Where is the Galaxy Note Antenna located? - AT&T Samsung Galaxy Note I717

I've heard the Galaxy Note i717's antenna is integrated into the BACK BATTERY COVER. But I've also seen parts on eBay that indicate the antenna is located in the the bottom of the phone where the speaker is. Can somebody verify this for me by taking off their back cover and making a call?
I am asking these question because I can't get network on my phone with or without the battery cover. Which probably means antenna is near the speaker part. But can somebody still verify? Thanks
Thanks.

The only thing on the battery cover is the nfc.

As stated before, the only thing part of the AT&T cover is NFC.

Did you really have to start a new thread to answer a question on another thread? Someone had already answered the question on the other thread and said it was the NFC antenna.

There are 3 antennas, 2 on the top edge, 1 on the bottom. Not sure which is for cell, wifi and gps. Plus the nfc antenna on the back cover.

Here you go.

Ah, forgot about that 2nd LTE antenna. So 5 total including the NFC antenna.

can someone post a picture and explain to me what all the metal parts and pices attached on the battery cover of the amaze is for and what each does???? I know one is for antanae but the rest I have no idea and what is the purpose of these things?
it you could it would be awesome appreciate it.
Not sure of them all but the one on the top right is the wifi antenna, i assume the one on the left is the NFC antenna, the rest id also like to know

I am with you...When i took mine apart, it scare me. All those connectors to mme seem that it would make your phone susceptible to be easily broken. I hope not, but it is definitely intimidating...

Wow, really?
There are contacts for antennas, noise cancellation and NFC. why is it you need someone to provide you with the minutia?
It's not that hard if one have a need to find out - I don't personally.
If you cut a little piece of thin plastic and put in between those contact point you'll be able to find out - at least with phone signal, bluetooth, wifi and gps ...
BTW hopes you post pictures and explain too

Wow, really? That was a less than helpful post. What was the point? He asked his quesion in the proper thread. He waited several days for a response before bumping. Does his reason for wanting the info matter to you?
@seansk. The only info I can give you is that the contacts to the right of the camera opening is for wifi. Other than that I don't know either.
I signed up just to put this in. I think the connectors on the bottom of the battery cover are for the phone's cellular antenna. Long story short, I put some foil over those connectors thinking it might give me better cell signal and I actually got worse signal. Took off the foil and voila, signal came back to normal strength.

