If you are struggling to hear any sound, or you are hearing low quality, distorted sound from your device, then the following steps may help:
Check your sound settings
If your device has a Ring/Silent switch, move the switch forward, toward the device's display, making the orange no longer visible.
For an iPad, you can swipe down from the top right-hand corner to view the Control Centre. Make sure Silent Mode is off.
Also, open Settings > Focus > Do Not Disturb and make sure Do Not Disturb is off.
Clean your speakers
Firstly, remove all screen protectors, films or cases from your device first. Check the opening of the speaker to see if it's blocked or dirty.
If necessary, gently clean the speaker or receiver opening with a small, soft-bristled brush. Make sure the brush is clean and dry.
Check the sound on your device
Go to Settings > Sounds (or Settings > Sounds & Haptics), and drag the Ringer and Alerts slider back and forth a few times.
Try making a call
If you still can't hear anything or hear static or crackling, then your network or reception could be the issue. Try calling again later or from a different location.
If you have completed these steps but are still experiencing an issue, please get in touch for further help.
