Hi, Wayne, Flame(v1.4) doesn't have this problem. * Build information: (Flame - v1.4) - Gaia 9377274b17200a60cebcd2427d489a7756c4cc72 - Gecko https://hg.mozilla.org/releases/mozilla-b2g30_v1_4/rev/24bc2ae19c59 - BuildID 20140805000237 - Version 30.0
Kan-Ru, Is this something you can check?

I guess this was tested on a GPS hardware enabled Dolphin but I still wonder if it's using MLS or not. It might also be that the phone was in deep sleep mode (no wakelocks?) so the apps stopped. Talked to William, he will provide logs on Dolphin.

Here is the log you needed.FYI. (GPS_LOG_20140811_10.log) By the way, I used following steps to reproduce this bug. Steps: 1. Install "Run recorder" app from marketplace, then disable WIFI 2. Launch "Run recorder" app then use it to record GPS data 3. Press power-on button to turn off screen 4. Press power-on button again to turn on screen

From the log, this phone is indeed using the GPS but can't use AGPS because no network connection: D/SUPL ( 1099): supl_serverConnect: getaddrinfo error, error string: No address associated with hostname D/SUPL ( 1099): supl_createTlsConn: supl_serverConnect error I think this is tested in-door so maybe it's just the phone can't get any GPS lock in time. William, could you turn on gps debug logging from developer settings and test again near the window? And run adb logcat with '-v time' so the time information is included.
Thanks Kan-Ru! After I discussed this bug with you, I re-builded a local build then re-tested this case with GPS log enabled. Weird! I cannot reproduce this bug. I also tested this bug on latest PVT build. GPS works as normal after turning off display. * Build information: - Gaia fda0319ff8c10e54faa7f0eaec256402044209b5 - Gecko https://hg.mozilla.org/releases/mozilla-b2g30_v1_4/rev/3a67a0568412 - BuildID 20140812000205 - Version 30.0 So, I doubt that it might have something wrong on the PVT build I tested (20140724000201) I would like to close this bug. Mark it as "WORKFORME". Have a nice day!
