Hi,
A happy user on one of the first PAdfone (version).
When checking software update seems no updates availabe.
Android version 4.1.1
build JR003L.CHT.Padfone-10.5.1.4.0
In running into apps which only do support as of version 4.2
Does this Padfone version allow higher Android versions ? Not Rooted ..
or is it technically not possibe?

Or is it simply downloading 4.4 and do an install of this version ?
