[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.

Oops. One off on the copy and paste:
http://forum.xda-developers.com/showpost.php?p=29759410&postcount=295

So this makes me wonder if the common issues could perhaps be with the back of the device. I've seen people with screen warping issues caused by a warped back, and now there's a fix for flickering by modifying the back.
I'm sort of curious to see what switching the back of a flawless device with a device with flickering does.
Edit: I also remember someone saying awhile back that they pushed on a certain part of their device to make the flickering disappear, which makes me even more curious if it's something to do with the back..
Another edit: The device would not flicker when the back was completely removed. Obviously, without the antenna, the signal was very weak, but the flickering would disappear. As soon as I placed the back on again, the flickering returned.

Only engineering theory is the antenna is moving the voltage for ground w/ the power surges when it uses full wifi power and this is affecting the ground level for the rest of the tablet including the backlight. By putting the tape there, you're preventing the wifi antenna from affecting ground level, though I don't understand why it doesn't affect wifi power (I'd think that by doing this, you're lowering the transmitting power of the wifi antenna).
Any other EE's confirm this might be what's happening?
Interesting workaround at least...it's basically a hardware version of the software workaround I theorized was possible if they could control the power transmission level of the wifi chip/antenna...

This fix makes the difference, its like night and day... thanks to the op

Not sure what you're talking about in "disconnecting ground," but the ground plane is pretty important for PFA antenna design. (I'm assuming that's what the N7 has, as there still isn't a good photo of the ants themselves in any of the teardowns.)
BTW, funny, but I made that very same antenna in your pic, along with the PVC pipe cover. Didn't work too well as an omni. I soon ditched the DIY route when I found surplus WISP ants to be much more effective, and less hassle.
BTW, a good read for wifi design is "Antenna Design for Mobile Devices (Wiley 2011)."

I'm going ahead and doing the same. It does look like modifying the back cover will fix the flickering issues, but after reading a bit on how the ground effects antenna performance, I'm a bit wary about it in the long term. It'd be one thing to just tighten a screw, but to disconnect a wire with a function isn't okay to me.

I've pasted some pages out of the abovementioned wifi design text on the effects of ground plane on mobile antennas. It's probably too technical for many, but you can get the gist, which is that the ground plane is a "big deal" in antenna performance.

Crackling Speaker Fix!!!:)

I've always been annoyed by the horrible noise coming form my speakers, so I did some experimenting and it worked here's how to do it:
1. Remove the back cover.
2. Remove the black fabric covering the faulty speaker(s).
3. Place a piece of electrical tape directly on the speaker.
This will very slightly lower the volume but it alleviates the racket made by the poorly made drivers. This may not work for everyone.
*I am not responsible for any damages done to your device. Attempt at your own risk!*
Good Luck!

I have that problem, but hardly seems worth voiding my warranty to fix it by ripping the back cover off.
All you gotta do is turn the volume down a notch and its fine...

You don't rip the back cover off. It's just held in place by some clips. There's no way anyone will be able to tell you took the back off if you doing correctly.

The back just snaps off almost as if they wanted you to. There's no way to tell that you did it.

Sorry, this sounds like a terrible idea. The speakers seem to only be popped over the coil, the real fix would prevent them from coming off of the base. I have reattached mine three times now but they eventually pop back up after some loud notification or such.
Better speakers would be nice, the n7's are just awful.

I fixed my speaker issues or at least reduced it so it's not too bad...
1) remove the back cover
2) now look at the speaker grill from the inside of the back cover. It is a small piece of metal plate with fine holes in it. This is only tack welded to the back cover in a few spots. There may be a couple of pieces of tape from the factory already holding the center section of the plate.
3) now use a few small strips of tape and hold down the rest of the plate at its edges...
4) resemble the nexus 7 and test it out...
The cracking sounds are not as noticeable anymore...
Ymmv....
I am also thinking about removing the little plate all together, or replacing it with a plastic mesh or some thin foam...

Manufacture defect in our screens? Internal Dip?

The day i got my Galaxy S4 i went straight to charge the device. I left it on my nightstand which is under a window and when i saw the reflection of my blinds through the screen, they where bent out of shape and the reflection looked distorted. Looking closer, the screen seems to have a circular dip in the middle left-ish area. All the devices I tested this do not have a distort. (iphone 5 and 4S, the SIII)
I'd like for everyone to look at there device and make sure they don't have this also. I cant check the devices over at carrier stores, abit busy sadly...
I've given a Sample of lines that u can use as a test and also left a quick video, ill try to make a better one but its all i could at this moment. Also its extremely hard to get it on a video vs what u see in person =/
http://www.youtube.com/watch?v=0Ej5VCPnKls
Best way's too test are as follows.
1) place your phone right in front of you on your computer desk and look at your Monitors reflection. It works extremely well when you look at Lines or a lot of text.
2) Look at a bunch of stuff that's well lit.

Man, I have exactly the same problem and the easiest way for me to see it is to have a reflection of a fluorescent tube on the black screen. It's ugly! This doesn't seem to be a universal thing, though, because this is the first post I have come across since I found out about the distortion problem. Did you find out anything at Bestbuy?

