[Nexus 7 (2013) General] Gorgtech:
Warning: These MODs will void your warranty. You will have to open the device and leave traces behind by performing them. Only perform these Mods on your own risk, if your tablet turns into a brick after or tries to conquer the world, it is not my fault !

As many people know, the Nexus 7 ( 2013 ) has some serious issues. Some devices might show next to no problems at all while others are barely usable.

The Mods I´ve come up with help to at least make the tablet usable again since the manufacturer saved too much $$$ for these devices.

Improving the Touchscreen performance and fixing the grounding issue:

The Touchscreen controler is way too sensitive and the connector cable leading to the Touchscreen acts like a antenna. In order to suppress interferences, it requires a shielding.

I know that some people try to flash other Firmware in order to improve the response but this is not how you can get rid of the problem permanently. These extra Touchscreen Firmwares might decrease the sensitivity and make the Touchscreen usable, not more or less.

Material needed:

- Some Aluminum Foil

- Some adhesive Tape

- Some thick piece of paper ( optional )

- a multimeter device ( optional )

- conductive pads ( optional )

Basically you need to disconnect the Touchscreen connector, attach some thick piece of paper between the cable and the battery ( only optional since this method only adds some extra insulation and insures a even tighter fit of the cable ), attach some Aluminum Foil ( make sure to fold it many times since you need many layers to make it stable ), wrap it around the cable and fix it with stripes of adhesive tape.

This is how your new cable could look like. The open copper spots on the Touchscreen cable are connected to ground; by attaching the aluminum foil, it will also have a connection to ground and shield the cable against interferences. You can check the proper connection with a multimeter if you´re not sure if you have a tight connection.

I also attached a extra conductive pad on top of the connector to ensure a even tighter electrical connection.

I salvaged these conductive pads from junk devices :D

After having performed this Mod, I never ever had any trouble with my Touchscreen controler going ape-sh*t after a while or not reacting when the tablet was laying on my table and only being touched with one hand only ( also known to other people as the "grounding issue" where you need to touch your Tablet with both hands ).

Audio buzzing issue:

My device also had another issue where I could hear a buzzing noise while using the headphone jack without playing any sounds at all. I could only fix this ground connection issue by bypassing it with a extra trace of conductive ink.

Material needed:

- conductive silver ink

- conductive pads

- adhesive tape ( optional )

This is what I did:

You will need a multimeter to check if the connections are ok and also attach some extra conducting pads.

Safety first:

If you´re too scared about risking a short circuit, you can attach some adhesive tape :

My device is working without any flaws now and I can finally enjoy it like I wanted it to behave when I bought it in 2013..

Happy Modding,
