Lol I asked the same quesion when I had my evo. I believe these are for antenas for when the phone was being tested. You can hook up some antenas same you hook up antenas to a laptop wifi card.
Yep antena hook ups, don't try and use them though, I've heard of people not getting signal back after trying an extention.

I recently was looking for ways to increase my T-Mobile Dash's reception. I found a cheap and easy way to make an external antenna out of copper wire.
It worked, but now every time I remove the antenna, I have no service.
Did I ruined my phone permanently?
Is their an easy fix?
How do I re-enable the internal antenna?
Thanks Svoms
ummm just wondering where did you stick the copper antenna.

Dude! It clearly states that its for an emergency situation when your phone's life isnt a priority. Im thinking you jacked your phone up! You might be able to buy some replaceable parts, thats prob your best shot. Bummer dude.
you do realize if you did what demonstrated....you could have fried your phone.
You do know you create static electricity?? Since the copper wire was not rubber coated, ZAP!!!!
Shame on him for not telling people to cover it with tape, wax, whatever.....LOL
Make an emergency light ...
... using only an over-head power cable, a piece of bare copper wire and a gullible human being.
Don't ...
... under any circumstances do the above.
No.
Really, don't.
It will really, really hurt and you cant even finish the crossword by the light emitted anyway.
Don't do it ...
Step away from the pylon ...
Lol I see, so my question is why did you do that?
Let me tell ya I look badass with a wire hanging out of my phone..
Well thanks for trying to help..I'm getting a new phone soon anyways.

Well thats good to hear but dont do the same thing ever again okay.
anybody know what the pins on the back of the battery cover are for? it looks like what you would find on a phone capable of inductive charging. if so, anybody figure out how to do it?
They act as an antenna, dont **** with them
hmm ok. ill have to try it with the cover off to see its actually the antenna but ill take your word for now.

it does when i was playing with my phone without the backcase on i had no service
I only get 2G service when the back cover is off. I think it has something to do with the antenna as well.
I actually was wondering what the pins were for. I just took my back cover off and immediately dropped all signal.
thats kinda weird to have an antenna in the back cover. maybe they plan to release a new back cover that will improve strength? i cant seem to understand why.
Its just the design. And it saves space on the device.

Its definitely the antenna... and i personally think it was a brilliant design!

inductive charging would be great for our phones, i know the palms do it!
So anyone want to do the palm pre inductive charging hack. I think it has been done on a hd2

HTC states that the battery cover of the aria is the antenna on their website under troubleshooting:
My device shows “No Service” but I know that there is coverage at my location. close
The antenna for this device is embedded in the battery cover. If the battery cover is not installed correctly, securely affixed, or if it has been damaged, this could be the cause of the device not picking up on a signal.
You can find this on www(dot)htc(dot)com/us/support/aria-att/help/phone

lol, it tells it's an antenna in the manual, I know, I'm like, the one guy that still reads those...
yesterday i dropped my DHD, and i realized the wifi stop working. when i turn on the wifi at settings, it just said "error", and wont detect mac address.
thingkng it just rom acting abnormally, i just reflashed over, aaand.. it still the same. so i factory reset, and it still the same. so i came with a conclusion that the wifi hardware must be broken, so i gave a try to 'knock' it and it works!
so after a small knock again my wifi dead again..
i wonder if it possible to nudge the wifi module, but i dont know where the module located,
the service centre said, they had to replace the main board and cost $145, duh!
anybody had tried to work with wifi antenae?
happened to me two days ago
Check to make sure your battery cover is on properly and not loose. I'm pretty sure that is the wifi antenna.

i'm not sure the battery cap has anything to do with this, but i'm pretty sure the battery cap was snap properly.
yeah, i hope someone had the clue how to nudge the antena,
The wifi antenna sits in the battery door, it's the little metal clip you can see in the door when taking out the battery.
You can try to fix yours if it's broken, or buy a new one on Ebay.
Hope it helped.

It happened the same to me, I repalced the battery cover and still no WIFI.
I tried using an APK named "FXR WIFI Fix and rescue" it fixed it, but after a day it was unable to connect again.
Looks like it's time to change my dear DHD
Duh, is it so hard to try for yourselves before giving an useless advice?
I just tried wifi with removed battery cover and it's scanning without giving any error.
gampangingats, if you are using Sabsa, it's still possible that this is a ROM issue, happened to me a couple of times, but system restart (full) always fixed it.
Right. This is a royal mess here, with everyone giving different ideas.
First ensure that both covers (battery door & bottom SIM/SD Card cover).
Then try a rock stable ROM (BlackICE, or something CM7 based is always good)
Then try the rooted stock ROM (search for it, its here somewhere)
Report back once you've done all that..
If not, go to the Ace Think Tank (in my signature) and post there. Resident HW expert Glevitan can help you out)
after dropping my phone it was fine for a while (got a couple phone calls) and then it lost connection to the network. t-mobile troubleshot and couldnt help. i can use wifi calling fine everything else works (except screen is cracked and black - to troubleshoot i opened up my phone and gf's phone and plugged her screen into my phone) but i got a circle with a line thru it in the status bar. no data, no bars.
what broke (besides the god forsaken screen - see other post on that: http://forum.xda-developers.com/showthread.php?t=2112328)?
i've factory reset the phone and opened it up, poked around, unplugged/replugged the antenna.
Have you tried odining back to stock?

Lol it is stock
Maybe your antennae disconnected from the board.
I can't use WiFi on my g2 after my gf dropped it.
Figured the WiFi antennae disconnected from the board.
A solder gun could fix it.
Or sending it to Samsung

Doesnt help you voided both of yours and your gf phone by opening them up. Something internally broke im guessing.

warranty? lol i voided my warranty when i shattered my phone on the concrete.
sim card has been in and out several times. no sim card error, and as stated, wifi calling would not work if it was a sim card issue. sim card works fine in another phone.
as i said i unplugged and replugged the antenna (the long wire that goes from the the lower right to the upper right along the edge of the case when looking from the back.)
does anyone know what PRECISELY this is what it does? is this just the radio antenna for calls and data? is the wifi a separate component? and how else might this part have failed? the solder joints look good. i dont think the gf wants me removing her antenna to try it out and of course i would hate to damage her phone.
it really does seem like it's just an antenna issue...
Does anyone think that there is any possibility that having the rear panel removed (not the very outside cover but under that, the one that has screws) has any impact on the phone's ability to connect? there are a few little metal contact points on the plastic panel that touch contact points on the board. what do these do?
so i just a got a used s3, probably launch model. very happy with it. only problem is the signal. no matter where i am, as soon as i use the data, it instant drop to zero bars, 100-125 dbm making data unusable.
I've tried troubleshooting it by disconnecting the antenna cable and saw that it made no difference. I would think that if you removed the antenna cable, you would either get no signal or bad. could it be i have a bad antenna cable or the connector on motherboard? or is that the wifi antenna?
any more way to narrow it down or is it a s3/sprint issue etc
Thanks

No I get fine signal so its not a known issue across all s3 but u might have removed the WiFi cable if your signal didn't stop I would suggest trying to use odin to restore to stock again maybe the build your running has issues if that doesnt work i would suggest take it to sprint and show them the issue if they can repair it its free if not they order u a replacement for $30

Doesn't matter if u have TEP if for any reason you need a replacement phone while your still in contract and your phone is activated and is not physically damage or water damage then u can get a replacement for $30 unless your screen is cracked which is of course more ive done that with several devices in the past
