Galaxy S4 missing calls, not receiving calls - Compromised solution - AT&T Samsung Galaxy S 4 General

Symptom: I just upgrade from iphone 4s to Galaxy S4, after about a month use, I missed 4 calls from my friends. The phone did not ring at all, and there was no missed call in the log. This is a very serious problem. someone say she almost broke up with her bf just because of this, :laugh:
Solution:For now I found the solution is to turn off the LTE by go to setting=>Connections=>More networks=>Mobile networks=>Network mode and then choose "GSM/WCDMA". Then you will not miss a call.
Compromise: your data speed is reduced to 4G HSAP+. But if you have 200MB plan and only receive emails like me it does not matter(poor solution for people who has unlimited or 2gb+ data plan), plus by using 4G HSAP+ instead of 4G LTE you get better battary life.
Explaination: I lives in Pullman WA where we have LTE here. Some of my friends using a LTE capable phone (iphone 5, other GS4, nokia 920) also met this problem sometimes (this happens totally random or say I cannot conclude a situation when this will happen). The general idea is that LTE can only handle data transfer but not voicecalls (you can make a call with the LTE on and you will see that your phone swith from LTE to 4G), so if you are using the LTE network and your phone is connected to wifi (at this time your phone is using wifi data not LTE and then you are not connected to the tower at all, this is my guess, I am ME engineer not a communication engineer) and it's on sleep mode (these situations are my assumption) you may miss the phone call. But when you wake up your phone and ask your friends to make test call. you will receive the call.
If you read this post, many people with GS3 has this problem before:

and with iphone 5:
forums.macrumors.com/showthread.php?t=1489651
and their solution is to turn off the LTE through a complicated process(we have such function build in the phone, :laugh,
I put this here to help people who has the same problem, but I also wish ATT can fix this problem ASAP because we are paying for LTE speed. So if you have the same problem with your LTE phone please leave a post here and this could arrise the attention.

Yes, they give me a new sim and my old sim stop working after they activate the new sim. But I put that new sim into the iphone 4s first before I put it into the GS4, Will this cause the problem? Do I need to ask them to issue me a new sim?
Thanks for the reply

Probably not. If you got a new LTE sim then that should not be the problem.

Mobile networks => network modes does not exist on my AT&T GS4.... Just and FYI.

i experienced this before.
this is because LTE network is down in your area, that is why!
it' like you connected to your router wifi at home, you pulled the internet cable. but your phone still connected to the wifi. it just wont let you surf web since there is no internet connection, but your phone still connected to your home wifi router.
know what i trying to say?

i've had this problem with my note 2. i'm now using an HTC one and never had it again..

so you never have your DSL or cable internet down? Samething with LTE network, the lte tower is down. nothing to do with what phone you using!
It takes att about a week to fix it when they received enought complains! that happens in my case, when you call them to report LTE network tower is down, they think you a idiot! Telling or guiding you how to setup your phone! There's nothing wrong with your phone! The lte tower is down!

This is good.

You're a moron. That would be just fine if your phone was left in one spot. But a moving phone that shifts towers......yeah your logic is completely flawed. There is either a problem in the radio firmware or the hardware itself...IN THE PHONE

Ummmm but yeah dumbass we're not talking about a whole network outage.
Everyone would be dropping calls/texts in your scenario but that's not what this is about.
My wife's phone misses calls/texts randomly while moving and connecting to different towers over a 140 mile radius, she has a GS4. Now here's the part that makes your statement dumb. While this is going on, I receive calls/texts perfectly fine on a GS5 sitting right next to her the whole time.
It's a device issue, not a network issue. Something so simple normal monkeys can figure out.

Wow are you just born a total moron or was it a learned response. It's still relevant if it happened on a new phone purchased in February plus there is no definite fix without sacrificing quality. Don't assume you know everything...just makes you look more the ass than you already are.
Just man up and accept your defeat, you lost with your original post I replied to in the first place. Only kids get mad when they are shown how ultimately wrong they are.:laugh:

there is a code for Note3 that let you turn off LTE and stay at 3G. why would you want to stay in 3G instead of LTE ?

