Sometimes, I cannot get the screen to respond to anything I do except for the hard buttons at the bottom. The phone isn't even activated yet and I have only installed a few apps. The phone is brand new and has never been rooted. It drives me crazy that the screen wont respond and I have to use the on/off button on the top of the phone to get it to do anything. Once I do that, it usually works.
What are my options to make this stop happening?
PS- I didn't get the phone from the store otherwise I would just go back... I got it off of craigslist.
