Lucky I did not read your post before I got my Nokia 920.
The 920 does have a few pesky issues, like slightly poorer reception in rural areas, but have never had the experiences you say.
Being my first smart phone, I listened to friends who had both iPhone and AnDroid, besides being significantly smaller than the 920, they all had lots of complaints.
no issues? Have you not used blutooth with your car? EVERY TIME i get a phone call when/if streaming bluetooth to my MICROSOFT SYNC in the car, it HANGS THE PHONE.
I have updated the Phone. I have updated Sync on the car.
I have found (over the 3 months I have had it) at least 3 different things that hangs it 100% of the time.
Also, the experience (number of touches) to do common tasks is 2-3x iOS or Android.
