Hi there! I see you're having trouble with the HiWaifu app not working. To help you better, can you tell me a bit more about the problem? For example, are you unable to open the app at all, do you get an error message, or is the app not responding when you try to chat? Also, are you using WiFi or mobile data when this happens?

Meanwhile, here are some initial troubleshooting steps we can try that usually resolve common issues on Android 10 devices with WebKit browsers or apps:

1. Restart your device: This can clear temporary glitches.
2. Toggle your internet connection: Switch between WiFi and mobile data, or try reconnecting to your network.
3. Clear the app cache: On Android, go to Settings > Apps > HiWaifu > Storage > Clear Cache. This removes temporary files without deleting your data.
4. Make sure your app is updated: Visit the Google Play Store and check for any updates for HiWaifu.
5. Restart your WiFi router if you are on WiFi.

If you have already tried some or all of these, please let me know which ones, and we can explore more advanced steps like checking for account-related issues or deeper app settings.

Looking forward to your reply!
