Install RemoteLink on both Android phones — the one you'll control from and the one you'll control. Sign in with the same account on both, and they link automatically.
Android 8.0 or newer · free to start · served from remotelink.app
Tap the download button above on the Android phone. The file saves to your Downloads folder.
When Android asks, allow your browser to install apps from this source. This is the standard step for any direct APK install.
Create your account once, then sign in with it on both phones. Each device shows up in your list automatically — the device owner still approves every connection.
On the phone being controlled, allow screen capture and enable the RemoteLink accessibility service when prompted — that's what makes remote touch possible.
RemoteLink only works with explicit consent on the target device. Every session is approved on-screen by the device owner and can be stopped or revoked at any time.