My first galaxy s4 had dead pixels, my second galaxy s4 had scuffing all over it, a large scratch on the MICRO sd card port, overheated and would constantly shut off, followed by the display that completely died a day later. Sprint advised me to give the HTC one a shot. As soon as I got the HTC one home, noticed paint run off, gaps between panels, dings, dents, pretty much the poorest quality control standards I have ever seen. Now I have to find away to get sprint to allow a FOURTH return on a 600.00 device. I may have to get mean, I dont like to act that way, but what sprint has put me through to obtain a working 600.00 high end device is not acceptable, I would not wish the experience I am going through on my worse enemy.
Im not picky, and I understand mistakes when they happen. But two damaged/defective S4's, and one damaged/defective HTC one in matter of 7 days? I really cant even believe it.
All I buy is Samsung products when it comes to electronics, never in my life have I EVER received two defective units in a row. I feel like a crazy crack addict every time I go back to the sprint store and request a replacement. If sprint didn't have a 14 day satisfaction guarantee, I would be out 600.00, because there is no way in a million years samsung or HTC would take responsibility for scuffing or damage to the body of the device. Even with sprints 14 day satisfaction guarantee, you are only allowed 1 device exchange. So basically, im entitled to nothing with this issue, and any day sprint is going to show me the door or refer me to Asurion for a 3 day old 600 dollar phone.

Razor sharp bottom edges!

Hey everyone,
I don't know how you usually hold your mobile phones but when I'm using it with one hand I tend to support the weight with my fingers at the back and keep my pinkie at the bottom...
Due to complaints about the speaker position on the Z, Sony have now moved the speaker to the bottom of the device, which is okay (except when you are playing a landscape game with both hands on device, lol).
But the main problem is that the speaker grill is not flush with the frame, leaving the rough aluminum edges exposed. My pinkie is suffering, lol. I reckon I can cut cheese with this thing!
Has anyone else noticed? Is your speaker grill in line with the frame? How do you hold your phone with one hand?
Sent from my C6603 using xda app-developers app

yup. this has been bothering me too. i'm having to adjust my holding habits and putting my pinkies on either corner to not make them sore.
on a similar note i'm having to re-adjust my holding position when playing a game or something in landscape. as one of my hands usually cover the speaker muffling the sound

Here's a picture of the killer edge. It's even shaped like a knife!

Lol, I'm obviously making it sound a bit more extreme that what it is, but it's definitely uncomfortable, I felt it was sharp at first but kept using it and after a while my pinkie started to feel numb and I could see the mark where the phone was sitting. So yeah, I am also trying to find new ways of holding it without dropping it, lol.
Keep in mind that the Z1 is also a little bit heavier than the Z...

Yep, those edges are quite sharp as well, but perhaps they are like that to help the magnetic charger clip on...
But I wish they had done the speaker grill flush with the frame =( like Google Nexus One had above the screen! Nice and smooth so it didn't hurt the users' ears!
I'm curious to know how you hold it though, do you grab it from the sides without supporting it from the bottom?

I usually hold it kinda like this but on my right hand and one of the fingers is exactly mapped on the magnetic charging port. I still can't see how you hate the bottom maybe yours isn't softened enough

Lucky you then!
I kinda got used to it by now, it's not like I've got a choice anyway unless I was to get another phone... But I've gotta say that coming from the XZ that bottom edge definitely feels a lot less comfortable, the way I hold it anyway.
I think it should be a rule for any aluminum phones that it's edges are sharpened out. It's on my wishlist for Z2 =)

[PSA] Your N5 May Turn Into a Gnex...

Mine did. Had it in my back pocket (stupid, I know, but I'm used to sticking my devices there), and next thing I knew, I had a bent n5 with backlight bleed galore. Seems this is a common problem with the iPhone, but unfortunately I expect to see more n5 users fall into my boat, as I was even being relatively careful to not put excessive weight on it while sitting (and I only weigh 160lb). Save yourself headaches and break any habits you have of putting things in your rear pockets now. :'(

No idea why someone would put their phone in their back pockets in the first place, to be honest. Seems common sense not to do that.

Your everyday carry can get out of hand fast.
5 inch phone, wallet, keys, pen,headphones, knife,flashlight Some of us may carry guns depending on the country, license status , or occupation. You can hit the need for a "man purse/satchel" very quickly. Sometimes your pants have bigger back pockets so that's where it ends up.

Every time I see someone stick their phone in their back pocket, I give them a bewildered look. Then they ask me why I'm looking at them like that, and I reply, "You actually keep your phone in your back pocket? How can you stand that?"
Goodness gracious, that has to be a chore to sit on, and I've seen a many stories where phones have been broken by being sat on.

Sounds like a human error OP, not a manufacturing error. Nothing to go creating a thread about. Most of us know sitting on your phone is not very smart....

Back in the day, I used to carry my personal Cell Phone on my hip in a case along with my pager for my work and my Palm Pre PDA. I looked like a real Techno Geek for sure. These days, I carry my work phone on my hip only. My PDA and my cell are now one and I carry that in my front pocket. Heck...I get nervous when I bend forward to tie my shoes. But...I live in Canada eh? and carry my cell in my jacket pocket or shirt pocket most of the time now. I've very aware of it at all times as I do not want an accident to happen. Putting it in my back pocket and sitting on it makes me twitch just thinking of it!

Yeah, I never understood the reasoning behind putting a phone in your back pocket. I was always amazed to see someone pull a phone out of their back pocket and see it still turn on.
Something I'd never do though. If needs be I'll just carry a bag, TBH.
