Hi there! I see you're having trouble with the Grab app presenting a white screen, no keyboard, and the inability to locate or search for a location on your Android 10 device. Let's work on this together.

First, just to confirm:
- Have you tried restarting the app or your phone already?
- Is your internet connection stable?
- Did this problem start happening recently, or after an app update?

Here’s a step-by-step approach to resolve your issue:

1. Restart the App and Device
Close the Grab app completely (remove it from recent apps) and then reopen it. If that doesn't help, reboot your phone to clear any temporary glitches.

2. Check Internet Connection
Ensure you have a stable internet connection (mobile data or Wi-Fi). Unstable connections can prevent app elements like keyboard and location fetching from loading.

3. Clear App Cache
Sometimes cached data causes loading problems:
- Go to your phone’s Settings > Apps > Grab
- Tap Storage
- Select Clear Cache (don’t clear data yet, so your information remains intact)

4. Enable Compatibility Mode (If available)
Some users with Android have an "Exploit Protection Compatibility Mode" that helps with app crashes and white screens:
- Go to Settings > Apps > Grab
- See if there’s an option for Exploit Protection Compatibility Mode and toggle it on
- Reopen the Grab app

5. Update or Reinstall the App
- Open Google Play Store, search for Grab, and check if an update is available; if yes, update the app.
- If up to date, try uninstalling and reinstalling Grab. This can fix corrupted app files causing the white screen.

6. Check Permissions
Make sure Grab has permission to access location and keyboard input:
- Settings > Apps > Grab > Permissions
- Allow Location and any keyboard/input related permissions.

If after these steps the problem persists, it might be a deeper issue with the app’s compatibility on your device or a server-side issue. In that case, you can reach out directly to Grab support at [email protected] for more detailed assistance.

Would you like me to guide you through any of these steps? Let me know which you've tried, and I can help accordingly!
