Why does my Lumia 640xl keep switching itself off

Not much else to say. It just keeps turning itself off, and so I have to enter my pin again.

Lock screen or Power Off "turning itself off"? My Lumia 925 did it a few times, it would randomly have my lock screen go on when I upgraded to the latest update before Windows 10, I'm assuming it's a software issue, not a hardware issue.

Yes Knuckles245, it actually powers itself off. I have only had the phone for a month, and have not updated software or anything else.

Have you tried what Amit suggested? If it's possible to get a replacement, if resetting doesn't work, that's the route I would go.

Thank you all for your kind advice.
And thank you Lumia_930 for the link you posted above. Yes, the phone did need a "critical update".
If anyone else has the same problem, the link you sent was so easy to follow.
Hopefully my phone now wont re-boot 12 times a day !!!!!
Thanks again.

My AT&T 640XL was resetting it self last week, but a reset seemed to help. This week it was having reception issues, so I have a replacement coming in a few days. I hope these fixes get pushed out quickly, as AT&T takes forever to OK any updates.
