I have an N5, rooted but otherwise totally stock on 5.0.1 that has a broken proximity sensor and light sensor. They will work for an hour or two after a reboot, then die again. I bought the phone after 5.0.1 was released, but was on 4.4.4 when I got it. The OTA wasn't showing up so I manually updated it using the Skipsoft toolbox. My mother also has an N5, not rooted on either 5.0 or 5.0.1, it also came with 4.4.4 but she was able to update via OTA. Her proximity sensor also doesn't work, not sure about her light sensor.
Should I try the fix listed here? What about my mom's phone? I'd rather not root hers if I don't need to. Has anyone else been having these problems with stock Lollipop?
Edit - of these three:
I could only find /data/misc/sensors so I went ahead and deleted it.
