That is the thing. You = not same as other people.
Different people got different uses for their phones. Some have important stuff on it, some don't. Some don't particularly care about their security, whereas some do.
As such apparently it's not useful for you personally fair enough, but we shouldn't say then that
nobody else has a valid reason to use it since i don't .......
if anyone finds it useful, good for them if not then no loss. This is the reason i bothered to post it in the first place for those who may find it useful for them.
Totally agreed with Xaectorz's suggestion for you to follow
My point is, this isn't such a big deal that needs to be debated or even create an issue out of does it ?

my 5cents..
With that out of the way, does anybody have any other security app to recommend to me ?

other than avast mobile security, adway, and anti spyware which i am using right now.....
i installed openvpn for android app because i wanted to set it up so i am connected between my android smartphone and my QNAP TS-659 Pro II NAS securely. Unfortunately the setup involving CA cert was a bit complicated, and from my testing it didn't work :[ i probably botched up a step or 2.
There was this other app call pdroid which has a good firewall that doesn't use much resources at all. But i haven't yet gotten around to using it yet. I'm not sure if it supports jelly bean as of it

I have installed Plan B and Lookout just to be safe now, once kena stolen now want to be safe, learned my lesson
last time lost my S3 and until now cannot find it and Samsung is not helping to even lock it for me
