I have Xperia V 9.1.A.1.140 and I just rooted it using "Root Many Android" (see closer decription on XDA), and now I installed Titanium Backup and every time the app loads it requires permissions multiple times and every time I try to uninstall and app, why is that?
EDIT: And here is the solution - I also rooted it with motochopper (again described at XDA) which installs the SuperSU, and in now only asks the SuperSU for permissions only once and it's working fine now.
