I've been testing following handset models for AGPS for Emergency Services (providing location for emergency services): J1, and J5 but also S4, Tab4, Note 10.1, A3, A7, S7, S6, NOTE 5 and S3 Neo. All of them have GPS and support Assisted GPS (A-GPS).
In these tests I send Network Initiated Location Request to a handset either in 2G/GSM, 3G/UMTS or 4G/LTE. Knowing that they all support A-GPS, it is very odd what follows. Most of them report:
Reason for Failure
- "Measurement control failure" (error code: unsupportedMeasurement), or
- "Position method failure" (error code: methodNotSupported / System Failure)
Only NOTE 5 returns location in GSM. All the other RATs fail and all the other devices fail in all RATs. I know that the Spirent (ULTS 8100-A750) testing setup is working correctly as I have also tested many other phones e.g. from Huawei and LG, and they do return location. And that Samsung NOTE 5 works in GSM.
What could be the issue?

The Samsung Galaxy Note 10.1 - 2014 edition was released back in October 2013.
For those of you who have got down this awesome little device - CONGRATS! I got an International (factory unlocked) version from Singapore.
Once I brought it down to Sri Lanka and put in a 4G supported sim, things started getting weird. My 4G didn't work The status bar only read H+ (which means WCDMA and not LTE)
My LTE carrier (Sri Dialog) said that although the sim was 4G ready, the device may have locked on to another 4G band since it was from another country.
I used a little Debug application and found out that the Note 10.1 was locked on to HSDPA 1200 Band 1, whereas the carrier supported 4G on LTE 1200 Band 3
I tried going into Samsung's little backdoor called Service Mode, however Service Mode appeared not to work in here
(Check the comments to learn how to easily access Service Mode on all Galaxy devices)
Turns out that a couple of Note 10.1 2014 edition devices had this issue, where Service Mode can't be accessed. Service Mode is the easiest way to resolve a network problem.
Well want to know the solution? Follow these steps :fingers-crossed:
1. Root you're device using Odin. First uninstall Samsung KNOX. If you don't know how to do that, just make sure that SuperSU is installed as you're root app. Follow this root tutorial: dottech.org/148205/how-to-root-samsung-galaxy-note-10-1-2014-edition-guide
2. Next download Advanced Signal Status from the Play Store. Just follow this link: play.google.com/store/apps/details?id=com.cc.signalinfo
3. Open Advanced Signal Status and go to Advanced Settings > Device Settings > Network Selection and select 'LTE/GSM'. Here GSM means HSDPA/WCDMA. You will be asked to grant root access to the app during this process. If the app crashes during the first launch, just lauch it again. After all, it was built for phones
Congrats! :laugh: You're device should now work on 4G

Service Mode
Kind of digression, but how do you go into the Service Mode in Galaxy Note 10.1 2014?

There are various codes that you have to type in to you're dialer in order to access Service Mode, however you can use the Service Mode Shortcut app on the Play Store which makes this much more easier. Apparently Samsung has disabled Service Mode for some Note 10.1 (2014 edition) devices.
Download the Service Mode Shortcut app by following this link: play.google.com/store/apps/details?id=com.kabasoft.util.servicemodeshortcut

I have the same tablet - bought from Amazon and using Straight Talk as my carrier. I'm not willing to root in fear of bricking my device. Is there or will there ever be another route for me to get LTE?
I can't connect to AT&T, but I get hspa and hspa+ through AT&T microcell... which I never signed up to get.
Great app! Tried this on my P605 (Australia). Auto selected in the options was LTE/GSM auto. Changed to LTE/GSM/CDMA and made no difference...turned on LTE only and did the OOKLA speed test just outside my house and it performed 4 times better! It should be said 4G in my area isn't strong at the moment.
So I get LTE but as soon as I get on a call signal goes to H and I cant use data/apps while on the call. Am I using the wrong APN settings, or wrong radio maybe? Any settings help would be great, or if you can confirm also. Thanks.
Mine nexus 6 did same thing. I'm not sure that the data still work or not but everytime I on call I see LTE Icon change to H like you said
It's one of 2 things.
Either VoLTE is not turned on on your device
Or ATT does not support VoLTE in your area.
First one is fixable. Second one is not.

AT&T doesn't support VoLTE on any phones that aren't sold by them.

