Symptoms
- Some screens are dark, others stay light within the same app
- Text is hard to read due to poor contrast in dark mode
- Dark mode doesn't apply at all even though the phone is set to dark
- Colors look inverted incorrectly in places
Likely causes
- CommonApp hasn't fully implemented dark mode across all screensDevelopers sometimes roll out dark mode support gradually, missing some screens.
- CommonApp has its own separate theme setting overriding the phone'sMany apps let you choose light/dark/system independently of the phone-wide setting.
- PossibleOutdated app version without full dark mode supportOlder versions may predate the app's dark mode rollout entirely.
- PossibleCached older interface elementsA stale cache can display old light-mode assets even after an update.
- Less commonSystem-wide theme bug after an OS updateOS updates occasionally introduce temporary theming bugs.
What to do
- Check the app's own settings for a separate light/dark/system theme option.
- Set the app's theme to 'system default' if you want it to match the phone.
- Update the app to the latest version.
- Clear the app's cache in phone settings.
- Restart the phone.
- Toggle the phone's system-wide dark mode off and back on.
- Report inconsistent screens to the app developer if the issue persists after updating.
