If you can’t hear sounds on your phone, check the following: 

• Check that the volume is turned up. 
• Check that silent mode has not been available. 
• Inspect the speakers for any visible debris that may be blocking the sound. Remove with a soft brush if necessary. 
• Reboot the phone by turning off and on. Alternatively, press and hold the Power and Volume Up button for 15 seconds. 
• If the sound issue only occurs on a specific app, check for any app updates. 
• Check your phone for any software updates. If available, update the software. 
• If your phone has Do Not Disturb mode, try turning this off. This mode silences sounds and notifications. 
• If you are using headphones, check that the headphones are secure in the phone. If necessary, try another pair of headphones to determine if the headphones are not producing sound rather than the phone. 
• Check if your phone is connected to another Bluetooth device and disconnect if necessary for the sound to come out of the phone direct. 
• Perform a Factory Reset. Please note, this will erase all data and settings from your phone.
