The power button is basically stuck down and will not function the switch. Is this more likely a power button replacement or a Power & Sensor Cable replacement? (which parts should I buy) Or is it an indication the power button bracket is broken? (no repair listed) The phone was dropped.

I had the same issue and I can tell you that you just need the cable cuz the button bracket is broken. I just replaced my cable and I have a working sleep/wake function :)

Awesome. Thanks I’ll give it a shot
