Build and Screen

Yezz Billy 4.7 is quite lightweight, helped by its construction material of matte plastic. The design is somewhat minimalist but efficient. Dubbed ‘the thinnest Windows phone,’ the phone has a thickness of only 7.2 millimetres.

It offers easy and comfortable grip. As its name already suggests, Yezz Billy 4.7 packs a 4.7-inch diagonal display with a resolution of 1280 x 720 pixels. The IPS LCD panel offers decent wide-angle viewing and clearer image details.

Camera and Storage

Yezz Billy 4.7 comes with a decent combo of cameras for a mid-range device. On the rear is an 8-megapixel with autofocus, while on the reverse side is a 2-megapixel snapper. These should do enough to impress in terms of image quality.

The smartphone has 8 GB of internal storage, which you may find sufficient for your storage needs. However, if that won’t do, the phone allows you to add up to 128 GB more with a microSD card.

Performance and OS

Under the hood, Yezz Billy 4.7 conceals a quad-core Qualcomm Snapdragon 200 to give you the level of performance and multitasking that should be expected in its price range. The chip runs at a speed of up to 1.2 GHz and comes paired with 1 GB of RAM and an Adreno 302 3D processor.
