Where did you buy your S4...? SME set..?
If SME set and you have register your phone warranty already then you can always pass the phone back to SME for exchange if you feel that phone is a fake.

will drop around rm1000 in a year 
maybe send to sc check? since you have warranty..

I feel it Is definitely better than nexus 4
See my posting details about 2 days back on this showing SOT n battery usage
Battery drain with 3g on even overnight 2-3% over 7 hours is common

Anybody got this problem?about camera apps that slow and alway reboot..i got this problem..

I dont find any solution for now..huhu..maybe software problem..

Users having such camera /reboot should send in to service center. If is firmware issue everyone will be affected n not only few users
Mine is perfectly fine since day one till now

You still don't get my point
It is not a firmware issue. If so every user will be affected

I have yet to experience the the phone rebooting while using the camera..however I do notice the slow boot up the camera

But as a casual user - I'm fine with it (almost similar to my Desire HD..so I'm used to it)

As for smoothness - I admit Iphones is smooth..but the S4 is ALMOST as smooth as the Apple products (I've got Iphone 4, 5 and an Ipad 2 at home - belonging to family members but I've had fair share of usage) I guess I'm not a perfectionist and I'm not picky

I also noticed the demo units has this default "Demo" mode? MAYBE (I'm just assuming from being a casual Android user) that mode takes abit of processing? That's why the lag? I've been using my phone for about 4 days now..I felt it's better than those demo units?

PS: Demo units tested at Digi Store in Sunway Pyramid

Oh well..that's just me

Anyway..I bought the new Papago! SG & MY on Google Play..just for your info..it seems to not work properly as the maps downloaded to your SD card could "not be found"..when I browse through with the "My Files" app..the files could be seen..

I've sent an email to Papago to help me out..so..those planning to get Papago! Better hold your horses for now

Is this your version of Papago?

I'm getting this error
