T-Mobile H/E connection

So i finally got my nexus 4 and I'm on T-Mobile network and noticed that at work i notice my signal is constantly switching from H (HSDPA+) and E (edge). It's kind of annoying since edge data is very slow. Is this a common issue with the n4? When i get H signal, i have two bars so i don't think it is being boarder line signal. Please let me know, really hope i don't have to return this sweet phone!!!!
Are there any updated radios yet that i can try? I know with Vzw galaxy nexus radios helped a lot with 1x/3g/4g switching.

Any info on this? I know what the symbols stand for, however why can't this hold a strong HSPA signal for more than a minute without switching to edge even if the signal is 2 bar? Doesn't seem right

check your APN's

It happens to me as well but its not just my nexus 4. It happens to my iPhone and my brothers HTC one v. Its just that we have decent to bad signal at home. Signal gets spotty sometimes.
So if you're at home just use WiFi and leave data off.

Thanks for the reply, any info how how to change the apns and what the best ones would be? I have been reading many people say their n4 idles with 3g and then ramps up to hspa when it calls for data usage. Mine doesn't act like this and just randomly drops to edge

Mine stays on 3g and only switches to H+ when I use data (custom rom icons). I think its normal

There is an app that takes you into the menu where you can choose network types, this is what is used to turn on LTE. Go in and put it to WCDMA Only, that should make it stay only on H+ and not go to Edge.

[Q] s4 GT-I9505 missing DC-HSDPA/LTE

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.

[Q] Odd LTE Signal Swap Issues

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 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

Network coverage issues or device ?

I'm having some problems with my G2 - I don't have good 3G coverage especially inside and my phone keeps dropping calls when on 3G. It seems the software doesn't reconnect that fast and doesn't switch to 2G when the 3G signal is too low. Is there any way to change the preferred network and stop the device being so agressive at keeping 3G connection?

Settings/networks/tethering & networks/mobile networks/network mode/GSM only.

I already know that. It is the most unhelpful advice to give. I have to constantly go into settings and change that? No way. It isn't in the notification toggles which is really odd. Any idea how to add it? I feel my G2 has some radio issues.

Well if you're going to be like that then there's no wonder why there aren't a stream of responses on here with people trying to help you out.
Just remember, you're the one with the problem, so you may want to be a little nicer to those that try to give you help.

I'm sorry about that, but there wasn't a stream of responses in the first place. He was just stating the obvious, and the obvious is that the G2 doesn,t have a shortcut to switch between 2g and 3g. I'm just trying to figure out a way to do that, but all the apps that claim to do that and they are too many of them, just don't work. I'm thankful for any help, don't get me wrong.

There isn't a solution as simple as hitting a switch, but you can try the following:
Go into your Dialer and tap in *#*#4636#*#*
This will take you into the Testing Menu
Select 'Phone Information'
Then about half way down you will have a drop down where you can "Set preferred network type:"
This will allow you to choose whether to use 2G or 3G, but more important to your case you can choose how it will react if signal strength is low.
You probably want to select something like "GSM auto (PRL)"
Bare in mind though that this option will reset itself back to original setting each time you reboot the device.
Now I don't know if this will solve your problem, but it is worth testing out.
Here's a list detailing the main available options:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best.
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

Wnderful setting.. amazing speed... performance of handset increased like rocket..
Thanks a lot...

Hi,
After dialing *#*#4636#*#*, it shows up the menu.
But i am not able to select Phone Information option. It says "This application does not work on this device".
Phone info: LG G2 D802 - Rooted - PowerG2 2.1 ROM.
I face frequent network signal drop, I tried CloudyG2 ROM also.
Thanks !

4g / LTE Toggle / radio control

At work the 4g LTE signal for ATT is very poor in the building, but we have 4g repeaters for ATT to fix this issue. Unfortunately, phones are stubborn and like to stay on 4g LTE despite having 1 bar of signal vs full signal with 4g. I had this same issue on my iphone 5 but was able to easily force off LTE while i was at work and have a steady, reliable data connection. My Note 4 seems to have the same affinity to wanting to be on 1 bar of LTE, but I cannot figure out a way to toggle / force LTE off and just use 4g. Anyone have any ideas? Anyone know of an application I can use to resolve this issue?
Thanks

try settings...more networks...mobile networks....network mode....It should be in there..I have the sprint model so I don't know for sure...but that is where mine is....hope this helps

Unfortunately, there is no option for Network mode on the ATT version. I wonder if this has to do with voLTE....
I did find a backway to the network mode via *#*#4636#*#* but I am unsure of what I should be setting to "disable" lte while I'm in the building at work.

I think I've sorted this out now. If I change LTE/GSM AUTO to WCDMA preferred it seems to immediately switch and hold onto 4G. I do have to change it back. Maybe I will write something so I can quick toggle this since nothing on the app store seems to work.

hi,
If you are rooted ? You can use an xpose module called Intelli3G
I use it on my phone ,works 100% and switches smoothly/fast between eg 4G..3G automatic
eg if my data is of its on 3G as soon as i switch data on /wifi it changes to 4 G
For interest sake ,here is a link to market ,you can read desciption what it does ?
