So I got my Z2 and am loving it so far. No problems that really take away the experience of using this amazing phone. However, does anybody else notice that the phone switches from LTE 4G to H+ during a phone call? The switch happens instantaneously and it's hardly noticeable unless you're looking at the screen. Whenever I am on a call, my phone switches to H+ rather than staying on 4G. I only noticed because I tether my laptop and the speed on my laptop suddenly dropped during calls.
Because you cannot normally make a call on any LTE network. LTE is currently for data only. There any only few operators in the world that offer Voice Over LTE (making phone call on LTE network).

Ah I see, thanks for clearing it up! I've never noticed this on my LTE-enabled Nexus 4 so I thought this might have been specific to the Xperia Z2 only. Thanks for the clarification
I have a TMO Nexus 6 and it does the same exact thing. But in my case, I was told to switch off VoLTE because whatever my carrier is doing with their towers is messing everything up. So now I'm stuck with getting random/jumbled texts all the time. Oh, and sometimes my phone doesn't ring so ppl think I'm ignoring them - hella sketch, but what're you gonna do.. We both have great peices of fine hardware in our hands, let's just be thankful we can play angry birds in ultra fiiiine HD ??

I've been having this problem probably once a day since I've gotten the phone where my phone will lose data signal while switching between 3G and LTE and the only way to get data back is to restart the phone. Turning airplane mode on and off won't work either.
Ive had that issue too..but most of the time it switches back n forth no problem

I haven't noticed any data problems until today. I am unable to connect to 3G. We do not have 4G in my area.
These problems are probably bugs in the LTE System.

why should bugs in the LTE system affect 3G?
the 3G our phones use is not exactly the same as standard 3G unless you force your phone into EVDO 3G via the ##778 menu. which if you are not in a 4g zone I would recommend simply for stability. The 3G our phones use is basically a layer between 3G and LTE as I've had it explained to me.. I really don't know much else about it though, sorry. I'm sure someone else here can shine more light on it however.

Same problem with it dropping data signal and never coming back without restart. At least now i know its not a hardware issue

Sent from my HTC Rezound
same here guys. call Verizon and let them know. I think it helps if a bunch of us make them aware.
I've had a ton of weird data issues with the Rezound. I get 1x where i should get 3g, i get 3g where i should get 4g and i get nothing way too often.
I've only had this happen once with the rezound. Shows nothing but bars, no data can be used. Sometimes switching to 3g or 4g in lte on/off helps.
Had this problem intermittently on both my wife's and my bolts, completely agree its just a lte being a new tech issue.
I've listened to a podcast on how the handoff works and its definitely not fool proof.

phone will reboot and you should get 3G back
This changes your network from eHRPD back to EVDO Rev.A. For LTE phone owners, eHRPD causes 3G to die (most of the time anyway) when the LTE network has problems. Get back on normal EVDO and you're good to go.
^ from Jntdroid on another forum (not sure if we're allowed to post to other forums here) I'm not positive on where he got it from, but this is a capability of all HTC 4G phones
I've had occasional issues with being down to 1X, but even that was only during nationwide 4G network issues, definitely get in touch with VZW about that... not that they have enough sense to fix anything *sigh*
Data Connection slow to Acquire (3G/LTE)
If I'm on the subway, or somewhere with no service, then come above ground, I get voice (full bars) but no data -- it could take upwards of 3 minutes+ for data to come back up. Any thoughts?
I've been losing my 3G service throughout my city, being restricted to 1x so many times lately where I SHOULD be getting 3G!(4G isnt available in my area yet). It's really annoying...perhaps nexus isnt theeee only one...

Same issue as you. I live in a 3G area only and my 3G drops out a lot. Even a reboot doesn't get it back. Not sure what to do :/
AT&T is secretly throttling all of its smartphone customers during phone calls. This was tested on several devices including the Galaxy Note.

I noticed this the other day as well. I don't use data very often whole on a call, and when i noticed the slower speeds, I attributed it to where i was.

Yeah it's really noticeable when you do something try to send a picture message while on the phone. The upload speed is just crazy low.
No throtling being done here. From my understanding during a phone call lte simply cannot be used in conjunction with voice calling, so the LTE radio is turned off and voice is sent over hspa+(or whatever other bands its using) and data switches to HSPA+. So not neccesarily intentional throttling per say, just hardware and technological limitations. Once VoLTE is more common practice I'm sure this will change.

