Both are good, although SanDisk is more known for manufacturing storage media.

There would be minimal difference in terms of write and read speed.

both are good enough
but Samsung microsd is much more expensive than sandisk
yet sandisk is more popular on making storage media (flash drive, memory card)

Samsung microsd can read up to 70mb/s, write up to 20mb/s
but is around 20-40% expensive

I heard Sandisk Class 10 first batch got problem. I just used Sandisk Class 4, no problem until now. Other good option is Kingmax Class 6 0r Class 10, if not mistaken price cheaper than Sandisk. I like Kingmax RAM & thumdrive, still using it, small, cheap & reliable.

I read they sell 32GB Kingmax Class10 at RM79, refer http://www.lelong.com.my/kingmax-32gb-micr...3-10-Sale-P.htm

I would temporarily skip 32GB SanDisk Class 10 as I'm not sure if its a fixed version or the worldwide reported faulty version. Transcend, Kingston, etc are all branded and reliable brand for Class 10.

the biggest culprit of battery lost, Screen is the lowest usage.. this looks weird.. have you update your firmware to the latest firmware, XUBMG5 for i9505 or XUBMG1 for i9500?? then install Wakelock Detector to see what apps using the most cpu or trigger the wake..

just search in play store 'Wakelock Detector', or just click this link -> Wakelock Detector-Save Battery
your S4 is AP set? Malaysia official firmware dont have XUAMDK.. according to sammobile, XUAMDK is India firmware.. anyway, you still can update the firmware.. try install KIES on your PC, run KIES and connect your S4 through USB.. it should detect your S4 and search for the latest update..

Do you root your phone? If not, you can get update OTA by going to Setting > About Device > Software Update.

Else, you can use KIES to get latest firmware

did try to unplug your cables?

if urs is SME set , shouldnt be india firmware ... pls sms ur IMEI to samsung to check on warranty date , to ensure it is SME set ...

Exactly.....

Either owner reads somewhere wrong or he accidentally got an imported set (AP).....

Setting > About

XUAMDE is the first firmware release for Malaysia. You should get latest notification to update to latest XUBMG1 firmware, when you connect your phone to KIES. Maybe there is some bug in the earlier firmware to get OTA update.

XME = Malaysia

Was just answering to your earlier concern on India set..

OTA if you can't do it..
KIES if you also can't do it (Try uninstall/reinstall latest Kies?)

Then I suggest you bring to Samsung SC ....

welcome back to stock
u wanna better battery life, turn off all bunch of S and Air stuff

as well as turn off gps and lower down screen brightness.

I check gmarket doesn't seems so cheap too..

May I know where is this price quoted from?

The delay is meant for S voice . Press once, the device waits a few second for another click to jump on s voice app.

if you unhappy with this, simply go to the S voice apps , untick the option open via the home key

lol... how come so delay want?
