Xperia Z keeps switching itself on and off incessantly

[fbell14]

Hi,

My phone has all of a sudden just started to turn itself off and back on again constantly, I have just rebooted it by holding down volume and power it and it has thankfully not switched itself back on, is there any way this can be fixed? I have not plugged it into the charger as this causes the prpblem to continue.

Cheers.

My m5 has suddenly started to turn on/off. Done a full repair and still keeps doing it. It re boots, half way through it crashes, then starts normal again, then turns itself back off again. I think it's a battery problem. Its just randomly started. Why?

My phone software updated and now turns off anytime I start a app or do anything. I didn't even get asked about updating the software. Android version 5.1.1 have sony broke my phone with this update?

Ami3 did you get it as a new phone? if you did phone them and ask if they have ever heard of the sale of goods act if they still refuse to help go to trading standards.
