Lately we announced quite a few Android Mini PC's here, including a few new flagships.
Android is used mostly for smartphones and tablets, and the "flagships" for these devices come now with 4GB of RAM (some even more) - and you would think that Mini PC devices, that handle 4K movies and high bitrates, might benefit from additional RAM as well - looks like manufacturers think otherwise.

So what can you do if you need an Android Mini PC with 4GB of RAM? You might want to take a look at devices like Digimansion DM-V6+.
Granted, Digimansion DM-V6+ is using Rockchip RK3288 and Android 4.4, both of which are not cool like the new kids on the block (RTD1295 or Android 6.0, respectively), but let's look on the bright side: the software had it's chance to get to a stable level.
