3 Enable "Install Unknown Apps" in Android
Because JaWa Companion is distributed directly as an APK without the Google Play Store, Android requires one-time authorization:

- Select the browser or File Manager you used to download the file (e.g. Chrome or Files).
- Toggle Allow from this source to ON.
- Open

On initial launch, JaWa Companion connects securely to our cPanel licensing backend:
- Enter your assigned account username.
- Tap Validate License.
- The server confirms your license validity and atomically binds your phone's installation UUID.
5 Link WhatsApp via Multi-Device QR Code
Link your account using the verified QR code flow:
- Open WhatsApp on your primary smartphone.
- Tap Settings > Linked Devices > Link a Device.
- Point your camera at the QR code displayed in the JaWa Companion application or the local web dashboard.
- Wait for the Noise protocol handshake to finish. The status badge will switch to Online • Linked.
6 Disable Android Battery Optimization
To prevent aggressive OEM power-saving managers from terminating background REST and WebSocket servers:
- Navigate to Settings > Apps > JaWa Companion > Battery.
- Select Unrestricted (or disable Battery Optimization for JaWa).
- Ensure "Allow background activity" is enabled.
