Replacing a note 4 screen (N910F) - will it work with a N910P Screen?

I have a N910F digitizer + screen that needs to be replaced.
I found a N910P digitizer/Stylus Flex + frame, just have to move the motherboard to it and reattach the ribbons.
The question is are there any difference between these two?



Another question; the volume button is a little wonky, I have to press on it really hard (the button on the motherboard not the physical button on the frame), is soldering required to replace it?

Thank you.