[Q] Reception Problems

okay guys so I just switched over from the Galaxy S to the S2, Skyrocket LTE
I had full reception at my house with the Captivate....Now, with the skyrocket I still have full reception....but with a catch
I'll have full service...then all of the sudden it will drop to 1 bar and be unable to send any texts. (Message not sent error). Then, like 45 seconds later it will turn back up to 5 bars and ill get texts.
the time that its off and on seems to be consistently repeating and switching back and forth between 45 second intervals. Also, sometimes ill get all my texts together (9 unread) out of nowhere with time stamps from 5-12 minutes ago.
I'm running STOCK everything:
Android version 2.3.5
Baseband: I727UCKJ2
Kernel version: 2.6.35.11
I wanna root my phone but I wanna make suree there isnt a problem with it.
I think its also important to note that this problem is ONLY in my house and around my house. not anywhere else.
Any ideas on what could be causing this, or any solutions? anyone else have the same problem?
I'd recommend reporting your thread via the upper right link to have this moved, you got it posted in the wrong phone section. I'd try to take a stab at helping ya but honestly it would just be a guess...
Thread moved from AT&T Galaxy S II forums to the Skyrocket Q&A forum...
anyone have any idea?

There have been some problems reported on the LTE network, but the biggest problem was/is.. people not being able to make calls when the network mode was set to lte auto. Depending on where you are, you might want to check the coverage map for your location... and call your carrier.

Thank you, do you have any links regarding the problems reported? I'm in LA, I dont think we have LTE here yet. Also the problems seem to happen only at my house, not even like 1 block down. I know I had full coverage here with no problems on my Captivate. It's just this phone, reception drops to 1 bar, then 5 .... like every 10 seconds, keeps going up and down, I gotta time when to send my texts so they go through lol.
I want to say lte is in testing for la. That could definitely cause issues if they are messing with the towers. The same thing happened to me while we were in Vegas...a few days later everything worked ...including LTE which Vegas previously did not have. Its also worth checking to make sure ATT has u on an LTE plan. Its been documented that if they have not done that it can cause some issues

the captivate is not a 4g or Lte phone...the phone is not trying to switch between 3g to 4g...i think thats the problem with your SII..trying to change from H+ to Lte without succes in an area doesnt have Lte
The only links that I have seen, are for rogers here in Canada.. don't know if that would be of any help to you? While my signal strength is all over the map, I have never had any problems making or receiving calls.

I went ahead and called. It seems the problem is, as everyone suspected, the phone trying to switch from H+ to LTE. the 4G logo seems to change from 4G to 4G (LTE) when it drops reception. Will rooting / roming help stop this? Are there any ways of turning off LTE until they get it fully working?
With regards to the quote above, I currently have Unlimited Data since i got grandfathered in. The guy at the ATT store told me I dont have to change my data plan and I'll keep my unlimited (so i did that). He gave me a new sim which he said "will help give you better reception". Will I still have issues because i dont have the new data plans? I want to keep my unlimited data.
**EDIT**
Just checked on ATTs website and I have "LTE UNL SMT VVMT" data plan.
Thanks in advance for all the feedback guys!
Also, I think its important to note that even if I connect to WiFi, the problem is still there, reception drops and goes up consistently. I've missed countless phone calls and have had to resend a vast amount of texts. I get all my texts together every 4-6 minutes. PLEASE help =/
Did you ever get this resolved. I have the same problem at my house, calls drop frequently and data seems to be not available at times.
Y did u resurrect this thread lol, a new post might have been better. None the less, try the telus KJ3 radio if u don't have LTE in your area, it has really good voice quality, and consistent data rates. If u do have LTE use the new UCLA3 one

[Q] Constant Loss of Signal (Sprint)

Is anyone anyone else constantly losing and regaining signal? I just noticed it once I got home from work. I'm unlocked and rooted. I updated the PRL and profile. I noticed the signal lose after this, but I wasn't paying much attention before I got home.
Anyone have any advise before I RMA this thing?

