I just tried my note when calling . i dont really heard any "sa sa" sounds like what u mention just now ..
anyway telco problem or area problem ?
u have to find out urself =)

i'm using maxis

yeap... its in the link that i just gave just now. just came out recently lorr... probably gonna need to remove that link as well

Most of them is system file, map file depend on country...

juice defender was working fine for me ...auto shutdown data and wifi when i put phone to sleep ..  

go for ultimate version

u can try out the free version first then only make decision.. I read alot bout the apps feedback and what JD does was optimizing the phone perfomances when we didnt use it .. I am new to galaxy note so if any sifus can recommend better juz share it here

go to market to download antutu benchmark.. run the test, if it score 6k and above, it's safe to say that it's a original note...

call the dealer d but the number cant get it...
if call the samsung e-warranty department will it have the limited time? since the warranty card said activation should be made within 7 days of purchase

i swapped my black Note with a white one few days ago.. now suddenly realized that the white one i got, when charging, some buttons become not responsive (the lower end of the keyboard) while typing sms.     

     

is this confirm a hardware issue? i hate to send phone to service center, then have to wait for weeks!!
