Sony M2 restarting when not in use.

My phone when left alone decides too restart itself constantly. Sometimes goes onto the optimisation android screen and have too wait till it finishes. This drains the battery quite quickly which leaves it dead in a couple of hours. Using it however works perfectly!

Hi @magoostew75, I am sorry to hear that.

Could you try removing the SIM- and SD cards if you have such cards mounted, and then see if it still restarts? In addition, did you notice that this behaviour started occurring after you installed a specific app, that it occurs after using a specific app or something along those lines? 

I am looking forward to your reply so that we can troubleshoot further!
