It is possible to use the home screen APP in two modes.

Personally, I like the second method 1. Dial command method (1) Enter "*#*#9738#*#*" on the dial pad.

(2) Click "Mirror Mode" (3) Click to start "Mirror", the color screen will be black; (This method can also be done by installing more shortcuts software (please Baidu). After installation, add a small tool to the desktop, and select

more shortcuts, then "Activity", find the engineering mode, click and select "Engineering Mode MirrorAcitivity" in the pop-up option) 2. Use two software to solve this problem (1) Download and install the software Download and install YOTA on the main screen

.Launcher and yota3_E-Ink-Launcher_0.1.3 two software.

, if the installation of yota3_E-Ink-Launcher_0.1.3 appears, please try to uninstall the Xinhua News Agency software, because installing this software actually replaces the link interface of the Xinhua News Agency software.

(2) Set the default electronic screen desktop. First run YOTA.Launcher and select E-Ink-Launcher.

Press the home button on the e-ink screen to select YOTA.Launcher and check the default value to avoid being reminded every time.

Click the settings button to bring up the desktop settings menu, where you can set the number of icons displayed on each screen, font size, hiding dividing lines, batch hiding of applications and other functions. Long press the desktop icon to hide and uninstall applications individually.
