@tobiasgrau0 , can you test with APKs here: https://github.com/opengisch/QField/pull/5359 -- are you still able to replicate?

tobiasgrau0 commented 5 months ago

@nirvn : i have tested it with the APK 5359 unfortunately the problem is not solved

I have the same problem. The stylus works fine until you pan the map and then stops functioning

I can also confirm the problem in the latest QField version (3.4.3 - Ebo 412c8d).

I even updated/ upgraded to the latest hardware (Samsung Galaxy Tab Active 5 5G) and operating system (Android 14, One UI 6.1) to make sure that my ongoing problems with stylus use (unfortunately not just the issue described here) are not due to the outdated base.

Regarding the issue discussed here: I found out that you can get the stylus to work again quite reliably by tapping the burger menu (three dashes at the top left) once. If you then tap back on the map canvas, the stylus works again as intended. The procedure also works during a digitizing process.

Maybe this can be a hint for bugfixing, @nirvn?
