This sounds like a faulty battery. Replace the battery and it should be fine.

Remove the screen protector and see if it still has problems. If it still has problems I would take it back to Apple for a replacement as it should be still under warranty. If the problem goes away after you have removed the screen protector than try another screen protector.

Sounds like it developed a short. It could be a capacitor or one of the IC’s on the charging circuit that has become faulty. Unless you have a multimeter and know where to probe there is not much else you can do besides sending it to a repair shop. If you do however have a multimeter the first circuit I would check would be VDD_MAIN.

Practice is the key. The solder paste you use depends on whether you want it to be a phone again. If it was a CPU swap for data recovery I would use low melt (138 degree) if it was going to be a phone again I would use what you are using. The one tip I can give to you is make sure your solder paste is dry. I squeeze mine out in a tissue I do this twice or maybe three times.

It sounds like you have damaged the backlight circuit on the logic board. You can check this by shinning a torch on the screen and see if you have an image. The backlight circuit will have to be repaired by a competent technician as microsoldering will be required.

It is always best to remove the logic board on an iPhone 7 plus charge port replacement. After the replacement put the board back in and connect the flex to make sure it is in the right position. Than go ahead and reassemble the phone.

The only fix is to replace the screen and hope the water didn’t penetrate to the logic board. I would disconnect the battery and remove the logic board and lightly scrub it with isopropyl alcohol while waiting for a screen.

You need to purchase an iPhone 6 front camera flex assembly. They are not very expensive.

Try putting the phone into recovery mode and update it with iTunes.

It is hard to diagnose this problem over the internet. ·         Have you ruled out parts by putting it into a known good housing with good battery? ·         Are you using your multimeter correctly? ·          Red probe on ground? ·         What is the history of the phone? ·         Has it had an audio IC repair done? ·         Have you put it in DFU mode and tried a restore or recovery? ·         How much current is it drawing on prompt to boot?
