        Also happens on Volla Quintus with Morph, unav, etc, on latest 20.04 OTA-9. To reproduce in morph you can go to maps.google.com, tap the location thing once, once it got your location, tap it again. The entire UI freezes, including the tab chooser thing. Freezing a whole browser with multiple tabs is kind of annoying.

        Since this seems to have been broken for more than 2 years now.

        • Is there any phone where it actually works without freezing?
        • Any info on how this can be debugged? On desktop linux I'd start by starting the app with strace and see what call it freezes on. Can that be done on ubuntu touch too?

        If i'm not wrong @AppLee in the Q&A said that he uses uNav, pureMaps without issue. Does it mean that is is a device issue ? ( i do have the issue too on P3a since Focal)

          @lduboeuf Yes, he said it's working for him under noble. But It think he's using a Fairphone 4 or 5.
          I don't think it's a device issue because there are multiple affected devices and under these, there are Mediatek and Qualcomm chipsets.
          But, like @haagch said, it would be nice to know, how to debug this issue to help get this annoying bug fixed.

          BQ Aquaris E4.5 (UT 16.04)

            Just tested on Noble, FP4 with Unav and i have the freeze issue.
            @AppLee do you confirm it is working for you on FP5 ?

              Hi @lduboeuf

              Not sure what the problem is, there might be several...
              I noticed some freezes, but I can overcome them and I managed to have to location updated while walking.
              When freeze occurs it's often after making a search or new navigation or this kind of operation.
              Edit: to be thorough only uNav freezes.

              I don't remember exactly but I think I make my search before asking to locate me.
              Basically there is an order that work ; search the location, then start the navigation, then location activation.

              I'm using a FP5 on Noble and Pure Maps doesn't work on Noble yet.

                That was the way I thought it would work reliable, but also this order freezes sometimes.
                When you first locate your position and then try to do something else (e.g. search a destination, calculate a route ...) the crash is save for about 99,9%.

                Long story short, there's nobody who can say, that the navigation is working for him like expected and without issues. And for me, that was the case under Xenial. There have never been any freezes in conjunction with GPS. So, how can we figure out what causes this freezes?

                  On Focal it navigation works fine with Pure Maps, I tested it earlier this year.
                  But since I'm testing Noble, I don't use Focal so much...

                    As long as you don't cancel the navigation uNav will work (and it has been all this time).
                    If you cancel, then close and reopen uNav.

                    With gps, wifi, mobile network all on
                    Tap on the map
                    Start navigation

                      Getting just a bit more into UT, I guess I could get gdb on it, either by just finding a static gdb build and putting it in the user dir, or by making the system writable and installing it, and then attaching to the hanging process, but for the moment I'm just looking around.

                      uNav is really a QtWebEngineProcess and trivially freezing for me.

                      Pure Maps seems to be a native Qt application and it has been very rarely freezing (but it has happened) - on the other hand I'm not sure it ever actually stops locating with GPS while running, so it's hard to say if it suffers the same issue or not - What I'm wondering is if this is just a QtWebEngine issue or a general issue.

                        Not sure if relevant, but I've reported some time ago tha PureMaps freezes for me unless I rebuild PureMaps without AppArmor confinement: https://github.com/rinigus/pure-maps/issues/619

                        I just use OSMand via Waydroyd. UBPorts is less and less usable for me.

                          @Talkless same here, when i need navigation, i use osmand+

                          unav and puremaps are not usable, issues with missing gps signal in app (but other apps in same time can show my location), crashing or freezing and after some application switching
