In 2012, an estimated one billion smartphones were in use worldwide.

Android and iOS iPhone systems dominate the cell phone operating system market.

Smartphones before Android, iOS and BlackBerry, usually had the Symbian operating system, was the most used operating system in smartphones until late 2010.

Smartphone screens range from 2.45 inches to 5.2 inches (these called phablets, mix between phone and tablet). The vast majority of today’s smartphones have virtual on-screen keyboards.

They use LCD technologies mainly, other less used technologies: IPS, LED, OLED, AMOLED and E Ink.

Braille displays for the blind, using microfluidic technology, are expected soon. The future of the smartphone

Some estimated technologies for the next few years will be OLED screens that bend. They are expensive to produce and a small particle of dust during their manufacture can ruin them. Batteries that bend is a difficult thing to achieve.

Charge smartphones with solar energy or using the electromagnetic signals of the environment: radio, wi-fi signals, cell phone signal, etc.

An improvement in battery technology is also expected, because progress in this area has been scarce in recent years. Android’s slowness over time
