[AC Question]

Umm heres one you might not have heard of.

OK so I know apps can automatically to your home screen or other pages when installed. My HTC One m9 is adding apps to a side screen when they are OPENED. everytime I open an app. It's extremely annoying. Help....

Welcome to Android Central! What do you mean by a side screen? Do you mean one of the other homescreens that you get to by swiping horizontally? Or are you talking about the Recent Apps list?
