What is a User-Agent and what information does it provide?
Described in the HTTP standard, the User-Agent string contains a number of tokens that refer to various aspects of the request, including the browser’s name and version, rendering engine, device’s model number, operating system and its version, etc.
From a web developer’s perspective, User-Agent strings can be useful when it comes to testing how online content is rendered on various hardware and software combinations. What works well on Chrome Mobile and the latest Android may not work the same on an older device and browser.
Most common mobile browsers
The landscape of mobile browsers is quite complex, with several major players (pre-installed in most cases) and a number of locally popular contenders. While all phones come with pre-installed browsers, both Google Play and Apple App Store offer a number of alternative browsers, some focusing on speed and lightness, others on saving bandwidth and blocking ads, and an ever-increasing amount claiming to increase privacy and reduce a users' mobile digital footprint. (We discussed some of the more popular privacy-respecting browsers.)
According to our report on the most popular mobile browsers, Safari Mobile, Chrome Mobile, and Samsung Browser are the three most used mobile browsers across the globe. The report also lists a number of other locally popular apps for web browsing, such as UC Browser, Yandex Browser, IE Mobile, Opera Mobile, Opera Mini, Firefox, and MIUI Browser.

How to parse User-Agent strings
As you can easily notice from the list above, each User-Agent string contains a number of keywords that may obfuscate the device behind the request. For example, most UAs listed here include "Mozilla" and "Mobile Safari."
The result is that UA parsing solutions must be sophisticated enough to understand which elements of a UA are meaningful. A simple regex solution searching for keywords will struggle in terms of accuracy and detection speed. To make things worse, the number of UA combinations grows every time a new device, browser, browser's version, or OS version are released.
To tackle these issues you may want to consider using a specialized device detection provider, such as DeviceAtlas. It offers a patented algorithm that detects and identifies all devices requesting online content through parsing UA strings based on a constantly updated, massive list of connected devices.
