We suspect that the abnormality is caused by the length of infrared signal or infection. Please try the following methods:
1. In activity mode, edit - shutdown settings, find the projector shutdown command, long press and move to the top.
2. You mentioned that the projector can be turned off in device mode. We speculate that it should be controlled by X1 Remote. We also want you to try the power command in the app de command list to see if you can turn off the projector.
3. If X1 Remote can turn off the projector and the app cannot be turned off, this may be caused by the short infrared signal. Please repair as follows:
In device mode, edit -- Projector edit -- macro settings for turn on/off, select turn off, click the power command, and set 0.5s long press for it.
