Tellyscope is a free Android phone app that debloats your Android TV or Google TV over Wi-Fi, no PC and no root

Most smart TVs ship with a second, unrequested TV inside them. Shopping rows, “free” channels, the manufacturer’s own store, and services that wake up whenever they feel like it and eat the memory a cheap streaming box doesn’t have.

The usual cure is ADB, Android’s developer bridge, which means a laptop, a USB cable or an IP address, and a list of package names copied out of a forum thread you hope wasn’t written for a different model. Tellyscope moves the whole job to your phone. In the developer’s words: “Debloat your Android TV, install apps, and browse and transfer files on it, all from your phone. No root, no PC.”

Setup is the one bit of ritual left. You press OK on the TV’s Build number seven times to unlock developer options, turn on USB debugging plus network or wireless debugging, and approve the phone’s key on the TV. The phone has to run Android 8.0 or newer and sit on the same Wi-Fi.

The debloat lists come from cleanyourtv, a project with about 44,800 GitHub stars that bills itself as a way to get “an Apple TV-style home” on any Android or Google TV. Tellyscope matches your set to “one of 330+ tested lists” and “shows every app it will turn off before it does.”

The part I’d trust is what it refuses to do. Built-in apps get pm disable-user, which hides and stops them, and the README says Tellyscope “never runs pm uninstall --user 0,” the harsher command a lot of debloat scripts reach for. Before its first change on a TV, it notes which apps were already off, so “Restore everything turns back on only what Tellyscope turned off.”

It also keeps a protected list. Apps the TV needs “to boot, update, stay on Wi-Fi, show web pages, show its home screen or take input can’t be stopped or disabled, with no override.” That’s the difference between cleaning out the garage and pulling out the water heater because it was taking up space.

Debloating is only half of it. Tellyscope will also set a different home-screen launcher (Projectivy, AT4K, Dispatch or FLauncher), turn on ad blocking through the TV’s Private DNS setting, act as a remote, and send files or APKs from your phone to the TV. The developer says there are “No ads, tracking or accounts.” The only internet requests fetch the debloat lists from GitHub and check for a new version every 30 minutes, which you can switch off.

The caveats are in the README too. Shield and Fire TV “haven’t been tested on real hardware yet,” so owners of those are the early testers. The project is about a week old, licensed GPL-3.0, and the APK for version 0.12.0 is about 2.7 MB. The name comes from Wallace & Gromit’s 2002 short The Tellyscope, in which Wallace builds a contraption so he can change the channel without leaving his armchair.

The open question is how long TV makers keep tolerating this, now that turning off their shopping rows no longer takes a laptop.
