[Q] network mode changes by itself. Should it do that?

Im running cm 10.1.2 it works great I live were tmobile has lte. so I flash LTE radio and that works great. my apn is tmobel us LTE and my preferred network mode is lte/gsm/wcdma. Sometimes when I drive outside lte coverage zone or in on a weak spot my preferred network mode will change to csm/wcdma. Is this normal? I was driving and I just lost signal the other day Im guessing this is why. I got a screen shot of a app that shows I get lte or hspap with lte/gsm/wcdma. Should I not get both hspap and lte with this setting. Im guessing the phone could not get lte so it changed the profile? Can it do that?. When I was out of the coverage area tried to change it back to let/gsm/wcdma but it defaulted to csm/wcdma.. On reboot it defaults to lte/gsm/wcdma. so i know its working thanks for reading my thread.

I'm pretty sure that is normal. My phone does the same.

So when your phone changes profile when it gose into a lte zone dose it drops signal or any thing?
I want to say mind dose for a second as the profile changes then if I go back into a LTE zone it will change back. But im not sure as I have only been running this build for a few days and I mostly stay in a LTE zone.

Yes basically disconnects for a sec then changes.

Just wondering why that is? does lte/gsm/wcdma not support hspap? Because my app screen shot told me on that profile i get hspap and lte .

I'm not really sure. But I do not understand why the nexus 4 handles this Network change so slowly. It's annoying at times.

[Q] Get LTE speed on cyanogenmod running on Galaxy Sr

So I have a Galaxy S4 Sgh-i337m (Canadian version) that have a custom recovery(clockwork touch 6) and is rooted. On that phone I have cyanogenmod 10.2 and I've been trying to get an LTE speed without success. I've seen the posts that tell me to change my apn but it haven't work. Currently when I switch data on I either get 4G or H+. I made speed test and the maximum I got is 10MBPS normally it should be around 30 to 75MBPS. So can someone help me get LTE speeds here's a photo of my current APN?

Could be a bunch of issues. Is the network mode set correct? I have noticed at times it is set to 4G to save battery. I have had times after flashing a ROM not connecting to the lte towers until after making a call. Another fix is resetting to default in apn.

Unless they've added an LTE symbol...on CyanogenMod 4G means LTE.
On touchwiz when it displays 4G its pretty much H+, Samsung just likes to make it look better
However you are right...your speed tests aren't lte speeds

When you see 4G on the status bar go to settings >about device>status. Network type should say umts% for 3g, hspda% for hspa+ or lte% for LTE (The % represents a frequency). Then you'll know for sure.

Yes it means that you have lte. The reason why your dl speed is so slow could be your reception or it could be your on wifi

[How to] Disable LTE or 4G

This is useful if you have a weak LTE signal or just don't need it always on. I found this tutorial on a different website for another galaxy phone and it works on the Note 3.
1. Turn off your phone and take out your sim card.
2. Turn on your phone with no sim card and wait a minute or two for it to turn on and settle down.
3. Go to the dialer and dial *#2263#
You should see a menu with band selections. The current setting is "Automatic".
(You have to use the menu key to select your options by using "Key Input" to type the number you want)
If you switch to "GSM All", you will be EDGE (2G).
If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Power off the phone again and put your sim card back. Upon reboot you should see your new setting in effect.

I get a service mode that says rat selection is restricted...
However *#*#4636#*#* will allow you to select whatever band you so choose. Although lte only doesn't allow voice calls

Thank you inmotion! This code actually worked better for me on my Samsung Galaxy Note 3. I didn't even have to pull out my SIM card or reboot. Just dial in the code, go to Device Info and change the preferred radio network type. It changes the radio on the fly in real time, and can be seen at the top.

Since Android 4.3 and on the option to disable LTE/4G has been removed from all AT&T Android devices.

Actually it was before that. Could not do it on my note 1. Would always get RAT restricted. This was on at&t. Other networks were able to use those codes and make the switch.
Sent from my SAMSUNG-SM-N900A using XDA Premium 4 mobile app

1. Download the free Phone info app from the Google Play Store and install it
2. Choose the Phone Information tab and notice the "Set preferred network type" option at the bottom, marked with an arrow at the right of the drop-down menu
3. Tap on the preferred network listing currently in use, and choose the "CDMA auto (PRL)" option from the drop-down list
4. You should be now maintaining connection to only Verizon's 3G network, and whenever you need to use data, you can switch back to LTE for the duration of it
There are numerous other apps and widgets at the Play Store that claim to do the 2G/3G/4G switch, but many users on Verizon have confirmed the Phone info app to be the only method allowing them to reliably turn off the 4G LTE on their Samsung Galaxy S IIIs.

Getting ready for 4G?

HI, the three network in the UK is rolling out 4G this weekend, what rom do I need to flash my nexus 4 with to get it working ???!!....I wan't super fast lol !!!!!!!

I think it's only starting in like 3/4 cities if your lucky enough to live in one of the cities. Also nexus 4 only supports one band on 4g if your also lucky enough for three to be using the supported band.

itll work on the n4 only if its band 4 lte, and no other frequency for lte. and its not about flashing a rom, its about flashing a hybrid radi, having the right apn, and changing the phine info to lte/gsm. there are threads that explain how to do it.

