Re: I know my boyfriend keeps hacking my phone
Welcome to Android Central! Totally agree with the above. If you don't have a screen lock set (with a PIN or password that are hard to guess), and if you let other people have access to your phone, then you leave yourself wide open to various shenanigans. If you do have a good screen lock set up and never let other people set up your phone, then either your BF is Elliot Alderson (Mr. Robot, go watch the show if you haven't, a masterwork) or there's some other non-sinister explanation for the buggy behavior.
I wish there were some way for Google and phone manufacturers to label system apps in a way that would calm people down, like some footnote saying "THIS IS NOT MALWARE." InCallUI is the User Interface while you're In a Call.
