iPhone 7 Plus mic/speaker/wifi issue
 

seems like a common problem with the 7. Apple won't acknowledge that an iOS update may have fried the IC.

The issue being when placing calls:
1. speakerphone cant be turned on
2. you can't hear through speaker
3. they can't hear you through your mic
4. wifi connectivity is spotty


anyways, the 7 Plus is just a backup phone but its not really worth anything . so far i got a quote to repair the mainboard IC for $125.

any cell phone repair shops that are recommended for iOS devices?

same as the searching for signal issue with some older devices

buy new phone, solved :D

Had the same issue and paid around the same price, some jap kid living dt "home business" type.
Been working flawlessly since
