**FIXED!** I have Malwarebytes installed on my phone, I'm pretty sure its seriously malfunctioning, I get several messages saying "Unfortunately Malwarebytes has stopped working and needs to close" per day. I can't remove it from the APP MANAGER under the settings menu, both the FORCE STOP and UNINSTALL buttons can't be selected. Any help appreciated! The phone is a Galaxy Alpha. THE FIX: If anyone else has this problem go to SETTINGS > SECURITY > DEVICE ADMINISTRATORS > and deselect the app.
