How do I change the launcher on my onn 4K (Walmart)?

onn 4K (Walmart) runs Google TV, so the HOME button is wired to the stock home screen (com.google.android.apps.tv.launcherx) and no launcher picker ever appears. The fix is the same as on every Google TV device — set your launcher as the real home app over the box's own debugging connection — and this page has the parts that are specific to this device: where its Developer options hide, and what to watch for.

Developer options on onn 4K (Walmart)

1. Open the About screenSettings › System › About, then scroll to “Android TV OS build”.
2. Press OK on the build seven timesThe TV counts down, then says you are a developer. A new “Developer options” item appears in the settings.
3. Turn on debuggingDeveloper options › USB debugging. On Android 11 and newer there is also Wireless debugging with a pairing code; on most boxes Network debugging over port 5555 is the convenient one.

What to watch for on this device: it is a cheap box, and it feels it most in animations. After you set your launcher, the tool's Speed up task (animations off) makes a visible difference on the onn — it is the single change people notice first.

Then: the same three routes as everywhere

From here this device is ordinary Google TV: the free TV Launcher Manager finds it on the network (or over USB in Chrome), lists every launcher it has, sets your pick as HOME and records the undo. By hand, the stock package to disable is com.google.android.apps.tv.launcherx — and pm enable brings it back.

adb shell pm disable-user --user 0 com.google.android.apps.tv.launcherx

adb shell pm enable com.google.android.apps.tv.launcherx
