After more than a week of using my 820 i noticed a problem.

I took my phone out of the pocket an had to insert the PIN. Was afraid it's a loose mircroSim problem.

Yesterday the phone was lying on my desk next to my computer. I noticed something was going on at the phones display. And than i saw the reboot.
It happens once in two days and really feels random

I heard about the reboot problems of the 920. Might this be the same issue?

I had the 820 and I had several freeze ups but no reboots. I switched back to Verizon and picked up the 822 and so for a very stable device no issues at all. I find the battery life to also be superior to the 820. It could be something with GSM devices causing those issues. I know the 8x on all carriers is having a major reboot issue.

No issues of the kind on my AT&T 820.

I've not seen any reboots yet but it's only been a couple of days.

No issues on my AT&T Lumia 820

No issues on my 12 day old att 820

My 820 has rebooted once a few days ago.

Same problem here on my Lumia 820.

Have it now for 8 days. In the first 4 days it rebooted approx. 5 times. Last days only every second day.

I did already a factory reset, but didn't help.

I would compare apps and see if any are common amongst the phones that reboot

It starts to annoy me! Missed a SMS yesterday because the phone rebooted and was asking for the Pin.
And now it lays on the desk again in standby and the nokia letters came up.

Only a few apps are allowed to run in the background:
- Weather View
- Battery level for WP8
- Mail every 1/2 Hour
- Skype and Facebook integrated to the system

WiFi and 3g turned on. Location, NFC, Bluetooth off.

This must be a really bad software bug!

This Problem is related to WP8, not the hardware.

I disagree that it's a WP8 issue; I've now had 3 WP8 devices (a Lumia 920, an HTC 8X, and a Lumia 820), and while I had some issues with the 920 (loss of connectivity, overheating) I've not had a single reboot or freeze with any of these devices. If you have a phone which is rebooting, take it back. Get a different unit.

Well my 820 shutdown/rebooted for the first time yesterday. I also noticed my battery was draining very quickly. Hopefully it's a one off, and not a sign of things to come. :/

I also noticed my battery was draining very quickly.

I noticed that too. Like 1% in 2 minute. But only had the battery problem once and played with some apps before. That is why i thought it would be a app related problem.

Mine wouldn't sync my windows live account, so I did factory reset to try again, now it's stuck on the Nokia logo. Ive tried soft and hard reset multiple times. And it just goes back to the nokia logo and stays there, I have it on the charge cable and its just been like that for an hour now.
