If everything appears blank after updating the screen protector cutting machine, the app may not be loading phone models correctly because of incorrect language settings or an app data issue. Follow the instruction video to clear the app’s stored data and reinstall it. On the first launch after reinstalling, connect the device to stable Wi-Fi and wait until the update is fully complete before operating the machine.
What the blank display may indicate
This guidance applies when the screen protector cutting machine fails to load phone models correctly after an update. The documented possible causes are incorrect language settings or problems with the app’s stored data. The available guidance does not identify which cause applies in each case, so the supported recovery action is to clear the stored data and reinstall the app as shown in the instruction video.
Actions to restore the phone models
The first launch after reinstalling is important because the device needs a stable Wi-Fi connection while the update finishes. Use the following supported actions:
- Follow the instruction video to clear the app’s stored data.
- Reinstall the app according to the same instruction video.
- Connect the device to a stable Wi-Fi network during the first launch after the update.
- Wait until the update is complete before operating the screen protector cutting machine.
Do not begin operating the machine while the update is still in progress. Allowing the update to finish is part of the documented recovery guidance for phone models that do not load correctly.
If the models still do not load
After clearing the stored data, reinstalling the app, and completing the first launch on stable Wi-Fi, check whether the phone models load correctly. If the display remains blank or the models are still unavailable, contact technical support through WhatsApp for further assistance. No additional fault-specific recovery steps are documented in the available guidance.
