need to pay yourself.samsung does not cover wear & tear damage afaik.

Guys, I have a problem with my s3. Lately my s3 always hang/freeze when Im using it. So i need to hard reset or take out the batttery everytime it happens. And it happens occasionally and kinda makes me worry. Do u guys know whats the problem? Im used Revolt JB rom before, and after all the hang/freeze thing I change to Omega rom, but the problem keeps happening. What to do guys. Plz help me. Btw Im using 16gb microsd class 4. Maybe this is the problem? Memory card too big and speed to slow or something?

around 600.nope.malaysian telco does not support fast dormancy yet.afaik.

Since you see a big difference in speed that means it is clearly supported.

guys, any of you here using the exynos abuse to root your phone? ? Its not working anymore after I update my phone to 4.1.2

Yes. I followed all the guidance on XDA page including doing the full wipe method. It not just happened after i change to Omega, but it happened before that when i used Revolt Jb Rom.   
My phone freezing like all the time. Not just when open the media/gallery, even when im using whatsapp or serve internet also suddenly it freeze and i need to hard reset the phone. So stressful. 
Oh man, i think my phone has few of the characteristics that u mentioned. My phone is freezing like every 5 minutes. Its just a bit better when I took off my microsd card, but it still happened (freeze) once in a while. Is that mean my phone will die soon? And let say it really happen (suddenly my phone is dead and still in the rooted mood), will Samsung fix it for me since I still got the warranty for another 6months.

RM600++ and 5 working days. Quoted from SC.

after long time stick to wanam rom, lately finally move to omega rom.
personally i feel omega is lot more better in term of battery life and also features rich.

Have anyone experienced the S3 screen just cracked out of nowhere? (no fall , didnt sit on it)

It was fine when i went out and take pictures at the beach. Once i came home, placed the phone on the room table and went for a shower. Came back and my phone had 2 hairline fracture.

Going to maxis to get it replaced, but i am expecting that they will push the blame on me for physically abusing it.
