Smartphone is a generic term that is used to identify cell phones that have additional capability in the underlying OS to perform tasks that are not particularly cell phone related. This is a place to list Smartphone devices that are particularly well suited for eBook Reading.
 Overview of eBook use
Smartphones use downloadable apps to provide eBook reading capability which can vary based on the app downloaded. Generally the problem with reading on a smartphone is the limitation imposed by the screen size. Some attempt to solve this problem by using very high resolution screens so that small text can be rendered clearly and thus are usable by holding the phone closer to your eyes. Most allow adjusting the size of the font or use landscape mode for reading. The newest version uses an even larger screen and has coined the name phablet to distinguish the increased screen size from the standard smartphone.
