Recently, when I receive a text and open up the keyboard to type a response, the touch screen freezes. It doesn't respond at all until I turn the screen on and off a few times and then slide unlock it. It's getting really frustrating because instead of being able to reply to a text in a few seconds, it can take up to 5 minutes. It's just really inconvenient. Has this ever happened to anyone else? Should I call Verizon? My phone is still under warranty... I'm just afraid of getting a phone with even worse issues.
