Earphones controls and inline mic doesn't work

[Android Central Question]

My Xaiomi basic corded earphones works perfectly but the only problem is the inline mic and controls doesn't work on my phone (Galaxy M20) while it does work on other phones (I tried my sister's Galaxy s4) but my sister's earphones inline mic and controls does work on my phone so is it my phone or the earphones ? The earphones are brand new btw

Sometimes, slight variations in manufacturing tolerances can make enough of a difference to prevent something working on only one device or accessory. So far as I can see, it could be the earphones or the phone in your case, but I’d guess earphones.

Welcome to Android Central! Make sure the phone's headphone jack is clear of any debris by blowing it out with a can of compressed air. When you plug in the earphones, make sure the plug is in all the way -- sometimes if it's not quite pushed in 100%, some of the functions won't work due to lack of proper contact.
