hybrid computer

Very nice device working fine classical computer.
BUT in terms of the tablet function is quite different: fluctuating and unstable display brightness making impossible a game like Candy Crush (the screen moves but nothing moves).
Having little manual, I dragged trying to figure ... Result, I exceeded the return date for Amazon and ASUS service poses so many conditions for the return for compensation in a country I hesitate Eastern (backup, reformat factory condition, etc.)
Note that I encounters no problem with my Internet Kindle.
I further states that it is under one year warranty.
I wanted because I was hospitalized from June to August ...
So think carefully before buying.
