I recently changed out several android TV PCs to TX92 hardware with android 7.1.2. I use them to remote into Windows as a thin client among other things. The last nuisance remaining is the home key. If using Windows and I press the home key on the keyboard, android goes back to the launcher screen. How can I disable this? The units are rooted.


I doubt this is possible.

From Android Developer Center (Google's official site):

Key code constant: Home key.

This key is handled by the framework and is never delivered to applications.

And the Home key on a generic QWERTY keyboard is mapped to the Android "home" button, so it's treated the same as the real home button.

You can try modifying /system/usr/keylayout/qwerty.kl but as per my attempts, it doesn't work. Just in case it would work for you, for what it's worth, I changed

key 102   HOME


key 172   HOME
  • The boxes I replaced had android 4.4.2, I think it was, and there was an option in settings whether the OS should recognize keyboard hotkeys. In many ways they worked better than what I have now with 7.1.2. The processor was just too slow. I waited a long time to swap out. – subjectivist Jan 25 '18 at 23:51
  • This worked! There was a note inside qwerty.kl saying it isn't the default for android any longer, but Generic.kl. I commented out anything saying home, which did not work, but did the same for all files in the folder. Some had a home assignment, some did not. Probably a vendor specific file is being used. For people reading, you must reboot after changing keyboard files for change to take effect. – subjectivist Jan 26 '18 at 0:58
