Remote View is available from Android 5 and we cannot also use Digital Signage Display. We are looking to manage some Android 4.2 devices and set up these devices as digital signage. The devices are not receiving update from the manufacturer anymore and we are stuck with this OS.
Is there any way to implement these features?
Why don’t you try flashing an Android 5+ OS to the devices? You can start by checking if your device is compatible with the version of the Android you plan to install from http://source.android.com/compatibility/index.html . Then you can try searching for your ROM and boot loading software from XDA developers’ forums. This article might be helpful for you – http://xda-developers.com/how-to-install-custom-rom-android/
Do proceed with caution as the process could break the device if not done properly.
