Preface

As you may know, Yotaphone3 China version by default only allows certain apps in Ink-screen (backscreen). And most of them are reverse-engineered — That means they are not original apps which may have been compromised by the notorious gov.

So I am here to offer how to install any original apps to backscreen.

Enable any apps in backscreen / Ink-screen

Install Yota Launcher and E-ink Launcher

Enable Android Unknown source
Download and install those two apps
Configure E-Ink Launcher and select it as default Launcher
- Open Yota Launcher
- After your first time open Yota Launcher, flip to backscreen and press power button to light it on
- Scroll to E-ink (com.modificator.launcher) and click “设置” (Configure) button
- Press Android Return button of Backscreen
- Hit the Home button of Backscreen
- Select Yota Launcher (and check ‘Do not ask again’)

Install original apps

With 应用宝 – For Chinese

The default “应用宝” is modified and carries potential risks. Uninstall it
Try baidu.com to search “应用宝” and install it.

Or With Google Play Store

Uninstall all native apps via E-ink launcher or 应用宝
- Press any apps shown in E-ink launcher for 3 seconds and remove it
Install new apps via 应用宝 or Google Play
