yes it can be rooted. and if you root it, you'll have so many advanced
options for call recording enhancements which you can not get on normal
android..
when you root your device, you won't need upgrades.. you will upgrade
and control your device the way you want.. but you need to know what
you're doing
flash a firmware, using Odin, .. download the firmware from
sammobike.com and flash the. tar file only.. in the AP slot.. your
device will be as good as brand new..don't forget to backup your
data..cheers
