Ear Speaker + Loud Speaker Not Working only when on Calls
As title says, strange issue with a Samsung S6 Edge.
Started happening randomly couple days ago. Not dropped / exposed to water / updated in any way.
When on call the Loud Speaker and Ear Speaker don't work at all and intermittently sound with buzzing / static.
Outside of calls, both function perfectly.
Tried full factory reset, different sim cards, checked internals all looked okay.
I'm thinking some sort of interference issue? Anyone have any idea what this could be or what is causing it?
Any help is greatly appreciated - thank you!
Is this a good question?