HTC EVO 4G LTE Wifi issues Similar to HTC ONE X Hardware

Hi all. This is my first post and would like to thank the many posters and helpful threads I've read while going through my many previous phones.
After hours and hours of trying to figure out why I've been having Wifi issues, I came across a thread on XDA that helped me find a couple of simple fixes. I had to rule out the issue being with my Wifi router since all of my other electronic devices that used Wifi all worked. It had to be the phone. That and the latest software update never fixed the issue.
http://forum.xda-developers.com/showthread.php?t=1688538
First off, a big Thank You to "bigoliver" across the pond who posted the :"Hardware Fault, Wifi Antenna Fault" thread in the HTC One X forum. I'll thank him here since I could not find the "thank you" button on the thread. Sorry, still a newbie.
Anyhow, after reading the thread and follwing the many helpful links in the post, I figure the probelm could be the same seeing how the Sprint version was not that mcuh different other than the Sprint only changes.
http://www.youtube.com/watch?v=b-QrMgSvna4
After performing the "squeeze test" as noted in the One X thread and Youtube video above, I noticed the same issue with the EVO LTE. Seems like the springs for the Wifi and BT antennas were good or enough contact with the antenna on the inside of the back case. This can be done with the Wifi Analyxer app. by simply putting pressure on the screen and back cover between the camera and volume rockers, you would notice the Wifi signal increase or decrease as your remove pressure in that area. This is where the antenna springs make conact with the antenna just inside the back cover.
The few video's I found on Youtube showed a few ways to fix the issue. One was having to solder a few contact to the Wifi and BT antenna springs. This seemed a bit dangerous since the user had to take apart the screen to get access to the spring location and back cover. Seeing how the Sprint version had the simple back cover that allowed access to the antenna springs, I figured I give it a try without soldering.
http://www.techrepublic.com/photos/...=11&tag=siu-container;thumbnail-view-selector
The picture above shows the EVO LTE front facing down with teh back cover off. With the phone facing down, you will see the two antenna springs pointing to the left by the volume rockers and just above the kickstand. If you look at the inside of the back cover, you will see the yellow antennas. If you align the cover as if your were putting the cover back, you will see the two antenna contact points. This is where the Wifi and BT antenna contacts are found.
All that I had to do was pretty simple. I took a tiny flat head screw driver to gently lift the two antenna springs up. Just enough to give a better contact to the antenna with the cover closed.
Once the back cover was back in place, the Wifi analyzer showed the Wifi signal to immediately increase. The Wifi signal was as strong if not stronger that my previous Evo 3D. I even noticed Wifi hot spots around me that I never saw before. This also helped the BT seing how the antennas are located at the same spot.
http://www.youtube.com/watch?v=OsUs2IVEU-c
The other simple fix I found above seemed a bit tacky but worked. The user placed a small coin underneath the phone cover in the area where the the springs contacted the antenna on the back cover. I tried this also and it worked. Just didn't dig the sight of the coin beneath the cover.
Seeing how this helped my Wifi issue, I figured it would help others having the same issues.
After reading the posting rules, I'd looked for a simliar thread before I posted. All other the Evo 4G LTE forum all listed questions but not a fix.
Hope this is helpful to some one.
Thanks.
Interesting fix with the coin method.
We talked about it here briefly, but the results were not consistent:
http://forum.xda-developers.com/showthread.php?t=1710905
I tied this. Saw 4 pairs of contacts. One pair had a contact sitting very low. No way it was making good contact with cover. My WiFi has not been a problem - it was the bluetooth device. Hopefully this will help.

Seems like the architecture is slightly different with the EVO as this hasn't been an issue that I know of. This seems specific to a faulty cell you have but thanks for the write up and details.

I've had issues on both stock and aosp roms with Wi-Fi connections bouncing up and down. I'll have to give this a try, thanks!
Be extremely careful when bending the antenna springs because it's very easy to break them.

still dont think this is an issue with our phones tbh...if it is, its unrelated to the OneX ones....hardware/shell's are different b/w the two....
regardless if you show it somehow.....take the crap in and swap the thing out!
So sick of watching WiFi come and go.. I'm rooted and with " WiFi fix " in the Rom I flash still same crap to point I just want my good ole og EVO back what a good solid phone that was

If you need to put a coin in your cell, you should probably take it back for warranty replacement as that doesn't seem to be the norm, honestly. Just my opinion, either way, glad that worked for the time being.

An alternative solution would be to put a piece of cardboard, just anything to keep it propped up. I advise against making it too thick though, it still needs room to flex.
Sent from my Inspire 4G using Tapatalk 2
Using a coin could potentially be bad. I'd use a piece of paper or cardboard myself. Shorting out a circuit in your phone could cause more issues. I'm saying this because the coin is going to touch more than just antennas simply from its size compared to the phone internals.

Am pretty sure it is the two contacts at the top of the phone under the battey cover, If you are having problems make sure the contacts on the handset are prominent enough to make a good connection with the rear casing, Be careful not to snap them if they need bending etc.

Thank You, I am trying it
Wifi/Bluetooth antennas tend to be at the top or the sides of a phone. With the actual cellular antenna being at the bottom.
FCC requires all mobile phones to have the cellular antenna farthest from the users head (health concerns). LTE being the strange exception mostly being near the top or the side.

[Q] Question about i777 charging port replacement

I have a very specific question with regards to replacing the charging port on the i777. I have searched threads discussing charging port replacement, but was unable to find anything about this specific issue. I am currently going through my first repair on my i777 that needs a new charging port. I bought the replacement on ebay, but something stood out once I compared it to the original charging port I took out. On the original there is a small rubber piece hanging down (around where the screw holes are). On the replacement piece it's just a metal piece hanging down in the same place. Do I need to have that rubber piece on the replacement charging port? Would it even affect the functionality of the phone? Is there a way to take the rubber piece off the original and transfer it to the replacement, or should I just buy one with the rubber piece on? If someone has asked this question already forgive me, but I did not see it in the thread I skimmed through.
Here is a pic of both them side by side. The top one is the original and the bottom is the replacement I got from ebay.

