Important announcement about the app

My development environment was infected by unknown malicious software, as a result of which a few builds may have been affected. Once the issue was detected, I secured everything with a full disk wipe, restored a clean setup, and now all builds are scanned with VirusTotal. The F-Droid version will also be verified before release.

Public keys may have been compromised, which is why I am sharing this issue. You can download the new version and the new public key below, and instructions for restoring backups are provided.

No extra actions are required since the app uses one-time connection codes. These codes have very limited permissions (for example, they cannot change your password). Still, you can revoke them if you want full peace of mind.

How to revoke access:

1. Open myaccount.google.com/security
2. Find “Your connections to third-party apps & services”
3. Tap “See all connection” and locate YouTube TV or Google Drive
4. Select the app → “Remove access”

Please keep built-in security features enabled to stay protected.

Device support

> [!IMPORTANT]
> Starting in October 2025 new Amazon FireTV devices no longer run Android under the hood. SmartTube will not be compatibile with the Fire Stick 4k Select and newer devices which run Amazon's own VegaOS.

• Supported: all Android TVs and TV boxes (incl. All FireTV devices released before Oct. 2025, NVIDIA Shield & Chromecast with Google TV), even older ones with Android 4.3 (Kitkat).
• Not supported: Smartphones, non-Android platforms like Samsung Tizen, LG webOS, Apple TV, etc.

Installation

> video of the installation (note: download url changed to kutt.to/stn_beta or kutt.to/stn_stable)

Do not download SmartTube from any app store, APK websites or blogs; these were uploaded by other people and may contain malware or ads. SmartTube is not officially published on any app store.

There is a beta release (recommended) and a stable release. Beta gets new features and bugfixes faster than the stable release.

You can use either of the following methods to install the app:

• (Easiest) Install Downloader by AFTVnews on your Android TV, open it and enter kutt.to/stn_beta or kutt.to/stn_stable, then read, understand and confirm the security prompts. (You can also enter 79015 (for beta) or 28544 (for stable), but this requires an extra step to install the AFTVnews Downloader browser addon if you haven't already.)
• Install a file transfer app on your Android TV, download the APK on your phone or computer and transfer it to your TV (e.g. _Send Files to TV_ from the Google Play Store / Amazon AppStore)
• Download the APK onto a USB stick, put the USB stick into your TV and use a file manager app from the Google Play Store / Amazon AppStore (e.g. _FX File Explorer_ or _X-plore_). Android's preinstalled file manager does not work! Do not get the ad-infested _FileCommander_.
• If you are an advanced user, you can install it using ADB. guide | alternative guide

Troubleshooting: See device specific notes below. If installation fails, either your disk space is full or the APK file didn't download correctly; clear up space and try downloading again. If the app installed, but crashes when opening, make sure to install it to internal memory, not to an SD card / external storage.

The app has a built-in updater with changelog. You can also find all releases and the changelog on the Telegram channel @SmartTubeNewsEN (readable without account) or on Github.

> latest beta download
>
> latest stable download

Installation (Chromecast with Google TV)

On Chromecast with Google TV, installation of apps is blocked by default, so an extra step is required:

> 4.1. Enable Developer Options
>
> On your Chromecast, open the side menu and go to _Settings > System > About_. Scroll down to the _Android TV OS build_ section and click that repeatedly. A toast message will appear, explaining that you are a few steps away from being a developer. Continue clicking until you trigger it.
>
>
> 4.2. Turn on the "unknown sources" setting
>
> Go back to the main _Settings_ page and select _Apps > Security & Restrictions > Unknown sources_. Turn on the toggle for [_Downloader by AFTVnews_ or] whichever file browser you decided to use [...].
>
> [source & picture guide]

After this, you can follow the general installation guide above.

Installation (Xiaomi devices with Chinese firmware)

Xiaomi's Chinese firmware might block the installation of the beta version. The international firmware is not affected. Solutions:

1. Use SmartTube's stable version instead (recommended)
2. Use the international firmware for your device
3. (if your device is from 2020 or before) You can do a factory reset and then install SmartTube beta before doing any system updates. You can then safely update your system, SmartTube should continue working.

