 Hey guys, I have some wierd behavior on my Phone App. first thing: 
 Every time I call somebody, UI of phone app freeze but the connection works. It's not possible to push any buttons. I have to kill the app by swiping from the right side. If somebody calls me - Phone App works as expected.second thing: 
 The history of called contacts works fine. But, if I push phone button (green button on the bottom). App doesn't open last called number, instead it opens a number I called some month ago.somebody an idea how I can fix it? Hardware: 
 BQ E4.5
 Channel: RCBest regards from Germany!!!

 @ds810 I've moved your question to Support. What OS are you running on your phone? Vivid or xenial? 
- 
 @advocatux 
 OS-Build-Number:
 r15
 Ubuntu 15.04
- 
 HU! r15 is the old Canonical version? Did you ever change to UBports? BR 
- 
 @flohack yes. I switched to UBports ca. 1.5 years ago... I have OpenStore on my phone etc... Do you mean I should install UBports again? 
- 
 @ds810 I think he meant that if you're running "r15" that's Canonical's, not UBports' image 
- 
 @advocatux I understood. But I wouldn't have OpenStore on my phone if it would Cannonical image - right? I also can switch to different release channels like: stable/rc/dev. So far I know it's also an UBports feature. 
- 
 @ds810 if you go to "System Settings > About" What it says in the OS line exactly? 
- 
 @advocatux Ubuntu 15.04 (r15) 
 PS: I have UBports Boot-Logo on my phone...
- 
 @ds810 that's really weird, sounds like a half-cooked installation if that's even possible. You should see "Ubuntu 15.04 (r3)" 
- 
 @advocatux I switched from RC channel back to stable. System Settings -> About shows Ubuntu 15.04 (r3). But the App still freeze.

- 
 @advocatux You are right. Maybe it's better just to reinstall the os.... But I think I'm not alone with this issue: 
 https://github.com/ubports/ubuntu-touch/issues/195
- 
 @ds810 oh, I thought that bug was closed (sorry). Anyway, maybe you should consider to go for xenial because I think 15.04 bugs are not going to be fixed, unless they impact xenial too, of course.
