Why is Nexus 4 acting weird on Android 4.4?

Question

Android

After updating on the Nexus 4 phone to Android 4.4, I notice strange behavior of the phone, the phone reboots periodically. The phone did not fall and before that it worked fine on version 4.3.1.
Tell me a step-by-step manual or where to look to fix this situation.

Answer 1

look for info on http://4pda.ru/ everything is written in detail there

Answer 2

Updated how? I have the only oddity that I flashed through adb, and yesterday an update came over the air, with a hint that I have a lower firmware, the bodies rebooted and flashed from scratch, there were no more glitches.

Answer 3

I also notice oddities in my work. Updated over the air. Once, for no reason at all turned off. with a charge> 50%, and did not turn on for about 5 minutes (naturally, I tried to turn it on). Today, for some reason, the alarm clock did not work ... I can attribute it to the fact that I poked something (but what is it), and he decided not to wake me up anymore. Came to work - set the alarm for the near future - it works. It is also alarming that the phone began to charge longer than usual. For 2 hours from 20% charged only up to 60%. And I can not say that the battery from this holds longer.
In general, I don’t pay much attention to all this yet, but there is still something in it.
