until i pull the battery but when i put it back in it starts doing the same thing..please help before my new phone turns...

my phone is doing something just a little different. it turns on just fine but then it just starts to cycle bringing up random $@$* like my camera then a video then maybe my gallery. but nothing stays on long enough no matter what i touch. i cant do anything but shut it down if im lucky enough to hit off as it passes me up. so i usually just pull the battery. please help
