Sudden Death Syndrome

Thank you! 

Anyway, what caused SDS? How to prevent it? 

Prior to SDS. There is a few signs.

1) I just notice my phone more laggy den usual, i tot its laggy cause more apps and data installed (3 weeks).
2) One day i notice my phone is bit hot. (Heat when you play high graphic game like RR3), I wasnt running any app in background.. end process but still same so i restart den it was fine (1 day).
3) A day before SDS, the phone shut down itself. I plug into power plug and switch on again. Work like charm.
4) SDS day, after work.. while doing gym, i check whatsapp a little in between session and next thing i knew. Its DEAD!
5) Took to Samsung service centre which is a stone throw away. Confirm SDS. Need motherboard replacement.
6) Yes if not mistaken it was on custom rom 4.1.1.
7) Phone is well taken care. No power bank charging and no charging while using. Sometimes i even off phone or switch to airplane mode for charging. No water damage. Dropped 2-3 times with rubber case but low impact (last was 6 months ago)

Bad luck:( Any one else can share their experience?

Yup , u r right on that . At least better then SGS3 where SDS happens after 3 months of usage and above . That is scary . Even on 4.1.2 , there r a few and i mean a few kena here in the forum . 1 of them is our kak fruitie

Is already 24 hours since I updated to 4.3 direct from phone download. Go keyboard stop responding few times until I reboot. So far so good, battery life is better too.

No factory reset at all

I already read the whole thread but still I dont understand.. very noob user here..

It means your device may just suddenly die.

Have u try to clear cache/data for go keyboard in application manager ?

I just did one reboot and everything is working fine. Preferred not to factory reset to maintain all my whatsapp group chat

Yeah.. I know.. but what caused emmc brickbug? How to prevent it?

I just check my Note 2.. seems like it has Insane chips... what to do???

Dont bother checking ..... Most will come with insane chip . Just update your ROM to minimize it . I have used Note 2 since b4 SME set came out , touch wood didnt kena before .

Thank you for fast reply.. Shall i update it to official rom 4.3 or any custom rom? Or leave it on 4.1.2
