[Android Q&A, Help & Troubleshooting] 0siribix:
I had to do a factory reset on my wife's Galaxy S4 SGH-I337. Now I'm trying to find some pictures that were lost in the format. I know how to mount things in linux but for the life of me I cannot figure out how to get to the /storage/emulated/0 part

here are some outputs that may help someone else figure this out