Updating

The app has a built-in updater. You only need to follow the installation procedure once. A few seconds after launching SmartTube, it will notify you if there is any update and also show a changelog. You can disable automatic update checks or manually update in the settings under "about".

If the installation fails, either your disk space is full or the update didn't download correctly; clear up space and try updating again (_Settings > About > Check for updates_).

Compatibility

SmartTube requires Android 4.3 or above. It does not work on non-Android devices (incl. LG or Samsung TVs). On unsupported TVs, you can use a TV stick or TV box. Though this app technically runs on smartphones and tablets, it is not optimized for such and offers no official support!

It has been successfully tested on TVs, TV boxes and TV sticks that are based on Android, including:

• Android TVs & Google TVs (e.g. Philips, Sony)
• Chromecast with Google TV & TVs with _Chromecast built-in_
• Amazon FireTV stick (all generations)
• NVIDIA Shield
• TV boxes running Android (many cheap chinese no-name boxes)
• Xiaomi Mi Box

Features

Interface

SmartTube focuses on a clean and distraction-free interface for watching media content. The app does not include advertising UI elements and focuses on playback and browsing experience instead.

SponsorBlock

SmartTube includes optional SponsorBlock integration. From the SponsorBlock website:

> SponsorBlock is an open-source crowdsourced browser extension and open API for skipping sponsor segments in YouTube videos. [...] the extension automatically skips sponsors it knows about using a privacy preserving query system. It also supports skipping other categories, such as intros, outros and reminders to subscribe [and non-music parts in music videos].

You can select which categories you want to skip in the settings. Unlike the browser addon, in SmartTube you cannot submit new segments (TVs and TV remotes aren't great devices for such precise operations). Note that SponsorBlock is a free and voluntary project based on user submissions, so don't expect it to 100% work every time. Sometimes, sponsor segments are not yet submitted to the database, sometimes the SponsorBlock servers are offline/overloaded.

Casting

To cast videos from your phone (or other devices), you must link that device to your TV. Unlike the original YouTube app, SmartTube does not automatically show up when you are in the same wifi network. How to link your smartphone and TV:

1. open SmartTube and go to settings
2. go to "Remote control" (2nd option)
3. open your YouTube app on your phone, go to settings > General > watch on TV
4. click on _connect using TV-code_ and enter the code from your TV

Screenshot guide

Due to technical limitations, you need to open the app on the TV before casting; SmartTube cannot automatically wake up the TV.

Picture-in-Picture (PiP)

SmartTube supports playing videos in PiP mode. This needs to be enabled under _Settings > General > Background playback > Picture in picture_. The video will go into PiP mode when you press home while playing a video, and also when you press _back_ if enabled in _Settings > General > Background playback (activation)_.

Adjust Speed

You can adjust the playback speed pressing the speed-indicator icon (gauge) in the top row of the player. This is remembered across videos. Some speeds may case frame drops, this is a known issue.

Voice Search

To enable global voice search, an additional app must be installed alongside SmartTube. This _bridge app_ allows the system voice search to open SmartTube instead of the default YouTube app. For this to work, you must uninstall the original YouTube app. We know this sucks, but you can always reinstall it if you change your mind. The _bridge app_ will not show up in your launcher and you cannot launch it directly; it is only used internally by the system's voice search. On some devices, you need to explicitly say "Youtube" when searching (e.g. say "youtube cute cats" instead of just "cute cats").

