the last couple i had were claimed top be rooted and many apps would not aork because they ere reportint the tab was rooted but i could not get root or get any deep uninstalling done so not sure what happens there
i have heard decent things about the MTK but its a shame it gets married with some cheap ass hardware and hence gets a bad name, but you have a ZTE so that should be a step up the ladder of quality so maybe their stocks are actually quite good
the problem i have is ot really with the power, we know they can kick some serious butt - its with build quality, even with the so-called brands like ramos and cube etc etc
here are the links google translatedhttp://translate.google.com/translate?h ... 26id%3D109
there does seem to be a firmware on that page for the ramos - again, not sure if this include PLAT or google services - you would need to find a review for that, maybe youtubehttp://translate.google.com/translate?h ... dminic4%2F
LOL - its been a while since i looked at a product page for a chinese product and they still massively over photoshop and misrepresent their products with dodgy - love the fact Teclast have chosen pirated images of Lindsay lohan, that bastion of all that good and wholesome, to show off their product - massive LOL
anyway, while i like the size of these iPad mini style tabs i would be dubious in getting one unless you had an easy and free route to return if needed- i know im a grump on this but thats just me being hardened to it now - they do look nice and maybe im beig harsh and things have improved ....
anyway, i really dont know about which chip and stock android s better but seeing as you have seen good things from MTK that maybe a good starting point
