when did the first android smart phone come out
Smartphone In October 2008, the first phone to use Google's Android operating system called the HTC Dream (also known as the T-Mobile G1) was released.[29][30] It also had a large touchscreen, but still retained a slide-out physical keyboard. Later versions of Android added and then improved on-screen keyboard support, and physical keyboards on Android devices quickly became rare. Although Android's adoption was relatively slow at first, it started to gain widespread popularity in 2010, and in early 2012 dominated the smartphone market share worldwide, which continues to this day.[31]
History of mobile phones Prior to 1973, mobile telephony was limited to phones installed in cars and other vehicles.[20] Motorola was the first company to produce a handheld mobile phone. On April 3, 1973, Martin Cooper, a Motorola researcher and executive, made the first mobile telephone call from handheld subscriber equipment, placing a call to Dr. Joel S. Engel of Bell Labs, his rival.[26][27] The prototype handheld phone used by Dr. Cooper weighed 1.1 kg (2.42 lb) and measured 23 cm long, 13 cm deep and 4.45 cm wide. The prototype offered a talk time of just 30 minutes and took 10 hours to re-charge.[28]
