How to setup Zello on Android 6.0 or higher
Android 6.0 has a new mode that will save battery but prevent Zello from working in the background after some time. To disable this mode follow the steps below:
1. Open Android settings and select Battery.
2. Open the options for Battery and select Battery optimization.
3. Select “All Apps” and once you find Zello and/or ZelloWork, change its settings to “Don’t optimize.” This will allow Zello to work in the background.
