My new Lumia 920 has, in the two days since purchase, twice shut down for no reason. The first time it happened about three hours after powering it up.  The second time, this morning, it happened after being up and running for about 30 hours.  I am unable to discern a cause. It just powers down of its own accord.  Holding the power button to start it back up does nothing.

To power back up take the following steps:

Hold volume down button, power button, and the camera button down at the same time for approximately 10 seconds.  The phone will vibrate at that point.  Release the buttons and the boot up process should start. I've experienced no data loss or configuration settings change or loss from all this.

I hope Nokia will push a firmware update, I assume it's a firmware issue, ASAP.

Is your sim card new or have you had it a while?

Was it originally a micro sim or was it cut from a standard sim?

Personally i've yet to suffer any random reboots or shut downs on the 920 that i've had for a week now.

[SentientCoder]

New SIM card, which I got with the phone. Not sure about micro or standard.

[psychomania]

That should rule the sim out then with it being new. Older or badly cut sims often cause behaviour like this but shouldn't happen with a new sim.

Have you tried a full device reset (via the about menu in settings)?

With it not being an issue that affects everyone a firmware update may not solve it, could be a software or a hardware issue.

I'll try a full device reset later today. A co-worker who also has a new Lumia 920 related to me he has the same issue but in his case it is shutting down more frequently. So I expect this issue will come up more frequently in the coming days. So I am hopeful for a firmware fix.

[SentientCoder]

Well a full on reset to original, out of the box state does not rectify the problem. Oh joy.

I'm going to live with it a few more days and see of Nokia steps up with a fix or an explanation or even an acknowledgment the problem exists. If not it's back to ATT with this unit. I've got 10 days remaining to return it so a few days wait is ok for now.

Did you try changing the Network setting from LTE (if selected) to 3G ?

[pmaroun]

How do you change the network setting from LTE to 3G?  I am on ATT--I see no such option.

[farby]

To turn off LTE check under Settings-->Mobile network-->Highest connection speed. Setting this to either 2G or 3G should disable LTE.

Hi guys,

There have been numerous reports of issues reported by customers who have bought a Lumia 920 from AT&T, in which case the cause has yet to be found. As you have a returns period, in all cases, I suggest returning the phone to your point of purchase.

[CDLumina920]

same issue. Followed the same troubleshooting that you did to no resolve. Nokia needs to fix.

[inbruCHes]

Same happens here. My Lumia 920 shuts itself down at least once a day, which is really painful. Is there really no solution to it?

[Biff_Pocoroba]

Mine does as well.  Nearly every day for a month since I've owned it.  Very embarrsing when showing iPhone users how great the phone is only to have manually reboot.  Terrific phone but definitely could go without the "feature".  Pleading for a firmware fix.

I know, it's a real pain. Has happened to me too that I was bragging about my Lumia and it was just dark. Even worse, at the time I didn't know how to soft reset

Press the Volume Down + Power switch for about 10-12 seconds ..

[inbruCHes]

Thanks. Had it figured out, but only after embarrassing moment...

Seems most of you are not using nokia supplied charger. Try to use nokia power charger and see if it resolves this issue.

So what causing the phone to shut down if you use the original charger???? I have a Lumia 920 for about a month and experiencing the periodical shut down for at least 5 times now. Last time was today. Last time as I said because I am going back to my Samsung GS3. Thankfully I have kept it just in case :-) As I did the soft reset my battery is 100% so did not shut down because of lack of power in the battery.

nah, that's not it. I'm using the original charger and it still happens. Plus, the phone also shuts down when not on the charger - I doubt that it'll memorize what charger was used and then shut down because of that.

This is really annoying. I had this problem for a while and then send the device to Nokia support. They found some issue with the device and send me a replacement device which was in mint condition. This new device has the same issue.

Its not even 24 hours of using this new device and the phone experienced this issue. I kept the phone down after using it for a bit, the battery was at about 90%; after picking up the phone again for use in less than 2 mins I found the phone is dead. It won't power on.

Having gone through this issue on the previous device, I soft reset it by pressing power key and volume down for 10 seconds.

This is extremely annoying. I am on at&t fyi, I use wireless and wired charging fyi.
