Hi there! I’m sorry to hear the update has caused trouble for you. Could you tell me a bit more about what exactly isn’t working? Is the PCH app completely frozen, won’t open, showing errors, or is it affecting the entire device system in some other way? Knowing more will help me guide you to the right fix.

In the meantime, one common fix for app update problems on Android (your Android 10 device with WebKit browser) is to force close the app and clear its cache and data. This often resolves issues caused by corrupted temporary files after an update. Here’s how you can try that:

1. Go to your phone’s Settings.
2. Tap on Apps & notifications (or simply "Apps").
3. Find the PCH app in the list and tap it.
4. Choose Force Stop to close the app completely.
5. Then tap Storage & cache.
6. Tap Clear Cache, then Clear Storage or Clear Data.
7. Restart your phone and open the PCH app again.

If this doesn’t help, we can try checking for any further updates or reinstall the app if necessary.

Did you already attempt these steps, or did you notice if the problem is happening beyond just the PCH app—like your whole phone system acting up?

I’m here to help get this sorted out!
