Initially, the unit is running relatively smoothly and stable. The longer you use it, the more problems occur. The tablet will often hang suddenly and can not be operated for several seconds. From Standby, it awakes often not at all more and has to be woken up with a hard reset.
Most preferably, the tablet was still running with Android 4.4, with an update to Android 5 was everything worse.
I had Farmstead update to 2.2 solves the problems, but two days after I recorded the update now the total failure. The unit does not start and the screen stays black.
Let's see if the third unit is running better, otherwise it goes back quite.
After looking at the forum and in the recessions in the Amazon problems seem to be widespread
