Hi there! I understand you're having trouble with the Zen Color app not working. To help you better, could you please share a bit more? For example, is the app not opening at all, crashing frequently, or showing an error message? Also, did the problem start recently after an update or out of the blue?

Meanwhile, based on recent reports, Zen Color has experienced some issues in 2023, including being disabled on some phones by Google Play due to security concerns. Some users found that Google Play removed the app entirely, which could be why it's not working on your device.

Here are some steps you can try on your Android 10 device:

1. Clear Cache and Data
- Go to Settings > Apps > Zen Color > Storage
- Tap Clear Cache first, then Clear Data
This can fix corrupted temporary files that might cause problems.

2. Check if the App is Disabled
- In Settings > Apps, see if Zen Color is disabled. If yes, enable it.

3. Reset App Preferences
- Go to Settings > Apps > Tap on the menu (three dots) > Reset app preferences
This can re-enable any disabled apps and default settings.

4. Reinstall or Update the App
Since Zen Color was reportedly removed from Google Play, your device might not be able to update or reinstall from there. If you still have the app installed but it’s not functioning properly, reinstalling might not be an option for now.

If these steps don’t help or if the app is no longer available on Google Play for your device, it might be due to recent security actions by Google Play to disable Zen Color temporarily1 4.

Would you be able to try the steps above and let me know what happens? That will help me guide you further.
