Hey jayeff I want to thank you. I took my Note apart and found out that my dumb self FORGOT the upper mic (noise canceling mic) you had mentioned in your answer. Luckily I had access to another one, I replaced it and now everything is all good
I have a similar problem. I replaced my screen without issue but now two problems have arisen: when I get a call I cannot put it on speaker phone--the person can't hear me unless I click off speaker and I use phone as normal to my ear. Then when I connect to Bluetooth in my car I cannot hear the person but I can still stream music without issue. Why is this?
Smacking the iPad won't help. You need a new digitizer (your glass part) and a new LCD (the black part you see on your iPad). https://www.ifixit.com/Store/iPad/iPad-mini-with-Retina-Display My reference in answering this question: I'm a repair tech with over 5 years experience and have worked on all iPads including the Mini 2