Yes I live in London.....but since updating to the latest 4.3 I can no longer select 4g LTE in the service menu. How would I find out if three is using the correct band !????

for 4.3 the option is in the phone menu, . and you need to ask them what band they are using.

it goes back because you need to use either the .27 hybrid radio or the .33 hybrid radio. google disabled lte for 4.3, and you cant enable lte in the settings unless you are using one of the hybrid radios.

nice rationalization, but not true. the chip works great, everything works. and since switching over to lte permanently, ive been seeing 6-7 hours screen on time regularly. imagine this, when you download things it takes time for it to finish downloading, especially large files. the slower data speed, the longer it takes. the longer it takes, the more battery is wasted. on lte, i average about 30mbps download speed, so downloads finish in seconds. so less battery is wasted. i download 2gb games from the play store in about 13-18 minutes. the newer lte chips are much better on battety than the old days, better than hspa+, hspa, 3g, and 2g.

How can that be possible ? The LTE chip in the nexus 4 has no antenna or amplifier :/ hmm I'm baffled

Battery life is the same with LTE enabled. My N4 has it enabled my wife hasn't let me to it to her's yet and our battery life is the same, but my data is much faster than her's. I get LTE signal with my N4 in the same places as I do with my Galaxy Tab 2. So I would say it works perfectly fine. Yes I am on T-mobile in case anyone was wondering.

3 UK is going to use LTE band 3 and 20 only, so the nexus 4 will not support it (unless Google is going to release a Nexus 4 LTe version, which is pointless because you should get the Nexus 5 anyway.)

Many people are using LTE on their Nexus 4 including me, it only work with LTE band 4.

4.4 and Non-VZW carriers

These issues apply to T-Mobile users installing the current build of 4.4 (and possibly other GSM carriers but I don't have an ATT SIM to test). Motorola is aware of the issue. I read these forums pretty thoroughly and I've been answering these questions all over so I figured I'd just put them all one place. Issues as follows:
- Devices with the LTE radio active cannot send SMS
- Devices with the LTE radio active cannot send MMS (Carrier/Settings dependent)
- Devices with the LTE radio active cannot make phone calls and instantly disconnects on call attempt.
Urban Legends:
- Stock tethering does not work - I have personally tested on TMO and know it does work. Yer doin' it wrong.
Fixes
Easiest fix for now if you're on a device running 4.4 and want to... you know... be able to use your phone... is to use phone information and switch the radio mode over to GSM Only (not the auto one). This fix is a little finicky because if the phone realizes it's not running in the mode selected on your mobile networks screen it will override and turn LTE back on if you haven't selected UMTS only.
Full steps are:
Mobile network settings - Change network mode to LTE/GSM/UMTS
Mobile network settings - Select network UMTS Only
Install app linked below
Open Phone Info and select GSM Only
Phone info apk for sideload - http://www.mediafire.com/download/284l17ry2ok1yuk/Phone_info_1.3.apk
I'll update this thread as I discover more issues or as people post issues that can be replicated below.

Thank you. Finally I got the LTE turn off.
I gotta switch the mobile mode to LTE/UMTS/ gsm and select network as UMTS only. Then use phone info choose gsm only.

It was selecting GSM Only in Phone Info. Switched it to GSM auto (PRL) and I got HSPA+ back.
but Seriously dude. thanks for this info. I was tired of using my Moto G while my MAXX was just collecting Dust.

Edited the OP for a more clear fix. Thank you to vuphongkkk for pointing out the UMTS only.

I'm on T-Mobile and live in an HSPA+ refarmed area (NYC), but there are places I go on a regular basis that aren't refarmed. I set it on "WCDMA preferred" and voila, I have both 2 & 3G connectivity, with preference given to 3G.
I can't post links, but this XDA thread explains it in more detail I think: ... showthread.php?t=688492

Vodafone confirmed for anyone wondering.
H+ for UMTS only,
Edge for global.
No Sim adjusting at all

Just popped a sim in today. Getting LTE but really hating the call fail bug. Gotta place the call twice repeatedly to get it through
Maxx'd out Kit Kat

Update: Having major glitches when running LTE, pretty deal breaking for a full switch to tmo right now. Eagerly awaiting the new OTA to see if it fixes it. Seems to have major issues on the HSPA/LTE handoff. How did it function prior to 4.4?

On 4.2.2 was working fine, the phone just switch from LTE to 3g itself when you need to make phone call. But I had problem on 4.2.2 that if I connect to WiFi then it'll take awhile to get the LTE back. Normally an hour after out of WiFi range

You can uninstall it if you want. It's extremely small though so no reason to do so unless you just don't want to see the icon. Uninstalling will NOT reset your settings.

Thanks! I messed myself all up though.
In android mobile network settings should I have network mode as global, LTE/CDMA or LTE/gsm/umts?
If its LTE/gsm/umts do I still use gsm only under select network?
And if I leave phone info installed do I have to change anything on there for LTE to work? Phone info seems to change the network selection in the app on its own so I just stopped messing with it. Thanks and sorry to be a pain

4.2.2 rarely get LTE data. Choose network mode as LTE/gsm/UMTS . select network as automatic. Don't use the phone info. If you already use the phone info app in this thread then use it again to switch back to LTE/gsm.. Or the option that has evething.
