Hi there! I understand your WalkFit app starts up fine but then shuts down after about a minute. Let’s get this sorted out for you. To help me better assist you, could you please tell me:

1. Does the app crash immediately after starting a walk, or during any specific activity?
2. Have you noticed if it shows any error messages when it closes?
3. Have you updated the app to the latest version recently?
4. Is your device running any battery saver or memory management apps that might stop WalkFit?

In the meantime, here are some initial steps you can try on your Android 10 device with WebKit browser:

1. Restart your device: Sometimes a simple reboot can clear temporary glitches.
2. Clear app cache and data:
- Go to Settings > Apps > WalkFit > Storage.
- Tap on "Clear Cache" first, then "Clear Data" (note this may reset app settings).
3. Check app permissions:
- Ensure WalkFit has permission to access your location, sensors, and background activity.
4. Disable battery optimization for WalkFit:
- Go to Settings > Battery > Battery Optimization > Find WalkFit and set it to "Don't optimize".

After trying those, please open the app again and observe if it still shuts down after a minute. If the issue persists, we can try reinstalling the app or checking if there is an update addressing any current bugs.

Let me know how it goes or if you have tried any of these steps already!
