    @Stuart-Greer I had the same issue, but somehow I now don't have the issue anymore. Yesterday I re-downloaded the A-GPS data with the app "GPS Status & Control toolbox" or something like that. And today I wiped the cache from the recovery bootloader.

    Note sure what triggered the fix, but somehow my positional error is now only a few meters. Need to do some tests but as far as I've seen today during the test rides, it's fixed for me.

    @StefanHummelink I really hope we get some reproducible results 🙂 The issue is very weird for some Android phones

      @Corjan-Meijerink Tomorrow I'll do some standalone Beta tests, in contrast to the ones today. Perhaps that makes a difference. Hmmm

        @Corjan-Meijerink @Stuart-Greer I have found some very interesting results.

        If I run the MRA app stand-alone I get a delay on the cursor of about 20m while doing 30km/h and about 100m/150m while doing 80km/h. That comes down to a delay of approximately 3 to 5 seconds.

        Now here comes the interesting result: If I run the MRA app in conjunction with another GPS demanding app, such as FlitsMeister or GoogleMaps, the position of the cursor is almost spot on!

        During a ride, switching FlitsMeister on-and off, consistently toggles the delay to be present or not... Somehow, at least on my OnePlus 6, there seems to be a correlation between other apps requesting GPS data as well.

        @Stuart-Greer Can you try to confirm this behaviour? Open FlitsMeister and leave it running in the background, then start a route using MRA Navigation (Next) in the currently launched MyRoute-App Mobile app. Then switch off or swipe away the FlitsMeister app and proceed with the route. Notice any difference in position delay?

        Please post your findings here!

          @StefanHummelink thanks Stefan, the time lag you mention is spot on and something I have timed on the bike and also in the car using android auto. When I mentioned 120m it was at 100lm/hr.
          I will try it alongside google maps and get back to you.
          The app is really good and getting better all the time

            @Stuart-Greer Great, I am very curious!

            If you're phone supports split screen, you could really run the apps in parallel. Perhaps make a screen recording to see whether the track line in relation to the cursor changes. In my case I can observe a very distinct change when it comes to the track line relative to the cursor. 😃

              Hi @StefanHummelink @Stuart-Greer I have been using Flitsmeister in the background previously when running the MRA app on Android and I thought I would check your observations about improved position and less lag. I was running the iOS version alongside on CatPlay to compare and it does appear to significantly improve the lag issue. Whereas I had previously observed about a 4 second lag, the location appears to be spot on and the same compared with iOS when Flitsmeister is running in the background.

              Useful to get @Corjan-Meijerink view on this.

              Kind Regards. Help where I can.

                This is all very interesting indeed!
                My testing device for Android has no other apps installed that use location services - only MRA.
                My positioning is spot on like with iOS or your observation with another app running.

                We will definitely use these findings to further investigate 🙂

                  I'm happy to see the observations by you are identical. That makes two of us and it means I am not a loner hahah!

                      @StefanHummelink hi Stephan, as per your suggestion I ran both apps in split screen this morning on a run into Glasgow City centre and it was perfect. I had it zoomed in to the max and it was as good as any sat nav.
                      Thanks for your help

                          @StefanHummelink @Stuart-Greer Just done some more testing this morning and you really notice the difference and lag (especially when turning) after Flitsmeister running in the background is closed. Turned Flitsmeister off and on multiple times during a route to double check what we are seeing. Really strange but with Flitsmeister on in the background, the position is spot on and direction changes quick.
