What the different?my said made by samsung

international forum a lot user reported that faulty were came from the batch with "made by samsung" unit..

so if your phone:
# made by samsung
# first batch which purchased within May->August
# running 4.1.1 jelly bean
# like to overcharge, or charge overnight
# using original s3 charger

then very likely will have this sudden death risk..

so, back to questions, i hope you dont mind to help answer several questions
1) when your phone died, were you charging the phone?
2) do you remember your phone was running which software? 4.1.1 jelly bean?
3) when did you purchased your phone? first batch?

do you remember your phone was running which software? 4.1.1 jelly bean?

sorry i might messed up a little, so your phone is working fine now and not having any motherboard problem?

got, but some old code. developer need new and more source code for RIL (i read from XDA but dont know what is RIL), and seems without proper code the development for 4.2.1 AOSP rom is slow..

i9100G s2g has got aosp 4.2 rom already, because it is using TI processor and has source code opened

you might not be so lucky.. but if you trying to fry your phone
large number of users were charging while phone on. make sure you running 4.1.1, using s3 original charger, run your battery to almost flat and charge overnight..

i have been switching between sammy rom (omega) and aosp (cm10)

Sammy pros:
# very good battery life even with stock kernel, even better battery life with 3rd party kernel like yank555.lu
# with samsung motion features, like the smart stay, turn to mute call..
# samsung multi-view feature

AOSP pros:
# faster, smoother
# on-screen virtual button (navigation bar)
# nexus alike
# get new android release faster than sammy
# skip song with volume button (this required mod in sammy rom, but only works in ICS, after JB the MOD not working anymore)
# 2g/3g toggle at notification bar

do you mind to talk more about both pros and also the cons?? thx a lot

pros of sammy are cons of aosp.. vice versa

refer to this link
http://forum.xda-developers.com/showthread.php?t=1779578

go to xda to find
# omega
# wanamlite

these 2 are famous and quite a number of users.

try touchpal, can input as swype, and there are few keyboard layout to choose from, very nice keyboard with prediction and learning

also, if you are chinese and you will like this keyboard, the chinese input is far better than google pinyin keyboard.

i am using siyah 1.8, feeling that battery life is not that good if compare to siyah 1.7 with same tuning.. not sure what causing it..

i will try this 1.84, and if the battery life still no improve, then will try yank555.lu kernel..

http://detail.tmall.com/item.htm?spm=a230r...&id=18096928193

this can charge both phone and spare at the same time. i am using this momax battery, excellent quality and battery life exactly the same like original battery.

you can send back to samsung service center they will replace for you.

are you not original set? try if AP company replace for you.. if not, then go back to samsung and pay for a charge

samsung replace means warranty continues, depends on whether they have stock for motherboard, some were waiting up to 3 weeks.

when did you purchased your phone? if you take out your battery, the sticker at the phone says your phone was made from where?

Made by Samsung?
Made in Korea by Samsung?

when it died, were you charging it? using original charger?

Added on December 10, 2012, 9:27 amyes, there is no such thing as 1 to 1 replacement.. even first 7 days of unit purchased also no 1 to 1 replacement.. damn malaysia law does not protect consumer..

i read at other forum, europe user can flash their rom or root it without getting warranty void. they are protected by some sort of open software law, so they are not limited to original software, they are free to flash their phone to whatever software they like.

no, first batch from korea is the batch with motherboard issue.. this is the most worrying part.

i read every pages in xda, multiple different thread from t-mobile verizon also. here is 1 of the hot topic:
http://forum.xda-developers.com/showthread...1&postcount=233

and for the pass few weeks i am actively gathering information from those who had their mobo died.

nothing official, but high chance, or timing or luck.


I worked in RMA line for international company, anything more than certain % failure rate is consider batch problem. but we will not officially tell customer they are using problem batch, but we will claim if they came forward with a faulty device.


what/how to make your phone high chance to get the motherboard fried:
# first batch
# h/w ver is MP1.100
# using original charger (only several users raise this concern up)
# charging overnight and charging too long after the phone charged to 100% (too many people fried their phone this way)
# running jelly bean 4.1.1 (only several cases reported saying their phone was on ICS or AOSP rom)



i respect your point of view, if you think i should not analyze this and help the others to understand more, i will delete everything and leave this forum.


good luck everybody.
