A few things to know first.
Clear compatibility details for a smoother first connection.
Will it work with my TV?
Your Android TV or box must support network ADB debugging, with debugging enabled and authorized. Being online alone is not enough. Compatibility varies by model and firmware. Samsung Tizen, LG webOS and Apple TV are not supported.
Is NATNT Assistant free?
All current features are free. There is no account, advertising, membership or subscription. The website focuses on downloads and practical guides.
Can phone casting include sound?
Yes. On Android 10+, both full-screen and single-app casting can share audio when the playing app permits capture. Single-app selection limits only the picture: other apps may be audible, so pause other playback. The microphone is not captured. Protected content may be black or silent.
How is phone casting different from TV mirroring?
Phone casting sends your phone screen to the TV. TV mirroring displays your TV on your phone. TV mirroring and recording each have a 3-minute session limit. Live phone casting has no such limit, but depends on the system, network and phone staying unlocked.
Where do I download and update NATNT Assistant?
Choose the Android 0.9.8 APK or Windows 0.9.8 x64 ZIP on NATNT.com. Android updates require the same signer. Quit Windows before extracting a new release. This website is the current official download channel.
Does it support PC, Mac or iPhone?
Official downloads include an Android APK and a Windows 10/11 x64 ZIP. Windows works without a phone. There is currently no macOS, Linux, iPhone or native Windows ARM package.
Can I speak to my TV through my phone microphone?
Phone microphone forwarding is not supported. The voice button opens an available TV assistant or search entry point. Use the microphone on your TV or physical remote.
Why do channel buttons behave differently across apps?
The number pad uses channel up/down on the right; closing it restores page controls. METV (com.metv.tv) gets adapted commands when in the foreground. Other apps receive standard channel keys and must support them to change channels.
Does the speed test measure my phone or TV?
It measures the phone’s current internet connection, not TV speed or local file transfers. Start manually to connect to Cloudflare, using up to about 40 MiB per test. Response time measures HTTPS requests, not Ping.
Can it turn on a powered-off TV?
Wake is only possible while the device is online and debugging access remains available. There is no infrared control. Use a physical remote when the TV is powered off or fully offline.
How do I install or update Windows?
Extract the entire ZIP and run NATNT.exe, keeping companion folders. Quit before updating and extract the new release to a new folder; existing local settings remain available. The EXE is not code-signed. Verify the ZIP SHA-256 on the download page.
