A smartphone is a portable device that combines mobile telephone and computing functions into one unit. It is a cellular telephone with an integrated computer and other features not originally associated with telephones such as an operating system, web browsing, multimedia functionality, the ability to run software applications, along with core phone functions such as voice calls and text messaging. Smartphones typically contain a number of metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, include various sensors that can be leveraged by pre-included and third-party software (such as a magnetometer, proximity sensors, barometer, gyroscope, accelerometer and more), and support wireless communications protocols (such as Bluetooth, Wi-Fi, or satellite navigation). The best phones offer you everything you want from a mobile device. They deliver great cameras, the performance you need to multitask and enough battery life. The existing brands for Smartphones nowadays are: Samsung, Xiaomi, iPhone, Nokia, Huawei, Google Pixel, HTC, Asus, LG, Alcatel, Infinix, Panasonic, BlackBerry, Tecno, TCL, Oppo, Realme, Gionee, ZTE, Sony, Vivo, Lava, Lenovo, Microsoft, and Motorola. The most popular brands of smartphones are: Samsung, Apple, Huawei, Xiaomi, Oppo, Vivo, Realme, Sony. Choosing a smartphone for yourself not easy task.
