Hi there! I understand your PicMa app is frozen on your Android 10 device using WebKit. Let's work through some steps to get you back on track.

First, could you tell me a bit more? For example, when you say the app is stuck, is it not responding at all, or is it just slow? Does it freeze on startup, or after using it for a while?

While you check on that, here are some quick steps to try:

1. Force Close the App:
- Go to your device's Settings > Apps or Apps & notifications > find PicMa in the list.
- Tap Force Stop.
- Then, reopen the app to see if it runs normally.

2. Clear Cache:
- In the same app info screen for PicMa, tap Storage > then Clear Cache.
- Restart the app.

3. Restart Your Device:
- Sometimes a simple reboot can free up resources and clear temporary glitches.

4. Check for Updates:
- Ensure both your Android OS and the PicMa app are up to date via the Google Play Store.

If you have already tried these steps or the problem remains after trying them, let me know, and we can dig deeper—like checking for possible conflicts, device storage issues, or re-installing the app safely.

Does this help so far?
