M4 Aqua dual SIM problems after 7 months

UvB — Thu, 12 May 2016 12:39:04 GMT

Hi, After 7 months of use of my M4 (dual sim), suddenly the phone started to restart and kept restarting. After half an hour or so it finally was OK. I also noticed that bluetooth wasn't working. After a reboot (power and volume down button ten seconds), bluetooth worked fine again and stoppped after a few hours. Later I noticed the same with wifi. Not working anymore.

I had problems with my first M4 that was replaced after a few days too.

I'm starting t have serious doubts about the M4 quality.....

I hope people here can help me what to do.

Remove the SIM card and check if the phone reboots if it doesn't you will need a new SIM card

as for the other issues, repair the phone with XC to narrow down the problem
