[Sprint Samsung Galaxy S6] killerbuzz5150:
It turns out my problem was because of a module I had installed a Dolby sound app is some how breaking root access I know cause I installed it again and lost root when I system wiped it got rid of that and everything worked right again It won't let me uninstall the offending app do I have to factory rest again? Or is there another way to get rid of It? I installed it thru magisk here's the log file..for some reason not letting me load the file link so...copy and paste...
