Is anyone on AT&T getting this, too? I live, work, and play in areas where I get solid LTE (Chicago). But just today, I was dropping calls every minute or so! I looked and noticed that the symbol says 4G (no LTE). And later on, drop call again. Now it says 4G LTE. And again, drop call, now it says 4G (no LTE).
Does the HSPA+/LTE hand off drop calls? I thought GSM and LTE were suppose to be good about this.

I know this is an old thread but I found this in a search and the answer is, calls aren't made on the LTE network yet. So all calls were on the 4G network, just data goes over the LTE network. There was no handoff, just dropped calls in your case. If you're on the LTE network, and you make a phone call, you can see the phone switch to 4G as by design.
I've noticed, since buying this phone, that it takes a while after hitting the dial button for the call to connect. What could be causing this? This happens even when i'm in an LTE area. Rarely outside of 4G coverage.
LTE is only for data right now, not voice. So when you call, it falls back to the 3G network and takes a bit to switch I guess.
I'm getting EDGE right now and makes instant calls.

I have been wondering this too
I finally got 4G LTE on my block. I am getting great speeds. The only problem is , when I am in a call it reverts back to 4G. Is anyone else experiencing this problem? I am rooted, running Darthstalker S4 V2. I called T Mobile today to put in a ticket. They said it's the first time they hear of this, and it should not be happening. Maybe between us all here in the community we can pinpoint the problem. Curious to hear from you all.
I am pretty sure this is normal behavior. I am not sure why, but that is what my phone has done since day one (the indicator anyway, I haven't tested actual speeds). The HD calling works, so I assume it's still LTE.

I beleive LTE is only for data. Like on the S3 it would show H while on data then 3G when not using data.

I have tested the speed while in call, and they do drop to 4G. The TMo rep told me it wasn't supposed to so that. How can you tell the HD calling is working?

Speeds were good enough for me while on a call I haven't really noticed if there was a decrease. As far as the HD calling is concerned, there is no indicator, but the sound quality is vastly superior (the first time you experience it, you will understand). Both phones need to have hd voice capability and be in LTE coverage. My understanding was that it requires either bandwidth or something else the LTE towers provide. I don't even think it works with wifi calling...

I guess I have a reason to make my wife get a new phone now!! http://forum.xda-developers.com/images/smilies/fingers-crossed.gif
As far as data speeds while on a call they do greatly suffer. Here is a speed test while on a call. If both phones have to be on LTE to experience HD calling doesn't that mean we have to stay on LTE while in a call? As you can see in the screen shot, signal reverts back to 4G. Now I'm back to square one.
Here is your answer: "4G LTE does not carry voice services, so calls will fall back to our HSPA+ network until voice over LTE (VoLTE) software is ready." (Click here for their support page.)
There is nothing wrong with your phone, this is just the way it works currently. I am not sure about the HD voice since that theoretically requires LTE...

I think this pretty much sums it up.
While the industry has seemingly standardized on VoLTE for the future, the demand for voice calls today has led LTE carriers to introduce CSFB as a stopgap measure. When placing or receiving a voice call, LTE handsets will fall back to old 2G or 3G networks for the duration of the call.
I found the info here http://en.wikipedia.org/wiki/LTE_(telecommunication)
I really wanted to like it.
I have been running PA/CM rom since they first came out, flipping back and forth. ZVA came out and i was excited and TOT to it. my signal went to ****.
95% of my day is in a 4g area, on ZV8, I see 4g (and pretty fast speeds) most of my day.
I flashed to ZVA, and i can watch the 4g (at my desk, so basically the same place everyday) flip to 3g for no reason. the worst part is it does it in the middle of something. if i go into airplane mode and back out it goes to 4g, for a few minutes and flips to 3g again. so frustrating.
on the way home we drive by an antenna and with ZV8 i see 40 megabit speeds (i can see the antenna from the car)
on ZVA, it will NEVER flip to 4g. we will come into, and go out of the coverage area for that antenna and it will stay in 3g the whole time. if i flip airplane mode, it will kick into 4g.
absolutely terrible!
so ZVC comes out, I TOT to it for a day. same exact problems. 0 4g like the phone does not even try to look for it! also a co worker has the same phone and the same issues. He requested i flash him back to ZV8 just because of the terrible signal on ZVA/ZVC (he has never run a rom or anything other than stock)
is anyone else experiencing these problems?
is there anything that i can do that might help? id like to rock ZVC, but without reliable 4g its a no go
Have you tried disabling band 26 and 41 to see if you get same 4g as before. If not give it a try. ##DATA# and edit LTE. You will need your MSL. Maybe that would help. You will lose the other bands but maybe that is your problem. Maybe trying to connect to those bands but have bad signal so stays on 3g.
Working well for me surprisingly enough

Had the same exact problems and disabling bands 41 and 26 helped a lot. However, that means you basically are back to non-Spark, but that was still better than the frustrating fall back to 3G and staying on 3G. Some people say that just disabling band 41 helps too.
However, I've noticed much less of a problem recently with this issue with all 3 bands enabled on ZVA. I suspect that Sprint is upgrading towers around my area to better address this issue. So maybe it's not a software issue on our phones.

