Captivate and Nexus S back cover similarity (maybe NFC?) - Captivate General

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.

UPDATED!: Pictures of Captivate Mainboard

So.. after some tinkering (and massaging) I got the back cover off of my Captivate and was able to snap some pics of the innards for your viewing pleasure.
It's very similar to the standard Galaxy S, but some of the chips are laid out a bit differently, also, I apologize for the substandard picture quality, the only thing I have available to take pictures is a Blackberry Storm2 with an led flash.
Update: I've taken some better pictures now, and I've got them uploaded:
Teardown Photos
Enjoy!
Update:
Step by Step Teardown
Very cool
That is cool. Wonder how long it will be until we see a complete tear down of the phone
That is (almost) as far as you can go. Theres one more PCB thats actually attached to the screen. Other than that, that main board and the sim/sd card board that sits on top of it are all thats there.
Edit: Here are some better pictures I was able to take this morning, unfortunately EVERY single picture I tried to take of the small Broadcom chip turned out like crap, or you could not see the writing on the chip. I could not read it myself, as the writing on the chip is extremely tiny, and I don't have a magnifying glass.
Teardown Photos
Any way you could do a photo-by-photo instruction for the tear-down? Maybe put some o' dem fancy photo-ma-shop arrows in there?
I suppose I could do that
I just need a few more photos of the "in between" steps to give a better idea of what needs to be disconnected and how to get the back cover off.
And then there's the whole write up thing. -- Question about that, should I do a new "tear down" thread, I'll get a bit more in depth this time as well, I'll get all the chip numbers down (I found a magnifying glass!) so we can better cross reference what hardware we have in comparison to the Galaxy S i9000.
Will probably be a day or two until I can get it up, maybe longer depending on the write up.
Yeah, I'm guessing a tear-down thread would be in order unless there's some way of changing your thread title. Appreciate it.
I spilled a bit of an "adult beverage" on my Captivate last nite. Dang cat... Nothing went wrong w/the phone... save for the power button & the volume rocker... They were a bit... sticky.
I was able to get them cleaned up a bit using a razor blade & some alcohol wipes, but I'd love to be able to fully clean everything by disassembling the phone. I removed the 4 screws in the back beneath the battery cover, but got nowhere...
Can someone confirm if the fm radio chip is there?

Thats one of the purposes of tearing the phone down, I'm hoping to answer that question, or at least give enough people enough information to find out.
https://fjallfoss.fcc.gov/oetcf/eas...me=N&application_id=200666&fcc_id='A3LSGHI897'
pretty cool u think now that we can tear it down, we can add the front camera too it?
I don't know, it would definitely take someone much more skilled than I to fit the Front camera in.
The layout on the top is a tiny bit different, and it would require some changes to that as well as making space above the screen on the opposite side for the camera.
So, definitely NOT an easy job, if it is even possible.
if you look at that video of the teardown of a galaxy S i9000, it looks like the FFC is part of the rear facing camera module
http://www.youtube.com/watch?v=lt9XNnjAcBc&feature=player_embedded
at 2:59 in the video the camera is taken out, and at 3:07 she turns it over and you can see the front facing camera - does your rear facing camera look different (except for the obvious, missing that small black square with the FFC)?
if it's not different, except for the missing ft camera, i suspect these are all modular components so sammy could assemble them, as needed, to a customer's specs - which means, if someone can source that correct module w/ffc, and rip the driver and software for it from the i9000, that it'd be possible
The camera is identical, minutes the front facing piece, if course. The connection to the main board is the same as well.

if you pull it apart again, it'd be nice if you had a magnifier or a camera capable of macro shots so we can definitively identify that gps chipset
The macro on my camera is good, but not that good =)
My magnifying glass, however, shows me that the chip is a BCM4751.

