an alternative OLED at a more affordable price? One an say yes, but with nuances. Thanks to the Quantum Dot, Samsung has gotten a color and contrast at OLED’s level, covering 100% of the DCI-P3 color spectrum, but with a very superior brightness. The HDR is also very spectacular. But it is still LED technology, and that is noticed in the blacks, more washed out than the OLED, and in the vision angles, better than in LED but still far from OLED.

If you have the budget, it is worth it to buy QLED TV before a LED. The Sansung QB55Q7F is possibly the lesser Samsung 2017 TV in terms of quality / price. Mounted on a QLED 10-bit screen of 55 inches with 4K and improved HDR10. The brightness level reaches 1500 nits, and implements the most advanced Samsung image technologies, like Q Contrast or Q Color. Reaching the Ultra HD Premium standard, it comes with 4 HDMI, and one can hang it on the wall like a painting (it doesn’t stick out).

With respect to the A8 and Q9 it has slightly less brightness, but as we have said about this appearance is a fair amount better than an OLED, so it stays at a great level. And the price is excellent, right now you have it on Amazon for only 1748 euros. And on top of that you get a free Samsung Galaxy S8. Here you have the details.

  • Screen size: 55 inches
  • Resolution: UHD 4K (3840 x 2160 pixels)
  • Screen type and format: 16.9 / QLED 10-bit

  • Dimensions and weight without support: 122.5 x 4.5 x 70.4 cm / 21.2 kg
  • Price: 1748 euros

1. More than 2.000€

In Samsung’s high range you will enjoy the best image quality with some amazing levels of luminescence.

Samsung QE55Q8CAMTXXC

On icisnet we had the opportunity over the past week to try the curved QLED Samsung QE55Q8C television. We loved its design, the brightness and the image coloring, capable of reaching a luminescence of 1500 nits, and the HDR. As is logical on all the panels except the OLED blacks are not perfect, and we also note some light leakages. But the improvement with respect to the LED is spectacular.

We also liked very much how it rescales 1080p content. Not as much the TDT standard or the DVD, but we are talking about rescaling a resolution 16 times lower. The distance command One Remote has seemed to us the best command that we have tried, and also highlight the good performane in videogames, with Steam streaming from the integrated computer in the TV.

One of the best Samsung TVs of 2017 if we take into account that the Samsung QE55Q8C costs slightly more than 2000 euros, something unthinkable in panels of this quality in a couple of years.

  • Screen size: 55 Inches
  • Resolution: UHD 4K (3840 x 2160 pixels)
  • Screen format and type: 16.9 / QLED 10-bit

  • Dimensions and weight with support: 1225.3 x 790.2 x 300.8 mm / 20 kg
  • Price: 2112 euros

Samsung QE65Q9F

If money is no issue, this is the best Samsung TV of 2017 that you can buy. Although there is a model of 88 inches, we stay with the Samsung QE65Q9F of 65 inches, not to exceed the figure of 4000€…

Its price is daunting, but it can compete with the most powerful OLEDs on the market. Its QLED screen of 65 inches in mounted on a Super VA panel with a maximum luminescence of 2000 nits. It is ideal for watching TV in a bright room, like a bar or family room.

The Q Engine technology, combined with the Quantum Dots and an improvement of the vision angles of the Super VA panel, get an outstanding color accuracy and HDR (including the support of the new HDR10+), which even beats the majority of the OLED. Its weak points are the same as in the rest of the QLED range (lower angles than OLED and blacks are not perfect), but we are talking about a true alternative to OLED, at a lower price. Impressive!

  • Resolution: UHD 4K (3840 x 2160 pixels)
  • Screen format and type: 16.9 / QLED SVA 10-bit

You can then choose from all the tutorials available for the selected computer, each of which relate to a different hardware component (e.g. Fan for the fan, Hard drive for hard drive, RAM and so on), and view all the information you need to carry out the task.