Yes, I was just about to create a thread asking the same thing. The signal icon turns to an empty triangle randomly for no more than a minute. It's been happening all day =/
The phone is locked and 3G is working. Not sure about LTE just yet.

I think it's because the N5 just has terrible reception in general. I get 1 LTE bar in areas where my Moto X used to get full LTE bars.

I have experienced random signal drops, even when I have full bars. It might only happen when it's switching between LTE/HSPA, but I haven't really payed attention.
Sprint is doing a lot of backend tweaking to support the Nexus 5s. Lots of performance changes hour by hour as they try and set up the network to allow unlocked Nexus phones.
First time allowing a phone on their network that's not sold them so these are all part of the growing pains. Just keep giving Sprint productive feedback so they can iron out the issues.
I went to the online chat and the guy apparently "refreshed the network and fixed the glitch." I thought he was full of ****, but I haven't lost bars yet ^.^
Edit: never mind, he was full of ****...

I have been having the same problem at work and I can trace it to switching between network types. LTE to 3G to 1x. At home I'm good to go. I think it may be because Sprint installed a micro cell in our building and it's not LTE compatible.

Might just be a not so great radio software/firmware at the moment. Most likely future updates will make it better. Now, that doesn't help you in the interim but that's most likely it.
my worst fear.. LG's are notorious for dropping signal. I know this because my old LG Optimus G did it, and many others had this problem as well. You can google or look at my old posts.
I ran a Network Signal Pro log last night and it was a constant signal/no signal. Not sure if it was just voice or voice and date. I have attached it, if someone who knows how to read that better than me could look at it that would be great. I'm running another log right now, will be 60 minutes with a 30 poling rate. I'll post that later. The signal is pretty weak since I am in a hangar at an airport. So we will see how it is.

Why should any "tweaking' be required? GSM networks have let on all phones for years. It would seem that once Sprint allows a phone on the network, it should be in the same position as a GSM network with respect to phones that it did not sell.
Also OP, do you mind providing your general location?
Here is the next log. Never lost a connection.
The only difference I see here is EVDO A at work vs EHRPD at home. Wonder if that is part of the issue?

Ah - other side of the country. Didn't see you had it in your profile as well, my bad.
Other side of the country which makes me nervous that it's not a sprint issue - I'm in Detroit near campus martius and still having similar issues.
it isn't only Sprint, it happens in Rogers and Fido in Canada as well. So I believe it is LG

I feel it may be a sprint issue only due to it constantly losing connection of EHRPD but it being fine now that I on on EVDO A at work. It is the same radio and antenna for EHRPD and EVDO A, right?
I'm going to Salt Lake City this weekend, I'll have to see how it preforms there.

[Q] Tmobile network signal not so good?

