[Q] LTE signal drop - Nexus 4 Q&A, Help & Troubleshooting

Hey I've tried searching for a thread for my problem but didn't find anything so here it goes;
Still on the old radio, whenever I choose "LTE Only" on Phone Info. I get good signal (4G logo) for about half an hour, and then I notice a complete drop in signal. The phone simply doesn't work; no calls, no data, no sms...
Anyone familiar with this issue? Weirdly on the WCDMA signal I never have a signal drop (H+).
Basically I've never been successful in getting consistent LTE signal for an entire day since the purchase of this phone. Anyone know of a fix?
I'm on Telus in Canada so APN settings are the same as regular HSPA+
Thanks!

Bump. Any help or pointers would be highly appreciated!

Use the LTE/GSM auto setting. LTE Only will only rely on a strong LTE signal, and not drop down to any of the other networks if it needs to. I use LTE/GSM auto and haven't had any problems with losing connection. It switches down from LTE to H+ when it needs to.

Maybe your carrier decided to cut off support for lte on nexus 4?
You could try reflashing the radio to see if it cures your problem.

What provinces are you guys in? Im trying to get LTE to work on my Nexus in Calgary and not having any luck so far. When i switch the the LTE/GSM signal nothing happens. Is there any other radio flashes that need to be performed to get the LTE signal.
Checked with Telus already, the V3 sim cards can do LTE.

Network dies when I turn off 2g

Anyone have this problem? It happens ever time

Hmm.... seems like your phone might be in WCDMA mode only... It should be in WCDMA-Preferred since you plan on using 3G and 2G
Go to your phone dialer and dial *#*#4636#*#*
and Diagnostics Menu should come up..... Go to PHONE INFORMATION.... Scroll down and Set Network Type to: WCDMA Preferred
see if that helps...
Thanks for the reply i am on tmobile and it is defaulted to GSM. Will changing it be any different than GSM?
my phone does that as well right now at home even though i have it on WCDMA preferred, t-mo has been having issues with their 4G towers and their DNS servers lately that has been affecting many people with newer phones/SIM cards and in 4G areas, t-mo has not released an ETA on a fix but i have been dealing with it for a month now at my home and i am about ready to switch carriers

Nope, it'll still be the same. WCDMA-Preferred means that then phone will Prioritize 3G/4G signal over an EDGE signal. So If you are in a decent 4G/3G coverage the phone will set itself into 3G/4G mode... and when you move into an area where you have a weaker 3G/4G signal...t han the phone will be in EDGE mode.
Keep in mind that if you're referring about using WCDMA Preferred in a 3G/4G coverage area - but only 2G works - then you have a network issue. This isn't so much a device issue as it is a MSISDN issue on the network or a potential tower issue.
If you get no signal on 3G/4G and signal is there on 2G - check your coverage first - then if coverage shows you should have 3G/4G, call TMO and let them know, they'll need to do a service request or trouble ticket based on the location and breadth of the issue you're having.

[Q] Nexus 4 Radio - No 3G/HSPA Signal

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
Guys....even I had the same problem.....but was able to solve it.....
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

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.

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

Network mode problem

Hello.
I have a note 3 n9005 and when the network mode is WCDMA/GSM or LTE/WCDMA/GSM, my phone stays on GSM often. 3G signal is good in the area, and when I check my friends' phones, I find out their phones are on 3G network but mine is on 2G.
When I choose WCDMA Only, phone registers on 3G network and works without any problem. But switching back to auto connect, cause the phone to register on 2G again after some time.
So is there any configuration that tells the phone to stay on 2G if 3G signal is weak?
Please help if you can.
Thanks in advance.

The cell tower does this by signal quality, and most of the time distance dictates quality. I myself have asked around for AUTO 3G/4G only, but it seems like a subject where nobody has done any research.
Does your 3G signal differ from WCDMA only compared to Auto mode? If so, try updating to a newer firmware, could be a modem/baseband issue that may has been fixed in the mean time.
Technically it should grab the highest network of the three. So LTE has priority over WCDMA, which has priority over GSM. So even if WCDMA has one bar, and GSM 4, it should grab WCDMA until it completely loses that signal.
Have you tested another SIMcard in your phone? It may very well be a SIM problem.

You say it is fault of the cell tower?
So why phones of my friends are ok about this issue and register on WCDMA?
I flashed 3 different lollipop ROMs but nothing changed. ?

Yes. That's exactly what I expect my phone to act about switching between network types.
I never tested another SIM in my phone. So I will check that as soon as possible. I will post the result. Thank you.

Signal problem theory/research

Hello, i live in a relatively small town where my service provider has very poor 4G signal. but pretty good 3G signal. With the Axon 7 i have a lot of signal problems that i didnt have with any of my previous phones, where outdoor signal is pretty bad and indoor signal is almost unusable. It also connects almost exclusively to 4G, and in contrast all of my previous phones connected almost exclusively to 3G. Over the last weekend i traveled to a major city where my service provider has very strong 4G signal, and the signal problem was almost non existant. I even had signal in places where other people with the same service provider did not. So my theory is the following, assuming that the hardware (antenna) used for 4G and 3G is the same, it may not be a hardware problem, but a problem with the software having a hard time knowing which band/signal it should connect to. It seems that in my case it prioritizes 4G signal and the cost of a VERY unstable cellphone service. This is also assosiated with the fact that when it connects to 3G (incredibly rare), the phone goes inmediately from 1/2 bars to 4/5 bars. I also changed the SIM configuration to leave LTE out, but either for a visual bug or a software bug, it keeps connecting only to 4G. So could this be the problem that me and a lot of people in low 4G signal zones are having? Is there anyway i can force the phone to connect exclusivly to the 3G signal to test if that is indeed the problem?
Regards!

