Hello! I’m sorry to hear you can’t play back videos recorded on your SD card using the VicoHome app. To help you better, could you tell me if the videos fail to load inside the app entirely, or if there's an error message when attempting playback? Also, have you tried playing those videos outside the app, like on your phone's gallery or a computer via an SD card reader?

Meanwhile, here’s a step-by-step guide to troubleshoot playback issues on SD card videos with VicoHome:

1. Check Video Access in the App
- Open the VicoHome app.
- Go to the Library page and tap “SD Card” in the top right corner.
- Select your camera and tap “Confirm” to view recordings stored on the card.
This ensures you are accessing the right storage location4.

2. Remove and Reinsert the SD Card
- Power off your camera.
- Carefully remove the SD card, inspect it for damage or dirt, then reinsert it firmly.
- Restart the camera and reopen the app to try again.
This step helps re-establish proper connection and refresh the system’s recognition of the card5.

3. Format the SD Card (if accessible)
- If the app shows an option to format the SD card or your camera interface allows it, try formatting the card after backing up your files.
- Sometimes corrupted or incompatible formatting can cause playback issues.
Be aware this erases all content on the card—do this only if you have copies or don’t need the existing recordings5.

4. Cache Clearing in the App
- Go to the app’s settings: Tap “User/My” > “About App” > “Clear Cache.”
- Restart the app and check if video playback improves.
This removes temporary files that might be causing glitches2.

5. Test Playing Files Outside the App
- Remove the SD card and connect it to a computer or phone using an SD card reader.
- Try opening the video files with a media player.
If videos play fine there, the problem might be with the app rather than the files themselves.

6. Update/Reinstall the VicoHome App
- Check if your app is updated to the latest version.
- If issues persist, uninstall and reinstall the app.
This can fix bugs affecting playback.

If after these steps the videos still won’t play in the app but are accessible via card readers, it may be helpful to check for app-specific bugs or reach out to VicoHome support for deeper assistance.

Could you please let me know where you stand with these suggestions or if you have tried some already? That way I can help you further!
