I’m with you. I think it doesn’t make sense to order new ones because I think it’s not the module which is broken but the connection or something on the mainboard.
I friend hat it’s bottom module replaced because of charging issues and I tried it as a replacement for my mic issues. But it didn’t help.
I want to send my bottom module to inspection to see whether I’m correct. In the meantime I can use my phone without my bottom module (charging is now broken too and mic is not working anyways. the vibration notification im rerouting to my miband fitness tracker and the sound output to the headspeaker) Maybe I can build in a new USB port myself for future charging possibilities.
