HTC ONE X camera problem :/

[aliciafrances]

Hi

I was using snapchat today and it crashed whilst i was sending a video.. i turned my phone off then on again. Snapchat doesnt work anymore and just comes up a yellow screen, and whenever i click on the camera app it doesnt do anything.
So i tried instragram and it says 'cannot connect to camera'...

you can try a hard reset, press the power button until it turn off if it doesn't work try a factory reset
