When midrange meets privacy: the Oukitel K4000 Plus wants to keep your secrets secret!5
In comes the Oukitel K4000 Plus — the latest member of the super-tough K4000 family. It's a midrange smartphone, which sports special software features to set it apart from the competition.
Oukitel is working on a privacy feature to be baked in the phone's OS, which can be used to keep your documents, pictures, contacts, texts, call history, and even apps behind a lock. It's in the form of a private folder, which can be accessed in a few different ways.
The most mundane option is the simple pass lock — you can have the folder displayed on your home screen; after tapping on it, you need to enter your own password to unlock its contents. There's also a more secretive option — the folder is invisible and only a special combination on the phone's dialpad would open it. For the most paranoid out there, there's the option to create a fake secure folder with bogus “secret documents” inside, while the real one is safely hidden behind a second pass code.
As for specs, the phone rocks a 5-inch, 720 x 1280 display, a MediaTek MT6737 SoC coupled with 2 GB of RAM, and 16 GB of internal storage (expandable up to 32 extra GB). The juice box that keeps the lights on has a massive 4,100 mAh capacity. To top all that off, the handset is, apparently, extremely sturdy – you can see it survive an extreme durability test in the video below.