It would not let me post link yet so just remove parentesis and spaces to view picture link.
That gray part is for waterproofing the microphone I believe. It just slides off of the old part and onto the new one, just be careful. Also if you have no signal, by now you may have already found the following thread. I had to do this a couple of weeks ago to get a signal: http://forum.xda-developers.com/showthread.php?t=1950114&page=5 I'll try harder to match up the part numbers next time!

i'll report back once i have them
i already took the phone apart just to peek around inside, the part looks just like what's already there. the picture shows some teal/aqua colored tabs towards the bottom, im assuming these are peel off for an adhesive (there did seem to be an adhesive holding the part in place).
based on that link mentioned i would say that cutting is a little extreme, it looks like they cut the board in half, which is definitely NOT how it comes stock.
again i'll report back once i've got the chips. and for under $8 with free shipping i cant really complain even if they dont work out.
The only thing you're actually cutting (electronically) is the ground plane of the board shared by the antenna/radio and the charge port. In short, there's a super low risk of messing anything up, unless you use a sawzall to complete the job.
I assume that it was more cost effective for Samsung to put those items on the same board, but it's a punk move to attach a known replacement part to an antenna that varies by region. Either way, I'm glad to know that the hack is an option but I'd be happier to know that the hack isn't necessary.

Just wanted to report success. The part from new egg worked and was really easy to swap.
I don't have the right size sim card anymore since switching my primary carry, so I can't test reception, but otherwise everything is working (charging, wifi, Bluetooth, etc)
P.s. I did not modify the item I received (no cutting) and it is a 2.3 where the original I removed was a 2.2. I've saved the 2.2 just in case something comes up.

Thanks, but I'm afraid that we won't know whether the replacement part is a proper replacement until there is a sim-card involved. Reception is the rub (see post below from the board-mod thread).

I'll see if I can find a friend with a full size Sim over the next few days and test the reliability. But honestly I'd have to it may be better for people to find a rev 2.2
But for anyone who no longer uses the phone for cell service, the new egg part works great for a cheap and easy charge port replacement.

That`s how you boost your network signal ( Picture included )

Hello everyone i just bought htc amaze last week and i saw that there is a network problem with a lot of people and i heard about the aluminum foil trick so i said what the hell let`s give it a try it worked 200% and the funny thing is it also improve my WiFi strength so that is how i did it.
Tried, doesn't work. No improvement seen.

Putting aluminum foil on your back plate where the WiFi sensor is, is supposed to boost WiFi signal strength. I did a science project on it once, it actually worked. When you do it you need to make sure that the foil isn't crinkled or anything. It depends on everyone's phone, some get little to no improvement in signal.
I tested it again and it really improve the signal.

According to this thread, someone put the foil on the contact on the left of the camera piece and said they had significant improvements in WiFI signal.
We can infer that the WiFi chip is built into the back, and not the motherboard if WiFI doesn't work when the back is taken off. (Correct me if I'm wrong).
The foil is supposed to reflect the signal onto the contact piece, or motherboard. It doesn't really matter where the foil is as long as the trajectory leads to the actual wireless chip.
As Superafnan said, it improves Wifi signal, but you have to go the link which Superafnan mentioned.
You can't put the foil where you put in pictures. You should cover Wifi antenna
Off topic, if you cover your phone with the aluminum foil completely, you will lose operator's antenna
Good for fooling friends. You can tell them you were unreachable
antenna foil
antenna's in the back cover, thus loss of reception in removing it.
foil between the cover and phone body would either reflect signal to the antenna, or reflect it away, depending on the direction the antenna faces relative to the signal.
or cover your camera, or short the heck out of your phone or battery, depending where you put it.
How to Boost WiFi Signal with Aluminum Foil?
You could easily get better signals from your old router to your laptop using this life hack.
The steps are:
1. Find some Aluminum foil.
2. Find a small box (your router’s box will do the job).
3. Stick the foil on the surface of the box.
4. Create holes on the box to put the antenna in.
5. Put the box cover with aluminum foil onto the antenna.
