Hi there! I want to make sure I understand your issue clearly: it sounds like the Pacer app is able to detect your gallery photos, but when you try to save your steps data onto those pictures (like as a label or overlay), it’s not saving properly. Is that right?

Could you tell me a bit more about how you’re trying to save the steps to the photos? For example:
- Are you trying to apply step counts as an overlay on photos directly inside the Pacer app?
- Or are you exporting photos from Pacer after walks?
- Are you seeing any error messages when you try to save?

Meanwhile, here’s a quick checklist to try:

1. Check App Permissions: Ensure Pacer has permission to access storage and photos fully on your Android 10 device.
- Go to Settings > Apps > Pacer > Permissions.
- Make sure “Storage” and “Photos and Media” permissions are allowed.

2. Background Running & Battery Optimization: Sometimes Android limits app background activity, which can interfere with saving or updating data.
- Go to Settings > Battery > Battery optimization or Background restrictions.
- Find Pacer and set it to "Not optimized" or allow it to run in the background.

3. App Update & Cache Clear:
- Check the Play Store to ensure Pacer is updated to the latest version.
- Clear cache: Settings > Apps > Pacer > Storage > Clear Cache.

4. Attempt Re-saving: After checking permissions and cache:
- Try re-saving the steps to the photos.

If these don’t help, I may need to know exactly how you are saving the step info to the photos, so we can dig deeper or explore advanced options. Does this sound good? Let me know what you’ve tried or any other details you can share!
