[fix] An easy way to solve the screen flicker with just a scotch tape

---

Hey guys,I'm a nexus 7 user from China.
I have solved the screen flicker problem.
Just put a piece of scotch tape on the GND point of WIFI antenna.It does not influence the signal strength.

Not gonna do that. By not connecting a ground you could run into some other serious problems later on. Excessive WiFi chip heat and possibly other issues

Won't be.I have studied the wifi antenna for several years.Wifi antenna has many types,some of them like omnidirectional antenna,it‘s RF line and GND is not connected.

I've just done this. So far, wifi strength fine and there is definitely less flicker.

However, this its light outside and it's much easier to see the flicker when it's dark, so I'll let you know.

Thanks for the idea, and hopefully this works!

I'd definitely this if I was more confident in opening my device

Watching with interest, before I go through and attempt it.

may i ask what is your theory why this works? In simple terms! If I could sort the flickering I'd be v happy. Thanks

Confirmed as working on my device. It completely eradicated the flicker too, which is awesome.

I also would love an explanation as to why it works!

I cant really tell by the pic, is that just a piece of clear scotch tape taped over that metal part? Its not in between or anyway special right?

Does anyone have any information on why this works and if there is any possibility of it messing up the tablet?

Just slide your finger or thumb nail between the top edge and the back on one corner then slide it to the other top corner and the back will start popping right off, it's very simple.
