The OnePlus One has Android 4.4.2 KitKat, layered with CyanogenMod called 11S for better performance levels. The CyanogenMod 11S is close to the Cyanogen 11 but with some additional features, and these are to some extent, specific to the OnePlus One. These additions include a custom lockscreen, which looks like a blurred layer on top of the wallpaper (the basic swipe-down for unlock and swipe-left for camera works here) – the custom lock screen can be disabled as well. The buttons can be assigned custom shortcuts for long press.
The home screen is the standard Android issue, though the rounded icons used throughout are specific to the One. The usual home screen customization options are all present, though the widgets are no more a part of the app drawer – they can only be accessed by a tap and hold on any vacant space on the home screen. Most widgets can be customized for size also.
The dock can be customized, icons can be moved around, and shortcut keys are present on each side of the app drawer key. The Google Now home screen has been removed from the equation for the CyanogenMod. The standard wallpaper modification can be done, a screen can be made the default screen, and transition effects can be defined also for home screen swipes. The Recent Apps section is unchanged, though a Kill All option has been added – this is CyanogenMod after all.
The notifications area is almost the same, the access to settings is standard Android – the only minor improvement is that on swipe-down on any notification, it expands or collapses, while swiping to the sides dismisses them.
A Themes sub-menu has been added to the settings, allowing selection of different themes, icons, styles, fonts and startup animations too. Customizations can be done to the quick settings panel, the status bar, the notifications drawer, and gesture shortcuts can be added too. There is a huge load of features in this area, all of which cannot be discussed with the limited space we have. Users can specify if they want the standard buttons below the screen, or to use the on-screen keys instead – selecting the on-screen keys disables the buttons, and puts up the on-screen keys at all times other than for specified apps.
A feature similar to the Nokia implementation is the Quiet Hours mode, where sets up the Do Not Disturb for configurability. The complete set of activities including the allowed people, mute notifications, among others are present. The Secure Messaging allows for encrypted messages exchange between CM 11 sets, while the Privacy Guard allows to setup which information can be accessed by apps. The OnePlus One, though running CyanogenMod, is still a pretty stable smartphone, and during our test drive, never faltered.
The phonebook, and dialer are standard Android issue, with the basic features all in place to cater to different requirements that they may have to cater to. In-call screen is also the default Android version.
As far as the call quality is concerned, the audio levels put out by the OnePlus One is excellent, with a crisp and loud sounding earpiece, coupled with good signal reception. The loudspeakers performed remarkably well too, with the exception of some bass issues, though we feel that our expectation levels have been raised too much by the HTC One series we are afraid. Still, the audio is the loudest we have heard in a while from a smartphone.
Google Chrome is the default browser for OnePlus One, refined to a decent level by Google to have a minimalist UI. All the standard options are available.
The CyanogenMod comes with some pre-installed apps, some of which are worth the mention. The CyanogenMod has its own File Manager, with the basic features, though a lot of taps are required, and we eventually downloaded an alternate from the Store. The Torch app is standard, using the LED as a flashlight. A Calculator app and Voice Recorder apps are here, as is the Clock, and the Calendar app. Another interesting app is the Screencast app, which lets you record the usage of your smartphone, as well as audio recording for comments being made verbally in parallel.
Google Now is available with its set of features, like informing about traffic situation on regular routes, relevant sports and weather information, among other things. It also has voice integration which can assist with multiple tasks like call launch, message taking, directions, or opening up a website being some of the many features. Google Maps is utilized for navigation related tasks, as well as navigation with audio support.
