I just want to write this post maybe it will help anyone that has or will have the same problem. I looked all over the internet and could not find a fix, so here is my fix. Hope it works.
I work over seas on oil rig sites (remote locations) so I talk to my wife and family back home via different VOIP apps so its important to get a 3G signal, usually I lock WCDMA only network and get at least 1 bar which is sufficient. All of a sudden I started experiencing very weak 3G signal on my phone, weirdly this was at the same location where it had full bars in the past. This only applies for 3G, I could get 2G signal no problem.
In other areas that I know had good 3G signals and towers were close, it would work alright outdoors but once I get behind a door or a window 3G disappears even if I have it locked. I put in my sim card in my old Galaxy Nexus and it had 3G indoors with no problems at the same place and right next to the N5. So I started testing with both phones right next to each other when I lock 3G with the same SIM the Galaxy nexus would get 3 bars while the Nexus 5 would get the empty triangle (emergency calls only).
I couldn't get out of my mind that I dropped my Nexus 5 a hard drop, but I have a rubber case that took all the shock and the phone didn't get a scratch on it. This was before the 3G signal starts getting funny. Couldn't help but feel that I broke it somehow though. I felt like this might have got something loose inside. What didn't make sense to me is that if the antenna didn't work it wouldn't get 3G at all, indoors and outdoors.
So Step 1, I assumed it was a software issue. I went through a painful hard reset. To my surprise it still had the same issue afterwards.
Then out of desperation I saw this dude's video on how he couldn't lock GPS until he opened the back of the phone and found that the GPS antenna was not connecting straight.
youtube com/watch?v=K1-uCIb-t8I[/url]
So I started searching for where the 3G or 2G antennas are on the N5, but couldnt find anything that points that out. The phone was worthless to me like that so... I took a deep breath and decided to open the phone. Keep in mind, i'm an oilfield engineer and I still had a feeling i might [email protected]#k the phone up, specially that I did not have any tools with me.
So I watched this video on how to open up the back cover:
youtube com/watch?v=mkbmtu-1KSQ[/url]
and went through this guide on what's inside the N5:
theregister co uk/2013/11/05/nexus_5_teardown_shows_a_light_touch_thats_easy_to_fix/[/url]
Then I opened it, couldn't find anything to do, except maybe clean the minor dust off and blow on the ICs a bit. There is alot of pins that connect to antennas located on the back cover itself, so I closed it up, made sure its closed tight and all the pins touching, put in my SIM, and GOD DAMN!! IT WORKS AGAIN... I was getting full bars 3G!!!
So what I figured is that when I dropped it, one of those pins moved a little bit away and broke the connection between the antenna and the IC. Works great for the last 5 hours, solid connection.
Hope I would help anyone with this

Thats nice , but lots of ppls have the signal issues with nexus 5 , and it isn't antena disconect for 90 % if us. I have separated the phone many times. , done about 5 hard resets's tried diffrent verions of radio's diffrent ROM's etc... nothing work's. Frineds have nexus 5 2 of them , and they can get 3g and 4g when they want, and i can only get Edge which is 2g. which is unusable..... I noticed that i have 3g only when i am in other towns, but not mine home town.... I tried diffrent sim cards, and diffrent netowrks, nothing seams to get the 3g at home, plus the gsm sucks, it interupts the calls.. So i must be the frequencies of the working 3g network in mine home town ? Then how i don't get 4g ? Why other ppl with the same phone, and same network have 3g when put next to mine ? NO one knows...
Same Issue
i am having the same issue, just having "E" Edge and cannot connect to 3G/4G, done everything to resolve the issue, took apart the antenna part of my phone but all the connectors and wires are intact, did hard reset several times, tried different ROMS including stock ROMS, tried the *#*#4636#*#* selected all the Radios but no luck, used 2 different sim cards but no use, same damn "E" in the status bar, APNs are all in place, nothing is wrong with the settings so far, dont know wots da problem with this set.
Please help us.

