Anyone notice that the back cover of the Nexus S has two little gold contacts and some sort of grounding/antenna plane just like the Captivate?

And
http://pocketnow.com/html/portal/news/0000011184/backopen.jpg
Perhaps it's only a ground plane or something, but there is a striking resemblance. We already know our Captivates have a little something special (in the back cover mechanism and inclusion of an Audience voice processing chip) that none of the other Galaxy S variants carry. Just speculation, but maybe there's a NFC radio hiding somewhere in our devices and that "ground plane" is actually the antenna. Perhaps if someone can discover what exactly the NFC antenna looks like (if it's internal, or integrated into the back cover of the Nexus S) we could make a better guess.
Unless someone else has a more reasonable explanation?
well thats an interseting theory. kind of a stretch though, any number of things it can be. i mean because the nexus has two contact points and has nfc doesnt mean that the points are related to nfc. i think that the cappy not having nfc is evidence that the backplate is not used for nfc. but we may have un used hardware, if i knew more about antennas and nfc and things i guess i could draw a better conclusion.
i can tell you that the round point on the cappy goes to ground through a plating on the back of the plastic over. i made no attempt to trace the contact that is on the board. if someone with knowledge in the area of antennas could coment that would be great but it's probably nothing.
I've noticed this too.
If you tilt the back door at the right angle to the light, you can see a vague pattern (at least on mine) which looks like an RFID antenna in the recessed square on the back. Maybe it's something? RF is not my specialty, but it looks awfully like the pic on the left http://www.new-rfid-concept.com/rfid_and_nfc.html.

Noticed the pattern too. S'why I'm curious what it's for.
Huh, but why would they put an rfid chip in a phone when android is supposed to start using nfc? My guess as to the contact points are wifi antenna contacts. I noticed I get amazing wifi pickup from routers far away. Much better than any other device I've used. Although, no signals loose reception quality when the back plate is off, wifi, cell, gps. Idk. Haven't tried bt though.

Doubt it's an actual RFID in the back cover. It's just that little patch on the back cover looks very much looks like an antenna.
Really, I don't think it can be something. A mp3 player I owned for 4 years have something like this too. It's most likely to be something like digital ground just to keep the voltage stable...
Shammyh is correct, it is for NFC.

What are you saying? The captivate secretly has NFC? Seems a bit far fetched since found this yet. Would be cool though.

i know this thread is old, but i was searching for the same thing today. after i read this thread here, i found this, explaining some roms that support the chip:
"... Audience Chip support (Captivates have a special chip added that increases call quality... if it is used)." loraqu
@ http://forums.androidcentral.com/t-captivate/111137-cyanogenmod-7-vs-serendipity-vii.html
so i guess its like those weird sticker things they used to sell on tv that claimed "its like adding a 5 foot antenna to your phone!" and im assuming everyone knows by now it cant be nfc because the backplate is metal. i found it interesting, so there it is if anyones still searching.

Yes, I have a great idea. Let's have antennas put in the case of the phone, so we have to use crappy little leaf-spring type connectors just to have a connection to the phone. Then, to make it even better, let's have the case made of polycarbonate so it can bend. And to help with even better design, let's make the connectors so thin and crappy that bending them at all stresses them enough to make it not spring back up, and then trying to bend it back will likely snap the connectors. Because we need ideal antenna design, never mind the fact that an antenna is useless when it can't connect to the modem that needs it.
HTC has pulled this idiocy before, it happened with the Desire HD's GPS, it happened with the Sensation's WiFi and touch screen, now it's happening again. It is beyond me why they insist on doing this when Samsung is getting by perfectly fine by just having the antennas sit beneath the case. What happened to plastic being RF transparent? This is probably one of the few things that really riles me up about HTC, simply because they never seem to realize why the Galaxy S2 and S3 are more popular. When they can't even get basic antennas right, how do they expect people to be repeat customers?
EDIT: No, this doesn't affect the phone when everything is fine, but this can be part of the reason why there are wifi issues/general reception problems.
I'm sorry to hear about your experience, but it is probably just you or a software problem. I have played with many H1X's, including 2 of which are my own, and never had the problem you described. Perhaps you have a defective unit?

