Hi,
I bought my phone a few days ago.
The phone starts and works well in a few minutes. Then the phone will restart. Just today it safely restarted 50 times.
Do you think it is hardware or software? I have tried to factory reset the phone, and add the latest Android available for the phone.
Help, please.
Hey there
Take the sim out of your phone and then use your phone for sometime
See if it restarts again and again
Thanks for the quick reply!
I test it and get back with the results.
Hi,
Unfortunately, the phone will restart even though I removed the sim card.
Go for a software repair
After repairing your phone, don't install any app on your phone ( not even a single app ) but observe the behaviour of your phone

Backup everything as it will erase all data on phone (sms, contacts,apps)
Update/Repair your phone via PCC or SUS
PCC (PC COMPANION) – Repair your software with this .First do the setup without connecting your mobile to pc.(only connect when you are asked to).

Should I continue to have the sim card out of the phone?
Thanks again for quick reply!
No, you can put it back 
Now i will reply tomorrow
Good night 
Do post the results
Unfortunately, the problem remains.
treb1120 we have ruled out almost everything. What's left is the hardware
Now you need to go to service center in order to get your phone examined. They would tell you the cause possibly
Hurry. if it's a hardware problem, you could get a replacement (iff your phone is not more than 7 days old )
Ok.
Again, thanks for your help.
