Sense I have updated my Ipad my back camera is blurry and front isn't , need help on the back camera.

Close the camera app and reboot your iPad.

Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the camer app and then swipe "up" on the app preview thumbnail to close it.

Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

First make sure the lens is clean. Next try a reset, press and hold down both the power and home buttons for 10-15 seconds till the Apple logo appears. Release both buttons. Wait 12-20 seconds till your iPad starts by itself.