Then that would explain that I would think
LTE is data only, so when u go on a voice call it will got to hsdpa or 3g bc that is voice and data, so it is normal

Please don't spread information that's no longer the 100% truth. AT&T, Verizon, and (for a while now) T-Mobile offer calling over their LTE network, dubbed VoLTE (Voice over LTE). It allows voice packets to travel over the LTE network instead of legacy/3G and older networks.
The way the standard it set up, devices made more recently have software and hardware support for it, but as carriers have certification processes for their network, not all devices work cross-carrier. Most notably, iPhones (bleh) work cross-carrier because of the way their network configuration is provisioned (device identifies what network it's on, and downloads carrier configuration for that particular network). Some Android devices work cross-carrier (Nexus 6P and 5X), but the manufacturers of Android devices designing unlocked devices for some reason aren't certifying on AT&T, maybe because of cost or complexity.
Therefore, there are 3 main reasons VoLTE won't work on a device:
1) Not in a VoLTE area
2) VoLTE not enabled (this could encompass the option simply being disabled per the user)
3) VoLTE being restricted (AT&T restricting access because the device isn't certified, and/or the device not being capable)

So how do you enable on the OP3 with AT&T?

You can't, only thing that would remotely make it work is if your imei was set up as a HDVoice supported phone in AT&T's system (s6, s7, note 5, note 7, iphone, etc). Though that likely won't work either since it'll try to provision the VoLTE and fail and yea.
AT&T does not use "Standard" VoLTE, so even if the phone supports it (like the OP3 does) and they were to allow the IMEI, it still wouldn't work. Phones have to have specific code from AT&T to do their HDVoice (according to their own customer service postings in their forums)
Hello and thanks for any help you can provide.
Problem:
I have Samsung sm-n7505 Germany DBT.
When I go into Settings / More Networks / Mobile Networks.
I have 2 menus to switch my phones Network Modes.
When I try to make a call I get no signal or the call will drop like it is switching modes or the two modes are conflicting and causing this failure.
I use Lebara Phone services sim only I have never switched this out.
I have tried to set both to the exact mode and all kinds of mix match still the same. I also have a problem with the wifi setting the dhcp ip adress at home. I set this to static since I know how to do this and it works fine.
But if I want to jump onto a public wifi, unless I know the exact ip range 192.168.xxx.xx of the public connection, my phone will not connect.
I have the phone rooted with cf autoroot that I downloaded from the newest .mobi site for cfautoroot.
I have the latest available firmware update for Android 5.1.1 .
I have been researching this and find no sign of this in google or here as I can see.
Help is much appreciated!

I can not get 4g network visibled to set in Samsung galaxy note 3 neo,only shows in network " E " after more network setting enabled in which no option is given for 4g Lte /volte
Does anyone know if the Redmi 7 is VoLte compatible on T-Mobile or ATT? I went and checked with the imei on T-mobile's website, and it told me the Redmi 7 is not, and will stop working on the network soon.
Under my T-mobile sim card settings the Use VolTe switch is switched on. Checking it with the “Network Mode Universal” app from the Google Play Store as recommended here:
https://www.xda-developers.com/t-mobile-att-require-volte-phone-calls-shut-down-3g/
shows UMTS as voice network, instead of LTE, meaning it may soon be obsolete. Wish I had known this when I bought it.
I thought I should mention that without rooting or any other hacks besides disabling carrier checking for Volte and VOwifi by entering the usual codes, I am actually getting wifi calling on FreeUP, an AT&T MVNO. Which probably means ATT and all its MVNOs get wifi calling on this model.
So far as I knew until now, ATT blacklists phones that it doesn't sell from using this particular calling feature. ( apart from iphones and Pixels bought directly from Google, because both of those manufacturers refused to let AT&T sell their phones otherwise).
I couldn't do wifi calling on any of my other Xiaomi phones (Mi Max 3, a Mi Max 2 and a Redmi Note 5 Whyred, all rooted), although I could get Volte to work using the shortcode for it. But wifi calling was supposedly blocked from the carrier's end and couldn't be enabled.
I expected to get the usual "no network" message when I tested wifi calling on the Note 9t by turning on airplane mode, then turning on wifi, but it just put the calls through.
(you could always get T-Mobile wifi calling to work on some Xiaomi phones, but TMO sometimes other had incompatibilities).
fyi, the codes, in case anyone reading this is new to Xiaomi:
Code to enable Volte: Dial * # * # 86583 # * # * using the default dialer -- the message has to say volte carrier check disabled for Volte to be enabled.
Code for Wifi calling: *#*#869434#*#* -- the message says says vowifi carrier check disabled for wifi calling to be enabled.
(but check the settings after using the codes because sometimes you still have to toggle them both on)
PS: This model is a pretty decent option for US buyers on a strict budget, as is the Poco M3 Pro.
The next step up if you need North American bands is the Mi 11 lite (about $100 more) and the Poco F3 ($150 more).
