What are the two gold contacts next to the sim card? - AT&T Samsung Galaxy Note I717

Ok guys I have an SGH-I717 which recently loses signal rapidly. I noticed that one of the copper connections were bent inward and not making good contact with the rear cover I pulled it upward and it worked correctly. Ah the problem re appeared and looked at the contact which is cracked now. I thought this was only a nfc contact any clue of what this really is. I am also lookin for a service manual. Thanks for your help in advance.

You thought right, those two contacts are for NFC. Just to see if it would affect the signal I pulled the cover on my phone and the signal didn't change at all.

Thank you its very annoying the usb port was recently replaced and signal had been acting up but it worked perfect all day yesterday its as if its the network

i777 reception

Hello all
I recently purchased a used at&t i777 and i am getting horrible reception and lots of dropped calls. I love the phone but it is basically useless as I am only getting 2 bars in known areas of great coverage. I have flashed back to stock at&t ics rom and opened the phone up and replaced the loud speaker/antenna without any improvement. Ihave also tried flashing all the modem roms I could find without any improvement. Right now I am open to any other suggestions.

Problem solved if anyone else has the issue.
I changed the Dock Connector Charging Port Flex Cable Ribbon and every thing is back to normal.
Thanks for the feedback :thumbup:

jrod,
I had problem with the 1st cheap one I bought from china off ebay. I bought one from a USA seller for a dollar or two more and it works flawlessly.
Its weird how the charging port effects it. On my i777 it got a little wet inside the port. Could tell this by corrosion when taken apart. Waiting for flex cable to come in so I can charge it up.

weak wifi

I've been struggling with weak wifi since I bought my evo near launch. Often the signal would suggest maximum strength, but still fail to provide throughput. I even tried switching to only one band instead of auto (2.5ghz), but this did not work.
I stumbled across this page http://community.sprint.com/baw/message/458225 and decided to give it a try. The basic premise of the post is that the contacts under the back cover don't make a solid connection, interfering with wifi.
I gave it a shot since it was easy. I gently pried the contact up just a bit and replaced the cover.
After one week of trials, my wifi has been solid. For me, this is what the problem seems to have been. It also worked for a close friend who was having the same issue.
If you do the fix, don't pry hard or you'll bend the tab to far. I used a needle and moved it just barely. This is not a placebo effect. According to wifi analyzer my signal has improved a great deal. Regardless, it fixed my problems. Just FYI....
And if this has been posted, sorry. I did search first but did not see a similar post.
Pine
Thanks for sharing I'll definitely give it a try

It has to be professionally soldered back to the motherboard. I had to get that done not too long ago. One broke off and it wouldn't pick up 3G nor 4G.

Only thing i could think of is you didn't solder it good enough and it's not making a connection to the motherboard or your back cover is not making a good contact. When i had one of mine reattached professionally it instantly started picking up lte and ehrpd again like a champ.

Screen off during call problem

Screen turns off when placing phone to ear as expected however does not come back on when pulled away. Only after the 2nd party disconnects will the screen come back on after pressing power button and the only to the lock screen. This is a new issue. Anyone else having this problem or know of a solution?

Are you stock? Rooted? I ran into this issue a few times with persus kernel.
I'm having the same issue. Anyone find a fix for this?
Just got off the phone with Verizon. They're sending a replacement. Something wrong with proximity sensor. Actually appears to be a speck behind glass over sensor.

I have also been having a bit of trouble with the same thing. On top of the screen not always coming on when I move the phone away from my ear during a phone call, sometimes when I pull up the keypad while on the phone and attempt to press a key, the screen will turn off. I think it's because the shadow of my hand makes it think it's back up to my ear. I see two little sensors next to the camera; one of them appears to have a little speck or dot on it. Maybe a piece of dirt in it? Can somebody who doesn't have this problem check and see if they see a very very tiny dot on the sensor closest to the in call speaker?
I've been having the same issue with my Note 2, I was wondering if this could be a software issue since I have messed with a few roms but decided to go back to stock. I've been looking everywhere for a solution, even went as far trying to find replacement files to see if that would fix it, but to no avail. I guess I'll have to replace the device.

Have you received your replacement?
If you have, did they send you a certified like-new or a brand new replacement?
Thank you

I have found a fix for this, at least for me, as I mentioned in an earlier post I had flashed a few ROMs, decided to search the other carriers galaxy note 2 forums and found this:
http://forum.xda-developers.com/showthread.php?t=2070360&highlight=proximity+sensor
Luckily there is a Perseus kernel for verizon too here: http://forum.xda-developers.com/showthread.php?t=2048013
Will do this later and report.
Edit: the perseus kernel by itself didn't do the trick but beanstown's stock root/deodex and jelly 'beans' roms did! I now have everything working like new with cleanrom installed

Stopped getting service in places I should

I was on CyanogenMod 10.1 and about a month ago I stopped getting service almost everywhere I drop calls all the time and I have no service at my girlfriends I thought it might be cyanogen mod but no one else was having my problem in the thread so I've been living with it until yesterday I got sick of it and finally found the time to ruu back to stock and when I went back to stock I still had no service at my girlfriends when I use to get service on stock and cm10.1 but it did say I had 1 bar and 3g but I still couldn't make calls or even send texts or browse the internet so now I'm back on cm10.1 and I'm wondering if anyone knows what's going on did I drop it a few too many times is there a part I can order that maybe broke in it that I could open and replace any suggestions would be great thanks in advance HTC rezound latest hboot 2.28 and radios I forget what the radios are even tried going back a version of radios and hboot cuz I'm soff but I'm on the latest atm

Have you checked the sim card to ensure there is no dirty contacts on it or that it is inserted completely?
Also, have you tried a different Rezound battery cover? The battery cover acts as your phone's primary antenna. If something is wrong or broken about it, it may not be making the proper contacts with your phone.

You could do like I did and shave all the contacts on the cover that touch pins on your phone. Make the metal shine a bit. See if that improved anything. Also, make sure your preferred network mode had lte and cdma in it

I had once problem with contacts for antenna located on the battery cover. Also, it would not hurt to check all the pins on the phone that they are spring loaded, not bent, not missing. Good luck.

Just to make sure, you have been keeping up with Fly's CM updates? For a while, there was an issue with low signal strength. It was fixed about 3 weeks ago if I recall. Maybe a little more.

All the little contact tabs appear to be there I gently pried up on them with a small screw driver and I just made a call and it seemed to work definitely better reception but it keeps cycling between 1 bar and no bars but not no service so I'm somewhat pleased i dont think its gonna get any better but i still will take suggestions and yes I keep up with all of fly's updates thank you everyone who helped I appreciate it

Metal pins behind the back cover

Im just wondering what the metal pins behind the back cover are. There are 4 sets of 2, and there yellowish/golden. What are they? And where they touch on the back cover the yellow paint/whatever seems to be worn off. Ill attach a picture of it(wont focus correctly without the lense thing)

those are you bluetooth, wifi, etc contacts to the antennas integrated into the back cover. If your bluetooth or wifi start dropping this might a culprit. My bluetooth is usually not functional (I'm waiting on a replacement that is backordered) but when it first started to go out, squeezing the phone together just next to the volume controls would bring it back. here's some articles about it:

The longer antenna is for LTE I believe. If you take the cover the top right side of the phone with your hand, it loses some dBm, and goes back.
