I've noticed in the past two weeks there has been a serious lag issue with my touch screen. When I slide my finger for the slide lock, there is about a 5 second lag. I received a phone call this morning and as I was trying to hang up, I had to press the "end call" button three times. The same thing happened when I tried to hang up a call that I initiated. Has anyone else had this problem? Do I just need to turn my phone off and let it get a minute of rest or something? Last week my phone just froze up and I had to take the battery out. It did that twice in the same day and I had to take the battery out twice in ten minutes time. I got my phone towards the end of October and I really don't feel like trying to get a new one.
