Hi
I got my nexus 5 last year around December. I live in UK but got the phone from USA. I have loved it to bits until last week when all of a sudden my network reception indoor has gone almost zero actually mostly I am on emergency calls.
I face this issue at work and also at home, I had tried the following steps to troubleshoot the issue but no luck at all.
1) My colleague at work has the same phone as me and is on the same network as me (EE uk) So I tried my sim in his phone and his in mine. With my sim in his phone he got decent reception almost 4 bars whereas his sim card in my phone produces the same disappointing results, Zero network reception and emergency call. This obviously proved that something is wrong with the phone.
2) I unlocked and rooted the device and tried all the modem versions out there for nexus 5 and no luck with the reception.
3) I installed a custom ROM hoping this might solve the issue but again I was left disappointed.
4) I flashed stock and unrooted the device and downgraded the 4.4.2 to 4.4.0 hoping maybe if the new sw version caused this issue it should revert back, but again nothing.
5) I have now oem locked the device back to original state with 4.4.2 on it
6) I rang google UK and the guys was very helpful but useless at the same time as he asked me to take the sim card out give it a wipe all the basic troubleshooting I tried already. He then mentioned as I got the phone from US he can't help me with a replacement and the phone will have to be dealt with US google. He asked me to call LG UK as they should cover worldwide warranty.
So I rang LG UK and got more or less the same answer from them as they also only cover UK bought devices.
I have run out of ideas and I can't seem to find a fault in the software of the phone, I get decent signal strength outside my house and only struggle indoors. I would greatly appreciate some help with this.
Thanks in advance

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).
Cheers,

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.
nexus 5 3g 4g damaged
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...
I have a problem with my device.
It have very bad signal reception (2G, 4G). Compared to my friends G930F, in areas, where he have 2 bars, I have not signal at all.
Tried everything:
- Factory reset
- Changing SIMs
- Flashing different baseband
Nothinig helped. So I think, it is HW related.
Because phone is not from official distribution in Czech, Samsung refuse to repair it, because service center haven't access to spare parts (they suggest it may be faulty mainboard).
I doubt send it back to supplier will solve this, because phone works in areas with strong coverage very well, no problems.
But in my case it means, I can use phone only in home and work. I experienced very often disconnection when in areas with 2 bars, that means phone is practically unusable.
I think about buying spare parts, which can inflict this and change them.
But I really don't know, what can inflict this behavior. Antenna? Mainboard?

Can you tell me what was the end of the story? I have the similar unit with the similar problem. Thanks.
Heh, nothing good.
After a bit research, I think phone has bad 2G reception. Signal was ussually lost in distant areas, deep in buildings, elevators and so.
Tried:
- New antena module HA22 - no succes
- New mainboard - no succes
- New flexi cable - no succes
So at the end, I have 2 good mainborads, one display and finally bad phone.
Now it works as a stable line in company or as a redundant phone.
Only solution is return it to seller and apply a warranty refund or change.
Maybe someone has an idea.
I recently purchased a S9 Plus from Walmart. Brand new. Its and American model SM-G965U.
Build: PPR1.180610.011.G965USQU6CSI2
Snapdragon Processor: (wish I had known earlier what a pain to root)
Android Patch Sept 1 2019.
Hardware Rev1.1
Kernel Ver: 4.9.112-16732439
#2 Fri Sep 6 13:23 KST 2019
Now here's the issue
I lose signal when I KNOW that it should not happen.
Example. Live north of Toronto, big major city, lots of cell towers but my phone shows only 1 sometimes 2 bars. GF has an apple same carrier it shows 4 bars. Switch SIMS with her and I still only get 2 bars.
Take my SIM and put it into an old S7 and BAM. 4 Bars.
My little S7 would have a strong signal that even at the cottage I could stream music. The S9 says no way.
Got a new SIM card thought maybe it's damaged. Nope No Change.
Switched carriers, installed another new SIM, still the same.
Have wiped and re-installed countless times all to the same effect no change.
Signal strength readings are always low generally between -103 - -117 32 asu
Not sure if it matters Network Connections are 2g/3g/LTE however at the top right of the home screen it shows signal strength and it switches to 4G . Do I need a 4 G phone plan???
I think its a hardware issue which brings me full circle. Is it possible to do a firmware upgrade? Or do i throw this thing in the garbage?
Appreciate everyone's help.
Peace out
M
Sometimes a firmware upgrade can help, have you tried it yet? Firmware updates also include security patches and they are important to have.
But, it could also be a loose connection with the antenna. If it is a hardware issue it is hard to do anything about it without replacing device. Can you try with another one?
Hey
Thanks for the reply. I took my old S7 threw the SIM card and its smoking.
In hindsight I think You are correct. Loose antenna would be exactly what I am experiencing. (kinda silly I didn't think of that)
I'm going to return the device and ask the reseller for a replacement .
Its just as well , I have way to may other projects on the go...like building an offset reverse flow smoker..bbq season will soon be here.
Lets close this thread and say good bye
Thanks again

Hello,
i had small software update August 29,
Galaxy S22 Ultra (SM-S908B),
since then i keep loosing mobile data and wifi signal.
I got new Sim card and I did factory reset, but issues are still here. Turning off/on airplane mode or restarting the phone doesn't help. I have normal data like 5 min and then it just freeze all signal reception . I live in the city with great signal coverage. What should I do?
But what's the coverage like where you live? Does it get better as you move around? If the coverage is good then contact Samsung support so they can maybe check the phone further

Coverage is great here. I took out my sim card today and was only connected to wifi, connection is better.
With inserted sim both wifi and mobile data reception is awful.
I was thinking to switch to eSim..
I recommend that you contact Samsung support as your phone is under warranty for 1 year. They are very good at diagnosing problems.
Hi, you mean 5G coverage? I've read that 5G antenna failure is known to happen in this phone, so you should bring the phone to Samsung so they can replace it, specially if you are under warranty. I don't see why you see a relation between the SIM and the coverage, probably it has more to do with the status of the antenna.
The problem is with both data connection, mobile and wifi.. I tried everything coz I want to avoid sending my new phone to service..

Samsung has an 800 support number you can contact 1st and they will try and diagnose your issue before sending it in. I've found they are pretty good at diagnosing issues over the phone.

Well I notice that if I take out Sim card from my phone that wifi has weak but stable connection.. With inserted sim card both wifi and mobile data connection are super weak and unstable. So basically I have this expensive with no possibility to use for normal calls
It's quite the same problem for me actually on my S908B which is on the latest September update (AVI3)
I live in a quite big city in France and my signal is quite bad, like 1 or 2 signal bars on 4G+ (i desactivate 5G as it drain too much the battery in my opinion).
Sometimes i feel like Wifi signal struggle as well at home... i don't know where this is coming from, but it's annoying me. I didn"t pay attention on when it's started to get bad signal, but it's been a while now i think