I was messing around with my captivate and i was noticing it wasnt getting same amount of service that my old iphone 3g did. When i was in an area where service was quite sketchy , i would put it down and get two or three bars. When I picked it up in my hands it would drop for one bar or no service.
So the question is do we have to buy cases for these phones since service drops so much by having direct contact with the phone ?
no, cases are not necessary for reception.
If you are completely losing signal when its in your hands, you need to go to att and get a new sim card. If that doesnt work, have them replace your phone.
Note: if you are holding the phone by the bottom and losing bars but your signal is not dropping, this is perfectly normal. All phones do this to an extent since the antenna is located at the bottom. If you completely lose signal or drop calls because of it, you have a serious problem.
what i have noticed thats not just 3g reception its wifi too which is weird, i pick it up in my hand i lose a bar of wifi when i am in the same room as the cablemodem/router that doesnt seem right.
Usually when i pick up the phone it drops the three bars i hold it in my left hand usually. Another issue is i bought this phone thru amazon since it was 30 bucks cheaper for upgrade price, will att still allow for trade in or do i have to send back to amazon ?
I too have noticed this with my phone. Never really noticed until this iPhone 4 shiz came out. Guessing its par for the course.
areas where i used to get full bars i am not getting full anymore when i pick up the phone, it also happens with wifi which is really problematic.
Sitting in same room as router and cable modem and dropping below full wifi connection, and if i walk out of the room drops to one bar of wifi guess i will have to call att tomorrow and return my phone
Kind of off topic how thorougly do they check thier phones am i going to have to find an rom that has all the att bloatware stuff on it ?
This is a sad day really liked this phone , but appears i am going to have to return it , since this issue is a known issue so getting a new phone wont make these problems go away.
I was reading on another forum site that a lot of people having this same issue oh well i guess
wifi doesnt drop for me... thats really strange. in any case if you are only losing about 2 bars its normal and will happen with most phones. If you lose signal completly then its abnormal and ur phone/hardware is faulty.
yeah was reading about antennae issue on back part of phone where the battery cover is you cant touch it apparently. well i am going from 2 or 3 bars to zero bars pretty much.
An good example would be when i went into apple store which has 3g microcell tower in the store to hide the antennae problem with iphone 4 , i dont get full service and the iphones get full no matter how hard you grip them.
Going to give both samsung and att a call tomorrow morning to see what i can do i really dont think its fair to have to eat the upgrade and restock fee when phone cant perform normal functions

If you got the phone from amazon and are returning it, then it is free to return with no restocking fee. At least thats what they told me. All you gotta do is call the number for returns so u can get a return shipping label from them. Did you ask if you could exchange for another captivate at a local At&t Warranty Center?
I will be calling att and samsung tomorrow when i wake up to see what they have to say. As far as returning it to att, if its a known issue then an replacement phone will have the same possible issues.
So i did an little experiment to test 3g and wifi. I walked across the room, which has the modem and router, and stood by the door. got no 3g service in my hand, and the wifi dropped from full bars to just 1 bar of wifi in the same room.
I don't know what you guys are talking about. I can touch the phone any which way and the bar fluctuates by a single bar, if even that. I get more fluctuation walking around in my house then I do holding it. The only time I've ever noticed a significant drop in reception has been literally covering the phone front and back with both hands. Maybe you guys are just in poor reception areas. Before you completely discount the phone and send it back, instead of relying on the bars, look at the actual db signal in the settings.
I have looked at those i get an big fat zero. the other issue i have is my wifi goes from full to 1 bar by just moving to other side of the room thats not good at all.
I have been to areas of my town where i know there is full 3g service, and i get maybe two or three bars. i was thinking maybe an case would mask that particular issue since i am not directly touching the phone. The fact that i really like this phone i would just do the case thing if that were a solution

