A friend has two Transformer TF300 tablets, both upgraded OTA to the (apparent) same JB 4.2.1 version, but one has tablet-style notifications (lower right corner) with the Home, Back, and Recent apps buttons left justified on the bottom, and the other has notifications on the top (like a phone), with the back, home, and recent buttons centered at the bottom.
Is there a setting that controls the notification style, or is there some non-obvious difference in the software versions?
