GPD G7 Fixing/Improving DPAD
« on: February 24, 2014, 09:00:45 am »
On the GPD G7 I received the DPAD was not performing property. Diagonals were very difficult to press.

To fix it I made the dpad internally a bit more rigid by placing a piece of material under it. I used cardboard but I think something more digid would be better.

Now it is much more responsive and diagonals work.

By the way. I find the internal constuction rather solid. There are a lot of screws to fix the different parts and back reinforcements so I dont expect the buttons/sticks or dpad to break if heavily pressed.

Opened device


Removed dpad


Mark drill possitions


Trim that and assemble back


Reinforcement details


Bonus: Where rumble was supposed to go

Thank you for taking more pictures of the inside and showing how to fix the d'pad.

P.s.
Could one perhaps solder the rumble motors in and use them, or are the software drivers completely missing from the device...

I will definetelty have to do this mod. Or  similar one. Got mine today and dpad is quite unusable as it is. Very hard to make diagonals, so very difficult to play fighting games. Specially the down-left diagonal is almost impossible to do.

It's a pity, because device is fine, and with a normal dpad like g5a would be better, but dpad is very poor, at least in my device.

I am not dissapointed anyway, since my main use for this device is development and just some android games, but for emulators it clearly needs a better dpad.

If anyone opens theirs would it be possible to take a picture of the Dpad to show the shape? Seeing as it's based on an XBox360 Dpad it would be interesting to see if the replacement ones will fit:

Interesting that these are so different to the G5A, I thought they would use the same parts. I can do hadoukens and dragon punches no problem with the G5A.

The dpad/buttons/sticks look quite easy to get to, but after the six screws are out on the left and right side does the device just snap in place in the center?, Id be afraid that I would break the case trying to wedge it apart.

Also would a xbox 360 dpad rubber(what ever its called) be better to use than the clear one in the pictures?

Remove the ribbons first to operate comfortably.

The biggest danger I noticed is the board that has the shoulder buttons and analog because it has a 90 degree soldered board.

There is one screw on the dpad that is a bit under that board so you have to lift it a bit. Be careful not to break the soldering.

About materials. I would experiment a bit. My idea was to create some extra rigidity. Maybe it would be better just to increase the overal pressure by making the under part of the dpad thicker.
