[Q] Outgoing calls disconnect immediately, then redialed
I've encountered this weird problem on my rooted Nexus 4. Let's say I enter a phone number to call. When I hit the "call" icon,
1) the phone number is called
2) the call (which hasn't yet been established) is disconnected immediately. This happens in a split of a second. I actually shot a video and then played it frame by frame to actually figure out what's happening.
3) and finally the call is made as usual. Everything is normal from this point on.
This happens for every outgoing call. Same thing happens if I choose a number from the contact list to dial.
I tried uninstalling the apps that I was suspicious about but it didn't help. I also booted in safe mode but I could still observe the problem.
I'd really appreciate any help. I'm more than willing to try something to get a log, trace, etc. to help in identifying my problem. I just don't know how to do that.
