OH MAN. I worked on an Android tablet that used a rockchip CPU, not the one listed here but an older one (I think RK3026). What a PIECE OF SHIT. I don’t wish that tablet on my worst enemy. Battery life was like sub 2 hours with a 3200 mAh battery. Sometimes it would start running hot, and you could watch the batter percentage go down one percent every 10-20 seconds. The only way to break it out was to reboot it or let it die.
We later upgraded our CPU to the 3288, one gen older than this one, and it was significantly improved, but still very entry level.
I remember being upset about the exact same thing when 4G first launched.
