My E72 has a Chinese screensaver, but I can't see anything at night!

Of course, if your mobile phone is always on, how much electricity will you use ... then you have to charge it every day. ...

All mobile phones will turn off the background light after a period of time. The reason is simple, saving electricity.

The screen has been on. It must have been out of power for a long time.

On the other hand, if you want to check the time at night, just press the phone and it will light up. Don't watch the lunar solar terms in the middle of the night, watch them tomorrow during the day. ...
