So I made the switch from Google TV to FLauncher after realizing I was literally not using the Google TV UI for anything except launching apps, which it is clearly not optimized for. I followed FLauncher's adb instructions to disable Google TV and Android TV launchers, and now FL is the default.
So far it's been pretty nice, but I've noticed an interesting side effect, my CCwGTV feels faster now? Going home and switching apps is definitely faster for me, most likely a combination of being taken directly to a grid of apps, and no longer loading a bunch of content recommendations and ads whenever going home. But what I didn't expect is that even just using apps like YouTube and others feels smoother and more responsive? Maybe Google TV has a lot of background overhead I hadn't considered? I don't have any way to measure this, but I was interested if anybody else made the switch and noticed improvements?
I did the same after having enough of the ads showing mildly violent or suggestive content to my 2 and 4 year old before I could rush to start the PBS Kids app.
I have definitely noticed the device is a bit snappier with flauncher. It also broke my YouTube button (which I do actually use), but it was easy to reprogram with a button mapper app.
