WHEN YOU SHOULDN’T USE ROOTING ROOTING itself is good thing to get most out of your smartphone, but if you are using rooted smartphone for any financial thing, like using wallet in mobile or using internet banking on your smartphone, here it may leads to theft data by any apps that granted su access.
using root you may unsafe your mobile, for me i used rooted smartphone before but one day i found some bad thing in my smartphone, i had root explorer and i was checking files in ROM in data folder i found some images that was screen shot of my mobile, and its tends to upload on an server. i was really shocked at that time, but no way that which app was doing that, because many apps using su permission. anyway if you too found things like this please tell me also.