My research shows that this chip does not do anything with FM radio so that is quite disappointing. Dammit AT&T! Always got gotta crap up a great phone. So now we don't get FM radio and we don't get the FFC.
if its the same camera module minus the FFC, im sure we will find some junk galaxys on ebay for parts soon enough, sum1 will develop a new front for us hopefully, pop in the new camera, get the ROM for it to work, and hope it can work. i am by no way an engineer or anything technically, so im not saying its plausable, just saying it could work if some1 knew how to do it.

tks - it may be sammy did use a different gps chipset in the captivate
and btw, macro will magnify - take a high res shot, then open on your pc, depending on how hi res, i've had them open the picture in 25 X 22" or so sizes
and you can see mosquito footprints - had an Omega, a high end one that had a serial number on the backside way too small to read even with a 6X magnifier - had to have been laser etched
used a macro shot to read it - no joke

[REQ] Hadrware GPS Fix

This hardware fix was posted in the Vibrant, General forum. Can it be implemented on the Captivate?
http://forum.xda-developers.com/showthread.php?t=878970
I actually think this was done and posted in the dev section. I'm gonna check real quick and post the link, but our GPS contact is just under the battery cover, no need to disassemble the phone.
http://forum.xda-developers.com/showthread.php?t=876179
It was in the general section.
So it's a hardware and software issue.
Clearly Samsung is never going to fix this, the design is bad. This is crazy to use this type of contact on an antenna. Let alone on a removable back cover. Especially at these frequencies.
I can't believe Google let them get away with it using pretty much the same design for the Nexus S.
This will definitely be my last Samsung. Well, after I have AT&T replace it to fix the turn off problem...

Wrong! My phone works as it is...!!! Samsung fixed it!
I returned my phone since it was having sleep death issues. They issued me a refurbished phone of 10.07 batch since it was within warranty. I had a GPS lock within 10 seconds even on the supplied stock 2.1 JH7.
Check for later batches of phone, or keep exchanging till u get the working one. The initially released batches were flawed.
You don't need to disassemble the Captivate to do this fix, because the antenna contact (or antenna ground contact) is exposed under the battery cover. There's a thread covering this in general.

Ugh. Whatever. This is a design defect similar to the iPhone 4's stupid antenna placement. Samsung at least had the sense not to use this lousy contact mechanism for their cell antenna. If they did they'd have sold about 10 of them before word got out that it drops calls constantly.
This type of contact for this range of RF can not work reliably - period. (I realize I may have a different sense of reliably than you. Reliable is far more than 90% of the time ...)

[Q] Where is the GPS Antenna ? (Interesting case issues!)

I was rather disappointed in the GPS performance of my shiny new Desire S...
It was so erratic, I loaded GPS Test app to check out the signal-to-noise ratio.
Then, just out of curiosity I took the aftermarket outer case that I had bought (rubber+plastic) off.
The GPS signal increased dramatically and many more satellites appeared. This effect IS consistent.
I was thinking of modifying the case by cutting a hole in it to improve GPS reception, but I'm not sure where the GPS antenna is located.
I know that phone and WiFi antennas are in the battery cover, but I would suspect that the GPS antenna probably is not.
Anyone know where it is positioned ?
Thanks,
- Steve
Not sure about the Desire S, but I had Legend before and the GPS antenna was behind the camera cover. It was connected to the plastic cover in a similar way the WiFi/phone antenna connects to the battery cover using small metallic terminals. I used elimination to determine which was the GPS.
Interestingly enough, I do not suffer from poor or erratic GPS performance on the Desire S. I get quick fixes from plenty of satellites even in less than ideal conditions, eg, a moving subway train.
Slightly off topic, what I did notice though (using GPS Test) that even with 12 strong satellites, the highest accuracy ever achievable on the Desire S is 9 feet, whereas every other HTC phone I've tried (Legend, and even the very budget Tattoo) goes down to 6 feet accuracy. Wonder why that is?
Oh, maybe it is build into the cover, then. I'm used to seeing ceramic block GPS antennas which never look thin enough to be built into a battery cover.
At least my GPS works quite well too until I add the flexible case on.
I was annoyed that the case attenuates the signal, because it was a particularly expensive and otherwise beautifully made one.
If nobody knows where the antenna is, I might have to do some experiments too.
As for the ultimate accuracy of 9 or 6 feet.. Well I suspect that it's just a subtle difference in the firmware. I don't believe that kind of accuracy is reliably achieveable anyway unless you use Differential GPS techniques - And I presume Qualcomm doesn't add that kind of luxury to their phone chipsets.
- Steve
An update :
I got a GPS lock, and observed satellite signals using GPS Test.
Then I put the DS into airplane mode so no radios were active to mess things up.
Covering the lower part of the case all over (including battery cover and screen) with foil has NO EFFECT.
Covering the upper part of the case around the speaker causes GPS signals to fade away.
The hard plastic cover supplied with my case kit has NO EFFECT.
As soon as I apply the rubber part of the case kit to the upper part of the DS, the GPS signal fades.
Conclusion:
The GPS antenna must be in the upper part of the case
It's the rubber part of my case kit that reduces the GPS signal.
Hope this is if interest!

