Sprint S5 randomly reboots and gyrometer intermittently works

My Sprint S5 has had a few pretty nasty drops (in a Spigen Tough Armor case and tempered glass protector). The issue I'm having is the gyrometer will not work to switch orientation on the screen. It is not a software issue, it happens on stock, MOAR, and AOSP based ROMs where it intermittently works and then will not work and sames goes with the reboots. Last night I decided to Odin to OG1 but I still have the same issues. I'm guessing it's a hardware issue and nothing can be done to fix this?
