[Device Reviews and Information] HoustonReal:
The Onda V820w CH DualOS is an 8-inch, dual boot tablet PC, that runs both Windows 10 (64 bit) and Android 5.1 Lollipop. The “CH” in this model's name denotes a Cherry Trail Atom Z8300, Intel's latest 14nm, low power SoC processor. There are other Onda tablets with similar names, but the majority of them have the older 22nm Intel Bay Trail processors. Most are either single OS Windows 10 models, or have Android 4.4 Kit Kat as their second operating system.

I have been testing this tablet for over a week, and it works incredibly well. The 8” IPS screen touch screen is very responsive, and has a resolution of 1280x800 pixels (WXGA). While 160dpi isn't “retina” level resolution, pictures and text, appear sharp and colorful. I have read some older reviews for Onda V820w variants complaining about the dull screen. The company must have upgraded the original panel, because the unit I received is bright, colorful and looks great off-angle. The capacitive touch screen supports 10 point multi-touch.

Movies can be played in high definition, and the Cherry Trail's 8th generation Intel integrated HD Graphics supports DirectX 11.2 and a second display using MicroHDMI. The GPU is roughly 40% faster than the 7th generation HD Graphics (Bay Trail) and can handle many Windows video games. The GPU also supports 4K/H.265 video acceleration.

The System on Chip (SoC) Intel x5-Z8300 processor is the slowest of the Cherry Trail family, but it ranked towards the top of the 2015 heap, and still provides plenty of power for a tablet. I ran the AnTuTu benchmark app under Android and received a composite score of 59,241.

The tablet's audio capabilities are sufficient for normal, everyday use. The small, mono speaker located on the lower rear of the case will not fill a room with sound, but provides acceptable dynamic range and loudness to watch a short video or understand human speech without sounding strange or tinny. Watching a full-length movie or playing music really requires use of the headphone jack or a Bluetooth audio solution.

The downside of having a DualOS system is the need to divide the 32GB eMMC ROM into multiple partitions. The Android system is left with only 4GB for its OS and apps. The Windows 10 partition winds up with around 21GB of storage. The remaining 7GB of space is taken up with multiple recovery partitions for both OS environments. File storage can be easily augmented by adding a MicroSD card, but this won't help much with Android app space that can be easily overloaded. The Android OS is available for applications that aren't offered in the Windows 10 store, otherwise most users will consider Windows their primary operating system.

Using Windows 10 on the tablet is fairly simple. While using the standard desktop, there is a keyboard icon on the taskbar for typing and data entry. Alternatively, “Tablet Mode” may be selected, which switches to The Windows 10 Tile UI, and the keyboard is automatically popped up as required. One huge benefits of using Windows 10, instead of Android, is the ability to share files and printers with other PC's on a home or office network. Microsoft has left enough networking options in Windows 10 home that anyone should be able to setup a workable and secure network.

The Onda V820w CH DualOS weighs 335g, or just under 12oz. The case is all plastic, with a concentric circle “fingerprint” pattern on the back cover to reduce slippage. There is a flush “Windows” button along the lower edge that serves double duty as the Home Screen button in Android. Along the top right side are the on/off button and volume rocker. The upper left side contains the TF card slot. The top edge has the Micro USB, Micro HDMI and 3.5mm headphone jacks.

The are 1.9MP cameras at the top, front and back. These is no flash LED on either side, and the cameras work best in well lit situations. Unfortunately, there is no provision for using the camera modules to automatically control screen dimming.

The WiFi is provided by a 2.4GHz Broadcom SDIO 802.11bgn chip. The SDIO interface limits maximum speeds to 100 mbps. Bluetooth 4.0 is included as well.

The only other electronic feature is a motion/gravity sensor that allows automatic screen rotation. There is no GPS, or even WiPS/WFPS location functionality. Any applications that require location must settle for manually entered zip codes or addresses.

Overall, the Onda V820w CH DualOS is a great value. It out performs most Chinese MediaTek based Android tablets around the same price point, and offers dual OS versatility.