So i've had the N5 for 4 days now and i just recently switched to Tmobile from Sprint. When im in my house i rarely have more than 1 bar of service and frequently 0 bars. The phone seems to not automatically switch to any other mode (3g/2g). The attached screen shot is only from 4 hours of use, being outside more than inside and still only little blips of green on the mobile network connection log. I work outside and still being outside 8 hours a day still wont have much green on that log.
I dont have another phone from t-mobile to try out but it seems a few people have said that the N5 has radio issues. Not sure if this problem is phone/hardware related?
My data speeds are not the issue here, its more the cell connection for phone calls. My girlfriend has called me many times with my phone laying on the counter when the phone had 1 or 0 bars and it would never ring or show a missed call.
Ive called tmo and they said the towers are good and i that i dont have a "stong" LTE signal but it is "good". I have also went to tmo store and they swapped out the sim card for me, same issue.
The phone i have seems to be the newest batch of N5's with a 401KP serial number and a 01/13/14 manufacture date.
Im super happy with the phone overall but if not being able to receive calls from people is very frustrating and nullifies all the good that this phone has going for it.
Im in the chicago area. Anyone else having this issue?
Any advice/help is appreciated.
See my attachment. I'm on tmo as well. I usually get between 1-4 bars of LTE, yet, it is always yellow. T-Mobile is known to have issues with penetration in buildings. Here in Atlanta it seemed to have gotten way better as of the past few months to where I always have reception and good download speeds. But, there are still areas where when my phone screen is off it likes to go to no signal, and then to 2 bars when I'm using it. Although, they only happens at my gfs parents house. They all have ATT and had to get a signal booster to get service, while sprint barely gets anything there. So I guess it isn't s big deal at all since other carriers struggle more there.

Try testing HSPA+ (GSM) rather than LTE...you may find it more stable than the LTE/GSM swapover for calls.

So you are postpaid, If you call in t-mobile and ask if you quality for a signal booster as you do not have good service in home but you do outside.
Certain requirements though to get one you need to live in a single family home and not in a apartment complex the reason is because E911 wont locate you and they cannot dispatch police right away
If you are successful like I did you will get one for free and I also got it 1 day overnight express

They still give it out.. under certain environments for example we have 5 lines and 3 are iPhones and 2 are Nexus 5's
all of them are incapable of wifi calling. so they had to just give one to us..
I also kissed ass to them saying that i love t-mobile but i just wished i had service inside.
the rep transferred me to a lady named Donna, i kissed her ass too and got it shipped 1 day overnight express Lol
overall just be kind and kiss ass

1)Remember call in state that you have service near your window but you cannot be at a window every time to make a call
2) ask if you quality for a signal booster and when they say if you have any connected walls or shared walls something inbetween those lines state no
3)They're going to do some troubleshooting if you have edge in or 1bar of 4g or LTE TURN ON Airplane mode they're actually going to ping the device state on the mobile network (testing to see if you're a lier)
Tips: Kiss ass, complement things like i love t-mobile etc, be patient and have a nice happy voice, call using another phone NOT on t-mobile..
i hope this helps! :good:

None of mime are WiFi calling capable. I'll call again, but I've also heard from others that they don't five them out anymore. Is it LTE or HSPA?

It supports EDGE/HSPA and t-mobile newly refarmed 1900pcs HSPA
its pretty future proof as HSPA will be here long. besides HSPA is what makes the calls not LTE
better to have some data and calls than no calls and data at all..
it also conserves battery life as the signal is strong and your device wont have to search for signals

You said to TURN ON airplane mode when i call them?
Sweet talking is the only way you can get free stuff usually.
I see you have a backup tmobile phone... Does it get the same reception in the house as your N5 does?

Yeah,, you have to be valuable to TMO to get this (ala multiple postpaid lines). The last case I saw here was months ago, and he went all the way to retention before they sent him a cel-fi. Regular CSR's may not have the option on their system.
WRT, HSPA+, use phoneinfo app (market) to toggle GSM-only/LTE settings.

Was he a single line or more than 1 line before being sent to customer retention

IIRC (from Nexus 4 forum), he had two lines, was over $120/mo, and had played CSR roulette trying for a cel-fi. After he said he wanted to cancel (he TRULY had poor coverage at home) and got a hold of retention, he was able to eek one out. Most fora say their cel-fi supply has been drained, however, based on user reports.
The main reason I was following this was for a business client of mine. He's 'last mile' internet, despite dead fiber running down his street less than 20 feet away. He currently pays over $400/mo for ISDN 1.5 synchronous 2yr/contract. Yet, I get over 40MBPS at his location on TMO, outdoors, but drop to near nothing inside his metal buildings. I'm unable to convince him TMO is capable of business-critical uptime, but I think a cel-fi in his window could go a long way towards convincing him.

