From the call-only cellular phone, mobile devices have pretty much evolved. The smartphone is a must nowadays, and manufacturers keep making more powerful devices.
The smartphone is more powerful, possesses more features and connectivity options than the basic cell phone. Some may in fact describe it as being between a computer and a mobile phone.
Types of OS and their particularities
The smartphone market is a very competitive one; be it from hardware or an operating system perspective. Manufacturers like Nokia, HTC and Apple continue to create more powerful models to grab the most market shares. However, the software is important as well. Lately, the conquest in the OS world has seen Apple’s iOS, BlackBerry OS, Windows Mobile and Android pitted against each other. Every OS usually develops and presents its compatible market place, just like Google Play or the App Store.
Features available on a smartphone
The richness of smartphones comes from the numerous uses that can be made thanks to applications. The little software makes use of the resources provided by the device’s hardware. Be it augmented reality, instant messaging, various games or utilities, like photo editing, the application pool is very rich depending on the compatible operating system.
The future of smartphones
The new devices that are being developed are still evolved and better than the previous phones. New technology, like RFID, is present on some models. This technology allows short range data transfer, and one of the most promising uses is contactless payment. In terms of connectivity, from the GSM network to 3G and Wi-Fi compatibility, the mobile phone has certainly gone many steps forward.
