Lumia 900 will not stop freezing.

So I don't know what's going on but my Lumia 900 will not stop freezing. I restarted it and it boots up to the start screen but the second I tap any of the tiles or buttons the phone locks up. The music tile still animates, the battery icon still flashed the charging symbol but no touch registers. Hitting the power button turns the screen off, hitting it again goes back to the frozen start screen. Sometimes it just freezes without me even touching it. I just now managed to get it to go into the pictures hub, but then it froze again. Can anyone help?!

Have you tried doing a soft reset? Try doing that and see if it solves the problem otherwise you might have to do a hard reset

Oh I'd been soft resetting time after time, it didn't work. It finally stopped freezing, but god it was frustrating.