Connection dropping

I keep seeing my 3g connection dropping completely. I'll be browsing the web and im not moving at all and all of a sudden the connection is gone. I first thought it had something to do with the connection optimizer but it doesn't seem like that. Did anyone else experience this or know a solution to that?

i noticed that this was happening when mostly when the phone was going back and forth between 3g and lte. so i changed the mobile network settings to cdma only instead of cdma/lte and it was much steadier.

by changing it to the CDMA setting you are only going to be on the 3g network.

So there is really no solution besides going to 3g only. But it really isnt jumping from lte to 3g . It will show 3g and all of a sudden nothing. Sometimes even showing me the little x over the bars.

This happens in an area with partial Spark.
Mine does same thing because I have 3 towers all equal distance from me. 1 is Spark other 2 are not.
If you travel to another location you probably won't see the issue but in short from talking to some eng. the phone is doing 1 of two things.
A) It see's an LTE signal and as LTE is primary it starts to try to connect to it but before it fully does (thus why you never see LTE icon) it realizes it doesn't support the switched fall back required to allow Spark phones to get calls while on LTE so it kicks you back to 3g. This process continues to repeat :/
B) The phone see's an weak LTE signal, as is primary starts to connect but before it fully does the signal is determined to be to weak and falls back to 3g.
In both cases the phone possibly would never show you the LTE icon as that will only show once fully established and it doing this jumping back and forth causes 3g to go and die where forcing CDMA fixes.
The other downfall to this is it KILLS the battery.
Connecting to WiFi won't help with the battery part either as it still does the jumping around.
Your only option is really force CDMA mode only when in an area like this, for me, this is at home only, or live with it and lower battery life until they upgrade the towers all the way.

Thank you for the detailed explanation. I just got off an hour long phone call with sprint with them trying to explain me my phone is defective and my wifes as well. Then when i told them it isn't they started going into the "Yeah its our network" mode but then came back saying she put a ticket in for me and my wife to get the phones repaired. I told her I don't want that to stop worrying about the phone and to send me an air rave. Problem at my house solved lol. They are sending me an air rave

You could try turning off or on, depending on whether you have it enabled already, connection optimizer

Hate to share the news but that won't solve your problem, it actually could make it worse as it's now another signal to bounce between.
4G IS always priority when enabled, so regardless of you having a "tower" inside your home now, that does not provide 4G, so if the phone's seeing one that does which is what's causing the problem your issue will remain the same meaning you're forced to put the phone in CDMA only mode still.
The problem isn't with the 3G tower or 3G signal, the problem is the 4G signal being detected but not yet compatible with SPARK due to missing the circuit fall back feature, which the phone doesn't know until it attempts to connect. In some areas where it's partially setup the phone can connect to 4G and just calls won't work, in other areas it's disabled or doesn't exist and this problem happens.
Your solution will simply need to be put the phone in CDMA only mode when in a troubled area only, or just leave it in that mode and have no 4g until everything is upgraded better, or deal with as is.

US T-Mobile

So I have bought a HTC u11 plus and should get it today. What I have done the past week is check my bands at the places I visit most. And while driving. I used lte discovery app to help me with this and some Google searches. In my findings band 2 is hardly used when I am at home or driving. My 1+5 is always on band 4 or 12. At home is the only place where it is on band 2 but it switches to 4 and uses this mostly but I use wifi calling at home due to coverage sucking at my house. I did a Google search on band 2 and it is not very good around my areas. So people with TMobile USA should be fine to get this phone and use here. Also my cousin has a HTC 10 from overseas which has less bands enabled and has never had an issue with lte or call connection with TMobile. Once I get the phone I will do more testing for TMobile folks. Let me know your results if you have any.

