If you have recorded item data on your mobile device but it is not being displayed, there could be several possible reasons for this issue. Here are a few troubleshooting steps you can try:

1. Check your device's storage: Make sure that your device has enough storage space to save the recorded data. If your device's storage is full, it may not be able to save new data.

2. Check the app's settings: If you recorded the data using a specific app, check the app's settings to make sure that the recorded data is set to display. Sometimes, apps have options to hide certain types of data by default.

3. Check the file format: Depending on the file format of the recorded data, your mobile device may not be able to display it. Make sure that the recorded data is in a format that your device can read.

4. Restart your device: Sometimes, simply restarting your mobile phone device can resolve issues with displaying data.

If none of these steps resolve the issue, you may need to provide more specific details about the type of item data you are referring to and the app or method you used to record it in order to get more targeted assistance.