On Amazon Fire TV:

1. Uninstall the original YouTube app (no root required)
2. Download and install the Amazon Bridge SmartTube app: https://kutt.to/stn_bridge_amazon (e.g. via _Downloader by AFTVnews_)

On Google Chromecast with Google TV:

1. Uninstall the original YouTube app (no root required)
2. Download and install the ATV Bridge SmartTube app: https://kutt.to/stn_bridge_atv (e.g. via _Downloader by AFTVnews_)

On all other Android devices, sadly root is required to enable this:

1. Root your device (search for a guide for your specific device)
2. Uninstall the official YouTube app using root (adb shell pm uninstall com.google.android.youtube.tv)
3. Download and install the ATV Bridge SmartTube app: https://kutt.to/stn_bridge_atv (e.g. via _Downloader by AFTVnews_)

Team

SmartTube is developed single-handedly; there is no larger team or company behind this. This is an open source, hobby project. Several others have helped with translations, some of which can be seen on Github, some have sent their translations directly to Yurii. There are also helpful people in the support chat.

Build

NOTE: OpenJDK 14 or older (!) is required. Newer JDK could cause app crash!
To build and install debug version, run these commands:

git clone https://github.com/yuliskov/SmartTube.git
cd SmartTube
git submodule update --init
adb connect <device_ip_address>
gradlew clean installStstableDebug

Video codecs

Video codecs are the algorithms used for video compression.

Which codec to choose / overview

* Examples taken from the video-only track at 1080p @ 25fps for this video: Dua Lipa - New Rules (Official Music Video)

At the same resolution, a lower bitrate is better! YouTube explicitly targets the same quality regardless of the codec. Older codecs have a higher bitrate only because they are less efficient. On Youtube, you do not get better quality by simply choosing a higher bitrate. Newer codecs have a better compression = lower bitrate = use less bandwidth = save the environment. This is a feature, not a bug. You should use the newest codec that works smoothly on your device, not the least efficient one. AVC usually has the highest bitrate. This is bad, not good.

Which quality to choose?

Currently, there is no automatic mode based on your bandwidth. But you can configure a default video preset yourself under settings > video player > video presets. The first option ("none") will remember your last selection within the video player. Any other preset is used initially for each video; if the selected profile is not available, the next best available option is used. You can still override the profile on each video individually within the player.

To decide the optional resolution / video quality for you, you need to consider a few limiting factors:

• Your bandwidth (choose only up to the bitrate that your bandwidth can handle; you can do a speedtest using fast.com by Netflix)
• Your TV's display resolution (the quality might slightly improve, if you select the next higher resolution, e.g. 1080p on a 720p display; but don't expect a big difference)
• Your TV's capabilities (e.g. HDR, 60fps)

Generally 60fps is an improvement, but if you personally don't notice (or mind) the difference, you can save bandwidth (and the environment) by not choosing 60fps.

HDR

HDR works only if your hardware supports it. It's a complicated mess:

• Your TV must support it
• If you use a TV box, that TV box and your TV cable and the TV must support HDR
• Yes, there truly are different HDMI cable versions with different HDR-support, it's complicated
• some devices (like the NVIDIA Shield) generally support HDR, but not the specific HDR format that is used on YouTube :cry:

If HDR videos look dim or washed out, then check this article. If HDR is not working, it's probably not this app's fault. You might need to search on the web for "HDR" and your device name for any help.

FAQ

Q: Videos buffer a LOT

A: Try to switch to encrypted DNS like NextDNS. You can set-up such DNS either automatically or manually. To automatic set-up you can use the Intra apk at fdroid and the "AutoStart - No root" apk to make it autolaunch after every TV restart. For manual set-up use this guide.

Q: There is no result for the search that I say (Android 11)

A: They're some reports that the latest update for "Google app for Android TV" could cause this bug. Deleting the update should fix the problem.

Q: AV01 does not play / Why is VP9 slow on my device?

A: Because AV01 is very new, most TVs and TV boxes do not offer hardware support and cannot play AV01 at all.

If your device has hardware support for a codec, videos using that codec should play smoothly. High resolutions might also be slow in VP9 on cheap TV boxes that don't officially support 4k. Your device probably can play VP9 videos even without hardware support, however this requires a powerful CPU to run smoothly. Fixing AV01 without hardware support is technically possible, but currently not planned and probably not efficient enough.

