thanks for your great post above. Great recommendations! Still, If have said it before and i say it again, i do not have a great feeling regarding 1Mobile. That an app is on Google Play and on 1Mobile and that these require the same permissions or are the same version is no guarantee that they are not modified and safe. Even more so, Google’s introduced a some kind of app verification which checks for malicious apps from outside the Play Store that only works if you use Google Play services installed.
On mobile systems like Android it is crucial for your security to only install apps from trusted sources. No, everybody should be able to install from wherever he/she likes, but is still do not recommend 1Mobile for anybody concerned with device security and privacy.
It is perfectly fine to stay away from Google and i understand all the reasons to do so. But by installing apps from such sources, i believe you but your privacy at risk more. And privacy is the reason to avoid Google in the first place for many.
