If the software is installed on the smart machine, if it is in SIS format, it must be signed and changed to SIXX format, which can be installed directly.

By the way, I personally feel that the extension software has no effect at all, and it is up to me to save electricity or not. Setting up my mobile phone is better than any software. For example, adjust the brightness of the backlight, and the backlight stays on for a long time.
