Is the headphones amplifier on the main board or on a daughter board?

I accidentally fried the left channel of my phone’s headphones amplifier. (by external 12V voltage, I was testing some sound circuits; that’s too bad)

Where’s the headphone amp in the phone and how to change or repair the damaged part?

I believe the DAC and amplifier are BGA-mount parts on the main board. Unfortunately, you’d probably would have to replace the entire board, unless you’re good with BGA soldering.

Good luck!

Thank you very much, that was valueable information! I've considered the options and unfortunately came to the conclusion that the operations are too difficult for me and maybe too expensive and/or risky for this case.
