[usera3kLtCJUoT]

Tried clearing cache Tried factory reboot Re installed SIM card Restarted in safe mode Still no change and extremely low call volume

[user7rkINeLkWN]

This worked for me! After trying everything suggested, nothing helped. Putting the phone on safe mode did it. When in safe mode, the volume was normal. I restarted and made a call. My in call volume is back to normal now. 

Thank you so much.

I had experienced the same problem. I tried cleaning the speakers with alcohol, but it didn't work. 
I tried clear cache AND  clear data from phone apps (3 apps in my case).  Even though, when you attempt to clear data, it shows a message, advising that "All of this application's data will be deleted permanently..." , I went ahead anyway and clicked "OK"; it didn't affect the phone and deleted any contacts or recent phone calls, etc.
Then, I restarted the phone. It worked like a charm, sound on calls are back to normal (voice and ringing are back to normal. 

Hope it helps, good luck! 

**How to clear cache and clear data**
Go to Settings>Apps>Click on the three dots at the top right corner>Show system Apps>Phone (All three)>Storage> Clear Cache>Clear Data

Clean the ear speaker.  Ear wax. Hair products. Sweat  

Clean with fine brush and compressed air

I certainly want to assist you all further with this matter. To better do that, can the Community have the exact model number and Baseband version (both under Settings>About Device) for your device as well as your carrier? Thanks!

This device is too expensive $1,000 to have this sort of issue.  I cant hear ANYTHING clear at all every since a few OS udates ago and my phone is brand NEW
