I ordered the tablet just before Christmas and it's even arrived on time (despite strike). I'm not a Computerspezi but simply users and could immediately get started with it. So far everything has worked very well and without complications. It was very convenient that it has apparently synchronized immediately with my S3 Mini, so I had all the same apps and no longer needed Download :-) Now I'm (unfortunately ;-)) every night with the tablet on the sofa and let the TV run by the way. Just as I had wished. So far, no requests have remained open. About the technology I can not say anything, I use it only for surfing.
