Physical Characteristics
Having a phone that fits well in your hand and doesn’t weigh you down will go a long way to make using your Smartphone a pleasurable experience. A Smartphone’s physical characteristics are therefore an extremely important selection criteria. In addition to its weight and size, a Smartphone’s shape or form factor will likely play an important role in your selection.
If the phone you’re considering has a slide-out, rotating or disappearing keyboard, consider how comfortable the extended size is in your hand. Is it easy to grip? Do you need one or two hands to operate the device and is the keyboard easy to use?
Excessive size and weight encumbers mobility. Poor grip makes it hard to use.
