Hi! I see you’re getting backup failed notifications from the Proton Drive app on your Android 16 device. Let’s get to the bottom of that together. Could you tell me a bit more about what you’ve noticed? For example:

- Are these notifications appearing during automatic backups or manual ones?
- Do they show any error messages or details about which files failed?
- Have you checked if your Proton Drive storage is full or nearly full?
- Are you backing up photos specifically, or other types of files?
- Have you tried any troubleshooting steps so far?

With a bit more info, I can guide you through some tailored steps to fix this. Meanwhile, some common causes of backup failures include files being open in another app, lack of storage space, or connectivity issues.

Here’s a general approach we can try:

1. Check Storage Space:
Make sure your Proton Drive account still has enough storage available. If it’s full, backup will fail. You can check this in the Proton Drive app settings or the web interface.

2. Close Other Apps:
If the files you’re trying to back up are open in another app (like a photo viewer or editor), try closing those apps and then retry the backup.

3. Toggle Backup Feature:
Turn off the photo or file backup toggle in the Proton Drive app settings, wait a moment, and turn it back on. This can sometimes refresh the sync.

4. Check Internet Connection:
Ensure you’re connected to a stable Wi-Fi or mobile data connection during backup.

5. Restart Device:
A simple restart of your Android device can clear temporary issues interfering with backup.

6. Update the App:
Confirm you have the latest Proton Drive app from the Google Play Store; updates often fix sync and backup bugs.

If after these steps you still see failures, let me know what the notification message says exactly or if there’s a recurring pattern, and we can dive deeper, like checking file permissions or corrupted files that can block backups.

Are you comfortable starting with these steps? Let me know!
