Modem issue or something wrong with my phone? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Have had the AT&T Galaxy S4 for a few days now and I have noticed that in my area if I go from a 4G area to a 4G LTE area the phone doesn't seem to prefer to connect to the LTE band.
Perfect example being I can sit next to a friend who has a Lumia 920 and he has LTE signal. On my S4, it shows plain 4G.
If I put the phone into Airplane mode and then take it back out, it will show the 4G LTE.
It seems to also do this if I go from a Wireless network the phone will prefer 4G over 4G LTE.
Any thoughts on this?

I noticed this also. It takes a significant amount of time for my phone to switch to LTE. I used to have great LTE signal at my university with S3, but now with S4 I only get 2 bars of regular HSPA 4G.

No problems here but I'm on rogers in Canada

Anyone missing LTE

For those that had LTE prior to jumping ship to the Nexus 4 are you missing it? I mean I currently have the Iphone 5 through AT&T with LTE coverage and I must say it does feel nice be quickly stream video instantly life for example Youtube videos don't buffer at all for me. I think that is the only negative thing for me in regards to switching over but I would like to hear from anyone else as to if its LTE really a game changer or have or have' got used to live with out LTE anymore.

Well from what I have heard LTE works with Nexus 4 on AT&T but someone can correct me on that as I'm up here in Canada. I have noticed a big diff in streaming and what not but my speeds on 3G were manageable compared to what I hear ATT 3G is like?
Plus those with their Nexus 4 on T-Mobile's HSPA+42 are getting close, or even higher than LTE speeds so they're not entirely unsatisfied. I personally don't have LTE, but those are just my 2ยข

Not a game changer... I don't have to wait for videos to buffer. Hell, I downloaded 200MB's of data in mere minuets..

What I have read so far that LTE is only available if you live in an area that has AWS band 4 for AT&T which in my case I don't live in such area so no the nexus 4 might have an LTE chip but is half baked so this is why I posed the question as to those who would be leaving LTE behind for the nexus 4 are you satisfied with drop in data speed?
Phoenix, Raleigh, San Juan, Los Angeles, Las Vegas, Oklahoma City, Dallas, Chicago, Charlotte. Also Athens, GA and College Station, TX.
This doesn't mean that AT&T's Band 4 LTE network is actually live in these markets.
LTE tariffs in the UK are a joke. Loads of money for tiny data caps. I am on unlimited data 3g and I regularly top 20mb down. Happy as Larry.

As I'm on wifi 99% of the time I rarely use LTE on my Rezound. Only thing I did notice is that when Verzion updated the towers in my area for LTE I finally got decent reception in my house.
I had a Thunderbolt when Verizon's LTE network went live so I was one of the few that got to experience the 50mbps speeds before the network was as big/full as it is now.. And really T-Mobile HSPA+42 in Chicago isn't the worst thing in the world. Hell I was getting by on AT&T GoPhone speeds for a while.. It really isn't a huge deal. Also AT&T band 4 LTE is only confirmed live in like, Oklahoma.

[Q] 4g less then 3g

Just bought a new Galaxy 4 and i'm only getting 3g in my house. As of yesterday with my 3D HTC, I was still getting 4g.......anyone know the answer to why i'm getting worse signals??
The evo 3D only did the slow old 4G called wimax the new S4 uses LTE a new type of 4G that is 5 to 10 times faster than the old 4G it is slowly rolling out so be patient you can only use the new 4G on the S4.

I knew the guy selling me the phone would lie about the service. He told me regardless of the LTE in Tampa I would still be able to use 4g wimax.

Ha.. not the first salesman to lie, probably won't be the last.
I am in Tampa as well and when the phone is in cdma /lte mode, I get the 4g icon quite often. The problem is that date is very slow or non existent while on 4g. So I keep it on cdma only now.

Thanks for the reply from someone in Tampa....do you know when we are getting full LTE coverage? the salesman told me I could at least still get the 4g winmax coverage. Also, I head the phone doesn't have the icon for LTE so there is not way of knowing if we are in LTE....is that correct?
I have the galaxy s4, so I do not connect to the old wimax 4g. When my phone is showing a 4g connection, its LTE. However, Like i said, it's not fully implemented, at least that is my guess. Because date speeds are VERY slow or nonexistent even when show full bars with a 4g icon. I have seen the 4g icon in many places around tampa, but, 3g is faster so I leave the LTE mode off. As for when LTE is scheduled to be fully on, I don't know. I've been getting the same answer for a long time. "by the end of the year", is what they told me most of last year.
The GS4 does not have a wimax radio, so you can not pick up a wimax signal, only LTE. If it displays 4g, then you are getting an LTE signal.
You can use sensorly app on your phone to get a map of LTE in your area thats done by users.
Here is information regarding Tampa LTE:

Not getting 4g?

