Thanks for purchasing AutoHz!

For AutoHz to modify the system's display settings automatically, secure write settings permission has to be granted.

If you're rooted, AutoHz will attempt to do this automatically without a help from a computer. If you're prompted to do this operation manually while you're rooted, please check if you granted root permissions to AutoHz.

• Run adb shell pm grant com.arter97.auto90 android.permission.WRITE_SECURE_SETTINGS

• Go to Android Settings app > About phone and tap Build number multiple times until the developer mode is enabled.

• Go to Android Settings app > System > Developer options, scroll down a page and enable USB debugging option.

• Check here and download ADB for your computer.

• Extract the downloaded zip file.

• Press Windows + R key on your keyboard.

• Type cmd and hit enter.

• Search Terminal from Launchpad and run it.

• Run sudo -s and type your user password. The terminal won't display how much characters you type, it'll remain blank.

• Run export PATH=.:$PATH

Without this, you will get adb: command not found errors.

• From the terminal window, type "cd ". Notice the empty whitespace after the "cd".

• Locate the extracted platform-tools folder from Windows Explorer or Finder(macOS) and drag it over to the terminal window. It'll auto-fill the path.

• Press enter.

• Enter the following to the CMD window, followed by an enter:

adb shell echo success

• You can copy the commands and paste it by right-clicking on the CMD window.

• The command may show an error, this is normal. Your phone will prompt Allow USB debugging for you.

• If it doesn't show an error, skip this step.

• Tap OK.

• Try adb shell echo success again. It must print success.

• Enter the following to the CMD window, followed by an enter:

adb shell pm grant com.arter97.auto90 android.permission.WRITE_SECURE_SETTINGS

Note that it's com.arter97.auto90 and not com.arter97.autohz.

This is because AutoHz was previously named Auto90.

• If the command executed properly, it'll return silently.

• If your device is based on ColorOS (including OnePlus Nord 2), a permission error may occur during the adb command above.

• Please enable Disable permission monitoring from the Android Settings app > System > Developer options and retry the command.

• If you don't need USB debugging, it's a good practice to disable it to avoid potential unwanted access.

• Go to Android Settings app > System > Developer options, scroll down a page and disable USB debugging option.

• Run adb kill-server from the terminal window.

That's it!

You don't have to repeat this process unless you completely uninstall the app and reinstalls it.
