My phone has developed a problem where it has a severe lag when using backspace on Facebook in Chrome. The vibrate feedback doesn't vibrate in time to my presses so there's something wrong there. I've logged in and out, cleared the cache and reinstalled the Chrome updates but nothing. It doesn't happen on any other app or website, bizarre!

Also Snapchat. If I put the flash on and try to take a photo it often won't take and the flash will just stay on until I exit the app, and the camera button on the side of the phone only works occasionally. I can't work out why. I've reinstalled it but it still doesn't work.

My camera is the most annoying part, it's barely worth taking photos. The back camera has a 3 second delay (not timer) before saving the photo and most of the time it comes out blurry I have to be extremely still for about 5-8 seconds without a timer on.

The front camera is awful, it looks like you're taking photos in the dark unless you're outside in daylight... It's one of the reasons I got the phone, for front facing photos but everyone comments on how awful it is!

If anyone can help I'd be grateful, or advise if this is grounds to get a better phone while in contract.