I will admit the area where i live doesn't have the best reception in the world, but when i place the phone on an table or sofa, i get -105 dbm and 4 asu. once i pick it up drops to 0 dbm and 0 asu quite odd.
Just to make sure, I removed my phone from it's case, and plastered my hands all over it. With a solid 3 bars, I touched sides, with two fingers all the way to a two handed deathgrip. Not only did I not get a degradation of bars, at one point I got a bar increase! I palmed the back, front, cradled it my hands, held it to my body. I didn't get any change in bars.
Maybe it's the band of cell phone signal in your area. I know that either the 1900mhz or 850mhz is better than the other in terms of penetrating power, so if your signal is going over the weaker one, that may be the issue.
I am just going to give samsung a call , when i actually use phone i am not touching the back of the phone. I have taken it into area where usually you should get full service and i dont get it if i hold it in my hand.
I also did an comparison with my old 3g iphone and the 3g was getting two to three more bars...
The other major issue is my wifi signal dropping from full to one bar in the same room of the router that shouldnt be happening
well its like i said, this signal issue that you few are having isnt that wide spread. go get a replacement sim, if that doesnt work then simply have ur carrier replace your phone. you should be within the 30 day trial period anyway... dont bother talking directly with samsung, getting a phone replacement from att would be quicker.
well the only issue with returning the phone i dindt buy it directly from att , got it thru amazon so returning to get a new one may be a bit problematic i think.
The iPhone's issue is different - it has an external antenna, and one finger in the wrong place rendered no signal - one finger bridging the gap between antennas - creating an electrical conductive circuit.
The Captivate (and all other phones) have internal antennas covered with plastic (the phone's case) - so the antenna is already covered.
Apple tried to deflect criticism by talking about "The grip of death" killing signal on other phones. While this is true, it is not what plagues the iphone - although it can. All phones will show signal drop if you wrap your hand (or some other signal blocking material) around the phone.
The Problem with trying to measure the signal drop, is that signal bars are not very accurate - you need to be in the phone menus where it shows you actual signal strength in DB - I don't think you will get this for WiFi though. Then of course there are all kinds of external interference issues - Microwave ovens, cordless phones, etc.
So, unless you measure this stuff in a controlled environment, like consumer reports did, where you can control the transmitter and all eliminate all external influences, then most observations are not including all environmental factors.
My phone works great, regardless of what the bars say.
well i have seen my phones service go from -105 dbm 4 asu to nothing when i picked up the phone. and then i would get the nice blue circle with line thru it.
I did an speed test also with phone while holding it and when putting it on an table , the times i would actually get no bars on my phone while holding i would get 1/3 the dl speed of when it was sitting on a table.
I will have to wait till tues to get an replacement phone and hopefully i wont have the same issues
so are you getting the replacement from att or amazon?
I have not done anything software wise to my phone, its still a factory rom and radio for ATT... now my issue is I'm struggling all the time with reception with this phone. I don't remember it being this bad when I first got it and now its just becoming a huge annoyance.
I'll have phone calls breaking up with a display showing 3-4 bars of service and also having troubles sending txt messages quite often.
I'm in an area that is labeled as HPSA coverage area and my "voice" coverage map for my area is not bad at all... for example where I work is listed as "BEST" coverage and if I walk outside I'll have 2 maybe 3 bars of service.
There is nothing visibly wrong with my antenna/sim cover but should I attempt to replace it and see if that could be causing the problem?
There is nothing out there on the web for improving reception on a Inspire 4G phone and there is now way to shut off the HPSA and revert to 3G, but at the same time I really should have to since my whole state is covered with blue for HPSA coverage.
Any input on things that I can try would be great.
Thanks.

hpsa is basically 3g just optimized packet transmission. You can change your phone to run on edge network (which is why i personally do because then i can get a ton more battery life) Also it doesnt matter what your area is 'claimed' to be for coverage, there are a ton of outside factors that influence your signal. What you can do is take the bottom cover off and clean the gold contacts on the phone itself with alcohol and using something metal, lightly scrape the cover-side contacts to shine up the metal (but not removing the material itself)
Well aware of all the things you mentioned, as well as I've tried cleaning the contacts multiple times. Used an eraser on the cover side to polish the contacts and got no improvement with signal. I also can not find any way to shut off HPSA or 3G on this phone... and I've read that with the AT&T Inspire it's not possible. I'd love to switch to Edge when at work because as you said it would extend battery life immensely.
But I guess the real issue is I never had these problems before with any of my phones or this one at first, granted I have some dead spots which I'm well aware of and accept since I do live in the hilly north east corner but to have this phone degrade with signal over the time I've had it just seems a bit odd.
I was just wondering if anyone else has experienced signal loss with an Inspire 4G over the life of the phone without having any physical damage done to it. As well as having much less signal strength in comparison to other phone models.
I'm contemplating getting a new phone but I want to ensure that whatever I get would have better reception. I'm close to my 2yr resign IIRC and when I do find out that date I will probably replace this.
Its just the whole antenna on the Inspire seems to be lacking and very small in my mind, and placed very badly.
*#*#4636#*#* dial this and get into your config menu. change network type to edge/gsm i think it is? been a while since ive used stock ui
fyi the antenna is supposed to be small as it has to be designed to receive certain frequency. antenna length has to do with what signal it is using. bigger is not better
theres an app on market called 2g/3g toggle. it will put a button on your screen to take u to that menu screen instantly
That worked but which network do you switch to, It was on WCDMA Preferred
Also that app only brings me to the network settings in the phone, not to this menu.
I selected "GSM Only" for now to see what it does.

correct, gsm only will keep you on edge network. if you want your regular hspa+ setting just change it back to wcdma preferred
I'm all of a sudden having no service, i think at&t is having issues.

