Disappointed with Tab 3 7" topic

So I got my tab free with my note 3 (yes I can hear you say you got it free, what's the problem) and was chuffed until I booted up the tab, first the screen flickers (very slight but noticeable) is this a fault or the norm, secondly android 4.1.2 are samsung really releasing the tab 3 with 4.1.2 and I don't believe kk will be available until I see it, thirdly no Dev for it, fourth no hml or otg support, fifth it's slower than my HTC sensation. Now before I had the tab I was happy with my laptop/mobile combo but the tab has given me a taste for tablets. Rant over :P
