since monday I have an Lumia 920 and everything was running fine. But since Tuesday night I can't open apps sporadically.
This means, after I restartet the Lumia, WP8 and all apps are performing great, but after some time, some apps won't start anymore. This happens to apps from the store, but also to apps like Music, XBox, or just the Settings.
When that problem occurs, the app seems to start, but then the screen stays black and the phone returns to the last opened app. Sometimes it Shows Loading... ord Resuming...
Don't know where this problem Comes from. I already have done a complete phone reset.
Do you have some ideas or perhaps the same problem?
thanks for your answer. I have already done this. Nothing changed.
It seems that it has to do with WiFi or Bluetooth. Have disabled both and the Problems are gone. I will test this for a few more hours... than I will turn on WiFi or Bluetooth again and we will see what happens.
figrured out something new.
If the Problem occurs, only apps delivered with Windows Phone 8 are crashing.
The apps I installed from store are working just fine and apps like Calender, Mail, Alarms, Setting, etc. crashing.
I have the same issue with a Nokia 822. The exact same symptoms you are having. I've factory reset it and absolutely done nothing after that, no accounts linked, wifi, nothing. Some apps simply refuse to work after a few minutes. I don't even have to use the phone, just letting it sit there for ten minutes and coming back to it I can't even get the Settings to work. Same issue with a black screen then the phone going back to whatever screen it was, it looks like an app crash but not sure.
I'm going to be taking this phone back to Verizon is about the only thing I can think of at this point. Maybe it's bad hardware? I'm glad to see I'm not the only one with the issue though.
I tried to change the SIM ans also tried another carrier. Nothing changed. At the Moment the Problem occurs not as fast as before, but its still there.
Already called the reseller, I will get a new phone if some new will arrive at the reseller. Perhaps, next Saturday. :(
I tried the SIM too, it doesn't work. We thought it had fixed it but within a few minutes it was back to this. We're going to just exchange the phone, which is what I should have done today instead of thinking the SIM would fix it.
