I thought I successfully replaced my iphone 5s battery. But when I try to use bluetooth devices on a phone call the person I’m calling can’t hear me and I can’t here them. I can listen to music and other audio (like audio books). I think the problem is the 4 screws that are 3 different sizes. I think I originally installed them incorrectly, then I moved them to the correct positions but by then I think I damaged something. Any thoughts?
I am sorry but you may need to change the The logic Board then you need to compare them and using the photo below hope this helps.
