Do i need an accelerometer replacement?

[CanadianWinter]

Today I dropped my phone when getting out of the bathtub (S5 Neo) when I picked it up the screen wouldn't rotate and I thought just a software glitch but I tried everything and still won't work the Gyro is fine, so is everything else except the Y axis on the accelerometer. I normally wouldn't give one but the camera app is stuck upside down and won't turn up no matter what is there anything I can do if there isn't anything then would CPR or a repair company be able to replace the accelerometer or no?
