Tablet without noticeable reason began randomly shut down by itself.
Sometimes in an hour goes off 5-6 times, and sometimes working 5-6 hours without turning off.
Tablet can not be sent to the service because it was purchased abroad.
On it is the original untouched Android 4.2.2.
I tried a factory reset and re-flash with the latest android from sammobile.com , but it didn't help.
Does anyone has a similar problem or solution.
Thanks in advance
