Verbal communication is one of the most basic necessities of any phone user – whether it's a feature phone or a smartphone. If this requirement is not fulfilled, any user is going to be pissed off quickly.
If you are using a high-end smartphone like an iPhone, you will hardly experience any issue like no sound during a call on iPhone. In case, you face such a problem, here are a few solutions you can try before you go to Apple Store.
How to Fix No Sound Issue During a Call on iPhone
Solution #1: Clean the receiver of iPhone
This might sound a silly solution, but believe me this thing works. If your iPhone is exposed to dirt and dust, you need to keep the receiver clean and clear. Use a toothpick or any small pointed thing that is not made of metal; dig out all the dirt or dust gathered in the receiver.
Solution #2: Turn up the volume
While listening to music or watching videos, we tend to adjust volume; if you have lowered the volume by mistake, you won't be able to listen to the voice during conversation. So, better turn up the volume now.
Solution #3: Check the Bluetooth
If you have inserted a headset into your iPhone, you won't be able to listen to any voice or sound from the receiver or from speaker phone. You need to remove the headset to use receiver of your iPhone; moreover, if you have connected wireless speakers through Bluetooth, you should disconnect the speakers and turn off the Bluetooth: Launch Settings → Bluetooth → Toggle Off.
Solution #4: Reboot iPhone
Rebooting your iPhone can fix many small bugs and issues; moreover, it also closes many applications running in the background. For no-sound issue, you can restart your iPhone: press and hold home button and sleep/wake button concurrently; hold the buttons even after the screen goes dark. After a while, Apple logo will appear in the white background. Release the button as your iPhone is restarted.
Solution #5: Erase All Content and Settings
As a last resort, you should go for Reset your iPhone. Before doing that please make sure to take backup of your iPhone in iTunes.
- Launch Settings → Tap on General.
- Scroll down to Reset and tap on it → Tap on the second option: Erase All Content and Settings.
