For me,
I notice better battery life(when idle) With Gps, Mobile Data, Sync, Power Saving: On, I lost around 6% only for 10 hours.. Normally it would be like 1% every hour or (X amount of hour - 2 = % loss)

and Phone/Contacts opens up faster than before(but I still wont consider it as smooth as stock android)

can add yourself under display > notification panel

yup, but now got EMC2
maybe update no more haha
not really need it, hold power > choose airplane

Ya, the camera features is cool, forgot that part, he he.

Went to digital mall pj to get Sandisk 16gb sd card .... Most of the Sandisk packaging don't have the silver color warranty sticker ...wondering If it's fake .... End up bought from czone .... There are warranty sticker on it ..

not sure if its fake , but all of my Sandisk microsd got this warranty sticker on it

I brought mine and I can remember there is a QR-code for you to verify Genuine or fake. Mine is Genuine.. 

How much you bought the used set? I almost bought a used set too since a lot of S3 user are selling off their phone just for the S4 but found a very nice price for a new SME set.

Mine's a special case so the price was just RM1180 at 3 weeks ago. The best price I heard so far is around RM1350 for SME and 1199 for AP, maybe you can check around the Garage Section since the price may be varies from time to time.

S4 come, s3 drop like pangsai...
this kind of price, Satu Gadget dot com

Anyone try ??

If worried about protection then try Otterbox Armor Series.. With waterproof, drop proof, dust proof and crush proof features