That's not really true. If it were then the faster the connection you have, the faster your on call connection would be. If what you were saying was true then when I'm in an area that gets 9 megs during a call, I should get better on-call data speeds than if I was in an area with 2 megs. Instead regardless of if I'm in a 9 meg or 2 meg area, my data speeds during a call still instantly drop down to around 1 meg and the upload ALWAYS goes down to the 20k area (even if I'm in an area that gives me over 2 megs of upload. BTW, it wasn't always like this either. It isn't a limitation of technology, it's a limitation placed by AT&T, most likely to save spectrum. The crazy thing to me is they air these talk and surf commercials but you can barely do it now. If you compare it to Tmobile, it's like night and day.
I saw that the other day when I was on a call. Thought I was just in a bad area. Just tested on my coworkers note while he's on a call, same thing. Lame.

How is it a hardware and technology limitation if the SAME PHONES perform DIFFERENTLY on different networks using the same technology?
Ok some of you guys really need to research more about how AT&T's 4G lte network works lol,Lte is purely for data so when not on a call the phone will sit on the lte band but the moment you make or receive a call the network hands off the phone to a hspa, hspa+ or edge (connection if the other 2 3g connections hspa or hspa+ is not available) . Once the call is done the phone should switch back to the preferred lte connection. Currently not being able to make voice calls over lte is a limitation by the tech, once voice over ip is ready to be implemented on lte then we're good to go.
Sent from my SAMSUNG-SGH-I727 using xda premium
I can confirm this on my Note. I thought it was just an odd quirk for me but I'm partially glad to hear it affects everyone. On my old HSPA phone I could maintain 2-3 Gbps at home even while on a call - useful for work so I could be on a conference call while also remoting to my work computer's desktop. Now when I'm on a voice call the data connection becomes nearly useless. I may have to switch back to my old phone next time I need to do this - which is ridiculous!
So even if a phone call does force you onto HSPA, they are still throttling you far below the available bandwidth.

This issue has nothing to do with LTE though. I know I saw someone earlier in the thread bring it up, but that has no bearing on what we're experiencing.
I noticed the same thing as well last week when I would make calls. LTE shuts off, 4G kicks in for calls. Hang up, LTE turns back on. Just like Verizon's no data while talking its simply a hardware limitation on the network for now.

From what I've experienced it goes beyond just kicking you down to the HSPA network.
They definitely changed this. Tested this extensively when the skyrocket came out
The hardware is not capable of both seperate radios operating at the same time and voice over lte has not been implemented.
Plain and simple.
When you make a call the lte radio goes idle. The hspa (3g and hspa+) radio activates
Speeds during call should be the equivelant of speeds achieved with a 3g phone...like we confirmed with a gs2 Back then
Now though
Slow speeds while on a call
tested 3g speeds...added the phone apn and select it. It may or may not work but if it works it will lock you onto 3g briefly enough to do a speed test. Compare that to your in call tests. or use a 3g only phone To get a comparison test IN REAL TIME
Technically att could begin throttling but it could be network issues as well.

Scratch everything i said...they have obviously changed this since those tests we did. In call Speeds come in at 600 kbps and no upload at all and out of call 3+ mbps
Althouh slow...600 mbps should load pages etc...but it isnt.
Definitely something screwy going on. ..time to call att again

So...if you have slow speeds while on a call either the 3g network is having issues or the 3g speeds suck there. You absolutely will not achieve lte speeds in a call.
If you want to test 3g speeds...add the phone apn and select it. It may or may not work but if it works it will lock you onto 3g briefly enough to do a speed test. Compare that to your in call tests. or use a 3g only phone To get a comparison test IN REAL TIME...dont go off of crap you were doing with a phone 3 weeks ago. We all know the att network is not that consistant.
Technically att could begin throttling based on the pta apn. ..but so far our testing shows exactly what I described above

That's what I was talking about. I could live with a fallback to HSPA until they implement voice on LTE, but the results are much slower than that.

Perhaps YOU should do a little more research...I assure you I am not a ROOKIE when it comes to these things. I have known for a fact that people were able to surf and talk on AT&T's network in the past without any problems. Now internet is practically UNUSABLE while on a call. Pages wont even load. There is something very underhanded going on.
Even by your own statement the phone should revert to 3g speeds while a call is being placed so why are speeds equivalent to EDGE/Dial Up when people have adequate signal strenght?
Using CM9 Unofficial,
when I'm making a call, as soon as the call goes out my 4g indicator drops down to HSPA, and then 3g. During the call, the indicator switches frantically between H and 3g...and after the call, it takes several minutes to go back up to LTE.
Is this normal? Maybe i just never paid attention to the signal indicator shortly before and after a call...or maybe the stock ROMs just don't show the drop and then the pickup of the 4g LTE signal.
I'm aware that there's no VoLTE yet, but i also didn't know that the phone completely dropped--and then had to reinitiate the LTE signal just because of a phone call.
Data works while the call is in-session.

