okay everyone, i'm concerned. i got my infuse about 2-3 weeks ago from target mobile and was working fine. but now, it seems to go crazy on its own. sometimes it will hit the app button, then the home button over and over again until i have to just take the battery out. it does this for alot of things. when trying to edit my alarm it will start changing the numbers randomly. this is not everytime but it happens too often for me. also, my calls randomly drop or i will be on a call and the person i am on the phone with all of a sudden can't hear me. has anyone else had this problem? what should i do before i take it to get looked at. i did drop it and it has slight physical damage but it wasn't anything major. i fell onto a carpeted floor. thanks so much for all of your help in advance!
