My S7 was upgraded to G930VVRU4BQA4 on 3/27/2017. I noticed that night that the front facing flashlight (LED) did not work. Today, I tried to take a picture using the front facing camera and it doesn't work.
Can I roll back to G930VVRU4BQA2 that was installed on 3/6/2017 or is there some other way to fix the software so that the front facing camera will work (as well as the flash/LED that is used for the flashlight)?
