@albaguirre It might really be the proximity sensor. But in a strange way. Kind of, "it depends on the mood of the device, and when in phone calls it's almost always in a bad mood."
I've noticed this today when my son wanted to find out what the ProximityCheck app is about. I tried to demo it to him, and the sensor switched to "NEAR" (orange) and didn't switch back to "FAR" anymore. I tried again turning the sensor off and on again in the app, and the erroneous behavior remained. I closed the app and tried again, and again it remained orange after moving it to the ear and taking it away again. In another try the app kind of flickered, mostly orange but green inbetween for fractions of a second even with nothing close the phone. Most interesting though, after some time when trying another time the app finally showed normal behavior, with the proximity sensor telling "NEAR" with an object right in front of the phone and "FAR" with the same object further away from it. Very strange. So, is this maybe a hardware defect? In a series of devices of the same model? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to powerd in Ubuntu. https://bugs.launchpad.net/bugs/1493574 Title: [vegeta] Phone app makes screen stay black during call (so you can't hang up) Status in Canonical System Image: Incomplete Status in powerd package in Ubuntu: Confirmed Status in unity-system-compositor package in Ubuntu: Confirmed Bug description: A similar, if not the same bug, has been reported to be fixed for OTA6. This bug report explains that it's no necessary to wait for a minute or so on the phone call, but the screen turns black immediately, and doesn't turn back on again to allow hanging up via a screen control. Potential duplicate: https://bugs.launchpad.net/canonical-devices- system-image/+bug/1483127 Device: Aquaris E5 HD Ubuntu Edition OS version: 15.04 (r5) A) Incoming phone call: - Accept the incoming call by sliding the grey middle button to the green button - Watch the screen turning black - Bring the phone to your ear, speak (as in a normal phone call) - Take the phone away from your ear, note that the screen stays black How to hang up anyway: (workaround) - (continued from above, screen stays black after taking it away from your ear) - Press the screen lock/unlock button (= button above volume control) - Screen with phone app shows for about half a second, then turns black again - Press the screen lock/unlock button again, and try to press the red hangup button quickly - Repeat the previous step until hanging up succeeds B) Outbound phone call: - Open the phone app - Slide up Recent calls list from bottom edge, select a phone number - Press green dial button to initiate the call - Watch the phone dialling and the screen turning black - Bring the phone to your ear, speak (as in a normal phone call) - Take the phone away from your ear, note that the screen stays black How to hang up anyway: (workaround) - (same procedure as in A. above) - Difference in behavior: * In some calls after pressing the lock/unlock button for the first time the screen stays alight (doesn't turn black again after half a second). Jean-Baptiste Lallement confirms on the ubuntu-phone mailing list: In both cases, covering/uncovering the proximity sensor should turn the screen on, if the screen has not been turned off with the power button.
