The apple store have not got the know how to change the top flex assembly. They will replace the screen with the assembly already installed and hook it up to their pairing machine to enable face ID. I would try cleaning and repositioning the face ID components first.

I have never run into this problem after an audio IC repair. It is most likely around the connector area there are a few filters on both sides of the board that might not be making good contact. Also check the two power lines for touch when it is not working and also that no pins are pushed into the plastic of the connector.. The ideal tool for this diagnosis would be the iBridge. You didn’t mention where you put pressure on the board for touch to return, if it is on the CPU than you will need to re-ball it.

This is a very vague question but I would start with. 1.       Battery. 2.       Charging dock 3.       Screen. 4.       Top flex.

These are the symptoms of a faulty battery. Try another replacement battery and check the battery connector on the logic board.

Firstly don’t completely rely on Tristar testers. You will need to rule out the dock assembly. What does the battery info show in 3uTools? For the XR I have only had to replace the Tristar once it is usually Tigris and or the charging coils I now replace them all. The 8 plus I would replace Tigris and maybe Q3350.

The most likely cause would be a failing battery. Even though you have only had it for six months the battery can still fail and can produce the symptoms you are facing.

A water damaged iPhone 6 will eventually fail as the corrosion takes hold. In the meantime I would replace the charging dock connector. They are only a couple of dollars and will probably bring your sound back. While you have the phone open I would lightly scrub the logic board with 99% Isopropyl alcohol.

A new battery might fix it, if not it will be your charging dock assembly. If you are going to replace the dock assembly make sure it is a genuine one pulled from another board as some aftermarket ones have faulty or no sensors which makes the phone restart every three or so minutes.

Can Siri hear you? Is your voice memos greyed out? If you have these symptoms it will be the audio IC problem which is prone to the 7 series. This will need to be repaired by a reputable repairer as it will require microsoldering. If you don’t have the above symptoms you could try replacing dock assembly.

You could try a restore using a program called 3Utools. It has an option to retain user’s data and there is a slim chance if you know the passcode and the phone accepts it you might retain your data but this is a slim chance. Other than that there is not much you can do.