Without knowing which model Axon 7 you are using, where you are using it, and who your provider is, there is little anyone can do to help you. All I can say is that it helped me A LOT to go into settings and turn off
VoLTE.

U model last update, using it from Argentina, and the provider is Claro. I have LTE disabled in SIM confg as i already said and VoLTE turn of as well but the phone keeps connecting to 4G no matter what i do, even if i configure it to only GSM
I don't think its a matter of position or provider (version could be if different software is provided), but a general issue with the phone and band/signal interpretation coupled with the apparent innability to go off 4G
Refards!

ok when it connects to LTE it says "4G LTE". The 4G that you are getting is probably HSPA or something. And we had someone on here a few months back using Claro in Argentina and they had to seek answers from their Claro

If "4G LTE" is 4G and "4G" is HSPA, when only a "G" appears, what band am i connecting too? Its still pretty weird that im having major signal issues in my town, but when i go to a big city my signal is even better than other phones, it seems inconsistent with the whole "bad hardware" theory. I talked to Claro and it seemed like from their end it was a non issue, can you point me to the thread to see if he got it fixed somehow?
Regards!

/Trolling a bit/
I'm always LMAO when I hear US people talking about that 4G scam (which is H+ for real btw)
G is for 2G
E is for 2G+
3G is 3G
H is 3G+
H+ is 3G++ (an intermediary protocol up to 42MBps)
4G is LTE (up to 150Mbps in the EU most of the time)
4G+ is LTE-A (which is available in most of the EU, SK & JP) - up to 600Mbps, 200MBps in most tests
I've not heard of an app that could modify the way the phone "clings" to 4G LTE, since that might likely be the modem firmware doing it on its own.

Then this is even weirder, because is G is not 3G, but 2G it means that the phone NEVER connects to the major band that all of my previous phones and Claro users connect to. Is there anyway to force to only connect to 3G?
Regards!
i have the G european model, in my town i have bad lte signal 1/2bar, when with my previously xiaomi mi4c was got 4/5 bars (maximum). In the big town i have got in the most of cases 4/5 bars. I think the "signal problems" are relatives of a lack of somehow software. i told this because i've read with the china model with the last updates an improvement of the signal reception of the phone.

You can however force a specific protocol indeed, but you will lack the ability to autoswitch networks. Just download 4G LTE Switch (here) which is a glorified secret code dialer. Just click on prefered network and change at your convenience (4G LTE only, WCDMA only - H+ - and so on). Remember that if you force 4G LTE in an area in which you have no coverage, you won't have internet, and no 2G/3G fallback (so no texts, no calls)
I don't know if this is the same problem, but my wife has an iPhone 6+ and I have an A2017U on B29 stock root. We both use the same network (Movistar Mexico) and while her iPhone often registers LTE, my A7 often registers 4G or even E in the same place. The A7 is receiving the same bands but appears to be "choosing" or locking into the slower protocols more often.
EDIT: NEVER MIND… an xposed module was messing with my network settings. Fixed it. Now I get LTE right away.

Nokia X6 2018 defaults to H+ connection on Cricket

Hi guys,
I just got a Nokia X6 on Android One shipped from China and for some reason it defaults continuously to H+ instead of LTE on my Cricket network. On my Network Type option in the Setting In only have 3 options 2G, 3G and 4G and I have 4G selected, but still H+ is being used by default even in areas where I used to get full LTE signal.
I have tried however to get into the Android Testing Menu (by dialing *#*#4636#*#*) and change the Preferred Network Type to a few options like LTE/UMTS auto (PRL), but for some reason is the H+ that is picket all the time. even in areas where I know the LTE signal is strong. If I select "LTE only" from that menu, then I'm getting on LTE but as soon as I go into weak signal region, the signal drops completely, while not the same thing I can say about the other option, when the H+ connection is present in the same weak signal area.
Another thing that I see in the Android Testing Menu is that my VoLTE provisioned option is Off and I can turn it on.
Do you guys have any ideas on how can I get this device connected to LTE when the signal is strong?
I have a Nokia X6. I put two SIMs into it, both show 4G.
I have some problem to connect data or mobile internet. Grammen phone provider.
I was ready to purchase one, however, was curious if this would work on t-mobile. If so, would the Wi-Fi calling work?
Did you already checked if your 4g network band compatible with your phone?

So, have you solved your problem?
If the ROM of your phone is "CN" you could try to flash the phone to the global ROM 2_29(WW) or wait for a new update of the firmware. You haven't noticed the firmware's version. Have the phone got any updates?
I just returned the phone and got an LG G7 instead. The X6 that I was using also had a problem with Bluetooth as I was never able to turn it on.
Manually switch the preferred network type.
I am using the latest Stock Android version on Nokia 8 and struggled with this issue too. I tried everything I could possibly do.
The simplest answer is to go into network settings and select 2G, give it a minute to find it. Do it for 3G too. Give it a minute to find it. Then 4G, same thing. Finally select 4G as preferred network type and that should do it.
It looks like the default preferred network type is 3G from the factory.
guys i cant even access my mobile data connection can anyone tell how access it
thanks
