Hello everyone. A couple days ago I was trying to download something off of the internet on my phone, a samsung galaxy s4, when i sae this thing called phone booster. I thought this would help my phone but it didnt. It pretty much controls my phone, and wont let me use google play, doesnt let me have a lock screen, wont let me be on the internet for long, and basically rakes the phone basics away from me. I cant uninstall it because it says its a device admin, but when i go to remove it from device admins, it doesnt show up. Any tips on how to uninstall or get rid of it?
