There has always been a lot of music playing with the lyrics that Android devices are very vulnerable since Play Store is a strainer of malware. In its latest updates, substantial steps have been taken to ensure that it is a much safer environment, something that has raised very different opinions. The disadvantages are among the most advanced users who know how to protect their equipment and understand that this is putting doors to the field. The favorable ones among those who previously criticized him for openness.
The truth is that most of the Android malware did not come from the Play Store itself. When we install an application we are notified that we do so at our own risk and we are informed of the permissions that we are giving to the software and what type of information we will share with its programmers. Thanks to this freedom we can test applications in beta phase and get adjustments and customizations that small developers do.
The problem is that people don't like to read the terms and conditions and sometimes they install the apps a bit like crazy. We have said it many times, if you do not have a strong knowledge of the Android environment you should take certain precautions, including installing applications known or recommended by friends.

To silence criticism somewhat, Google has taken the measure that if an application is installed from the Play Store it will also be updated from there. This makes you have to go through your malware filters again and the risk is reduced. These filters are also getting thinner. Before, this was not the case, and when updating an already installed app, they could introduce a virus or steal all our personal information. Sometimes it was really easy since many users have automatic updates turned on. With those that we install from unknown sources, that barrier will not exist but we will be notified that they require an update, so be careful.
When we acquire more freedom we always acquire more responsibilities. It is a proverb repeated over and over again by Android fans, but it is still true.
