If you have only 2 launchers installed and the stock launcher is already set as default, you can't choose when press home on remote. Try install another 3rd party launcher. This will reset the default settings. Press home you should be able to choose which to run and choose only run once not always. Later you can uninstall the 3rd launcher and leave 2, the stock and your preferred launcher. Always remember not to set either launcher as "always".

Read post #430 on previous page .. too many of them.
Personally I like ATV launcher.
Simple TV launcher is good if lazy to choose which launcher to run every time. Just set it as default launcher. Press back on remote twice to get to unifi tv stock launcher and home button to get back on simple tv launcher.

Yes! Me too, but alternatively, install Smart Yourtube TV works well.