Moving to Q&A
This is a matter of interest to me as well. I've been looking at some videos for "fixing" the reception of other phone models by finding the gold contacts and extending the "antenna" by attaching a piece of aluminum foil to the antenna points. Now with the Inspire, the contact points are in the battery cover, but you'd have to open the unit itself to see anything more than that. I'm thinking that some reception problems may be due to worn contacts. I'd be interested in what kind of substance would be appropriate for "restoring" the contacts. Also I'd be interested if someone *has* opened up the unit and "extended" the antenna with something like aluminum foil.
From what I could gather the cell antenna is actually on the bottom cover for the SIM an SD cards. All I did was use an eraser on the contacts to clean them up and yes I did try to lay down foil to extend the antenna but from what I have read regarding radio's and such the antenna size and shape is specific to the signal its trying to pick up, so that could either work great or fail completely when you try to extend it. It did not help for my situation at all.
Lately the phone will not send txt's with one bar of HPSA or just on Edge which makes no sense to me and also I'm quite often only getting one bar unless I can see a tower right next to me which is a bit sad and I do not remember having this issue before.
Also changing the preferred network did not prevent it from using or wanting to go to HPSA while I'm at work. It would operate the same as before. Its impossible to get this phone to stick on regular 3g which I feel I have better coverage of that network in my area.
I'm contemplating rooting the phone and trying some different radio's on it to see if that will help me at all.
I never had this many signal issues with my 3Gs and I'm contemplating going back to that phone until I can upgrade again since this is just so aggravating... More so than having to have the same txt sounds as everyone else with an iPhone.
I think it us just AT&T having problems on their side. Some days I gave great reception, and others it struggles to maintain one bar all day. Its getting very annoying for me, and I probably won't be with them for much longer...Verizon looks much better right now.
Optimus T...Ok I got this phone from my uncle because his dog chewed it a little. I took it apart and the teeth went through the plastic casing and made marks in the metal frame but there was no visible damage to the internals. I replaced the frame and the plastic casing, boot the phone up and tested it for a couple months.
The phone is running:
cyanogen_thunderg-ota-eng.mik-6.5.8
franco.Kernel.v19.4-cfs
(I am not even sure if that ROM and Kernel are out dated or if there is a more stable ROM/Kernel to be used.)
Anyway, the main issue I am having with this phone is really strange. You see normally people have Network signal problems in buildings maybe even in their house but this phone is completely opposite. When I am in my house or in a building/store I have no problems and network strength is at mid to full. When I am out though driving around even in the busy part of town where you would think the strongest signal is, there is absolutely no network strength. It doesn't even register a network in range at all.
Any ideas what could cause this would be helpful, thank you. The only other issue I have noticed with this phone is when you put someone on speaker they hear echoing but I don't think the two issues are related.
Nobody has any thoughts?
Please someone. More info, Mik's says OLD BASEBAND and I have v10a. When I go to Networks it lists two tmobile and one cingular. It says it cannot connect to any of the networks.
I installed devoid-froyo-final and it actually finds two family mobile networks (like it should) and one cingular and can connect to them all. What is the issue here? devoid-froyo-final actually even lists them as cdma, gsm and Mik's does not show this info
Well though devoid-froyo-final registered the networks better, in town I still have the same issue. It can not find any networks and has no signal. This is in the same area my other phone has full bars and 4g... I wish I could figure this out I like this phone as a back up, oh well.
1) You're on the old baseband i.e v10 which was a bit weaker than the new baseband i.e v20 imho.
2) These sims work on other phones without any niggles ?

