Assalam-u-Alaikum,
Today i am gonna tell u very necessary information especially for Pakistanis that how to check their samsung mobile that whether it is geniune or not .So here is the way to check .
Type the code *#2663#
For S3 :-
If u have s3 so after insering that code on callpad, black screen will appear . On 3rd or 4th line there will be some code if it i9300 then this is good news for you because it means that ur mobile is geniune.
For S4 :-
In Samsung Galaxy S4 if ur code is i9500 or i9505 on that black screen then your samsung mobile is geniune .
For S5 :-
if u guyz have s5 , code for s5 is G900F,G900H.
lot of guyz nowadays facing problem regarding this topic . So , my advise to u guyz is that please must check these things before buying samsung mobiles as it is one of the leading mobile phone brand in Pakistan and some says most selling brand in Pakistan .
Thank You . :)
