The CoreNexa Mobile App registers in order to make calls or receive calls. The app will then unregister to save battery life. If you are having issues with calls please make sure you have the latest version of the app installed.
Our infrastructure does not allow multiple registrations for the same user. To resolve this issue, please log out of one of the mobile devices.
Under the Settings menu item, there is an option to “Keep Display Active During Calls”. By enabling this, the screen will not shut down during the call.
Android 6.0 and higher devices include battery optimization features, which shut off the phone's WiFi when the phone goes into sleep mode or enables the Lock screen by pressing the Power button. The CoreNexa app can be optimized to limit battery usage by, among other things, preventing apps from using the WiFi connection.
To turn Battery Optimization off, please follow these steps:
- Tap the Settings icon
- Tap Device Maintenance
- Tap the Battery icon
- Tap the Battery Usage icon
- Tap the More icon () and select Optimize Battery Usage from the menu
- Tap the down arrow and select All Apps
- Scroll down the list to locate CoreNexa app and swipe the switch to the left (off)
