Yezz Billy 4 Specs & Price

Yezz Billy 4 is more or less like a stripped-down and cheaper version of the Billy 4.7. The Billy 4 packs the same quad-core processor as its bigger brother, but comes with lower storage and RAM capacity as well as a WGVA display. It looks designed to compete with Lumia 435 from Microsoft.

Yezz Billy 4

Design and Display

The Yezz Billy 4 features a two-halve design to enable users get it open easily without excess exertion. The chassis has a clean finish that is somewhat both sleek and matte.

The phone comes with interchangeable back covers available in green, red and dark bluish-gray to enable you add personal touch to your own unit every day, if so desired.

It is 10mm thick and weighs 109 grams. The Yezz Billy 4, as you may have guessed from its name, sports a 4-inch diagonal touch display with WVGA resolution – same as can be found on budget alternatives like the Lumia 435.

Camera and Storage

On the camera front, Yezz Billy 4 packs in the same 8-megapixel rear-facing shooter with autofocus – similar to the one on the Billy 4.7. However, the device features a stripped-down 1.3-megapixel front snapper, compared to the 2-megapixel sensor provided on its brother.

On-board storage is halved to 4 GB here, so you will appreciate that up to 128 GB can still be added using a microSD card.

Performance and OS

The same Qualcomm Snapdragon 200 processor powering the Billy 4.7 also runs the show here. The chip is clocked at 1.2 GHz and is supported by an Adreno 302 3D processor as well. RAM capacity is also halved on Yezz Billy 4 to a rather low 512 MB.

Yezz Billy 4 runs on Windows Phone 8.1 mobile operating system, with a variety of useful applications.

Miscellaneous Specs

Yezz Billy 4 is equipped with a 1420mAh battery which should do a decent job, given the phone’s screen size and resolution. It has dual-SIM capability to allow you carry two SIM cards at the same time.

The two SIM slots provided appear to support 3G connectivity. Bluetooth 4.0 and Wi-Fi with Hotspot are available for wireless connectivity.

Pricing & Availability

Yezz Billy 4 is available in Nigeria. You can buy it at leading online stores in Nigeria, especially Konga. Yezz Billy 4 price in Nigeria starts at N16,000.
