Question: Mystery software issue causing no sound on calls
My iphone 6s has an issue where I don't have any sound on calls.
I have tried Apple's online guidance, swapped it for a new iPhone from Apple and tried a different network sim.
This leads me to think it must be a software issue, perhaps due to an installed app or my iCloud account.
- Restarting the phone temporarily fixes the issue
- When I swapped the iPhone I didn't restore my backup incase the issue was on that
- I have the latest ios, the issue has been happening way before this
Please can anyone offer some help?
