If you call me my phone will ring normally but upon receiving the call you can’t hear me neither can I hear you….Do you replace the audio ic? If you do how will I get in touch?
iFixit does not offer phone repairs as a service. They sell replacement parts and tools. You will need to look for someone locally in your area that does board-level repairs or micro soldering for iPhones. If you can’t find any near you, consider looking for a reputable store online that does mail-in services for iPhones. Medion iPad rehab which is pretty much one of the best does them for many customers globally.