Q: Can you make SmartTube look like the original app?

A: Compared to SmartTube's UI, Stock Youtube and YT Kids are far ahead. However, we'd need someone who's skilled and willing to dedicate enough time and energy into making it. And into maintaining it longterm (incl. new features, bug fixes). All of this for free. If you are / got someone like that, please help.
Not to mention that SmartTube follows Google's official template & recommendations for Android TV apps. It's Google's fault that the template is somewhat ugly. 😂

Q: Can the search page be improved?

A: It can be, but it takes someone to do it, similar to the above FAQ-entry. SmartTube is following Google's officially recommended design/template for TV apps and is using the official, preinstalled Android TV keyboard. Sadly, Google did a really bad job regarding the search page and keyboard. Maybe a future SmartTube update can add an embedded keyboard, similar to the original YouTube or other major Android TV apps. Maybe it can improve the looks to be as good or better than in the official YouTube app. But for now, it is the way it is due to lack of time and due to Google's official recommendations being bad.

Q: Can I install this on a Samsung Tizen TV / LG webOS TV / Roku / iOS / toaster?

A: No, this only works on Android devices. If you look at an Android TV's product page, it usually says clearly that it's based on Android. The app cannot easily be ported over to other plattforms and we have no plans to even try. Please do not ask. Instead, you can connect a separate TV stick or TV box to your TV.

Q: Can I install this on a smartphone? / Can you add portrait mode? / Scrolling doesn't work.

A: Big No. This app is not for smartphones, we offer zero support for that.

You can cast videos from your smartphone to a TV / TV box running SmartTube, though. Just use the official YouTube app, Morphe or ReVanced, see the casting section for more information.

There will not be a phone version. You can use Morphe, ReVanced, Pure Tuber, LibreTube, NewPipe, or NewPipe x SponsorBlock instead. Please go to their respective support chats for help.

Q: Can I install this on a tablet / car screen / smartphone with docking station?

Yes... maybe.. Requirements:

• It is an Android device
• It has a large screen
• It has a TV remote, controller, or keyboard

Touch input is not supported. Mouse/touchpad scrolling neither. You cannot properly use SmartTube with only touch or mouse input.

Some users reported great success (incl. on a car entertainment system). Please share your success stories with us.

Q: I get "unknown codec" / "can't download video" errors

A: please wait 5 seconds for the video to play. If that doesn't help, press the play button. Some users reported, that this issue only appears when they have a USB audio device attached or if their disk storage is full.

Q: I get "the video profile is not supported"

A. Press the "HQ"-button in the bottom-left, select _video formats_ and select anything other than AV01. AV01 is not supported on most devices (apparently including yours), so select VP9 instead. See the section on video codecs for more information.

Q: I get "video unavailable" when watching unlisted videos / my own videos

A: Right, that's currently a bug.

Q: It doesn't show up on my casting list

A: Please read the Casting section.

Q: I get an error saying "Sign in to confirm you're not a bot"

A: Your IP address range might be temporaily/permanently blocked by YouTube from watching videos if you not signed in to your account.

Q: The video is buffering a lot

A: The issue might not be specific to SmartTube, as other unofficial YouTube apps also report this issue. It seems uncommon nowadays, but was very present in the 2nd quarter of 2021. Some users or devices seem to be more affected then others. The official YouTube app & website are apparently only rarely affected. The root cause of the issue is currently unclear, but it appears to be a server-side thing on YouTube's end. Possibly, YouTube is discriminating 3rd party apps.

For now, try to see if it helps to:

• Reduce the resolution (or chance it back)
• Change the video format to AVC
• Increase the buffer in the settings
• Hit the back button and try playing the video again

Q: The debug information says my display is 1080p, but I have a 4k/UHD display!

A: Do not worry, the debug information is incorrect. SmartTube works fine even above 1080p and you should be able to see that, when you play a video in 4k or UHD.
Also do not worry if it says "720p" and you have a 1080p display.

