Guys, there has been many report among the first batch (mostly from HK batch) that the bottom half of the screen turned yellow or has some sort of yellow tint after a week or two. I was among them :-( Sent mine back to Samsung and they replaced the whole screen assembly. There is also report about suction cup mark that appear like a dark circle at several spots behind the screen detectable in low light, black background and white font condition. For those who plan to but AP, take care.

Try removing the apps and you'll know. I don't face any auto reboot problem but I know few owners been having the problem. Just that the hotspot will hang after sometime (turning on for 6 hours straight) and I've to reboot it. BTW, my tab is rooted and on ZSLA2.

There is a lot of discussion going on in xda about this. Few owners included some pictures showing the manufacturing defects.

Check and make sure it's 2A or 2000mA otherwise it will not charge or charge very slowly. Many irresponsible seller trying to pass those 500mA or 1000mA charger as Tab compatible charger. A shop sold a dual USB port charger to me and said it's compatible with Tab but turned out no, even though the output says 2100mA. I was doubtful because 2100mA is total output but the charger has 2 ports so it should be only 1050mA per port, insufficient to charge the Tab. I got it returned but the boss show me black face. Never going back to that shop again.

Guys, could you try to press the lower edges where the Samsung logo is and to see if the screen becoming loose (detaching from the base)? Mine is.
