Dark mode does not persist after app close

[hdlineage]

I'm using LG V30 on android 9. Dark mode works the first time i toggle the option, however after closing the app completely, the app went back to light mode. I have to toggle the option again to get it back to dark mode.

Unfortunately, device specific issues like this are basically impossible for me to debug.

If you can explain what the problem is and suggest a fix, please feel free to reopen.

I actually have this issue as well, on two different devices: my Acer Chromebook Tab10, and my Samsung Galaxy Note 8.0; so it's not a device specific issue.

I manually set the app to use the "Dark" theme, and it works. But every time I close and re-open the app, while the setting itself persists, but the the actual theming doesn't. Changing the setting to "Light" and then back to "Dark" works, but every time I close and re-open the app, it defaults back to light.

Okay, that's interesting. I'll investigate this further.

I've got an update on this issue. My N5120 is running a custom Android 7.1 ROM without native support for system-wide dark mode. I've recently started using the "Dark Mode" app, by Julian Eggers, which seems to trick many apps in to thinking the system-wide dark mode is enabled. Since doing this, VOIP.ms SMS has persiststantly stayed in dark mode.

I tried the same thing on my Chromebook Tab 10 with the same result.
