OTA-11: GPS seems not working

[Vincas Dargis]

Just updated Aquaris E5 to OTA-11 (using settings app, no flashing), and noticed that slider to enable GPS device is missing. I am not sure if it was designed so, but GPS does seems like not working. Location service is enabled (at least it seems so).

There are Wireless Wi-Fi and Bluetoof sliders, but no GPS one.

Location service is enabled, but SensorStatus, HERE app does not seem receive GPS info.

By the way, there is no such thing as "/var/log/ubuntu-location-service*" as stated in https://wiki.ubuntu.com/Process/Merges/TestPlan/location-service#Forensics

Attached tar with some logs.

I can see something interesting in logcat output:
E/gps_mt3326( 4545): gps_state_thread: line = 1943error while reading from gps daemon socket: Success: 0xb4fcd294

I've left Location enabled for two days now, and visible_space_vehicles is not empty actually, but it's full of zeroes....

Status changed to 'Confirmed' because the bug affects multiple users.

Same issue with OTA-12.

Attaching logcat output. There are some interesting lines, such as:

D/gps_mt3326( 3334): nmea_reader_parse: line = 1247GPS get accuracy failed, fix mode:1

D/mnl_linux(10399): mtk_gps_sys_gps_mnl_callback: MTK_GPS_MSG_FIX_READY,GET_RTC_FAIL

D/gps_mt3326( 3334): mt3326_gps_start: line = 2188no EPOHAL file, the EPO.DAT is not exsited, or is the latest one

With OTA-11 at least where was some space vehicles visible, now completely zero after ~24h keeping location on.

I am thinking about reflashing, but maybe it would be actually better to try to find actual issue and fix it...

Hi Vincas! The GPS switch has been intentionally removed from the location indicator, and can be now found in System Settings -> Security and Privacy -> Location.

Unfortunately I don't have the knowledge to tell whether the suspicious log messages you copied are indicating an error or not. Anyway, the seem to be coming from the GPS driver, and we have no control over it, AFAIK.

I'll try on my phone and see if I do get similar messages.

Well, I've been on some trip with my car, and... it worked.

Maybe sometimes it just has hard time acquiring satellites, harder when we (users) assumes it should have.

I am not sure about other 6 people who confirmed this bug, but it looks like GPS is actually working for me.

One simply has to have app (SensorStatus or uNav) in the foreground for some time to actually acquire GPS fix. Having Location on for few days does nothing, if you check Sensors app just for short moments through that time.
