So, I recently got my Lumia 920 three days ago, and every night since then, it shuts off and I have to turn it back on with a soft reset.
This mainly seems to happen overnight when I leave it charging. I know a lot of others have had this issue, but to me honestly, it doesn't seem like that of a big deal.

My main question is that, if I keep my phone without exchanging it for a new one, will this problem lead to greater issues? I already have everything set up and the AT&T store is an hour away.

Most likely cause is a WP 7 legacy app. Go through what you've recently downloaded and try uninstalling some. Usually games are the culprits.

Edit: and the accuweater Nokia app for some reason.

Nope. I switched from the 820 to the 8X. Exact same apps on them. Used to have the frequent 'shut downs' twice a day on my 820, after switching to the 8X, not a single reboot. I think it's OS wise and Nokia needs to fix it.

One of the reasons I made the switch was because it would go into a dead state ever too often, and why should I check my phone every 10 minutes to see if it died?

See my edit for another culprit. But I've had it occasionally, and it has always been related to an app.

Do you know if your 820 had portico? I know the 8x have it if its not acting up?

I think that you have good one ... but there is a plenty of similar claims applied for HTC 8X

HTC 8X reboots: Reboots

HTC 8X died on its own: HTC 8X Died On Its Own..

I thought that it may be an app causing it, I will run through and delete some of the apps I downloaded on the first day I got it.
I'll keep you updated!

Yeah, lucky me then! Had enough problems with my 820, if the reboot problem had surfaced on my 8X, I'd probably have gone back to iOS.

Never meant you didn't have problems, but my solution was primarily intended for 920 users.

Try turning off SIM card pin login, and if it is turned off and you still have the same problem. Then try switching the SIM card with a new one.

Interesting thing happened today for me - I had to change my wifi password and forgot to update it on my phone. It "locked up" several times in the past couple hours until I updated my wifi connection on my phone as well...so maybe it has something to do with wifi connectivity as well - eg. if it temporarily loses wifi and attempts to connect again, and then "locks up" as a result of this.

My pre portico 920 never shut down, but my portico 920 shuts down daily

Does it do it if you keep Wi-Fi off ?

In my case, freezing stopped when I stopped all background services including battery sense and amazing weather hd.

920 here and have been seeing this shutdown you described. I only gave 3 apps or so running in the background and I haven't downloaded any new apps. Although, I am certain this only started after the last phone system files (display and one other) update.

Apply GDR2 update. It will resolve the problem. You can download Nokia Suite and apply it or take it to Nokia Care to apply it for you.

This update fixes the problem and add more features.