I stay in africa(uganda) I sold my nokia n900 to buy a used unlocked tmobile samsung S 4G vibrant which has become my worst nightmare...the phone drops network signal and sometimes when I pull it outta my pocket it will show (searching) but will connect after 30minutes else i have to reconnect it my self in network setup..all that was not a problem to me because I work in the capital were network is always up in 5bars both 3G&2G but loses it quickly in some building..
Problem:
When I leave the capital just 15 minutes away it starts to drop signal from 5-0 but will regain in some places...it does this in areas that other people on the same network as me won't get a problem so do my previous 3G phones including the previous n900 I owned.
Things get bad when I reach home in that I barely get a bar in 3G and only 5-4-3bars in 2G it keeps on playing and in that process it will go to (searching) until I reconnect manually which forced me to look for a solution on the internet.
Solution I got:
Connect magnet wire in the back external antenna input at the back of the phone, guess you all have seen that hole, in the video the guy got 3bars from 0-1 bar which convieced me that my network problem is now solved.
Starting the trick:
I cut my tv antenna wire in two pieces, removed three thin silver wires and tested one by one.
The first two failed but the third one brought the network down from 0bars of 3G upto 3bars 3G.
Going on with the test now very happy I try a more fitting object I inserted the niddle which I used to remove the rubber cover which covered the external antenna input.
My nightmare begins:
Immediately after I removed the niddle, the signal bars all went off to X but mine shows a circle and a line touching both sides.
When I reinserted the niddle I got the signal back but this time only 2bars for 2G which was 4-5 bars before and 0bars for 3G which could dare 1bar.
finally:
Now I just removed the niddle, network went off again now my phone was relying on the niddle maybe the internal antenna was now disabled or ruined by me.
I hard reseted the phone, cleared cache but all didn't work..i put back the niddle in the hole It all came back.
Yesterday I took it to a local repair shop and today when I picked it I had -79dbm 2G and -53dbm 3G but when I left the shop 15 minutes away I got an X then 5-2-3 bars of both 3G and 2G..thaugh i got the network back without niddle support. The network is badder than how it was when I first bought the phone.
What the repair guy did:
He rolled a copper wire around the external antenna input and soldered it to an object just near th ext antenna input.
Finally:
What could have been the problem in the first place?
How can I solve the problem?
Phone: tmobile samsung galaxy s t959v vibrant.
State: unlocked and being used on airtel uganda.
Android Version:2.2.1
my last say: I have tested 3 different 3G phones with my simcard and all have performed well in my house with full bars and I don't remember having network issues with my previous 3G nokia phones, my brother who has a galaxy pocket doesn't face network problems either..i have tried all network operators with no success but still the same problem and now come for your help because after the niddle night, alk has become was! I like the phone soo,much cause its my first android but am afraid I can't have it like this, friends call me and it has already disconnected from the network even when the bars are still there in full swing..........
Hello guys and girls,
after experiencing some GPS problems (loss of signal on the road and/or late fix) I did the fix found on youtube (Where you place a bit of paper/tape under the GPS antenna contacts). It worked just fine, my GPS fix is now happening faster and I did not lose the signal ever since. But I am now facing some (weird?) problem: My GSM connection (GRPS, EDGE) is really really bad. In my room I don't get any signal at all, outside I get like 1 out of 4 bars of signal strength, but I lose it after a few seconds. I normally have 4 out of 4 bars in my room. BUT: My 3G connection works fine, 3G, LTE, same connectivity as before.
My friends phone (same carrier) does get the full GRPS/EDGE connection in my room, so it's not the carrier having problems. I didn't do any updates or anything in the last weeks. It would be a huge coincidence, if a software bug happened while I fixed the GPS problem, so I assume it's a hardware related thing?
How might I fix that, what possible solutions are there?
Tried the following so far:
Restarting multiple times, with our without airplane mode
Re-inserting the sim-car
Switching between LTE only, GSM/LTE, GSM only
Flashing new/other modem
Replacing the speaker/antenna-module
-> nothing changed
out of sheer curiousity, and after reading your post, im stuck wondering.. why do you want or need your gprs and edge connection when your 3G/LTE is fine? data speeds are very slow, and drain lots of battery using anything internet or download related..
Yeah, sure, 3G/LTE is better and coverage is really good where I live, that's why it's not an emergency for me, but it's very important to get it back to work properly.
I know at least 2 situations where I really need GSM (GPRS,EDGE):
1) At work (huge metal building, no 3G/LTE, only GSM) -> I can't call, text or do anything with my phone (don't worry, I am allowed to do so and no, there is no WiFi)
2) On the road, especially the german autobahn has large areas where there is no 3G/LTE coverage, so I can't use my navigation-software properly and can't respond to calls or whatsoever
So all in all: GSM in really important for me. Please help me. :crying:
ahh.. I see.
and your GPRS/edge was fine before the GPS "fix"? maybe something got loosened?
Before I did the fix it worked perfectly fine. Directly after I did it, the gsm was gone so I figured that I somehow damaged the antenna. But since I replaced it and nothing changed I am not sure what to do now. Are there other antennas, are there other modules that influence gsm, that I might have damaged or loosened?
That's what can happen when you tinker with guts of your phone. You risk damaging or messing it up. Sorry, I don't mean to sound like a jerk.

