A cell phone is any portable telephone which uses cellular network technology to make and receive calls.
The first mobile phone call was made 40 years ago, in 1973, by Motorola employee Martin Cooper. Using a prototype of what would become the Motorola DynaTAC 8000x, the first commercial cell phone in the world
In1983 the first commercial cell phone, was sold by Motorola at a price of $4,000. That cellphone weighed 790 grams and was 25 cm high, also it had a big antenna, a LED display and it saved only 25 phone numbers. It offered 30 minutes of talk time and 8 hours of standby,
Nowadays the simple cellphone practically has disappeared, most people use smartphones, a mobile phone with highly advanced features. A typical smartphone has a high-resolution touch screen display, Wi-Fi connectivity, Web browsing, and the ability to accept sophisticated applications. The majority of these devices run on Android, which is the most popular mobile operating system.
Here you can see the evolution of mobile devices from the first commercially available DynaTAC to the smartphones of today.
In my opinion the best smartphones of today are the Samsung galaxy S6, moto X and the new HTC one 9.
There were just a few grammatical errors, but overall, great job. It was very well written! ^_^