Yeah even on the stock firmware whenever you start a phone call LTE is dropped. I remember this because I have bad 3g coverage in my area but LTE is great (I know Backwards) but whenever i get on the phone I have 2-3 Bars but browsing the internet while off the phone on LTE I easily get 5 bars. You must have missed it because on the stock it goes from 4G lte to just 4G.
AT&T doesn't have Voice over LTE yet. Perhaps the indicator is showing you the information that would be most important while you are making a call (3G/HSPA+ reception).
This is only a guess of course.

This is sort of my point...and the issue, =(. Mah brain says that there shouldn't be an issue keeping up a LTE connection because it's not being used for voice. I could sorta understand if the phone wanted to prioritize the use of LTE if it wanted it for voice. But why should it drop it during a call.

My understanding is that the icon is the type of connection that the phone has with the nearest cell tower. Therefore since there isn't any VOLTE (Voice Over LTE) it needs to drop the LTE connection and connect with the same cell tower but without LTE (or nearby cell tower if LTE and HSPA+ use different ones) in order to make a phone call so it will lose LTE while the call is in progress. I'm thinking this is because the phone will only use one connection at a time so it would have to stop using LTE in order to use 3G or HSPA+ or whatever.

Yup. Correct. During a phone call, your phone will be on 3G/H+, LTE will be dropped. Its the Network, NOT the phone.

Hi all,
This question might have been posted already seeing as this phone is about a year old already. I'm running the STOCK ICS ROM OTA 4.0.4 unrooted. I've noticed that after the update my phone keeps switching from 4G to 3G and back but the problem is so bad that I lose every bar of signal (i.e. empty bars and of course no data) for at least a minute when the phone switches. I've already gone through the process of getting a replacement phone and I will need another because the receiver (speaker inside when I make a phone call, not sure what its really called) sounds awfully tinny and when the hang up tone plays the speaker sounds like its about to blow out. I lowered the in call volume to half, but it still doesn't work and my phone sounds tinny when ever someone talks during a phone call. I never had that problem with my old RAZR. As for the data issue, I am aware that I live in an old building because at the most I get between 3-4 bars of 4G LTE but sometimes as low as 2 bars. However, outside on the street I get full bars of 4G LTE and it still switches back to 3G on it's own. I have tried Motorola's restore connectivity app on the play store but that didn't work and I don't have anything like smart actions or LTE on/off app running on my phone.
Is anybody else having these issues? At first I thought Verizon sucks in my house but it doesn't I still get crystal clear sound on calls and text messages are promptly sent and received. I also, of course, live in a 4G LTE area with good solid coverage. As a control I have an iPad 4G LTE with Verizon on a separate account and it consistently stays connected to LTE. It never drops below 2 bars and the LTE of course maintains its fast speed. On the other hand, the RAZR, will switch between both technologies at least 5 times a day if not more. I know that they both have different radio technologies but they should at least be similar in some respect. I have also seen an iPhone 5 at the Verizon Corportate kiosk at my local mall. It's obvious there are repeaters but they are not for 4G because none of the phones are on 4G, they are on 3G. The iPhone 5, however, had one bar of LTE and it loaded up a web page just fine and I never saw it drop back down to 3G. I'm trying to see if there is a solution. Have any of the Jellybean ROMs addressed this issue?
Is anyone else whos on sprint/TMobile having issues where the phone cant decide wether to connect to a sprint or TMobile tower? When im at my home i have a very weak TMobile 600mhz signal and a strong sprint band 41 signal due to the magic box. I also can pick up the band 25 signal the box uses and my phone refuses to just use the stronger faster sprint signal. It absolutely insists on using the TMobile signal. Is anyone having similar issues? Even on wifi its causing network interruptions so i have to reload a page several times to make it use the wifi.

I have no idea of this is related but.. I'm on T-Mobile, with T-Mobile home internet as well, and for the last several days my phone is having issues connecting and the home WiFi is doing the same thing. I'm in a rural area so my signal is weak, but it's been fluctuating WILDLY since the merger and sometimes it does seem like my phone is struggling trying to decide what to connect to. There's definitely something going on with the network at least in my area for the last 2 weeks for sure

Sounds like this will be happening until the transition is done/5G is more widespread. These are TMobile models. When mine was first turned on at the store it had the T-Mobile splash screen. The ability to access sprint towers was added via software update post merger. I figure once the 600mhz band is fully rolled out the issue will go away as a result of the signal being strong enough.
