GPS not working
-
I've been doing some more testing:
After many reboot and test cycles the TTFF has been improving. Now it is more in the order of 5 to 10 mins.
Occasionally, after reboot it would not get a fix at all (waiting at least 30+ mins), with the only solution being a reboot. Maybe related to the bug mentioned by @rocket2nfinity ?
I also tested getting location this morning, having had a successful fix last night and no reboot in between. It only took 2 mins.
To give some more context: I haven't used the GPS much since my initial testing of this port in August (staying at home and all). At the time it worked well as @Flohack described. Recently I tried it again a few times and it was not working (hence my original post). Now I see that after many attempts it is sort of "warming up" and performing better. This is pure speculation from my part, but I suspect there is some kind of caching that helps the GPS get subsequent first fixes faster. Over time, if not used frequently, this information becomes outdated. Maybe this is why there is such thing as AGPS? (which, as far as I understand, is not available in UT).
Anyway, I don't think there is much more to do here. Maybe we should mark this as "solved". Thanks everyone!
I will keep doing some more tests. I'd be happy to help testing if there are any projects that aim to improve the overall performance of GPS on UT.

@lgtrombetta That is indeed what A-GPS is for.
-
Its still very strange, tested a few occasions now, I usually have only 10secs to fix
-
Mine didn't use to work, but now it's pretty reliable. I once made it connect this summer, no luck since before last week. I changed the battery and kept the GPS open for a while, and suddenly it's working.
Did it learn where to look after randomly finding a signal twice? Did I accidentaly push the antenna back into place when changing the battery somehow? Was there a change on the devel channel that made the difference?
I don't know, but it didn't work at all, and now it does.

@potet There was no change in software I would say. We use the android container for GPS, so we have 0 influence on what it does ^^ and after a reboot it takes longer to get a fix, so try to keep your device running when possible, that should make future locks faster.
Not that when you close an app with location, GPS will stop so it looses track of all satellites. Thats a privacy feature ^^

@flohack It's quick to reconnect even after reboots now, while earlier I could never make it work at all. So there is truly something that has snapped into place the device.
Not much help for those experiencing problems though - sorry I don't have anything more valuable to add based on my experience!

@flohack said in GPS not working:

About that... it can also be an anti-feature, for instance for the purpose of tracking your sport activities. This point has already been raised before, for example here: https://github.com/ubports/ubuntu-touch/issues/1067

@lgtrombetta i am having the same issue reboot does not help wace you found a soultion?? No matter how long i wait it cant find gps
-
@cor3 GPS works for me. There is some sort of hang up that occasionally occurs. Try restarting the UI with UT Tweak tool
-
@rocket2nfinity ill give that a try right now considering ive rebooted and tried everything else ill let you know how it goes
-
@rocket2nfinity well using t ut tweak tool just caused the screen to sit and load i had to hard reboot my phone, just tried with pur maps and still no sucess....ive tried two other map apps also no luck.....

@rocket2nfinity only issues ive had so far since my inital install yesterday is ,1 gps can not and will not find location, bluetooth wont even turn on when i flip the BT switch it goes byby and sometime if i open to many windows the screen locks up but the screen is not a big deal ive figured out to keep a max of about 4 open windows and there seems then to be no issue but the other two problems ugggg really sucks
-
@cor3 You will also find video recording is now broken. My N6P is becoming unusable after being rock steady for a long time. Was going to reflash, but your experience proves that won't help.
The porter is aware of the problem and is working on a solution.
-
@flohack im gonna give that a shot and see if it works ill post later if it works or not thanks for the fyi
-
@rocket2nfinity hope to see some fixes flohackk just messaged meband said to leave it on and wait so im gonna put a movie on and leave my phone plugged up and screen on and see if the gps locks correctly
-
@cor3 Don't know if you have tried it but the sensor status app from the OpenStore will tell you if GPS is working. Getting detected can take a lot longer, 45 mins was my longest on a UT device.
-
@cor3
Also keep the phone outdoor as it won't catch any satellite signal indoor.
Seems obvious for some but worth mentioning. -
@applee your correct it wokks outside got it working yesterday sorry for the late report and ty for the fyi

@lgtrombetta , mine is Meizu MX4. I went to the housetop of a building, open the uNav. Then the GPS works.
