No.

Then why u ask?

It totally depend on user of the phone. If you got use for root then root lar. If no then no need root lar.

I have had no problem with data. If you do, a few things to consider
1) Check if your telco is doing anything in your area
2) Clean your sim card contact
3) Maybe faulty sim card
4) Something else

Technically gone.

If you dun want to open up the s-pen, go claim warranty and exchange for a new one.

install addons detector, find apps that is causing these push notifications. uninstall those apps if you dun need them.

You meant u try to open up the charger and it explode.? Already unplugged?

Great app you should get it. I am still figuring out what else i can do with it.

Better dun plug it in anymore. Go get it exchanged.

Samsung never claim it is normal. How can exploding/spark in charger be normal.

Just someone wrote an article that the hissing charger is normal (not sure if the source is samsung or not). I dun think this 2 is related as the latest charger exploded does not have hissing sound.

Cos there is no proof that hissing sound causes explosion. Take time to read my post and the user's post, his unit got no hissing sound.

Mine got but very soft, my ear need to be right next to the charger to hear it. It is actually not a hissing, more like a very fast vibration. People says its caused by the high freq transformer required for fast charging rate and greatly reduce the size of the adapter. Thats the reason why we have such a small adapter head (almost similar to S2 size) but can charge twice as fast.

People with exploding charger should go make a report on the safety of the adapter head to SIRIM or some certification/safety body and CC to samsung malaysia.

Sure get instant respond.

Dunno don't have S3.

LOL. So no hissing sound is bad.

Frankly if u ask the aunty that sweep the floor she will also say charger got hissing sound is not normal. Dun need technician/engineer for that.

But you must know the fact, the note 2 adapter is different from other older adapters cos of its charging speed and small size. The technology/component used can/will be different. Thus u cannot conclude that hissing sound is abnormal as it could be totally normal.

Conclusion --> Samsung need to make a formal announcement.
