I have a problem with my droid dna. Yesterday the phone fell from my hand and now I think the volume keys control are broken because when I tap the two buttons nothing happen.
What can I do to resolve manually the problem or with something else?
You can try to restart and factory reset, I would start there. Are the buttons damaged? Did the phone fall on them? If all else fails watch a teardown video of the phone and disassemble to see if it fixable.
