The Android version 4.4.2 seems to be pretty rushed: it lacks the full keyboard range. Ie when connecting a Bluetooth keyboard (which is easily recognized), you can choose not dt. Keyboard layout. I have not yet managed to somehow subsequently install (tips?). After all, you can install a keyboard app in order for input fields, where normally pops up a keyboard, no error message appears ("Google is not reachable").
But the worst thing is the change in KitKat 4.4.2 which no write access to the external SD card gives "non-system apps." (But is on Google, not the stick). In addition, the ext. SD card is connected unlike eg Samsung, ie the workaround described at XDA by the "platform.xml" is not working. (Which is, in turn, on the stick). This means that many popular apps do not work, such as Titanium Backup, dailyme TV, ... - Root Explorer sees the ext. Map not, it Exporer contrast funzt.
Therefore, it is only 3 star, even if the hardware is actually great!
Addendum: With the free App Market "Multilanguage Keymap Redefin" keyboard layout is the problem of dt solved..
