Hi guys
My daughter dropped my Oneplus One in the water, hopefully, there was not many water, and the only water visible seems to be inside the jack connector a red liquid was visible after)....but while disassembling my phone, i.made a mistake withmy tools and accidentaly broke a pin on the motherboard...seems related to some kind of copper antenna on the back cover...but i can't find any information. Can you tell me what kind of antenna/pin is it exactly ?
I attached a picture who show the pin i broke accidentaly
Many thanks
So far, no signal drop with wifi..and 4G network
NFC pin connector....
Thanks....but i did some research , seems to be the wifi/bluetooth pogo and not NFC. But no problem with NFC, nor with wifi or bluetooth
Many thanks
There only 3 type of receiver on the back cover of the phone (look at inside of the back cover)....
1. NFC receiver
2. GPS receiver
3. Signal receiver
The NFC receiver is in the middle of the phone, the GPS receiver is on top right while the signal is on the bottom right...

I am hoping to salvage my wonderful nexus 5. When replacing the screen I partial pulled the 3g antenna connector off of the main board. Now I randomly have service. Sometimes pushing on the back of the phone works to reestablish service, normally it does not. I was curious If I could get a custom antenna wire that would go from what i believe is the antenna test point to the normal connector on the bottom. If you think this would work any suggestions on where I could get that type of connector made
Need some fast help. I have to have this fixed in the next few hours.
I replaced the glass on a verizon s3 but i took the whole phone apart to ensure no uv glue seeped into the device. When i popped off the antenna the connector on the main board came with it. It does not look like there is any copper left to solder it back on. Anyone know a way to fix this? Can i solder the wire to big antenna connector beside it? Any help would be very very appreciated.
Never mind. I fixed it by running a wire from the antenna lead to the r1 antenna port.
Hello good people of xda. While I was disconnecting the gsm antenna wire I damaged the ever so freaking delicate connector so I obtained a new one and fitted it but.. Still no data signal. I noticed on the motherboard that there are two connection points that connect with the rear cover.
One appears to be damaged. Do these contacts have anything to do with gsm antenna.
I wonder if there are any other points on the motherboard that I can connect the wire to?
Hello! So I have an Nexus 5 D820 and after changing my battery in some areas of my city or my country I don't have any reception. While writing this I popped the battery cover and applied a little pressure with electrical tape to the black wire which I believe is for the reception but I can't tell if I fixed it because most of the time I have reception. So what should I change to fix my reception - only the little black wire or the hole bottom PCB with the plastic cover ? Thanks in advance!
Since it's working at some places it's probably not your device's fault that it can't connect at some other places. Nevertheless:
To change your battery you must have removed the motherboard cover to remove the battery cable. The GSM antenna is on the motherboard cover and is connected by simply touching 2 small conductive pieces on the motherboard (with the phone facing down and the motherboard cover removed, these should be at the top right area of the motherboard). There are also 2 wires (along with a big wire strip) that connect the 2 bottom edges of the motherboard to an extra little board below the battery (where the USB port and other components are). Those are antenna extensions, one of these is probably the black wire you are talking about. The right one is for 3G and the left one is for 4G (with the phone facing down), don't remember the colors. If you have a problem with data connection and not normal cell reception, check those 2 wires. The 3G and 4G antennas are on the black plastic cover of that extra little board and connect to it with a similar way the GSM antenna connects to the motherboard (each one has 2 gold flexible metal pins). You didn't need to remove that plastic cover to replace the battery, but if you did, remove it again and check the connector and those gold pins.
Whatever you do: NEVER DO ::ANYTHING:: WITHOUT DISCONNECTING THE BATTERY (xp talking).
Shutdown the device normally, remove back cover, remove motherboard cover, disconnect the battery cable, and THEN do whatever you have to do.
The screwdriver is usually metal and can short things. You really don't want to short something on the motherboard with the battery connected.
Thanks! I started losing signal after I replaced my battery(before that no problems whatsoever), but couple of days ago I opened the phone again and applied a little pressure to the both wires and I hope it's fixed. Also today I'm going to the place where I'm losing signal and I will find out.
As per the title I am getting a much diminished signal after changing the charging port to a new one.
The worst is when I grip it in my hand which would naturally be at the bottom - where the charging port is.
I only get LTE when I'm outdoors and indoors it's either H+ but usually H, E, or even NO SIGNAL.
I can't figure out what could be the problem. There are 2 antenna inside the unit that connect to the charging port but these are bluetooth and wifi. It doesn't appear to be an antenna for the network signal. Or is the frame part of the network antenna? I see some electronics in the frame when I dismantled and I don't know what that is for or how it connects to the mobo. I'm thinking if the frame works as an antenna maybe it's not connecting to the mobo properly.
Just to clarify I was having no signal problems before I dismantled the unit and in fact it was working exactly the same as my previous phone.
I actually don't know if the charging port part has anything to do with the signal antenna.
Any comments appreciated.
Hello,
I'm experiencing the same problems with my SM-G920F. After replacing the charging port the bottom mic isn't working anymore. I'm forced to call on speakerphone to get the sound to the other end of the line. The repair centre who fixed the phone said it could be because of a little off-point alignment when soldering the usb pin on the pcb. They also said that they experienced the same problems on different repairs for the S6.
Any thoughts?

Please start you own thread on your issue. It has nothing to do with this thread. Mod please remove this post.
I think I know what happened. When I took off the back cover plate it was glued to what looked like a Printed Circuit Board antenna and it was yanked by myself. Anyone know where I can get these type of things to buy and repair ?