I noticed the other day that for some reason I am not getting 4G on this phone other than after a reboot.The moment I connect to wifi or go from a 4g to 3g area, it never goes back to 4g. Is there something I can do to fix this? My galaxy nexus and s4 all have 4g during these times as well.

[Q] 4G vs hsdpa in status bar

I have just tried a 4g Sim in my note 3 the status bar shows an h which is what it has always showed. It never showed 3g just h.
If I am connected to 4g what should that bar show an l for late or 4g?
I am in the UK and currently with three but testing ee's 4g service.
Thanks

You get a HSDPA+ signal if you're not in a 4G area, I am in the same boat, I am also with Three (waiting for their 4G service to come out before deciding weather to switch).

Cool but on 4G what should the status bar say?
On 3G it shows H rather than 3G so I don't know what it will show when correctly connected to 4G.
Thanks
It will show 4g.. see attached..

Three are piggybacking on EE's network for LTE, I am with them also, and EE have the fastest bands currently. So I expect the LTE to be spot on. Currently their signal strength has gotten really poor, I am hoping it's because they are swapping the bands to jump on EE.

Where did you hear that? As far as I'm aware, Three are building their own LTE network, though some of it will be spectrum acquired from EE.
Three did share it's 3g network with TMo/EE, but I've not heard that this is the case for 4g.

I first read it on a Three web forum, I was quizzing them about how the signal strength had suddenly gotten super poor. Can't remember which site it was I scoured so many as it was and still is annoying that signal barely goes over 2 bars even in a big city (Leeds)
As for the spectrum, they purchased some from EE but are running on their network bands (only intial start up maybe?) - EE 4G goes live here (York) this month and Three goes live January. So close together would assume that the starting of it would be on EE's spectrums until further?

The spectrum they bought from EE was in the 1800MHz band - the very same band than EE's LTE sits in.
So no. I don't think they will be using EE's network at all.

Three are not piggybacking on EE's network, they merely acquired some of the 1800Mhz spectrum from EE (That EE was forced to sell by OFCOM to get the go-ahead for their early 4G Rollout), supposedly Three got it for free as well. Three also acquired some 800Mhz spectrum during the auction, so they have both.
As far as I understand, Three aren't allowed to use all of the 1800Mhz spectrum they acquired until September 2015, but they can use 2x10Mhz of it now. I don't know which of the two blocks they're using for their current rollout, or if they're using both.
Never mind all of that, you should see 4G in the status bar if you're on 4G. Make sure you go into the settings and set the Note to connect to LTE/WCDMA/GSM services - my Three Note 3 didn't originally have that option and when it recently appeared, it was still on WCDMA/GSM.

[Q] [VZW] VS98012B LTE Connectivity Problem?

Updated my phone (VZW LG G2) to the latest software patch that went out recently (Dec 20/21?) and now my phone will default to 3G service more often than 4G LTE. My home gets very strong LTE service and I could speedtest up to 20mbps at times on it. After I updated, however, my phone will connect to 3G about 90% of the time. Rarely does it connect to LTE. This isn't just at my home, so I don't think it's a local tower issue as I've had the same problem in town as well.
Has anyone else encountered a problem with LTE connectivity after updating to VS98012B?
edit: If I switch on airplane mode and then turn it off, sometimes it will switch back to LTE.
Flashed modem only here, no problems.
If you are still on pure stock, call Verizon and let them address it for you.
I've been searching for this problem as well. My wife's HTC One is sitting beside my G2 Rick solid on LTE, and mine is stuck on 3g. This only seems to happen in the house, so maybe hers just gets a better signal than the G2. On the rare occasion I do get lte, my speed tests are always much slower than hers. I know it's not an lte problem because out in town with a stronger signal I can get about 40 Mb d/l

Yup, I have the same issue after upgrading to vs98012B. Mine is rooted by the way.

I'm not seeing this problem. In fact, it's the opposite for me. I'm rooted and didn't want to go through the hassle of losing my custom recovery, so I waited until a stock, rooted version of 12B released. I flashed it as well as the corresponding 12B modem zip. I live in a fringe LTE area and it was not uncommon for me to see 3G in my house. Since the upgrade I've only been seeing LTE. I'm very happy with this update.
I've noticed today seems like I'm stuck on 3g
