In addition to the charger, the included accessories of the Blue Devils W3HD also include a Micro USB cable, Micro USB to USB 2.0 cable, and headphones. The screen uses an anti-glare technology layer to achieve a more translucent display effect and a corresponding improvement in brightness. The layering of the picture is enhanced, more dark details are restored, and it has a wide color gamut. Maybe it's because of the addition of a special layer that the screen appears green.

The right side of the fuselage is where the interfaces are concentrated, including the Micro USB interface, reset button, Mini HDMI interface, headphone jack and Micro SD card slot. This machine has excellent audio and video capabilities and plays 1080P high-definition videos very smoothly, so it is very necessary to be equipped with a Mini HDMI high-definition interface. It will definitely be more comfortable to enjoy high-definition videos through an external high-definition device via a data cable. As mentioned earlier, the Micro USB to USB 2.0 data cable can make the machine support USB 2.0 and allow external 3G.

In terms of hardware, the Blue Devils W3HD uses a Cortex-A8 processor with a main frequency of 1GHz. It comes standard with 512MB of memory and 8GB of storage space. The overall performance is good. It supports two-point touch, which can be used for operations such as zooming in and out of web pages, but the experience of multi-touch games may be worse.

The 7-inch Blue Devils W3HD is one of the masterpieces of small-size machines in the thousand-yuan range. The greenish screen is due to the added anti-glare technology layer, which makes the picture more layered. Although some aspects such as multi-touch and battery life are mediocre, these are acceptable for a product under a thousand yuan.
