The Oppo N3 comes with Google Chrome as its preinstalled browser. The interface is the same as on any other Android smartphone - clean and minimalist.
Opening the tabs area reveals a list of tabs which can be closed with a left or right swipe. Incognito tabs are supported too.
Of course, one of Chrome's strengths is its ability to seamlessly sync with its 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 Reduce data usage option does what it says on the tin - Google servers compress the webpage (using Google-developed tech like SPDY and WebP) and only then send it to the phone.
Unfortunately, Chrome still doesn't offer a Reading mode like its completion from iOS and Windows Phone.
Note that our Oppo N3 also came with a proprietary browser using similar browser engine to Google Chrome. It was as fast as Chrome, and offers similar functionality. The Google sync is available only on Google Chrome though.
Perhaps the highlight of Oppo's homebrewed apps is the Security Center app. It lets you control all sorts of features from call/message privacy and Quiet Time settings, to phone optimization and app permissions, app encryption, to network and battery usage. The phone's Guest Mode is also activated from within this app.
The Oppo N3 comes with Kingsoft Office preinstalled. It's a pretty powerful office editor that can handle Word docs, PDFs, Spreadsheets and Presentations. It can link to cloud storage, email files, create a shared view with other users and more. There's editing enabled too so you can even get some work done on the go.
Kingsoft has since dropped support for its Office application, and has instead published an updated version under the name of WPS Office.
The calendar app has three views that you can swipe between. First is the Year view, which aggregates all 12 months with all of their days, a month view, which has little red dots for events and the agenda view, which is a vertically scrollable grid of events.
Sadly, year view doesn't show little dots for events even though the screen is large and high-res enough to allow it.
The clock app supports multiple alarms, each with its own repeat time, ring tone, volume, snooze interval and note. The app also offers a world clock, a stop watch and a timer.
A Calculator app is available, too.
The Keep app lets you create complex notes with text, images and hand drawn notes. You can even set a password for your notes.
The Tools folder is preloaded with a few apps that you usually have to get from the Google Play app store. There's a Flashlight app, a sound recorder and a 3D compass.
The phone comes with a capable file manager out of box. Its interface is laid out over two tabs, the first one organizes files by category, while the second is a traditional folder browser.
Files and folders can be copied, moved, deleted, renamed and compressed to ZIP (and ZIP files can be extracted). Batch operations are supported. The folder browser has list and grid views and you can change the sorting method. The system can be encrypted and password protected, too.
The file browser also has built in DLNA and FTP server support, which makes it easy to access multimedia and general files on another device.
Google Now, accessed by swiping up from any of the navigation buttons, integrates with your Google account and can access your daily routine, internet searches, mailbox, etc. and give you information relevant to your interests and daily needs.
It provides traffic information to your work or home, it knows the scores of sports teams you follow and gives you the weather forecast for your location, tracks your packages, and fetches you relevant info for your upcoming flights and hotel stays.
It's great for at-a-glance info, but can handle voice Google searches as well. It also has a dedicated homescreen/lockscreen widget.
The Oppo N3 comes with a GPS/GLONASS receiver. A-GPS can speed this up quite a bit, but requires Internet access.
If rough positioning will do, Cell-ID and Wi-Fi positioning are on it. Wi-Fi positioning can work even if Wi-Fi is disabled or you can turn this off to save battery.
The Oppo N3 comes with Google Maps and Navigation. These offer voice-guided navigation including public transport connections but require an internet connection.
Maps show alternative routes and you can see alerts if there are any potential holdbacks along your route like construction zones, traffic jams and so on. Google's involvement with the live traffic info crowd-sourcing app - Waze - seems to be paying off.
The app also supports the Street View mode, allowing you to see the landmarks you're looking for before you set off. That makes them much easier to find when you arrive.
The Google Play Store features several scrollable tabs - categories, featured, top paid, top free, top grossing, top new paid, top new free and trending. Apps usually have several screenshots (some even offer a demo video) so you can get an idea of what the app looks like before installing it.
