Since the june update all incoming calls are unknown numbers. This despite the fact that they are from people in my contactlist. I tried looking for settings to adjust but can't find any. Than contacted vodafone and they resetted my network settings. Didn't work. Did a factory reset, no luck. Than did a factory reset and booted the phone. Did not enter any setup en called from other phone. It came in with a full number and not with unknown number. Than did the google setup and all incoming calls went to unknown number again. Did a new reset and installed google with a new account without apps and without contacts. But still unknown number.
To me it seems that the caller id works until the moment I install the google apps.
Anyone here with idea's how to solve? I can't find any similar messages so don't think it is a 8.1 bug.
I will try to find someone with sim from other provider and try it in my phone but that could take a while. I am only one with nanosim in my household.
Disable 4g and Volte, use 3g/2g only. works fine for now.
