I recently replaced my note 2 chassis but found that my wifi signal has decreased (around 2 bars)
does anyone know where the wifi antenna is located as i can just salvage it from my old chassis.
I exchanged the below component but the signal doesnt seem to have changed at all
Hi!
How have you solved this issue?
I bought one replacement cover too and I'm having the same problem.
Thanks

Hi all,
i replaced the screen of my HOX when it got cracked.
i replaced it myself with a new screen from ebay.
the screen works well but after the replacment i have a really bad cell reception.
mostly i only have a gsm signal, a 3G signal is rare.
inside a house or building i have no signal at all.
i opened my HOX again to check the coax cable but this was not the problem.
can anyone tell me what hardware parts take care of the signal from my provider?
thanks.
nobody?
is it possibly that the two connectors circled in red are responsible for the provider 3g signal?
see attachment
Hi y'all,
I have been battling to fix my HOX 3G signal for months, I have taken it open, bent all the pins I could find upwards but it was still [email protected]
Where my iphone, defy had 3G or HSDPA signal, I only had Edge, where they had Edge, the HOX only had G.
I even changed the back cover but it was still the same
So one day I managed to break the antennae cable (after reopening and closing so much) and I realized the antennae connects the little L board which then connects to the antennae on the back cover. (not sure if it was posted before but where ever I search no one mentioned any 3G or GSM antennae location or diagram)
Long story short, after replacing the L board, my phone is finally seeing HSDPA signal along with every other well built devices I have/had.
Those with antenna problems can check the following:
Try flashing different radios
Check that the contact on the L board is connected with the back cover (the back cover plates which makes contacts to the L-board should be slightly dent)
Check that the antennae cable is secure on both points (L board and motherboard)
A loose connection on the antennae could cause signal drops or no signals at all.
Hope this helps the others, now I can finally enjoy the HOX as a phone...
ps I brought the L board in China @ $7.5, also replaced the antennae cable @ $2, not sure how much it will be in your area. I attached the pics of the L-board for those who dont know what I'm on about.
Cheers!
Hi, i recently got this one x (13 months old, out of warranty)
and found that the signal reception of this phone is quite weak!
I tried with SIM Cards of different mobile carriers but same issue with all of them..
it doesn't captures any signal at most of the places however in the areas with high signal strength, 3-4 signal bars appear and phone works fine!
Is there any fix to it? (Hardware issue or software?)
Also, the G-Sensor appears to be faulty, sometimes rotation works and sometimes it doesn't!
and the proximity sensor doesn't work at all!

What ROM are you using? If stock ROM, try doing a factory reset. If not, try reflashing the ROM or try another ROM.
Hardware fault it is, connectors are in very bad shape, nothing can be done
how do I do that

Hi,
I desperately need your help/advice.
I'm suffering from the same problem as you are, running my HTC One X on Stock NON-Rooted.
I've tried to factory reset several times, but still, I'm barely getting 1-2 bars of Signal Reception at Max, while in most places I get NO SIGNAL!
What did you do to fix your phone? Which jumper were you talking about?
I'll appreciate your advice...
Zach.

Hardware fault it was.
I was on stock rom, restored stock backup multiple times, did factory reset, none worked,
ultimately just one jumper, did it all! :laugh:

There are some pins on the motherboard that makes contact with the antenna inside the back cover. With time, those pins bent downward to motherboard and makes poor contact with the antenna. You need to remove the back cover and repair those pin or bent them back up.
look at this thread, its for the wifi issue, but essentially the same solution. http://forum.xda-developers.com/showthread.php?t=1688538

Thanks, I've already tried the pins solution. I even replaced the whole back cover.
I guess my only chance is to replace the inside coax antenna cable, unless the problem lies inside the motherboard somewhere...
Thanks anyway...
Does anyone else have this issue? My GPS loses connection to the satellites every couple minutes. And yes, I have the latest map update.
Must be the bug in update. Try to use 3rd party app! Just because i never updated mine, and is working like a charm

The GPS in my phone is not very accurate. Maybe its just this phone. I only get relatively good GPS reception at night.

Thanks guys. I'm starting to think it may just be this phone as well. The first map told me I was 3 miles away from my house....lol...and the second was accurate but keeps dropping the signal. I do have carhome. I'll try that and see what happens.
I also have this issue though the GPS (which is used a lot by me) was quite OK in the beginning after I bought my LG OG PRO.
I read in one of the Samsung NOTE forums that people mention the same problem claiming that the drops come when there is an "interruption" (which can be an incoming call or SMS or switching from 3G antenna to 3.5G for example). After reading this I realized that my GPS gets lost always after an incoming call plus I see at least a couple of places along my daily driving routine where GPS is lost exactly at the same place every day (making antenna switch assumption logical).
There were no any conclusions or suggested solutions in these forums, people even do not know if it is software or hardware related.
Anyone has such an issue too? Any recommendations for possible fix?
I can't believe but it seems I solved the problem with GPS - 15-20 seconds for GPS lock, no dropping and GPS test application shows very nice picture of 8-9 satellites constantly locked up while most of the signal bars are yellow (i.e. the signal strength is good).
I searched a lot as it really bothered me because I use my GPS very much plus I can say that beside this annoying thing I am very satisfied with my LG OG Pro, but nothing helped until I found this video: https://www.youtube.com/watch?v=QBpNtWvY454 (it explains the solution for Nexus 5, but my problem is identical)
Basically, the problem is that there are special contacts on the motherboard connected to the GPS antenna which is part of the back cover and the contacts are not tightened well to the GPS antenna (look at the attached picture where I put the red arrows at the relevant places). Due to the bad touch between the contacts and the antenna, the GPS does not work properly. So, all you need to do is to remove your back cover, gently "un-glue" the GPS antenna end (the rectangle part on the back cover containing 2 golden dots), lift it up a little and put a piece of paper that will tighten the antenna and mother board contacts when the back cover is returned. Good luck.
It is NFC Antenna, you cant fix GPS this way.
I have same issue, but i think NFC and GPS antennas are different. I am disassemble the phone and pull up all golden springs - but gps still very weak(((
Any solution?
same GPS problem for my g pro.
GPS is weaker and weaker
I realigned all the pins inside the phone and fixed it for a bit, but the signal was still weak. I figured it was the modem. I installed a custom rom and it worked like a charm!
Yesterday i replaced battery in amazon fire phone bought from amazon USA. after replacing and charging wifi signal disappeared. when placed fire phone on the modem it start picking up wifi signal. Can anyone tell me what i did wrong.. I am assured that i didnt touch any part of the cell phone inside.just smoothly removed battery and closed cover.Anyone give me suggestion...
Thanks in advance
You might have loosened the antenna connectors when replacing the battery. They mentioned that in the following link.
https://www.ifixit.com/Teardown/Amazon+Fire+Phone+Teardown/27458
Helpful website. but I couldn't find where is the antenna which I loosened it...need disparate help..
Same Issue Please Help!
I replaced the battery, and just after, discovered the phone would only pick up 5GHz WiFi bands when it was extremely close to their sources.
I followed that link, opened up the phone, checked those connections(which turned out to be perfectly fine) and broke something else...a pin right above the WiFi connection and just below the big camera. The one that came off was in the middle.
What do these pins do, and how do I fix them? Also, what is wrong with my WiFi antenna?!?
