Hi There, if you are having issues with your Honor 5X's incoming call volume, try performing a "master reset" on the device. First, make sure you back up the device to a computer or spare SD, then follow these instructions to reset the device.
- Use the Power key to turn off your device.
- Press and hold the Power button and the Volume Up key at the same time.
- Release the buttons when you see the Huawei logo on the screen.
- Use the Volume Down key to navigate to “Wipe data / factory reset” and select it with the Power button.
If that doesn't work, give the Honor Customer Support Team a call at +1-844-524-6667 and they can help troubleshoot your issue further. (NS)
