Greeting. I just get a new phone. It has these two apps:
Clean Master (by Cheetah Mobile) CM Security (by Cheetah Mobile)
I know that these two apps takes user information without consent. (For those who wants to look it up, here is information from India.)
Of course, I remove these two apps, but how do I make sure these two apps are completely removed? In other words, using the regular way of removal (Settings -> Apps -> select an app to remove), does Android (the Operating System) remove everything an app install? (Hopefully the installed app will not secretly install additional apps without my knowledge.)
I have searched the web, but maybe my Google-ish is not good, so I don't find articles about this topic (checking if an app is completed removed). I have heard that one can use WireShark to detect the data usage of mobile phone, but I just want a simple way to check. I don't want to set up a lab to do so.
