[Q] My GPS problem (probably hardware fault)

Hello, I have a GPS issue and I would like to ask some questions related to hardware connectivity etc, i will explain what happens first:
Since i got my phone, with the stock ROM i could never find any satellites. Right now i have Viper 3.7.7 with Alex-V kernel, and it's international version S-OFF.
I opened my phone and used a tester with in the back cover of my phone to see if the GPS antenna had connectivity. And it has.
I lifted the GPS connectors up a bit to see if it was a connectivity problem, however it did not work.
I used a tester and i realized there is no connectivity between the two GPS connectors, I do have connectivity between the 2 wi-fi connectors so i do not know if there should be connectivity between the gps ones as well.
I also used the tester with one of them, and it had connectivity with the rest of the phone metal stuff, but the other one hadn't.
I used a wire to connect both connectors and tested of I could find satellites, but again 0/0
I did not sold anything because I do not know if it is a soldering problem or not. Could anybody tell me if there should be connectivity between the two GPS connectors or what could I do to fix it? It is a hardware problem for sure. I have read a lot and watched a lot of videos but i think my problem is a little bit more specifil and i would need more information about how the connectors work.
Thanks in advance.

WiFi connects only in close range (need to know Antenna location)

Hey all I posted about my wifi problem before, I have V30N D855 32 gb rooted G3, I have 2 routers at home, which my phone connects to them only when am lik 1-2 meters away from the router, otherwise I get "Saved" under the network name, not talking about wifi in public where I just end up with "Saved" all the time,
I am wondering if someone knows where is the Antenna Cable is located inside the phone itself? maybe it's an antenna cable issue that I just need to screw to get better wifi
thanks
Not sure where it is, but see if you can find one of the many teardown videos on YouTube, they show every part in the phone. I had the same problem with my iPod Touch 4g, it stays connected once it gets on but you have to be close to connect it. It does sound like a hardware issue, but the part should be pretty cheap on eBay.

[Q] Issues with WiFi/Bluetooth on replacement housing

I've been through a lot of hassle with wanting the black back from a 3T for my 3.
I received the black back and it didn't have the buttons, camera lens, vibration switch or NFC antenna. Everything was working fine at this point with it fitted
I was unable to find a black back with all the above so I ordered a 3T gun metal back.
I received and fitted it but now WiFi and Bluetooth show poor reception to the point where I have to put the phone right next to my Pebble or WAP to get a connection.
Nothing has changed in the meantime, I now no longer have the original or black back.
Does anyone know what might have caused this?
I checked all the pins that connect to the housing antenna bands and they're all fine but still weak signal.
I've just about had enough of this, dealing with Chinese sellers and waiting hasn't been great and I just want my phone back to be the way it was. I shouldn't have bothered :laugh:
Yeah I was looking to fix it myself, I've seen the daughter boards which i believe connect to the housing for the WiFi and Bluetooth antennas on eBay for like £10

Unfortunately not, I replaced the daughter board located at the bottom of the phone. The rear housing and the antenna cable. None of which resolved the issue.

WiFi and Bluetooth Problem

Hi all, So my phone (wife's phone ) got water damage, after battery replacement things start working except the wifi and bluetooth I think it might be the board or the cables got damaged but could not find any information where the antenna for wifi and bluetooth are and which board actually has the chip. I will try to replace the board but don't even know which one to order. Does anybody know?
PS none of the disassembly guides or videos I saw mentions the location of these.
No one has any idea where the wifi blutooth on this device?

NFC tap & pay not working

hello there, i have a problem with my note 10 + (SM-N975F), i can use NFC to pair bluetooth devices but it can't be used on tap & pay. I already tried replacing the wireless charging coil with nfc antenna several times, thinking that it would solve the problem but with no luck. is there still a chance to repair this kind of situation?
