Resolving the Black UI Issue in Locusview Mobile App

  • Updated

1. Summary

This guide addresses the issue where the Locusview mobile app turns black after launching it for the second time. The first launch displays the normal background, but subsequent launches cause the background to turn black, and some text turns white. This behavior is often due to dark theme styles being applied by the device or a bug in the Android version.

 

2. Why This Issue Occurs

The black background and white text result from dark theme styles being incorrectly applied to the app. This issue specifically occurs on Gen 2 versions 18.3, 20.2, 21.0, 22.0 of the Locusview app when used on Tab Active 3 and Tab Active 5 devices. It can happen either because dark mode is enabled on the device or due to a bug in certain Android versions where the dark theme is applied regardless of settings.
