    Product information


    According with the manufacturer, or searching info on web pages, we can found many sources of information about the device and sometimes these information may be not consistent (may be different from one web page to other), and this may cause some confusion for anybody that wants to get info about this product.

    On this section i will post the info i get from the manufacturer (or is not possible, the web page that i consider more reliable), listing only the relevant points for a tech analysis of the product, and omit these points that don?t get any relevant info about the device (as many time we found on many pages, things such video capabilities, mail capabilities, etc, that really are software based features that we can install on the device, and not a real feature of the device itself)

    • Procesador Rockchip RK3188 Quad-core, Cortex A9 1.6GHz *
    • GPU Mali-400
    • 1Gb RAM
    • 8Gb de memoria interna
    • Android 4.2 (actualizable a 4.4 KitKat)
    • Slot para tarjetas MicroSD hasta 32Gb
    • Pantalla 7? 1024x600 TFT
    • Mapeador de teclas **
    • Bater?a de 5000mAh ***

    * En muchos sitios se especifica una CPU de 1.8GHz, pero el dispositivo va a 1.4GHz (con el firmware stock), y se puede subir a un m?ximo de 1.6GHz (con un cutsom firmware)** Tiene todos los botones del mando; inclu?dos L2, R2, L3, R3, Select, Start*** Dato corroborado con el fabricante

    Info from the device itself (Android info)

    In first place, to get a reliable source of info about the system, i take some screenshots from the same device showing android system info (thata usually is insufficient), and from another software that can give us more detailed information about the system, and with this info we can get a general idea about the capabilities of the device.

    Pros, cons and improvements.


    As in every product, there are pros and cons points that are good to mention in a clear way. These points will help to us to decide if the device features are enough for what the user are looking for in a device of this kind.

    Pros are based on features that highlight, comparing the device with another similars, or these features improve the experience of the user.

    In the another hand, the cons are these points that worse the experience, or the feature is not enough for fulfill what we expect from the device.

    Finally, the improvements pints are some features or specs that i think must be improved in a supposed new version of the device, and will generate a better experience in my opinion.

    Pros

    • Comfort is the most important feature of this device. Even with their size, the device feels good and bring an experience similar to using a game controller on the hands.
    • Analog Sticks are so good. They are so similar to X360 controller, and provide a good experience of usage.
    • This is the first device with full set of buttons, including C and Z buttons (part of the 6 button layout of the device).
    • DPAD is good and, in the case of the sample tested, accurate. Good for fighting games.
    • Main 4 Buttons are comfotable to use.
    • Shoulder buttons are so comfortables.
    • Touch Screen is responsive and appears to be good, considering is TFT.
    • Stock Firmware (official firmwares) run very smooth and are clean in general speaking.
    • Official firmware come with Joystick Driver for controls.
    • Official keymapper (stock firmware) include all controls of the device, this include C, Z, L3, R3, Select and Start
    • There exist a Custom Firmware based on Source Code of the device.
    • Speakers are located on front of the device.
    • There is a specific port charge for battery charging
    • HDMI output has no lag in general.
    • Materials are correct/good. Better than i expected for this device, considering the price.
    • The device come with a single camera and is located in front for videocalling, and i consider a good point this, because most of these kind of devices come with a low res camera (2MPx) located in back, and i don?t consider this camera as a serious camera for taking photos (resolution is not enough) but for videochat is ok.
    • System buttons and Select &amp; Start buttons are in front of the device (not in bottom side, as GPD-G5A)

    Cons

    • Not my case, but i see some cases where DPAD cannot do diagonals. As i know, this is a general issue of the firsts production batches, but the manufacturer will fix this in next batches.
    • There is no Bluetooth. In my opinion, is a must on these kind of devices. (headphones, controllers for desktop console mode, etc)
    • Based on G5A, main buttons are displaced some milimeters down, and sometimes is hard to press a button, when using right stick. I feel most comfortable using G5A device for this point.
    • Design is not easy to transport in a backpack or pocket. There is necessary to find a proper bag for keep and transport (and protect sticks!)
    • Is a very good point that manufacturer include 6 buttons in the layout, but the final layout is not comfortable as another layout.

    Improvements

    • Manufacturer tell to me that will fix the DPAD problem, but i will pust this as an improvement for the current version of the device.
    • Add bluetooth module. Is a must have for this kind of device (in my opinion)
    • Is not necessary but adding IPS panel may be fine.
    • Add a wist strap hole in the design.
    • Add real analogs to L2 and R2
    • KEEP the 6 button feature, but change the layout for something as i suggested, or other similar to 3x2 classic layout.
    • Add a USB HUB included on the same device (almost, one or two extra normal USB-OTG ports)

    • Buttons [4], [1], , [A], [3], [2]
    Might want to change those brackets to parentheses, or add spaces, as
    Code: [Select]
    [B]is interpreted as formatting code to switch to boldface.

    I bought these two thingies to go with my G7, hope they work to give me Bluetooth (still waiting on delivery):

    http://www.geekbuying.com/item/USB-2-0-BT-CSR4-0-Dongle-Plug---Play-318829.html

    http://www.geekbuying.com/item/Micro-USB-OTG-Cable-for-Samsung-Galaxy-9100-9200-9300-Micro-B-to-USB-A-313205.html


    Consider this USB Bluetooth dongle costs $4.79 USD (although they claim it's marked down from $9.15). I see internal Bluetooth adapter cards for desktops and laptops priced as low as $4, so I'm guessing a bare Bluetooth "antenna" (or whatever the component is called) built into a tablet would only increase the cost $2 - $3 per unit, tops. Seems like a real bone-headed cost-cutting move to leave it out.

    Even the cheapest sub-$70 cell phones have Bluetooth, to have this feature on a tablet (which you'd expect to have more features than a cheap phone) should be a no-brainer! Hopefully GPD addresses this issue along with improving the screen and controls for their next 7-inch gametab.

    About the Bluetooth... I believe there are no drivers included in the GPD G7 rom with stock or legacy.
    Also I asked skelton and he said that he will not be attempting because Bluetooth usb dongle support was removed in Android 4.2.2 and he would have to write a new blueZ stack.

    I've had my G7 for a few weeks, and I'm in agreement with most of the points of Deen0X's review. I also have a few ideas for improvements:

    The placement of the Start and Select buttons is pretty inconvenient for games that require frequent use of them. Perhaps they would be better off on the left side, in the space between the left analog and the D-pad.

    The shoulder buttons could also use some repositioning. They're not bad for occasional use, but if you're playing a game that makes frequent use of all 4 shoulder buttons, you'll want to have a finger placed over each of them. Unfortunately, this leaves your pinkie and ring fingers trying to support the weight of the devices themselves, stretched out to reach the handgrips because of the space between the grips and the shoulder buttons. I find when I'm playing a game (or just a section of a game) that doesn't use the shoulder buttons, my 4 fingers naturally want to stay together on the grips. So I think it would be better to have the shoulder buttons on the grips instead of the top, so the fingers can reach the buttons without having to move away from their natural position.

    I haven't found any use for the front-facing camera, as I don't do videochat or take many selfies. Having a higher resolution rear camera would open up the world of AR games and apps. Although there are not too many noteworthy AR games, this would still make more sense than a front camera on a gaming device.
