Android 4.4.3 It has already begun to be distributed through the Internet to several smartphones, including the Nexus, the Google Play Edition smartphones, and also some Motorola. Although it seems like a minor update, the truth is that it solves two very important security problems that existed until now, so it is going to become an essential update.
It seemed that 4.4.3 Android KitKat It could be an update that happened without pain or glory, and more when it seemed that Android 5.0 could arrive soon, as at the end of the month. However, it will be an essential update for many smartphones, as it solves some very important security problems that until now existed in previous versions of Android.
One of them had to do with the Superuser file directory, also known as the Root file directory. A system component that is in the Root directory and that was used so that an application could secure files stored in the SD memory, precisely allowed by mistake to give write permissions to new applications without verifying the permissions of these apps. In other words, any application could modify files on your mobile. This would be one of the security errors that would be fixed with the new update to 4.4.3 Android KitKat.
The other security bug allowed the smartphone to give a user Superuser permissions when the smartphone was connected to the computer using ADB, even though the smartphone was not rooted. This could be useful if we did not want to root the smartphone, but we did want to make backup copies when the smartphone is connected to the computer, thanks to the fact that this problem allowed us to obtain those Superuser permissions. However, a user who did not know, could run an application capable of ending the smartphone forever. With Android 4.4.3 KitKat, this security problem has also been fixed.
The new version of the operating system is already coming to the Nexus 5 and Nexus 7. Also It is possible to install Android 4.4.3 KitKat even though we have not received the installation notification, as is the case with the Nexus 5, as we have explained today. To the Motorola the new update will arrive in the days remaining this week. For now, it seems that those will be the first to have Android 4.4.3 KitKat. Most likely, the Samsung Galaxy S5 will be next, as it has long been rumored that Samsung was already working on the update.
