hi. since i have updated my new ipad's ios to version 6 ,it restarts in many programs such as face time,settins ,ibooks,foxit pdf,safari,puffin,... some times the screen gets black and in the middle of the screen the circle rounds and after a few seconds it ask the password and the problem solves. but some times a program closes automaticly and i reopen it , it does not run and closes again.then it restarts and after a few seconds apple sign appeares and takes about 20 to 30 seconds to ask enterance password. i updated to6.0.1 and nothing changed. therefore i restored it and i did not return the backup to the device. i installed some programs and the problem appeared again.now i have 24 Gb free space is there any hardware problem with my device? my device is wifi 32 Gb 4g is there any event viewer to see what happens to the device? is there any way to test hardware?
