No audio in the ear-speaker during the phone calls in my iPhone X
Recently, I bought the iPhone X and sold my iPhone 6s Plus. I transferred my data to iPhone X through iTunes. And I am using the newest version of iOS 11.2.
I have being facing some serious issues in the new iPhone that is during a phone call there is no sound in ear speaker on the device. However, it works when I switch on the speaker. Meanwhile, sometimes both of them does not work.
It works perfectly fine when I restart the iPhone X.
This should not happen on a $1149 phone :(
Please tell me what is the problem? Is it hardware or software? I hope it is software.
And Please advise the solution to this problem.
I would be really grateful. Thank you in advance for your support.
