My phone froze again today after 9 days of up time. Interestingly I got the HERE updates just after I did the usual two finger reset followed by time setting etc. I'm hoping that the Nokia Drive beta can now be controlled from my Fiscon BT hands fee kit. Let's see. There is no way that I am sending my phone for repair unless it dies completely or there is a published solution to this problem. Phones are churned out of the factory in hundreds of thousands. There may be some component changes and even setting up changes from batch to batch but I convinced that nobody at Nokia understands what is happening here, or if they do they are keeping it quiet because they know that if can't be fixed easily. Hopefully you will get a new phone Cloudstrife with a high IMIE 
P.S. I haven't had the Portico update from EE yet. Unless it slipped in under the radar.

I'm sure that the reasons are not only one. After sending the phone twice to Nokia care without any luck tried a systematic approach. In my case was simple to pinpoint the problem, it was Bluetooth or the connection to the car hands free system.
the solution is to turn off and on the 920 after each Bluetooth use. Since I don't use it so often it's a minor inconvenient.
Bluetooth as a possible cause is interesting. I am a heavy BT user. BT headset, BT car kit, BT Nokia 360 speakers etc. I tend to leave BT on most of the time and it routinely connects to my car 2 or 3 times a day.
As my phone rarely freezes during the day, I could try turning BT off at night and then turning the phone off and back on again before putting it on the wireless charger overnight. If I get to 10 days without a freeze it will be a new record for me

I had the opposite issue at the beginning: WiFi worked great, it was the SIM connection to make the phone hang (leaving wifi with no cellular data connection: all worked fine; enabling data connection: the phone hung).
That issue was definitively solved applying the Sim trick (remove sim, turn on the handset, leave it 15 mins with no sim after clicking "ok", turn it off, reinsert the SIM).
Since then I had suffered only sporadic freezings, so to investigate more on the cause, I disabled all the background activities.
It no longer freezed since I installed HERE Maps (through the marketplace, it upgraded Nokia maps to Here maps).
And then yesterday by enabling the automatic backup again. Since I turned it off, it has no longer frozen so far.
This is why I suppose that some background activities can still lead phones to hang.
And however, I think that all the entire thing we're discussing here is due just to more than one software bug, even the Sim thing, and not to faulty components, otherwise it would mean that too many Lumias were produced with bad hardware and I really don't think it's the case.
