The microphone issues may be caused by a hardware issue. The iPhone 7 and 7 + were notorious for two common issues, Baseband PMIC (power management integrated circuit) and Audio IC failure. Although they’re not really failures. When the phone flexes from being dropped or over normal use, these integrated circuit chips would pop off the board resulting in either the microphones and speakers not working or getting a “No Service” message with a warning triangle next to the service bar status. As far as the camera issues go that does sound like it may be caused by iOS. Does that happen with both cameras or just one of them?

Could be a defective display or if you didn’t disconnect the battery you could’ve blown the backlight circuit. If the old screen was still functional, hook that one back up to see if it works. You don’t need to worry about transferring the front camera and home button. Just connect the old display and power it on.

While a replacement flex cable is available, it’s very difficult to replace because it’s soldered on, right on top of a very sensitive display. Even a skilled microsoldering tech could damage the OLED panel. On top of that, it sounds like the device has liquid damage. So even if you do successfully replace the flex cable, the display may have already been damaged by the shorts caused by the corrosion. I would start by cleaning the corroded connectors with rubbing alcohol and a toothbrush.

It appears there was a recall issued in the US for the 2004 model year for transmission issues due to insufficient transmission fluid flow. You can check here if that recall as ever performed. Again, this is if you live in the US. https://www.nhtsa.gov/recalls

I know Qianli has a TrueTone Programmer but I’m not sure it works with the 12 series. If the device can’t communicate with the ear speaker components it can lead to a low brightness issue. Take it apart, and examine that it’s not damaged and properly connected. If it’s damaged, you can replace that assembly but FaceID will be lost permanently.

Sounds like you’ve got a defective screen. What happens when you put the old on on? Does it illuminate and show what’s on the screen?

No. You’ll need to get the screen replaced, it is physically damaged.

Sounds like there might be an issue with one of the microphones. If you go to this part of Apple’s website you can check to see if your device is still within its 1 year warranty or if you have apple care and they should be able to take care of it for free. https://checkcoverage.apple.com/ If its not under warranty and Apple won’t fix it for a reasonable price, call around your local repair shops and see what they can do.

By the sound of it you’ll need to replace the microphone. But in the case of the S10 lineup samsung made that harder. In previous models and models after the S10, the charge port which contained the lower microphone was on a separate daughter board which could be easily changed out. The S10 lineup has the charge port and it’s components directly soldered to the mainboard so you most likely won’t be able to DIY this repair without causing significant damage to your device. You could try to send it to a board repair specialist like Jesse from VCC Board Repairs or Jessa from iPad Rehab. They both have youtube channels you can check out and I personally use VCC for all of my board work since I’m not equipped to handle those repairs quite yet.

As a cellphone repair shop tech who has replaced hundreds of screen protectors, I don’t think it effects the coating at all.

Can the TouchID keyboard be purchased separately if the original seems to fail? I’m looking on Apple’s website and it doesn’t appear to be available, at least for the time being.

I would like to add that you’ll need a special tool to read and copy the serial number to the new Taptic Engine so that it will provide proper feedback.
