I did some testing. I am seeing two different behaviors: 1) "Normal" behavior: when the phone is locked/unlocked, the viewfinder shows black for ~1 second and then switches back to live viewfinder mode. This is expected, as the camera-app has to release the camera backend when it becomes inactive (either from moving to the background or locking the phone) such that other apps using the camera will have it available. Only one client connection at a time is allowed and this how Android subsystem we are using is designed.
2) Abnormal behavior: hard to reproduce, but sometimes after lock/unlock the viewfinder shows a frozen image of the previous preview for ~5seconds, then switches to black screen, then to a live viewfinder. Cannot always reproduce this but assuming this is the bug that has been reported. @victor Can you confirm that 2) is the case that is being reported? ** Changed in: camera-app Status: New => In Progress ** Also affects: qtubuntu-camera (Ubuntu) Importance: Undecided Status: New ** Also affects: qtubuntu-camera (Ubuntu RTM) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to camera-app in Ubuntu. https://bugs.launchpad.net/bugs/1398436 Title: Preview frozen after unlocking Status in Camera App: In Progress Status in the base for Ubuntu mobile products: Confirmed Status in camera-app package in Ubuntu: Confirmed Status in qtubuntu-camera package in Ubuntu: New Status in camera-app package in Ubuntu RTM: New Status in qtubuntu-camera package in Ubuntu RTM: New Bug description: [Procedures] 1 open the camera app 2 lock screen on the camera view interface by pressing power button 2.unlock the screen [Expect results] camera screen display normally [Actual results] The preview image is frozen for about 5 secs [Reproduce] May need to do 5 to 10 times Once in this state it seems to then happen consistently To manage notifications about this bug go to: https://bugs.launchpad.net/camera-app/+bug/1398436/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
