STEPS TO REPRODUCE: 1. Make a call 2. Take the phone to the ear The phone automatically turns off because of the proximity sensor 4. Pick the phone back up to look at the screen EXPECTED RESULTS: The screen should automatically turn back on, so that the user can chose to end the call, conference call, or dial numbers. ACTUAL RESULTS: The screen remains turned off until the volume or power buttons are pressed. Please let me know if there is any information I could provide to help with the investigation and troubleshooting of this issue. Thanks!!
Ralph - Can you indicate what build ID you used to reproduce the bug? You can find the build ID in settings --> device information.

I get the feeling that this is a vendor issue, so over to Vendcom.
Component: Gaia → Vendcom

I'll add qawanted here though to see if we can reproduce this on the latest 1.3 build for Open C.

Able to repro on the latest Open C 1.3 base build. Attaching logcat logs. Build ID: 20140505052400 Firmware version: P821A10V1.0.0B06_LOG_DL

Same problem in europe Zte Open C version BUILD FFOS_EU_EBAY_OPENCV1.0.0B04 I am not shure that proximity senso is present.....
Hey Vance, does the Open C have a proximity sensor? Or a light sensor? Or are they hitting a time out?

Proximity sensor (if present in an Open C) is not deactivating the screen during a call. I've tested all the base images that are available to us. I did see that the screen can timeout during a call confirming Comment 7, which could be what was observed in Comment 0 since this enables the lockscreen and that does not deactivate after removing device from your ear. Base Images tested: P821A10v1.0.0B06_LOG_DL_US_EBAY P821A10-ENG_20140401 P821A10-ENG_20140410 P821A10-ENG_20140508

I've just tested this issue on friend's Open C who had encountered the original issue here (the screen doesn't turn on again at the end of a call). His phone received an OTA update just a few days ago and now the problem is reversed: the screen doesn't turn off during a call if he puts the phone close to its ear. This is even more problematic than before because he can accidentally press buttons during a call since the screen is fully on for the whole time.
Been following this topic with interest ... ever since I got my Open C with broken proximity detection ;) I haven't delved deeply enough into my device yet to confirm what I'm about to say, but I think there are two issues here: 1) Sadly, there simply is no proximity sensor on the Open C, or it's widely defective on this phone. 2) The screen-off behaviour is actually timer-based, and has nothing to do with lightness/proximity sensing. The reason I believe #2 is correct, is that the display's behaviour changes depending on the type of call. If you receive an incoming call and answer it, the screen will immediately dim and then switch off after 4-5 seconds. This occurs regardless of anything (your head, hand, a firefox toy, etc) being proximal to the top of the phone's screen. Conversely, if you make an outgoing call which is answered, the screen will never dim or switch off. This concurs with the behaviour observed in comment #10. Because of these factors, and by checking the phone's debug menu (open the dialer and type: *983*0# then hit the green "dial" key) for a sensor - which isn't there - I can only conclude that the Open C does not have one or it's broken. Or, perhaps, a driver isn't installed. There is an older but semi-related issue on Google Groups, here: https://groups.google.com/forum/#!msg/mozilla.dev.b2g/Ly1LWN6SRJ0/8dq1FnBj6NEJ And FWIW, I've been talking to ZTE via their ebay shop and the best they have come back with so far is an offer of financial compensation for the inconvenience. I might be reading between the lines, but this suggests to me that they have no plans to issue an OTA update with a fix.
As I know, Open C comes with 2 different hardware SKU, the eBay Open C doesn't have a P/L sensor, and the one sold in France does come with a P/L sensor. Steve's comment provides a good way to check if your device have a P/L sensor or not. I am now checking with ZTE to see for the eBay Open C(the one w/o P/L sensor), what is the screen on/off mechanism while in-call. Will update here later Thanks

Vance was right. That device has no proximity sensor.