The problem is ecsfb (enhanced circuit switched fallback) spark phones can't connect to the voice network and lte at the same time because they only have one antenna instead of two. But to be able to switch back and forth between lte and 3g the towers you're on need to have ecsfb enabled. I had the same problems before but it seems in my area (nyc) that they're starting to enable it as I'll be on lte get a call and then get put back on lte right after the call is up. The coverage for lte in my house is pretty horrible though the signal is like -120dbm outside its much better like -90ish. I just got an airave for my house because I was getting some dropped calls and it worked great for like the first hour the signal went to like -47dbm for the voice/3g network. However after a while it stopped using the airave and it went back to using lte and regular voice towers. I switched my phone to cdma only and it started using the airave again but just now I switched it back to lte/cdma and its no longer using the airave. So that kind of sucks lol. But back to spark it seems to be improving regarding switching to 3g/lte but the coverage hasnt changed much atleast in my house. Whenever I check which band I'm on its either 25 or 41 I have yet to see it go on 26. Hopefully they can hurry it up I considered switching to tmobile last week after sprint tried to charge to say my next bill would be $240 after they told me two weeks before it would be $180 smh. I complained like crazy and they decided to pay the difference and lower my bill so I'll stick with them for now.

Yeah, another known issue with triband phones... The Airave won't connect if your phone is in LTE. But because your phone gets crappy signal at your house, you'll get crappy LTE that intermittently connects, so therefore airave only intermittently connects when you are on CDMA.
I have Tasker automating the switching between LTE/CDMA and CDMA only when I enter and leave my house, but I this solution isn't the best.

I downloaded tasker and I can't seem to figure out how to automate it to turn on 3g when I'm home and 4g when I leave would you mind letting me know how you set yours up?

4G uses a lot of battery, I stick to 3G which is fast enough for me plus LTE is not compatible with my Airave 2.5+. Also why not use WiFi at home it does wonders for battery life?

3g is way too slow for me I get 1mbps on average up and down. 4g may take more battery but for me it lasts long enough and the benefits are much greater. I do use wifi at home though but if you have the network set to lte the phone won't fully connect to the airave atleast for me because
the lte signal in my house is very low (about -120dbm). So in order to take advantage of the airave I have to set it to 3g even though I'm using wifi. The only alternative I have thus far is the anycut app I put a network settings widget on one of my home screens I can click that and it brings me to the lte/3g setting but its still not as good as having the phone switch itself instantly.
Yep, Airave doesnt support LTE, but do turn off data at home as its an unnecessary drain, dont know about your internet but my Comcast 30Mbps is faster than using the network, plus Airave uses 3G by drawing fom main internet anyway. Also restrict your Airave in settings to only your family numbers unless you want unnecessary connections from neighbors causing bandwidth loss. If you have a big home, call and Airave support will increase your Airave power output to cover about 5,000 Sqft.
Sorry, but theres no reason the phone should not be switching dynamically to 4g as the signal comes available. When I'm at work, and on 4.4.2 it will stay on 4g, and flip itself to 3g in the middle of a file transfer!!
on ZV8, it will get 3 bars of 4g in the same spot.

Airave does not support LTE, so if you dont set it to CDMA only it wont connect to Airave. Thats why even Sprint support says to set to CDMA only, when near an Airave.

data connected on voice channel is 2g, not 3g
there are 3 channels: 1xRTT, EVDO, and LTE

What I'm more referring to is the settings in mobile networks. You have to put it to 3g/cdma depending on your rom and whatnot to be able to connect to the airave.
Band 26 isn't out yet if i'm not mistaken. I believe 41 is limited also. Disabling 26/41 will bring you back to nonspark band 25
i dont know how airave got involved in this thread. i could care less if i get solid 3g at my house, i am more concerned about the spark rom's delivering a reliable 4g connection when its available (which it does not)

It's not a great of a solution, but it is automated. I have a profile with the state being connection to my home wifi. Enter task turns off keyguard, then enters mobile data settings, turns on the screen, and then uses two touchscreen taps to tap mobile networks then CDMA.
To execute screen taps, you use a Run shell command of "input tap x y" where the x and y are coordinates of where you want to tap. You figure out the coordinates by showing touch data in the developer options in settings. Be sure you enable root access for the run shell command otherwise it won't work.
Then you can shut the screen off with a system lock. The exit task is just opposite.

Yikes thats a bit of a setup I'm using anycut with a network settings shortcut on my home screen it goes straight to the setting page for switching to lte/cdma.

Well, Tasker can enter the same page that switches lte/cdma via the Mobile Data settings. The issue is there is no Tasker setting or plugin or anything I've seen that lets you actually change the setting without simulating button taps via a run shell command.
Like I said, not a great solution, but it works. When I enter my house, I'm on CDMA, and when I leave, Global setting without me doing anything.
Anyone else on the ATT G4 having problems with LTE connectivity? In areas where I'd usually get 5 bars of LTE service, a majority of the time I get 2 or 3 bars of Edge service. Putting it into airplane mode and back out doesn't help, turning mobile data on and off doesn't help, and neither does removing the SIM card (and reseting the phone in the process). It seems to come and go whenever it wants to.

All I can guess is, it's probably just the ATT network itself. They did some upgrades around here a while once Cspire started hyping their fiber optic network and I noticed on my older phone that in areas where I used to get 3G I was stuck getting edge. Even with my G4 I can park in perfect view of a known ATT tower and it'll hit 4G and within a minute be down to 3G - same with strength. Get 5 bars, don't move, no data, no call, and it'll drop down to no bars but still connected and bounce around, usually settling at 2 or 3. Even though ATT says they have full LTE out here I rarely actually see the LTE logo display in the status bar.
I've been using OpenSignal to try to map out coverage areas though, been pretty handy in finding towers and chasing stronger signal

I m using lg g4 h810 AT&T it was working well one day i put a memory card in it signal disappear never came go to software and hardware experts but nobody has solved my problem all other functions of cell phone working properly
