My voice muffled on calls unless I use speaker
Hello, I've seen a couple variations of this question but not my exact problem on the iPhone 6. When I speak to people on a call, they say I'm very muffled; however, if I put it on speaker they can hear me fine, and I CAN record voice memos, video, etc. This is a brand new headphone/lightening charger/speaker assembly. Sadly, I can't go back to the place that did it because I'm now posted overseas.
Any thoughts? There's no gunk in the microphone, and it's not the case - have cleaned and swapped out cases and tried no case - no difference.
Is dit een goede vraag?
