HI...,I am making this post after getting response from norton mobile on google play store.
the problem is..., I tried the sim lock feature of the software, by simply removing and inserting my sim card...some defects i noticed there is..
1) software does not identify original sim card...,it simply locks the phone..,this can get problematic in adverse situation like if you remove your sim in remote place and forget your password..
2) you cannot unlock phone directly from phone when it's lock...i tried to unlock it several time but it show password incorrect., you have to go to Norton's site to unlock it...this can also become problematic in adverse situation..like you have to run some where to log in to your norton account..
i hope my post becomes valuable for norton's developers.
