It was working fine until last week, got one messsage "android phone stopped working" once, then I wasn't able to hear when calling or recieving a call. Everything else was still working.
Now, two days ago I turn it off and on, the phone goes up to locked homescreen and then screen goes black and restarts automatically. This repeats indefinetly, if I don't turn it off as soon as the homescreen appears, I have to remove the battery because power key doesnt responds.
I got the phone from an ebay seller
I live in Peru.
Excuse my english.
OK... I will tell about my case.
I bought the ZR in august 2013. It was rooted and flashed to 4.2.2. Everything worked fine. Until January 2014.
The first problem was - Silence during calls. I was not able to hear something. And my voice was not heard on the other side. In tests microphone and dynamic worked fine. External dynamic and earphones did not change something - silence during call remained.
After some time (phone was on and off... and again... and battery was removed some times) problem disappeared. But after one day it came back. And disappeared again... and came back... and so on for few times. The other functions all the time worked good. I only was not able to talk during calls.
I flashed the phone to 10.4.1.B.0.101... and to some previous firmwares by Flashtool. But nothing changed.
The next stage after some days was: I turned the phone off. And after turning on it was not been able to see the network. And wifi was not working. I went to settings and saw - IMEI and MAC have disappeared.
I flashed phone to 10.4.1.B.0.101 again. Nothing changed.
And after a little time phone said something like: "the system application stopped" ( I did not remember exactly). And than after rebooting it went into:
"the phone goes up to locked homescreen and then screen goes black and restarts automatically".
I think our cases may have one problem in basis. And I think the problem is in hardware. Because i flashed my phone for some times and flashtool did not said something about errors and drivers was ok.
I will go to service center. But I think they are not very good in fixing phones here...
