Hi! I understand you're having an issue where the Yahoo News app crashes on your Samsung phone and the screen goes into a black and white error mode. I'd like to help get this sorted.

To start, can you tell me if this happens only with the Yahoo News app or with other apps as well? Also, does the black and white error mode stay on your whole phone's screen, or is it just when the app crashes?

In the meantime, here’s a general approach we can try step-by-step:

1. Restart your phone: Sometimes a quick reboot resolves temporary glitches.
2. Check for app and system updates: Ensure both your Yahoo News app and Samsung phone’s Android system are updated to the latest versions. Updates often fix bugs causing crashes.
3. Clear the app’s cache and data: This removes potentially corrupted temporary files. Go to Settings > Apps > Yahoo News > Storage > Clear Cache and then Clear Data. Be aware clearing data may reset app settings.
4. Force stop and restart the app: Go to Settings > Apps > Yahoo News > Force Stop, then open the app again.
5. Check your Android System WebView version: Since some app crashes are related to Android System WebView, make sure it’s updated or try reverting its updates if the crashes began recently3 10.
6. Look into black and white screen settings: Samsung phones sometimes switch to grayscale (black & white) due to features like Wind Down mode or Color Correction settings. Go to Settings > Accessibility > Visibility enhancements and check if Grayscale or Color inversion is enabled. Also check Digital Wellbeing settings if Wind Down is active4.

Try these steps and let me know what happens. If the problem persists, we can dig deeper!

Are you satisfied with this initial guidance?