Yes, dave2metz, I know. I was fully aware of that when I opened my phone for the first time to fix the GPS thing. But I am not here for moral advice.
Any ideas how I could fix my problem are highly appreciated!
Edit:
Just checked: The sim-card is not the cause of the problem either. I would really appreciate some good ideas guys..
No idea what I might try?
My best guess is that this is a hardware related problem. But how does one fix it? I replaced the antenna (the bottom thing), nothing changed. So that specific antenna was not the cause of the problem.
Are there other antennas?
Are there antenna-connections that I could check?
Any other hardware things that I might check?
Anything that might have lost the physcical contact inside the phone because of that GPS fix?
Could it, against all odds, be a software problem?
Please, I am really in need of a working phone. If I can't fix it I need to replace it sooner or later because GSM is essential.
If anyone can provide me with an idea or something that leads me to a fix, I will reward you (amazon gift-card or whatsoever).

Did you figure it out?

Did you end up figuring anything out for this? I have something along the same lines. I dropped my phone and smashed the screen. I was able to get a guy to replace the screen portion of the unit, but immediately after I got it back it had no cell reception. Rebooted came, back thought everything was cool.
After a couple weeks I notice my phone has lost reception occasionally. It's now gotten worse, I used to be able to reboot it about 5 or 6 times and then it would randomly come back. I've even had it come back without performing a reboot on its own.
I ended up taking the whole thing apart, reseating everything after having a day and half span where I have been unable to get it back and boom reception came back. Thought it was his repair job at that point, but it has since dropped the signal again and I can't get it back. Yesterday even I was showing LTE signal changing from low to strong etc, but my network was still down as I couldn't perform a search, maps, or anything.
I have my phone apart again. I've checked all the connections over and over and wondering what else to look for or try to replace. True my impact could have damaged a component on the mainboard, but my phone works fine in all other areas. I could replace the antenna wires and the antenna/speaker module, but I'm not sure it just a reception problem.
My phone also boots into airplane mode when it has no signal, but turning it off does not restore the connection or anything. Rebooting it puts it back into airplane mode. *#*#4636#*# shows my radio is off. Thinking it's a short or something somewhere, but I doubt I'll be able to fix it in that case - at least without a mainboard?
That's my other question, what part need to be replaced for experiencing no network and its not the antenna or antenna wires? Is the mainboard? Sister board? Currently researching teardown as this phone is modular and I'm sure I could source the part off ebay or something.
Hi,
There's one antenna for 2G/3G/4G so I think if this problem was caused by hardware, it would affect overall connection to mobile network.
I think that this might me software-related problem but actually can't figure out which. Only thing I'm currently thinking of it that your phone has problems with connecting to certain GSM band. For example in Europe are 900 MHz and 1800 MHz standard for GSM.
Lower frequencies bring you better coverage. Your phone might have trouble with connecting to them and automatically selects 1800 MHz layer.
If you are able to get another phone with SIM of the same network provider, I recommend you to download any networking app and compare data about cells. Mainly CID number. It's unique identifier of each cell in an area.
If both phones are connected to same cell (CIDs are equal), you have to compare RSSI values. Lower means better signal. RSSI is defined as a negative number in an interval of <-51; -113>. So -75 dBm is better than -89 dBm. In one place should be difference about +/- 5 dBm.
Reaching slightly different RSSI numbers while connected to same cell in same place might mean that your phone really have problems with radio.
hey mate,
My wife phon is having the same issue 4G works, 3G sort of works, 2G nothing.
[Did the GPS fix on my wife's Nexus 5 (and mine) also]
swapped sim, used another telco same issue.
when into service menu did *#*#4635#*#* , click the 3 dots, select radio band - only see USA band.
While my phone had automatic, usa bad , usa band, japan band.
she is running stock rom with unlocked boot loader, I am on CM11 but doubt that should make any difference.
if I work out what is going on will report back.

hello guys?.. my htc nexus 5 got wet and i notice the signal strength got lost. when i open it up i notice the lines on the antenna got damage. how do i repair it? or should i replace it with new one? Pls help !!
Is issue still remaining?
Hi. I am having the same problem. Could anyone find a fix for this?
My GPS was and is fine. I didn't do the gps fix, but I have replaced my battery and I think it happened after the replace...
