Does the Lollipop Android version allow simultaneous opening/use of a min of 2 (user-installed) apps?
KitKat had only limited capabilities/types of apps that could be opened at the smae time. User installed apps did not seem to capable of using this feature available on any WIndows PC..
The split screen option is easier to use, but still limited to a small amount of predetermined apps such as FB and YouTube, etc.
