[Sprint HTC One (M7)] rank78:
I wanted to compile a list of system apps we can get rid of, specific to the Sprint HTC One. We have different and renamed apks from other devices so I figured this could relief some guessing and headaches. This is a work in progress, please offer info as to what an apk's function is and/or if it is safe to remove. I've gathered this info from this link, this link, and this link in addition to my own discovery.
