Hey,
so today I noticed my N4 couldn't get any telephone signal whatsoever. At first I thought the provider was just having issues but when I came home and tested my other phone it worked fine, so it's an issue with my N4.
Did a factory reset, problem remained. Then I tried activating 2G only and all of sudden the signal was back, telephone and data on 2G and everything works fine.
As soon as I uncheck 2G only however, both signals are gone and here's the kicker: even when wifi is activated and connected I get no signal. (with 2G+wifi I do however)
Had faux' kernel installed on stock deodexed, wen't back to stock kernel for now, didn't change anything else lately, problem just randomly appeared.
EDIT: nevermind, I just realized I checked 2G only on the other phone as well and forgot about it. Same problem there. Has to be a provider issue.
I've not had a 3G/HSPA signal on my N4 for a while now. Trouble is I don't know exactly when it happened as I'm generally on either WiFi at home or at work, where I know I can only get Edge.
I've tried the usual check the APN, *#*#4636#*#* and nothing's jumping out at me (if I tell it to use WCDMA only I get no signal at all).
I'm wondering if it was the 4.2.2 udpate and wonder if I've got the wrong radio - so the question is does anyone know what radio I should have on my N4? I'm in the UK on Vodafone, but I got the phone from the Play Store.
I've tried searching but the N4 seems to have had so many signal issues it's difficult to sift out the relevant stuff
I'm not rooted but I'm happy to do it if needed. Already tried a factory reset so nothing to lose!
Cheers,
Dave
have you tried a different sim card? thete isnt a specific radio per region, so thats not a problem.

Yeah, sorry, forgot to say. I tried the wife's SIM (different operator) and same issue, only got a 2G signal.
I was thinking it might have been an issue when they updated it to remove the LTE "feature"
Even i have the same problem . I am from India and also have tried a couple of sim card . Im not able to get 3g signal at all . Anyone pls help....
i have the same issue solved whit RMA my first nexus 4 was defective, my new nexus 4 changed in warranty now works well
3G/HSPA networks
participles ipntsly
I started having the same issue today in Atlanta. Had another T-Mobile HSPA phone sitting next to mine with 4 bars while I was on Edge. My N4 is < 1 week old and seemed to be OK but now I can't get it on anything other than Edge.
I've checked my APN settings, reset the radio, turned data on/off and reset the phone with no luck.
Any advice?
Update: Just got mine working, here is what I did.
Wasted 20 mins talking to Google and T-Mobile. (I don't recommend this step.)
Type in *#*#4636#*#*
Scroll down and change 'WCDMA Preferred' to 'WCDMA Only'. At this point my bars switched from Edge to HSPA.
Now, undo the change and put it back on WCDMA Preferred. Make sure it still has a 3G or an H next to your bars.
Exit and enjoy the fast phone.

This worked for me.. thanks
I am having the exact same problem as Dave. My n4 has just stopped connecting to WCDMA (H).
I have tried re entering my APN's, Turning on/off mobile network, Airplane mode, rebooting and removing the SIM. From the test menu I have tried WCDMA only but I lose my signal completely and go to emergency calls only. If I use either GSM only or WCDMA preferred I can get a 2G connection but nothing more and when on WCDMA preferred it can lose connection completely as well.
I am also with Vodafone UK.
solution for this

Go to settings >apps>all >Google framework services in this disable it and clear data and again enable it....
Enjoy 3g once again ....it worked for me

Thank you! A few seconds after doing this my N4 connected to 3G!
I have tried what solutions were posted here but everytime I switch from 2G to 3G in the menu I lose signal on my phone..

