recently I bought i secondhand iPhone 12, but I was scammed.

The iPhone doesn't charge with the lighting cable. It charges only with the wirelessly charger. Actually, when the phone is off and I'm trying to charge it by cable, it is showing that is charging, but it doesn't. (Battery level doesn't go up.)When the phone is on and I'm trying to charge it, then nothing happens, no charging indication at all. The wirelessly charger is working.

Firstly after I bought the phone, the battery died at some point, because it went to zero, so I try to charge it, but the battery was completely dead. I went into an apple store and they told me that it was probably water damage, but the guy wasn't really sure, because he couldn't see clearly the water indicator. He mentioned that he couldn't see any corrosion to the port and that the port seems to be clear. They didn't try to charge it wirelessly. They connected a diagnostic tool and they said to me that they were receiving some signals, but they were too slow, so probably I have a bad motherboard. After this, I bought a wirelessly charger, and the phone charged and start successfully! It is working ok,(except for the ear speaker, which is too low, barely you can hear it). If a try to connect it to my mac, then sometimes I'm receiving a USB indication to the iPhone for some seconds and then nothing. Do you think if I replace the charging port board, it will fix the issue? I'm planning to "bath" the board in 99.9 alcohol, too.

I can not contact the guy who sold me the phone, nor Apple is giving me his details.

The issue popped out of nowhere too, it worked one day, went to bed and it stopped working the next.

Other than that, the phone works fine, but trying to look at the panic logs didn't provide anything of use either

Lemme know if you have any solutions to this!

here, idk if that’ll help

I replaced the buttons with new ones, there are no gaps, everything is fine, but I'm lost, I can't understand how long the screws are needed…

Everything is fine, but when I tighten the screw to the end, the button is not pressed, although everything is in place

Could you please tell me if I need to buy these screws separately? And are they sold on AliExpress? What length of screws for buttons do I need?

A few days ago I replaced the rear glass on my iphone 12 - it went relatively smoothly, but I managed to accidentally break the flashlight off during the replacement - the rear camera still works fine (without the light / flash of course) - but the front camera doesn't work at all anymore - is this because of the flash ? - If I replace the flashlight ribbon, is that likely to fix the front camera problem?

I don't know if it's something different - but face ID still works fine! - does that use the front camera or is that a different component again?

Thanks

I am planning on buying the new phone in September, but I am wondering if it's worth taking the phone to Apple to get my battery done in the interim, even though I plan on buying a new phone.

However, I moved back the earpiece to the original screen and brightness just worked as it should. Then I put it back on the new screen and it doesn't work. Of course, for sanity check, I moved it back onto the original screen and it all just works.

Is it possible that the new screen needs to be reprogrammed first for the brightness to work? What a goofy issue.

I am considering replacing the battery in my iPhone 12 since it has begun to degrade a bit in terms of battery life but isn't too far gone (yet) so I'm not in a rush to get this done for the time being. Overall I used to get 1.5-2 days easily (I bought the phone used, so the battery was at ~98% since I had it); now it is down to ~24 hours after 3 years.

Based on the battery data, am I due for a trip to the store to get this done or can I hold out on this battery until the 15 comes out*?
*It's coming up due since this one is a few generations old at this point (currently 3, will become 4 generations old soon).

I opened the phone and tried to measure the battery voltage with a multimeter, but got 0v. However, I couldn't find a pinout online so I might not have been measuring it on the right contacts, but I tried all the contacts I could.

I was thinking it might be a battery issue before I tested with the wireless charger but now I fell like it could be something else. I don't have much experience troubleshooting this kind of issue, so any advice will be much appreciated.
