Features

• Lists the channels the device reports for the 2.4 GHz and 5 GHz bands, with an option to include DFS and disabled ones.
• Stores the selected channel in the hotspot configuration, so the choice survives a reboot.
• Shows the channel currently stored in the hotspot settings.
• Two access methods, Shizuku (no root) and root; the selected one is remembered.
• English and Russian.

Requirements

• Shizuku installed and running, or root.
• Android 12 or newer for Shizuku mode.

Version support

List and apply were checked on emulators: Android 10, 11, 12, 14, 15, 16 and 17. Android 13 was checked on a real device.

If the channel list is missing in Shizuku mode right after a reboot, start the hotspot once — some devices report the hotspot capabilities only after the hotspot has been running. Then press the refresh button next to the current channel.

Methods the app uses:

Channel list

Apply

On Android 10 the channel cannot be applied: the system API for it does not exist, and cmd wifi of that version has neither force-softap-channel nor get-allowed-channel.

How it works

• Channel list — Shizuku mode reads the hotspot capability the system reports (Android 12 and newer), with the framework dump as a second source (Android 13 and newer); on Android 11 it shows the standard list. Root mode uses iw list and the dump.

• Apply — the channel is written into the hotspot configuration, which is what the system hotspot uses:

  getSoftApConfiguration() -> copy with the new channel -> setSoftApConfiguration()
  

• Current channel — read back with the same configuration API.

In Shizuku mode this code runs in a Shizuku user service with shell identity, in root mode in a helper process started with app_process.

Root mode can also apply the channel for the current session only, with the legacy command that Android 12 and newer allow to root alone:

cmd wifi force-softap-channel enabled <frequency>

Install

Download the APK from the Releases page. Builds of 1.0.x are signed with a different key, so the old version has to be uninstalled before installing 1.1.x.

Build

flutter pub get
flutter build apk --release

Release builds are signed with the keystore described in android/key.properties, which is not tracked by Git.

Channel list fixed on Android 11 and 12

Shizuku mode could not read the channel list before this release. cmd wifi get-allowed-channel exists only from Android 14, and the framework dump prints the capability only from Android 13.

The Shizuku user service now registers a soft AP callback and takes the list straight from the system.

• Shizuku mode: channel list on Android 12 and newer.
• Android 11: standard channel list with a warning when the system reports nothing.
• Two sources per mode: system capability and framework dump for Shizuku, iw list and the dump for root.
• Android 10: list only in root mode, applying is not supported.

Verified on Android 10, 11, 12, 14, 15, 16 and 17 emulators, and on an Android 13 device.

APKs: universal, arm64-v8a, armeabi-v7a. Builds of 1.0.x are signed with a different key, so uninstall the old version first.