So the GPS suffers from the death touch as well like the wifi since the antenna is at the same place.

erm.. I thought that the WiFi antenna was in the battery hatch with all the others ?
I reckon that the GPS antenna is probably the other end of the phone up near the camera lens. I've never had a problem with it being obstructed by hand, only by my damn expensive case!
Wifi antenna is at the top too but i thought people already knew this from the famous wifi death touch/grip?

I'm so sorry to hear about your problem.
I have many years of experience with different types of GPS and although the DS is not the best I have ever seen, it is not too bad (without the extra case, that is!) Only dedicated GPS units like SIRFstar seem to beat it, and that is understandable.
Do you only get about 4 satellites with the DS out in the open air with no buildings around? It can not work well indoors or sometimes if there are large buildings around.
Have you tried using "GPS Test" or a similar application to clear the AGPS data then load it fresh again?
If all else fails, perhaps your DS is faulty?

Thank you so much for help me
I tried everything i can do i checked outside and on my house. i used gps test, gps stattus, gps-fix. And still problem
I think my DS is faulty. so sad.
My friend have one, and it work better.
An update :
I emailed the manufacturers of my rather expensive case explaining the problem.
They seem to have a good customer service department - I got a speedy reply but they claimed that they were not aware of any issues with cases affecting GPS reception. They say that all their cases are made from the same materials so they would have thought that if there was a problem, it would affect other phones too.
They have promised to pass my information to their engineers - I hope they might get in touch with me!
In the meanwhile, if I can find out precisely where the GPS antenna is on the DS, I might try cutting a gap in the rubber for it. I'm sure that would help.

I use a Case Mate Barely There Case and it doesn't affect GPS, wifi or phone as far as I can tell.
Rick Ohlendorf
I use the Case Mate Barely There Case too, but I doesaffect the GPS for me.
When the case is on, getting a location lock in Navigation is impossible.
When I take it off, I get a lock within seconds.
if you look at the back of ds, upper portion there is 2 small holes, ive always thought that its a hole for wifi and gps. one hole below the flash led, another on right side of speaker.
then on my capdase alumor case, it also has a hole for those 2 hole, so it might confirm my theory that those are antenna holes thats why capdase also made holes for them.
I use a case-mate tough case, a much thicker dual layer heavy duty case, and I get a gps lock just fine with it on.

I would like to extend the GPS antenna.. I just can't open the cover, how to do? I only managed to scratch it a little..
I have no case,but the signal is very bad.I turn on airplane mode and GPS,it often takes half an hour to get my location...
Best accuracy is about 5 meters.
The cover needs a stick.HTC used some glue.

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.

The s2 and 3 are more popular not because of any of the reason you have stated.

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.

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.

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.

[Q] Headphone/aux jack sad trombone

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.

Very nice, allready thought only I had the problem :-x
Gonna send my phone to HTC soon anyway, lets see if they can fix it...
It burns me that stuff like this, which I would consider very important, never seems to come out in the 40 or so 'FIRST REVIEW's all over the web when the device is handed out to reviewers.

We'll, the phone has been out for months and this is the first I've heard of this. I've had problems with some super cheap headphones, but reasonably quality jacks always work. Don't extrapolate from small samples.

I'm pretty sure manufacturers try hard to cherry pick the best of the bunch when sending out review units. Look at reviews for the lg g2x. Look how that turned out when consumers finally got their hands on it

You call Sennheiser-Headphones cheap ?
I tested 6 different ones and the problem persists on all of them
