Hi, today my phone started acting kind of weird. It began to vibrate randomly,screen go black and return me to the main home screen no matter what I was doing. I could be browsing the internet or just sending a text, and it will randomly do this. Its getting to be kind of a nuisence and was wondering if anyone has had this problem before. I have reset the phone and removed the battery as well as check for updates which it found none. I am using this phone through Straight Talk if that helps you at all.
