Android 13 and 14 Samsung Devices - Black screen on RC despite blindly entering PIN

Hi All I can see lots of posts regarding remote control stays black on Android 13 and 14 Samsung devices and generally the advice is to start your RC session, once connected to the device it will show a black screen, use Page Up on your keyboard, followed by the PIN (you won't see it on screen) followed by enter and you will then be able to see the screen. This method works fine for android 12 and 15 devices, but not for android 13 and 14. The android 13 and 14 devices just can't be woken remotely - has anyone got any extra tips or know if an agent is available to support this function. In the past we've just been told this is just the way android 13 and 14 are, but since it is still in support and these are still supported devices (the OS can't be upgraded) then has there been any fixes or workarounds? The test device in question is SM-G780F (max OS is 13) We have Samsung on android 12 and typing the PIN on black screen is fine We have Samsung on android 14 and it has the same issue as android 13 - can't get past the black screen even after typing PIn in blind. We have Samsungs on android 15 and no issues. Any advice appreciated, but please note what I have already tried above and the comparison between android 12 and 15 above. Many Thanks
