A:
Very useful but.... Brilliant app and the only app that allows me to overclock/underclock either the big or little cores on my s6 edge plus. Whereas all other apps only let me change the frequencies of the little cores. Knocked a star off for not being able to shut some of the cored down as as after i untick each core they reactivate straight away.
