FOSSiBOT S3 Pro Design

FOSSiBOT S3 Pro has a perfectly refined form factor that exudes elegance and sophistication. The device impresses with its compact size, thin profile, and excellent build. Moreover, it delivers an excellent handheld experience. The device has 3D curved vertical sides both on the front and back creating an extremely slim profile, even though the overall thickness of the handset is 8.65 mm. While this depth is quite average along with the weight of 199 grams, the width and height of the model, are below average for a device with a 6.67-inch display and a 5000 mAh battery and contribute to the overall compact look and feel.

We are reviewing a Feather Green unit. The plastic rear shell has a matte finish with a feather-like pattern that creates a beautiful light-refracting effect. The frame is also made of plastic and is in matching color with a matte finish. A big circular camera island with a metal silver-colored frame graces the rear shell and houses one of the model's highlights - the secondary screen for selfies. The front is graced by the FOSSiBOT S3 Pro most attractive feature - the expansive 3D curved AMOLED display with extremely thin bezels (3 mm on top and bottom, 2 mm on the sides). In order to maximise the screen estate, the manufacturer has placed the earpiece on the top frame, instead of above the display. The bottom frame houses the speaker, USB Type-C 2.0 port, and the hybrid, dual-Nano SIM card tray. The right frame is the home of the Power button and the Volume rocker. The device features an in-display fingerprint sensor and supports on-screen gestures as well as virtual navigation buttons.

FOSSiBOT S3 Pro is built around a 6.67-inch AMOLED display with an FHD+ resolution (1080 x 2400 px) and a 60Hz refresh rate. It delivers a typical brightness of 500 cd/m² and a typical brightness in brightly lit environments of around 800 cd/m².

The curved screen provides vibrant colors and crisp details whenever you're browsing photos, watching videos, or gaming. From the display settings, you can adjust manually the color mode and color temperature. Always-on display (AOD) is also supported with various options for customizing its elements and color scheme. The AOD displays the time, date, battery charge, and notifications on the lock screen without the need to unlock the device. You can also customize the edge lighting features, choose a charging animation lock screen layout and signature, and enable Magazine Unlock to display a different wallpaper on the lock screen each time the display is turned on.

The Secondary display positioned on the rear shell occupying the center of the camera island uses a 1.09-inch IPS panel with a resolution of 240 x 240 px and a typical brightness of 400 cd/m². This display has a round shape and has various useful features. For starters, you can use it as a viewfinder and snap selfies with the main rear camera. This expands the flexibility and convenience of the smartphone for inspiring creative takes on selfies from different angles. In addition to using the camera, the auxiliary screen can display a clock, a compass, and the music player controls. It is touch-sensitive and you can access them simply by swiping to the left and right. A swipe-up opens the list of notifications. You can customize the clock face, screen timeout, backlight level, and the photo resolution of both the front and rear cameras.
