There is a very common fault in the iPhone 7 family called audio disease or audio ic failure. This issue usually starts with a phone taking a very long time to boot (sometimes 5 minutes) and intermittent problems with hearing people and people hearing you on the phone.
As the fault develops further the speaker phone option will be greyed out, voice memos won’t work and sometimes the phone will get stuck on the apple logo.
These are all very common symptoms and are a design flaw on this model. The fault develops due to flexion of the mother board near the sim reader, which just like touch disease on the iPhone 6 Plus is caused by tracks being damaged. The fault often develops after the phone is dropped of bent and can often arise after your screen breaks.
All these issues can all be resolved by removing the audio ic, repairing the broken tracks and rebuilding the missing padsZ there is usually one main line that breaks which is the c12 pad.
When we repair audio issues on the iPhone 7 we will run jumper cables to 4 different pads making sure that the issue will not return again in the future and strengthening the connection.
The jumper cables that are installed are much stronger than the original board traces making this a long term fix. On the rare occasion that the IC itself is faulty we can also replace this to guarantee a true fix.
