Google Chrome is unsurprisingly the default browser in the new OnePlus 2. Its design matches the material look and feel of Android Lollipop.
One of the Chrome's strengths is its ability to seamlessly sync with the desktop version, using nothing but your Google account. This allows you to open an article on your PC and finish reading it on your mobile phone. It also syncs your bookmarks and favorite sites.
The usual organizing tools are present as well - there is the massively capable Google Calendar, a neat Calculator, and Clock (alarms, world clock, timer, stopwatch). A proper File Manager app (Files) is onboard as well.
Google's highly capable Office package of Docs, Sheets and Slides comes preinstalled, as well as Keep and Google Maps and Navigation.
The MaxxAudio enhancements can be tuned either via the Music app's settings or within the standalone Audio Tuner app.
