It cannot update supersu binary on my phone. I installed this app to upgrade from a previous superuser app. Whenever I open this app and try to update the supersu binary (using """"""""""""""""recovery install"""""""""""""""")  the phone reboots and a message is displayed """"""""""""""""signature verification failed  installation aborted."""""""""""""""" I wanted to give it 1star but I've heard really good reviews of this app from my friends who use it that's why I gave it 2stars .Will give it 5stars if this issue is fixed.""
