Added on December 3, 2012, 11:32 pmmaybe the t-mobile version will get faster than i9300 international because international using samsung exynos cpu, while t-mobile version is using s4 krait dual core..

the development of i9300 international slow down because of samsung didnt release the driver/code for the exynos cpu..

same as mine, maybe is first batch,
can you run this code and verify further
press
*#12580*369# (this only valid with stock rom)
to check software and hardware information
On the 4th line you have RF cal, that's supposed to be date of the first call made by your phone (in the factory I guess). And on the 5th line you have HW revision.

result should be something like:
RF cal: 2012.6.5
HW Rev.: MP 1.100

looking at the date, seems not 1st batch. maybe can continue to overcharge few more months and see how.

yours seems to be first but maybe 2nd batch..

if your phone is original SME warranty do you mind to overcharge every night?
try update to 4.1.1 jelly bean and overcharge every night, see if mother board will fry.

you flash your rom before? factory reset?

Added on December 4, 2012, 8:55 amusing usb the charging rate is low, so overcharge risk is lower.
overcharge means after 100% and still leave it keep charging.

from what i understand the rf cal date is the first call made from your phone (board), in factory they will do some sort of QC test.

hmm, maybe that SC has ex-stock to swap for you.

in oversea, there is a guy had a 16GB faulty, and because board out of stock, SC replace him with a 32GB board. he is so lucky

so your phone was the first batch as well? was it running jelly bean 4.1.1? are you charging using original charger?

touch wood touch wood.

looking at the first call seems to be first batch but hard to tell, because the problem randomly happened and nobody sure if it only affected first batch.


suspect reason for motherboard issue
# jelly bean (but there were also somebody using ICS or AOSP rom ended up dead)
# overcharge (some phone dead not because of charging)
# original samsung s3 charger (most of the user in XDa claimed that they were using only samsung original s3 charger all the while and ended up with motherboard dead)

i dont think is LED notification causing the sudden death.. just avoid overcharge your phone.

Added on December 4, 2012, 3:15 pmthanks for the clarification. I am now running CM10, so after samsung logo it will go to CM animation.

my binary status is now cleared to 0, just in case if the phone half brick..