I don't own an H1X, I have a Desire HD but frequent multiple device forums.
Yes, you may not have a problem, but this design makes it incredibly easy to break Wifi/BT, and any other antennas that are connected to the phone in this manner.
Yes, if the connection breaks, it is a defective unit. My problem is that if you squeeze the back case often enough or have the phone overheat (likely if you have the Tegra 3 variant and use it as an in car GPS) then you will destroy the connection. Designs where the antennas are not in the case will never have this happen unless you somehow physically melt the connection between the antenna and motherboard or it is torn off, both are incredibly unlikely to happen.
It doesn't matter whether your phone has this issue, it is likely to happen and HTC needs to be pressured into changing their designs so this issue never crops up again.

I guess that explains why my first One X had no wifi (could never connect0 and it was that top left glass corner lifted up enough from the device that light came out of the crack.
But guess what? Got another while I wait on my warranty repair (no exchange because no stock).

The s2 and 3 are more popular not because of any of the reason you have stated.
But in case you're wondering despite HTC being abandoned by "expert" users aka xda members () HTC's customer satisfaction ranking has always been higher than Samsung. Google it.

There is no problem with the connectors, and as far as I can tell, touchscreen problems only exist when swapping batteries, and continuously chatting then in the phone. If you use an external charger and swap batteries, there is no problem. So its not the connector, but static buildup from continuously charging dead batteries. Yes it is a problembut goes away when using the phone as intended(charging just one battery per charge cycle).

The problem was the fact that the touchscreen grounding was on a spring that was supposed to touch the phone, and over time if you removed the back cover often enough it would start losing contact.
From the tear down pics there isn't much thats not built right onto the mobo. I have used many android phones, and really enjor the One X, I just think a lot of people don't give the device a chance. I mean I have had a few software issues, but nothing that makes me want to return the phone, it will all get fixed in time.

The problem is with the antenna connectors. I would not be so concerned if there was a ribbon cable or something that connected antennas to the motherboard, but I know that the type of design that they use is very easily broken.

Most every HTC phone nowadays has that antenna design; my Rezound also use spring connectors to the seperate backplate antennas. I have pits in my antennas from use, but no significant signal loss thanks to the rigid case design keeping the connections solid.
The relatively flexible case of the HOX really could interfere and needs a different connection method. The battery is non-removable, yet they just stuck with what they knew how to do anyway.

Probably because it's a working, effective design that has been implemented in almost every phone they make. No reason to change it. What's the term... "tried and true".
My old HTC Aria had the most flexible back cover ever, and the connection was fine after over 2 years of non stop service. I'm sure this phone won't have any issues, especially considering it is a unibody design.

I love reading someone's complaint about a phone only to realize further down in my reading that op doesn't even own the phone. Super fail lol.
On the other hand, my reception has been great. There is even this one crazy spot where I'd never get reception or data connectivity at work and now with this phone it actually works in said location! Love it.

I wish an "engineering" team built the one x, but they used a new "design" team because they wanted it to be stylish. Ponderous. Why worry about the back/shape of a phone when the majority puts it in a case and will never see or feel the back. Build quality should be the driving force, not design. Antennas should be HARD WIRED, period. All these pogo or spring style connectors have issues. I work with point to point wireless links and any connector has loss. 1db loss on a good connector. Spring and pogo are a bad idea and definitely causing too much loss.
I have an Inspire and TFPrime. Two big offenders. I have cleaned and retensioned all three on the inspire and it helped for about 3 mos, but GPS is getting flaky again. Going to HARD WIRE GPS antenna and be done with it. Basically what HTC should have done from the start.

