Button on the Mi Smart Projector not working properly.

If the buttons on the Mi Smart Projector cannot work properly, please refer to the following troubleshooting steps:
1. Please turn off the projector, unplug it from the power source, wait for a few minutes, and then plug it back in. Power it on and check if the buttons are responsive;
2. To ensure that there are no physical obstructions, please rub the dust, and debris on the surface of the buttons as this can sometimes interfere with button operation;
3. Ensure that your projector has the latest software updates installed by going to [Settings] >> [Device Preferences] >> [About] >> [System update] and check for updates;
4. As a last resort, consider performing a factory reset on your projector by going to [Settings] >> [Device Preferences] >> [Reset]. This will erase all the data on your projector, so make sure to back up important data before proceeding;
5. If the above troubleshooting methods still can’t resolve the issue, please contact our local official service center or your seller for further assistance. They will help you in this regard.
