I opened up my phone this morning & there was a white screen with a little loading bar at the top which led me to the play store. I tried to see which app was doing this by clicking the screen button but it has no title on it. Please help me!
Welcome to Android Central! What do you mean by a white screen with a loading bar? Did it look like a popup window? Was there an actual download/installation notification on the status bar? If you only saw the bar on the window, then it's likely adware that's trying to lure you into tapping something that actually will install something (that is possibly malicious).
