I seem to be having the strangest LTE / 4G signal issues with the S4. I get 4G fine but when i leave a 4G area it drops to H+ or if the signal on 4G is weak it drops to H / H+ during this transition i am left without any signal for seconds to minutes as it switches.
Is there any way to find out what my LTE modem version is as i know my GSM one?
I am not too sure if this switch is normal to be lost without signal as GSM > H > H+ works fine and i still have signal

Check your baseband version and try to flash through ODIN the right one for your location

how do i do this? i can only see GSM modem not LTE. i know both versions maybe different
Mate the baseband of your phone is the same for both the gsm and lte configurations of your phone. If that won't work you can still check your carriers vpn configurations to see if there are correct

**If you are having the old bootloader XXUB flash GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUBMH1.tar file with odin by selecting phone.
**If you are having the new bootloader XXUD flash GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUEMJ5.tar file with odin by selecting phone.
So this means that even if it says the LTE modem is different to the GSM modem you are saying that the help about the modem for GSM and LTE is in fact the same?

From my knowledge you cant flash anything you like.You need to flash the correct modem for your region.Whats the version of your bootloader and your country so i can link you the correct file
I am experiencing the same thing, the switch from H+ to 4G doesn't drop the actual signal from the network whereas from 4G to H+ the signal drops leaving me no service at all for a few seconds.
I am starting to think that this is the normal behavior because it's like this since I got the S4. Oh and I have the latest modem for my country as well if that helps.
Perhaps someone with knowledge on how the modem works can chime in?

Thanks chickentuna for your reply
Ok the 4G works perfectly fine in Hong Kong, London but as soon as i leave london and go to areas with 4G but low signal, i get the horrible loss of network until the phone does a search. I think its more network / phone related but would just need to learn to disable 4G out of the main cities.
asbanoglou thanks for trying you can flash any modem but whether or not it will work is another matter. I understand bootloader, different modems and csc i am looking for something a little more non generic. I first assumed this was the firmware / modem combo but after trying multiple ones this does not seem to be the case unless there is a long standing issue with the S4 and LTE.
As a future note to get the modem versions you dial *#1234# . More > About does not give you the full picture but thanks for those who tried to help

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.
I am unable to connect to GSM only network ... My N4 while roaming out of city limits doesnot catch GSM signal .. it only works with 3g signal .. I noticed this issue just a week back and it has kept me worried .. Can someone point me to a proper direction with regards to this issue.. I flashed the latest available radio JDQ39E but still no luck.. there is no GSM signal.. My nexus 4 has the latest 4.2.2 rom in it.:crying:

Where are you at? Which network? There are areas (rare but there are) where t-mobile is wcdma (3g) only.

Hello guys,So im with three.uk they dont do LTE yet but they r about to roll it out very soon however they do DC-HSDPA and im in area where i should be getting it sadly im not getting it for some reason top of the screen shows only H+(mostly) sometimes H and 3G. If i go to connections->More Networks-> Mobile Networks -> Network mode i only get WCDMA/GSM(auto connect) or WCDMA only so this is what i get. I was reading that there is some problem with s4's shipped from korea and people advice to flash to unbranded stock well one was australian so i even flashed to australian firmware even to getman firmware so far no luck no lte in options not detecting DC-HSDPA just after flashing to getman/australian firmware i got an extra option in network mode and it is gsm only plus the other two i said before. So my question is how i could get this DC-HSDPA working and what indicator top of the screen will show instead of h+ will it show DC ? i was trying to find answers but no luck so far please help me outKind rengards Martin

Hi,
H+ will still display on your signal strength indicator, as DC-HSDPA is just a variant of the HSPA network system. to force the internet to always connect to a higher speed network set it to WCDMA Only.
There is no DC-HSDPA or HSDPA in the network selection, it is tied to the WCDMA system.

Root Explorer (or another), and go to data/property.
select persist.radio.lteon , edit it with a text editor and change the value from false to true.
Save changes, reboot and enjoy
bye to all.

I can't answer your question because there's no 4G signal where i live , sorry ....
it was only the solution for who has this problem:
If i go to connections->More Networks-> Mobile Networks -> Network mode i only get WCDMA/GSM(auto connect) or WCDMA only so this is what i get.

This isn't about 4G? It's about DC-HSDPA.

have problem after open line
Hi is anybody here in Philippines who have the same issue with me.
i have samsung galaxy s4 i9505 which is smart network lock.
i brought my phone to technician to let it open line,
it was then opened to my globe line but my problem is i barely get an H or H+ data connection,
when i went back to the technician and asked the problem i got after they open it, he said its normal..
am i getting the right answer it is normal to have it for opening other network line? thx.
I have N9005 in the UK on EE network. We have 3g, H+ and LTE 4g. In my area I don't get LTE so that os irrelevant.
When I make a call, sometimes I can use data on the phone. For example, whilst on speaker phone, browse XDA.
However, very often, I have no data at all during the call. No 3g, no H+.
The problem is not data signal, as when the call ends I can easily use data.
So, does anybody have this issue?
Also, can anyone explain why?
F. Y. I it is GSM in the UK.

if you have a data signal while on a call your in a H+ area anything lower the data signal drops for the call

yep basically only a H+ signal supports voice and data together. i had it since sgs2 just sort of learnt to put up with it
My understanding has always been that only Three network could use data during a call. Unless I'm wrong.

does your wireless carrier support phone call and data usage simultaneously. You probably need to call your wireless carrier and find out. Goodluck

YOU don't get LTE because N9005XXUDMJ6 firmware
My one is same, wait for N9005XXUDMK2 firmware or just make clean instal with odin v3.09,Then you will get 4g/lte,
Yesterday i had same issue with calls,,when i make call or receive call data signal was gone its all related to N9005XXUDMJ6 firmware Just install N9005XXUDMK2 then everything will be fine....
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.