Q: Why does it not autoselect highest quality?

A: It does (by default). If you set a _video profile_ under settings, that acts as a maximum for automatic selection. Check if you configured a video profile, you can unset it by choosing "none".

Please do not confuse quality with bitrate. See the section on video codecs for more information.

Q: Can I set a (maximum) resolution by default?

A: SmartTube automatically select the highest available quality for your video, up to a maximum resolution that you can set in the settings under "video profile". If available, SmartTube will pick the selected video profile, or otherwise the next best one available will be used. You can still always change the video profile while watching videos.

Q: Can it set the resolution to "auto", depending on my available bandwidth?

A: This is planned, but not available yet (sorry 🙇‍♀️). However, you can set a maximum resolution to something that should work for your bandwidth. See above for details.

Q: Why does it skip video segments?

A: SmartTube has a feature called SponsorBlock. You can select categories should be skipped, if any. See the SponsorBlock section for more details.

Q: How to start the next video automatically / stop after every video?

A: You can switch between different autoplay-modes using the loop-button 🔁

<img src="http://images/new/V3GHGvWprmdE1w.jpg" alt="screenshot showing the loop-button" class="ra0-md-img" loading="lazy" />

Q: How to remove recommended videos (e.g. news) that are unrelated to me?

A: Recommended videos are defined by YouTube and not by the app, we cannot change the algorithm. They are based on your country, which you can change in the settings. If you are logged in, they are based on your watch history, user profile data, and whatever else Google might use. If you are not logged in, you are like in "incognito mode", so your watch history does not influence your recommendations. Maybe a future version will add optional user profiling without logging in.

Q: Does HDR work?

A: Yes, HDR works if your hardware supports it. The NVIDIA Shield does not. See the section on HDR for more information.

Q: Why do some updates say "don't update if satisfied with the current version" in the changelog?

A: These updates change a lot of code, trying to fix bugs that only affect a few users/devices. Only the affected users should update. For anyone else, there is nothing to gain from updating; however there is the chance of causing new bugs. Do not worry if you updated anyways.

Q: When playing at other speeds, frames are skipped!

A: We currently cannot fix this, sorry.

Q: What is AFR?

A: "Auto Frame Rate". It adjusts the refresh rate of your TV to match the content you're watching. It can slightly improve the smoothness, but the difference is very small; most people barely notice it. It does not work well on every hardware. If you don't know what it does and don't want to test it out yourself, you can safely keep it off.

Recommendation: You can turn it on to see if it works on your device; if it causes issues (or if you don't care to test), turn it off.

Q: Should I choose high or low buffer?

A: The higher your buffer, the more of a video will be preloaded ahead of your current position. A low buffer might minimally reduce your bandwidth usage, if you often close videos before they end. A high buffer can smooth out network issues and prevent the video from pausing to buffer. A higher buffer increases RAM usage, however this shouldn't be an issue.

Recommendation: high.

Q: Can I retain the buffer when seeking back?

A: No, when you seek back (e.g. jump back 5 seconds), SmartTube will have to rebuffer. This might be improved in a future update.

Q: My device freezes when watching YouTube

A: That's a firmware or Android issue. If you are using a custom rom, maybe that rom is buggy. Because this issue is nearly impossible for the developer to debug, we cannot help you, sorry. You can try the usual workarounds: rebooting, clearing cache, reinstalling the app, or factory resetting the device.

Q: Can I download videos?

A: Not with SmartTube

Q: Can updates be installed automatically?

A: No, this is technically not possible. Only the preinstalled app manager (usually Google PlayStore, Amazon AppStore, etc) has the required permission. All other apps, incl. SmartTube can only show open installation prompt. A workaround using root would be possible, but hasn't been implemented yet.

Q: Can I whitelist ads on some channels?

A: No, this is not possible. SmartTube does not have any code to display ads. Adding this functionality would actually take time and effort, which is instead spent on adding useful features and fixing bugs.
