App freezes after search

[Schlicki2808]

I'm using uNav under Ubuntu Touch 20.04 and I have the following problem:

1. Starting the app and pressing the "locate" button on the bottom right.
2. When it has GPS, I search for a location by using the search button.
3. I am tapping the found search result.
4. The search page closes, the map appears and the app isn't responding anymore - it freezes.

If I perform the above steps but WITHOUT GPS, the app does NOT freeze. So I search my location, press "navigate" button and then wait for GPS, it works.

This is what I got from the log file:

Hi, thanks for the fast reply. I tried with the following terms: "Wunderino arena" (it finds the stadium in Kiel, Germany) "Lütter Kamp 2" (another street in Germany)

Kind regards

Daniel

Hi, thank you for the feedback! 20.04 was not released yet, then I'll leave this bug open for the future. Best regards!

Behavior: After activate the GPS, coming back from QML (search/setting pages) freezes everything. Click on dark mode (QML) doesn't freeze it.

Different log with GPS enabled:

Where is the issue: https://github.com/costales/unav/blob/migrated-20.04/qml/Settings.qml#L30

[Shauns2]

Is there an update to this issue? I see the same freeze issues with unav.

[cibersheep]

Could it be related to the gps itself? I need to test more but it seamed that gps from the indicator was «freezing» and turned off. I had to reboot the device for it to switch on again

[costales]

The UI should work with GPS or not... I would say is the upgrade of UT OS...

[ruedigerkupper]

I can confirm it happens with pure maps just alike. So this is not specific to the app, it appears GPS (or compass?) access triggers it.
