Check your mobile or Wi-fi signal
If you're having problems such as slow data speeds, dropped calls or audio issues, your mobile or Wi-Fi signal may be the cause.
1.
Check to see if there is a sufficient mobile signal on the phone by looking at the signal bars in the status bar. The more bars that are displayed, the better the connection.
2.
Check the Wi-fi signal strength. If you are connected to a Wi-fi network, look at the Wi-fi icon in the status bar. If no Wi-fi icon is shown, you may need to connect to a Wi-fi network.
3.
You've completed the steps!
