As for Rooted devices, you need to grant permission from the Root permission management app.
NOTE: DO NOT USE one-click root management apps (ie. KingRoot, KingoRoot), otherwise it MAY RISK your device to turn brick or encounter unknown issues. (ie. your device will be recognized as Non-rooted.)
From our customers' experience, it is recommended to use Super SU or Magisk since these are relatively mature solutions online compared with one-click root management apps.
There are 2 WAYS to grant the root permission from the device:
Tips：after upgrading/re-installing, un-checked.
Go to AirDroid Business desktop client > select your rooted online devices (with a battery icon) > click on Remote Control.
Tips: If your rooted device is shown as Offline on AirDroid Business desktop client, please check if Biz Daemon is running on background AND check the internet connection of your rooted devices.
Q: My devices are rooted but it shows the message "Remote Control is unavailable" in Biz Daemon?
A: It means the device does not grant the root permission for Biz Daemon so that you need to manually enable the root permission for Biz Daemon on the root management apps.
Please refer to the following steps:
1. We use Magisk as an example, please open Magisk and tap on the shield icon.
2. After that, please enable Superuser (Root) permission for Biz Daemon.
3. Go back to Biz Daemon > Remote Control > enable Root as the screenshot.
After that, you have granted Root access to the Biz Daemon.
4. Go to AirDroid Business desktop client > select your rooted online devices (with a battery icon) > click on Remote Control.
Special Note: If you do not wish to grant the root permission for Biz Daemon after updating the Magisk app, please tap on the gear icon.
Then, please disable Reauthenticate after upgrade.
