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!