The only way to guarantee all the functionality of your device is to use stock roms that where actually made for it. When you use ported roms that where never intended to run on your phone then you are not going to have optimized performance, it's just the way it is. There are only 2 gingerbread base for the inspire, so if you want the best out of your device, stick to those.
Your especially going to have issues when using a Rom like jellybean that isn't even a finished product yet. That's why it's in beta. And honestly Ics or jellybean will probably never run tip top since HTC will never release these versions for our devices.
One thing that a lot of people tend to miss. Check that the antenna contacts are clean and are making complete contact.
I did the wifi and GSM Antenna cleaning and bending the pins up.

anyone remember the Cheap Antenna Boosters that cost around $1 US. and it stuck on the back of the phone under the battery?
now I know 90% of them did not work. because the batter would block the Signal, or back them I had the Nextel with metal door and battery.
But I might take Cat5 wire. to build a fractal antenna to lay under the cover. I know there one on the door/cover now.

I'm curious to see your results with this. I had a booster on an old Samsung flip phone and it gave me another bar in most places. Heck, if it works you might be able to sell them on eBay.
Looks like this is just not such a prominent issue (but may be related to the 'headphone jack buzz') but here it is - even when positively connected, movement of the headphone connector causes the signal to either crackle or the headphones icon to disappear completely, as if I had removed the headphones. I initially thought that perhaps the 3.5mm jack I was using was not seating deep enough into the phone, but after taking the top cover off to make sure that was not the case, it seems to happen anyway.
Previous to this phone, I had an HTC EVO 4G, in which case some of those phones had a similar problem. There was a fix however, where you could dig into the phone a little and find a small copper flap that needed to be bent so that the connection between it and the plug itself was much more secure. Does such a surgery exist for the One S? I searched here but nothing much came up, except for the buzz issue with would seem to be more of an HTC screwup with grounding than something to do with the connection.

I am looking to replace my battery on my Nexus 6P, I've abused it in the form of basically charging it all the time, all 8 hours at work, it sat on the charger all day, since I use it heavily. I now know the erro of my ways and I want to repalce the battery.
I've watched videos on how to do it, I know it's not easy, but it is possible. Has anyone here changed it, also where did you get the battery, I've found them anywhere form $10 to $50, I ahve no problem paying more if I know it's an OEM battery.
Thanks in advance.
Maybe someone, but I've not heard of anybody doing it....
Not here either....seems like a terrible time haha Best of luck to you if you try but when my battery life degrades to that point I will be parting with this phone and either buying another one of some sort. Even working with electronics for years there no way I'd personally succeed the first time lol
I have dissassembled my phone to replace random components after falling on it. its not that hard to get apart in my opinion, and its super simple to replace the battery if you can source the battery

I've successfully done an internal component swap. Swapped the motherboard and battery from a very beat up N6P into one that was in excellent condition but was basically a paperweight.
The most difficult thing about this project was not getting into the phone, but getting into the phone without leaving any noticeable scratches. Removing the camera glass and the plastic strip at the bottom took at least half an hour of heating and gentle prying. Getting the screen out without a suction cup tool was a bit tricky too, i had to wedge in a chisel x-acto blade and pry it up, lucky no damage was done.
My advice would be to have on hand as many of the tools suggested in the youtube videos and to be patient while do it.

I've never taken mine apart but if I plan on replacing my battery I will buy the replacement glass piece and bottom plastic piece at the same time. Those are the only pieces that can get damaged in the process.
I just watched that video. from the looks of it, so long as you take your time. and have that suction cup tool, it should be fairly straight forward. at least you are not having to separate the screen itself from the guts to get inside.
Looks like my battery is on its way as well.
Anyone sourced genuine replacement yet?

Why?
I understand the 2 out of 10 rating on iFixit after replacing the back cover on my phone. 90% of the pain is getting to the 6 screws. I don't think it is possible without scratching up the old cover. Funny thing is that I just wanted to change it from silver to black. A heat gun is a definite requirement. Not for the faint at heart for sure.