Another site that I recommend you visit if you’re about to take apart a laptop is Future Proof , which contains hundreds of manuals on maintenance and repair of various models of laptops / notebooks. Again, it’s an English site but their contents are also useful for those who don’t understand the language very well. Don’t forget to take a quick tour of the manufacturer’s website for the computer you want to disassemble (e.g. HP , Dell , ASUS, etc.) to download the official manual. Although it’s difficult to find detailed instructions on how to disassemble the computer, it may contain technical information and information about the laptop components which you might find useful. Finally, I recommend the timeless YouTube. Where the official guides and manuals don’t help, someone may have already dismantled their laptop and they may have published a video on the net to explain how it’s done. Search for [model of your laptop] disassemble or [model of your laptop] upgrade RAM, [model of your laptop] repair, etc. in the video search and you’ll almost certainly find something interesting.

However, there is not always avialable the required space to put a TV of these size, so you will have to find an adequated size for that specific space. One of the best alternatives are those between 42-46”. This is why we wanted to bring you a selection of the best TVs between 42-46” so you can make the best purchase this new year.It is the ideal size for a TV that is going to be in the living room.

The 1300 Mhz PQI offered by the Samsung UE43MU6105 brings a great fluidity at the moment of showing action or sports scenes, where the fast movements tends to create trails that reduces the image sharpness. By having a more refresh frequency, these images appear much sharper.

The Snapchat case, or why developers should pamper Android users

Snapchat is a clear example of what can happen when you dump the Android community. We all know Snapchat is going through hard times in terms of economy and user level, its financial results from Q3 show it. The arrival of Instagram Stories gave the yellow social network a blow that sent it to the pit-bottom and it hasn’t come out yet, I doubt that it can, especially in the non-US market.

Android One of the app’s main problems is the fact that its Android version was really bad. Snap wouldn’t update the app with the same care it put to the iOS version, it would even launch new features on iOS that took weeks and even months to arrive to the Android version. Moreover, the quality of the image on Android was terrible, while on an iPhone you would get an excellent image. The app was pure trash, nothing more.

Recently, Evan Spiegel – he said it himself, that he didn’t want people from poor countries like Spain using Snapchat – said that during next year he would put all of his efforts on developing a new Android app from scratch. Good news, no doubt, but too late. Spiegel himself confirms this when he says that most of the users that registered on the app in September did it on Android: “I wish we had done it before”

Android users are not less important than Apple users

Android In fact, we are many, many, many more. Snapchat treated Android users as irrelevant and that meant leaving behind a huge market niche, full of thousands and thousands of users that, because of the company’s own negligence, don’t use the app, since it doesn’t work as it should, considering that Android devices are quite more potent than Apple’s devices.

Snapchat is the perfect example of how not treating Android users as they deserve is the same as plummeting. But this is not the only example, this is not the only app that has treated Android as a secondary OS. Nintendo launched Super Mario Run on iOS and made us wait a lot of time before arriving to Android. Do you know what happened? It was a complete success, so their next two games, Fire Emblen Heroes and Animal Crossing: Pocket Camp where launched in both systems at the same time.

Still, there are apps that still bet on launching on iOS first and then, do Android the favor of being in their system as if we had to beg them to give us our share of apps. Trivia HQ or Monument Valley are two clear examples of this.

Android is a much more extended system on a global level

Android

Data speaks on its own. On the chart above, extracted from Kantar, you can see how, except in the United States and Japan where the fight is fiercer, Android is the most used OS on the main global markets. An app, company or service that ignores Android users would be losing a huge amount of earnings from ads and users. In Spain, specifically, Snapchat looked down on 90% of the users. This and digging your own grave are basically the same.

And yes, I agree with the fact that developing for iOS is “easier” because there are only a few devices on the market and also I agree with the fact that Apple is the leader in sales globally, but only in terms of brand. Apple and i0S can not be compared with Samsung and Android on that level, because only Apple has iOS, but Android is on Huawei, Samsung, LG and in every other Brand whose logo isn’t a bitten apple.

Android Not to mention the fact that Android allows to develop phones in the middle and lower range which allows to bring smartphones to poorer or developing countries. From an exclusively consumerist and mercantilist point of view, a company is interested in developing a good app for Android, because we are speaking of an OS that reaches the entire world. And we are back to the same: ignoring Android is like ignoring almost the whole world and Snapchat is the perfect example.

Developers need to start betting on Android, they should treat us, the users, with the same pamper they treat iOS’. Yes, we agree that developing iOS is easier, but developing on Android is synonym of global expansion, a bigger audience and better results.  Snapchat may be late but let’s take it as a warning of what can happen if you ignore Android.
