Functionality Limitations

In its current implementation, this functionality has several limitations, namely:

• Local servers only. If devices can ping each other via their local IP addresses, remote device control should work correctly.

In a local network where all devices are within the same subnet, remote control should function correctly. If, during usage within the local network, a device is located behind NAT, internet access is required to connect the devices. In this case, STUN servers are used to determine the external IP address (within the same local network if the device is behind NAT). However, if you have your own STUN server, this solution is not required.

Specific Features and Nuances of the Functionality

This section describes specific details and nuances of the functionality to help better understand its operating principles:

1. Holding down the “Home” button on the remote disables “Kiosk” mode;
2. Audio support is available starting from Android 10 and higher;
3. Currently, remote control functionality is available even if the device status in the personal account is "off-line" (i.e., it should not be highlighted in green).
4. The remote control process is partially independent from the client application, which provides certain advantages. For example: if the client application has crashed or does not start, remote control can be used to interact with the device — change system settings or install a new client application build to restore device functionality.
5. If a broadcast does not start on the device, the file manager can be accessed via remote control.
6. For proper operation of this functionality, the user must have root access on the device or the device firmware must be signed by the manufacturer. Most importantly, the network must be configured and access to the remote control microservice on the server must be available.
7. On some devices, the virtual “+” and “-” buttons may not function. This is due to hardware limitations of the device. Volume can be adjusted in the personal account via the broadcast settings or using the physical remote control of the set-top box.
8. When repeatedly pressing a button quickly, the device stores all presses but displays them with a delay. For example, if the user presses the up arrow five times, the device will perform all five actions but with a one-second delay after each step. This behavior is a limitation of Android OS.
9. Some executable files located within the storage can be launched.
