I’m happy to hear that it’s working for other people!
I’m afraid that the first thing that I did when I got mine was to wipe out the Android partition and reload Win10. I don’t think I even booted into Android on the X16. I have two other Android tablets and I just never use them. It isn’t a firmware issue. You could maybe call it a driver issue. It’s just a config string that is sent to the hardware after the drivers load. I’ve done a little programming for Android, but I’ve never worked with the drivers. I’m almost certain it would be an easy fix for the Android side. That is assuming that the config file is easy to access and not compiled into something else. When you find it, the config string will follow the same format since that’s the only way the chip will accept it.
Pang, what minor tweak would you suggest?
