galaxy nexus i9250 constantly rebooting
1 Since a week my Galaxy nexus is rebooting 5-10 times a day.
2 And its at some times very slow
3 Further more when i start the phone ( from sleep to active) or a app it goes on andscreen goes off for 1-2 sec and proceeds with working (slowly).
After re-entering sim code it will start up but after a while all happens again in a matter of time.
There have not been any additionel installation of software before this happend.
android 4.2.1 no 4.3 update yet
(europe i think)
please let me know if you have a solution.
Is it software hardware???????? i did 3 factory reserts but did not work....