I tried this as soon as I put WCDMA preferred I lose signal, I have tried doing this in several locations as I live in the country, tried at my school where my friends get H+ and I still lose connection. tried going back to stock still the same issue
Can someone fixed this problem? "WCDMA only" mode make my N4 lost signal.
Sent from my Nexus 4 using XDA Premium 4 mobile app
Getting bars on 'GSM only'
I have got the same issue on my Nexus 4, and I still don't understand how it happened in the first place. I updated a bunch of apps before going to bed and remember waking up to no signals on my phone.
Currently I only receive signal when I go *#*#4636#*#* and set it to 'GSM only'. Any other configuration (WCDMA preferred, WCDMA only, etc) results in loss of signal.
I have tried the following with no luck:
1) Restored Factory Settings
2) Installed an older version of android
3) Flashed multiple radios
4) Steps listed on this thread
Can anyone help me out with this?
Thanks
Hello! Been using my phone for quite some time with LTE activated and working fine. Flashing custom roms and trying out fresh modems i suddenly noticed that I can only get E, H and H+ data connectivity. My LTE connection is gone. I've already checked with my provider and they said that my account is still activated. I went back to stock rom, gone through all the settings and still no LTE. So I'm wondering is it possible to fry the LTE receiver chip on my phone from over use? Are there similar incidents out there? Is there a fix?

If you dial *#*#4636#*#* do you get the testing menu? If so, go into Phone Information and check you are set to LTE/GSM auto or similar.
Otherwise, maybe you have flashed an incompatible LTE modem?
On my K3 Note, I can't pick preferred network mode on ANY rom/firmware.
I've tried everything, but it always sets the default preference which is 4G>3G>2G.
What I need though is permanent 2G and I can't set it this way. (4G signal is weak on my operator and then it keeps switching between 4G and 2G over and over)
Is there any way to entirely disable or block 4G on a phone so it will never set that mode again?
Any help would be appreciated!
Any help guys? No one knows what could be the issue?
I tried using the *#*#4636#*#* code and set the "GSM Only" but it still doesn't work.
Is anyone else having the same issue?
Edit:
Also what I've noticed is that while using CyanogenMod (atm), it stays on 2G until I turn the screen off. Then it goes back to 4G.
After turning the screen back on it then goes back to 2G again.
same problem here when dialling number it said invalid MMI code and when switching to 4g the other network appear no signal.. hope someone here have solution. i try several roms but same problem issue.
Well after a lot of fiddling, it seems it works on the stock firmware, but the mobile operator as himself has quite troubling network.
But I think we are slowly coming to a conclusion..
Hi All,
First time poster with an unusual problem. I live in Australia and have a Samsung Galaxy S5 SM-G900F which is the European model. Up and till recently I was getting Telstra 4G reception. Now all of a sudden I'm only getting constant 3G reception. I have confirmed that there are no 4G network repair/maintenance/upgrade issues in my area. It was only in the last week that I noticed the constant 3G reception so I can't really pinpoint a specific incident or exact date as to when it actually started happening. Here is what I have tried thus far:
Phone restarts, changing network settings and switching to flight mode.
I've confirmed that the phone network is set to LTE/WCDMA/GSM (auto connect).
I have done numerous hard resets, cache wipes, Dalvik cache wipes, drive wipes, etc.
I have rooted and unrooted the phone numerous times.
I have tried several different stock and custom ROMS.
I have tried 4G SIM cards from other phones.
Tried numerous network switching apps.
NOTHING WORKS!
I always love to tinker with my phone so I'm always looking for ways to improve the phone's performance. It may be that an app (battery improvement/tweaking type apps) I installed somehow changed the network settings but I would have thought a million hard resets would have sorted that all out but apparently not. At the moment I'm running a rooted stock Android 5.1 ROM. I've tried stock Android 4 and 6 as well with no joy.
Here is the unusual thing. When I put in another 4G SIM card into my phone the network still remains on 3G but as soon as I put my SIM card back in 4G magically reappears. It's bizarre. At least I know my phone can still get 4G. You would think that would solve the problem but it doesn't. When I am in an area where the 4G signal is weak the stronger 3G signal kicks in as it is supposed to. When I get back into an area with strong 4G reception the phone remains stuck on 3G and no matter what I do it won't go back to 4G unless I go through the convoluted process described above.
I am all out of ideas. I think I have tried everything possible. I've trawled the web and I appear to be the only person in the world with this problem. I don't know if it is a software or hardware problem with my phone. My SIM card works in other 4G phones so I don't think it is part of the problem. At the end of the day it's not a big deal as 3G is fine but I'm just one of these people that has to fix a problem. Worst case scenario I'll probably upgrade the phone in the next 6 months.
Any suggestions or tips other than what I have listed above would be greatly appreciated. Thanks in advance.
