SOLVED uNav GPS not working
@JimmyPesto In my experience, search with uNav lack flexibility.
If your input is correct and how the system expect it then it's fine. PureMaps is easier to use on this aspect and the suggestions are quite fast (or I'm a slow writer).
I use PureMaps but I never use the voice guidance. I hate when someone give me orders ^^
@AppLee Pure Maps does not give me any suggestions at the moment sadly. It neither finds any German city at all. I don't know whats wrong with it. Even tough I can zoom into cities and streets successfully.
@JimmyPesto Have you searched for UK, Belgian or French cities ?
I'd like to know if your problem is specific to you or about Germany (which I don't think it is) and maybe you can try with english name of those cities Berlin and Paris are easy because it's the same in most languages (latin based)...
Honestly, I find search poor in both apps. Generally I need to manually find the location and then get directions to a pin on the map, for either to work. Both seem too simple, in that if you don't enter the address exactly as it is in the database (1234 E Broadway vs 1234 Broadway E) you get no results or ones from cities around the globe. Lol, I am in Vancouver and I am not driving to Europe today.
I use Photon as search engine.
And it worked fine until a test I just did...
So I guess there could be a problem with Photon right now... OpenCage is working so not an issue on PureMaps, but probably on Photon.
Thanks for your support. It has been a while and I still enjoy my UBports phone.
BUT the main problem still remains with the slow GPS. If im on the go and need some directions I cant wait for 10 minutes and/or reboot the phone until it works. This is a great practice to keep calme though.
Searching streets in Germany works better now. I switched the maps once but I cant tell whats selected right now. It only says "Mapbox (Voreinstellung)" in maps settings menu. But I cant tell if it is selected.
@AppLee how can I see the selected search engine?
I just bought an OnePlus 3T, will the GPS be as slow as with my OP One using UBports?
GPS is not slow, it's normal.
Lack of A-GPS is what you consider being slow.
Do not reboot your phone it doesn't help.
The first fix takes a long time, but then it's faster (if you don't reboot).
In pure maps:
- Tap the magnifying glass icon
- Then tap the mini hamburger menu in the top right corner
- It shows the selected search engine
If you tap on it you'll see more info: default is set to photon for me and there are alternatives (Digitransit and OpenCage)
Mapbox is the default tiles used for the map ; not the search engine

@JimmyPesto Last time I tried on OP3 with uNav it took about 20 secs. Today uNav is blank for me so can't check just now
@AppLee Yea you right, first localization is slow. After this GPS is okay.
What exactly do you mean by "first fix". So after each reboot or power on the phone has to relocate itself for the first time? What about turning GPS off/on in the settings?
Thanks for clarification, I'm using Photon as well, and its suggestions are reasonable.
@Lakotaubp with GPS always enabled and the phone was powered on for some time I guess? 20s sounds great.
What we call GPS fix is the time for a GPS chip to catch enough GPS satellite signals to determine its location.
The first fix is the first time your phone is able to localize itself.
In fact I don't know if turning off the GPS using the settings will have the same effect as turning off the phone ; maybe.
I rarely turn it off because it doesn't use so much power...
I'm used to this from using Android. It gives you the feeling of having control of your data. haha
Maybe I should just keep it enabled all the time.
Thanks for your quick feedback.
On android I don't trust the OS with my location.
But UT doesn't use this information when you don't need it and GPS being passive it's not a threat for me.
@AppLee this is why I said it "gives you the feeling of".
Yea I'm going to keep it enabled. Thanks for your support.
After some time I am still in love with this wonderful OS. It has even got better and better since the last updates and newest apps.
I have GPS enabled ever since @AppLee told me to.
But only a couple of times GPS worked and I was able to navigate using the phone. Since the last months I was not even able to get my position a single time. This is really frustrating as it is the only thing left from enabling me to use this system only without any Android backup phone..
I can lay the phone outside on a table for 20 mins or take a walk for 20 min but I get no GPS position in neither on of the apps available. It would be awesome to find a way so that I could rely on navigation. When I travel and need to find certain place I can not wait for 30 minutes until GPS is working...
test_gpsis printing a lot of information continuously but I do not understand it. Should I post the output here?
Thanks for your support.

No please dont post the output. You can check there if it prints a valid longitude/latitude after some time.
Is your device second-hand? Some devices loose goot contact with the GPS antenna over time, this might need to be readjusted. Ubuntu Touch cannot do much about it, we take the GPS coordinates from the Android service. So its probably a problem with your hardware, sorry too say.
@flohack Thanks for you kind answer, but how should I know what valid/invalid data looks like?
Whats the difference between
*** location callbackand
*** location callbackprovides a latitude, magnitude and an accuracy of 10.000.
Its prints some coordinates. Sometimes the
nmea (nr):rows have some empty fields
,,but not always.

with my 2 N5 it is exactly the same... if I install LineageOS ( https://sourceforge.net/projects/hammerhead-lineageos/files/17.1/ ) both work fine ( only with GPS ) ...
( with Ubuntu ) if it has found the location it goes faster afterwards. But when you restart the device, the whole procedure starts again...
@manjushri thanks for your feedback.
May I ask how long it takes to initially get your location on these devices and where/how you place them to find it?
Are there devices that are known to have a quicker GPS localization?
I love this OS so much and it would be awesome to find a solution I could rely on. Thanks for your help.
I was able to run
test_gpsand see changes in my position while walking outside in less then 5 min.
I start to feel like I have a different problem with my OP1. I do not know if they are related but to sum up:
- rotation does not spin the display (even though lock is disabled) which worked before
- SensorStatus App is not able to access any of the sensors available on my device, some worked before
