iPhone 8 Microphone issue
I bought an iPhone 8 Silver 256 GB 3 weeks ago. Just a week in to using the phone, I am having issues with my microphone. The other side can't hear me unless I put my mouth in to microphone and speak. I read other threads in this community but did not solve my problem. I tried different things like taking the case off, resetting the network settings and a couple of things, but nothing worked out. Do I take it to the Apple Store for troubleshooting? What do I do guys?
iPhone 8, iOS 11.2.5
