Why does this occur? It switches my data to 3G when I'm in a phone call.

AT&T uses HSPA or 3G for voice calls, LTE migration for voice will come eventually but for now every time you receive a phone call or make one, your phone will switch to 3G and then switch back to LTE when the call is terminated. If you want to multitask while on the phone you will do it at a slower data rate.

This makes sense. I thought it may have been something along these lines. Thanks for the help. I appreciate it.

So everytime I call someone or receive a call,
the 3g on the status bar disappears instantly.
right after I end the call,
I have signal again immediately.
is this suppose to happen to Verizon phones?
I'm confused because I came from at&t. never had such thing on it.
So is Verizon suppose to be like this?
if so is there any mod/tweak that enables me to use data while calling?

Yes, this is supposed to happen. You can't do voice + data over 3g, but you can do voice + data over 4g. There is no "mod" available for that will enable the use of data while in a call on 3g.
Verizon is CDMA, which doesn't offer simultaneous voice/data like GSM does. Unless your phone has SVDO (like the Thunderbolt) it won't do data and talk at the same time over 3G... The VZW GNex doesn't have SVDO.
For the longest time this has been a pain for CDMA carriers (the few that are left) and they're gonna get past it with VoLTE eventually. You'll still see AT&T run ads comparing their iPhone to the VZW iPhone because it can do voice+data at the same time.
If you're on LTE, you can browse LTE data and talk on 3G at the same time, however.
maguro user here. i was talking about this with a work colleague yesterday, and i said data didn't work at the same time as voice, only with gprs/edge. he had me call his cellphone, while on UMTS/3g/H, and data call was still on as i made the call, and let the phone ring a few times.
when i am on a call i cant not see to get data...the data connection turns off by itself and when the call ends data connection will come back on? is it suppose to be like that or is there something wrong with the phone. right now im on software 1.28.708.10. thanks

Happens to me too I believe my frined.
It only happens with mobile data though.
If you are on Wifi, the wifi should NOT disconnect right?
ya if it is on wifi then it is ok. not data connection though
I believe that the phone switches to 2g during calls, and not sure whether this is a telco setting that they do not allow calls through 3g, or a software feature of the phone with the reasoning that 2g signals are generally stronger in most parts of the world compared to 3g.
Just fyi i had the same issue on my "old" Desire HD.

It might be carrier specific. I have no trouble getting (and keeping) HSPA data when I'm in a call.
which version do u have Barry? I am using the international version on rogers. Are you using the at&t version?

Then I believe it to be carrier specific then since the software governing these kinda things should be standard across the board

A UK international version on AT&T.
Ok that is so strange. I have the Hong kong version on rogers network. It never happened to me before and I have used a lot of HTC and unlocked phones before.

ok so i dont think its the carrier cuz i reset the phone and it works sometimes now. if i make a call and browse right away then it will work but if i leave it for too long then it wont work.

guys its because the phone calls you make are on a 2g bandwidth unless its a video call, that's why if you have 2g connection or EDGE active it will get disabled as soon as you make a call.
to clarify, force your network settings to wcdma and then connect to 3g, after that make a call and your 3g will not be disconnected

i tried this and the 3g was displayed in notification bar.. but when i use this as hotspot, i hardly get connected to internet in my laptop (connected to phone) even the 3g was displayed.. this is really bring me down.. as i need to use hotspot while on travel and had conversation at the same time..
is there any other way to solve this?
thanks
Yup got it to work. Thanks.

Hi Marktang... I saw your post from Google as I lost data connection during phone call with my Galaxy S2.
May I know is it after configure the Network Mode inside the setting to use WCDMA only, then the problem will be solved?
Thank you...
Hi! My phone switched to 4g when in calls. I know thats normal. But is there anyway I can turn off that function and keep LTE all the time? Thanks!

In my area 4G is a lower speed connection than LTE.
Check in Settings>Wireless & Networks (More...)>MobileNetworks>Network Mode and select LTE/HSPA+. This will ensure that when you are in an LTE capable zone it will connect to LTE.
If you turn lte to stay on all the time you will not be able to make and receive calls. For now lte doesn't support phone calls, that's why the phone switches to 4g.

This is accurate. LTE only supports data at this time. For voice you need older generations of signal ie. 4G, 3G, Edge

Is anyone experiencing a long delay when dialing out? I am on stock rooted ROM. One of my buddies is having the same issue also. The delay is about 5-10 seconds. I don't have this issue when I use the same SIM card with my old iPhone.
I live in Michigan

I have this with my Note II, and so did my Note I and my Streak.
I have seen this on a few of my friends devices. Test this for me
Make a phone call and watch your data icon. It will go from 4g LTE to 4g then disappear the the call will go through.
Then call your phone and watch as the data icon goes from 4g to nothing then ring.
It seems to b a problem with a few select phones. Not sure if its a software or hardware issue. But I have reported the issue to at&t and samsung . Due to the fact that I have seen it on 4 phones

This is exactly what I have noticed!!!! I am also not sure if it's a software or hardware issue.
Seems normal to me. Voice over LTE is not (yet) enabled/available/supported. For voice, the radio has to switch from LTE to UMTS, and then establish a connection to the new network.

The issue is a total loss of data. So no talk and surf

Just a quick check - is data set to be LTE-only? You generally can't have simultaneous voice and LTE data.
You could try turning off LTE data and forcing WCDMA/GSM data. That might help.
Also, the signal has to be very strong for simultaneous voice and data. When there is low signal strength, the carrier may have elected to suppress data in favour of voice.
You could also experiment with other baseband firmware. That has made a difference on some of my other phones. The configuration of the carrier's towers plays a big role. However, in my limited experience, signal strength has been the key factor.
Good luck!
I have had two phones with the stock builds and base bands next to each other with all the same settings and one works fine the other doesn't.
The weird thing on top of it is that 50% of the time when making outgoing calls it fails. And when people call they receive the message that the line is no longer in service

Stab in the dark: That sounds like a loose antenna connection - if it happens to the same phone all the time (that was the cause of a similar issue on my old Moto Milestone); or a carrier issue - if it happens on the same tower. (Just because two phones are side by side doesn't mean that they are connected to the same tower.)
The code for radio info is *#0011# http://forum.xda-developers.com/showthread.php?t=1802028 (I know we're not talking about fast dormancy - well, we are talking about radio state switching for the OP - but that thread and Erica's two XDA videos on fast dormancy have lots of good info on radios and data.)
I'm all out of ideas now ...
I started noticing a weird thing happening with the phone - the data switches from 4g/LTE to 4G whenever I get a call or an SMS. Very annoying especially when I tether, since it instantly drops my connection speed. It might go back to LTE, it might not, more often not though for some time after I end the call. Is this normal?

HMMM good question. That would be an answer that most likely only T-MO Network support can answer.
Tmobile hasn't implemented Vo lte