Lol i got the notification on this and saw CJ. For a minute i was like is he referring to me? Who the heck is CJ lol i laughed after i figured it out. . Anyway so after having the phone in my hands with all of its beauty and awesomeness. I could not take it anymore. This phone works great if you have a wifi and data connection all the time. But for people who still makes voice phone calls it is the worst.. so bad i put it on ebay yesterday. I got so frustrated the other day. I was trying to make a call and when you do, it drops down to 2g,3g. The call qualty on that is horrible. The calls always dropped and when i did have a good connection the quality was horrible. Half the time i would not get text messages and not everyone uses whats app and that is what i was trying to use because i always will have data. No VOLTE which i missed no WIfi calling which does come in handy. So i kept looking and band 2 does more than LTE I believe that band 2 also deals with AWS which is needed for calling. Man i tried.... i tried to put up with it here in the states. The phone itself is just amazing the Pixel that got away is what i call it. So if you are here in the states Dont buy it unless you have data connection and everyone has like data messaging or calling for a strong data connection. I am really sad and dissapointed at HTC the phone i have been waiting for since the HTC sensation 4g. Hopes this helps.

Well, crap. Thank you for conducting the experiment. Yeah, it's the Pixel 2XL WITH an sd card slot, which is what I want, except apparently without Band 2, the thing's hobbled. I was gonna install the Google HDR+ camera app and have it all! Damn.
I got my hopes up because I saw reports of people bringing the Exynos Note 8 over here and getting it to work, but IT has Band 2! Seriously, how tough is it to add these bands! Do people want to sell phones or not?!!
Anyway, thanks again. An answer is an answer, even if it's not the one I was hoping for.
And yeah, if you're reclaiming that term, I completely respect that, but I still gotta go with CJ.
Sucks to hear that. I've been using my HTC U11+ in the Bay Area for about two weeks now and so far it's been absolutely flawless. Not a single issue finding LTE or dropping calls.

I've had the phone since late December and have had the same experience in the greater Baltimore area. Must be different bands/stronger network in our areas.

Sorry for the delayed response, but I got it from Amazon. Took about 4-5 days to receive it even though Amazons system said 2 weeks. I also just noticed that it's a decent amount cheaper now as well compared to when I bought it in December by over $100.

I agree with this I've had zero issues so far since getting this phone. Only had it for a day now but prior to I ran LTE Discover on my HTC U11 and saw I very rarely used Band 2 (San Diego). After some digging I saw how Band 2 works on T-Mobile and I'm OK without it. I'll be in Vegas in a week so I'll be curious how it holds up there, though I don't really expect hiccups. The one thing I do want to get back is VOLTE/VOWIFI.

I'm not far from you and I just picked up my U11+ from Swappa. Does this phone actually read "4G LTE" when in LTE service area? I have not seen it yet. I have the Nexus 6 and a Note 5 and both have had that when in and around Maryland. THanks for replying when you do.

No, it just says 4G. However, when using apps such as Speed Test by Ookla, it says I'm connected to "LTE T-Mobile", and the speed test are roughly what I was getting on my previous iPhone 6S Plus.

Thank you. I did install LTE Discovery and was able to get information on what band I am on and more. It keeps flipping back to 'H' loads which is made me wondering what I might be doing wrong if it is not in the phone itself. I am in a strong 4G LTE area for work (base) and home. My Nexus 6 and my Note 5 always read 4G LTE in an area as such. I still love this phone even though it's not 2 weeks old yet.
I'm tempted to get this for an upgrade from my HTC 10. I don't care too much about the dual camera for the HTC 12+, plus I want it in Red which might not even come out in the US. So with the bigger battery 3,900 mah, about $200 less and the red color now. Would this be a good buy if I typically travel around the east coast?
I have one I purchased on a recent trip overseas to Taiwan. My carrier here in the US is Tmobile and I only have connectivity issues in rural areas. Can someone point me to a stock ROM from Tmobile that would be compatible with this phone?
Thanks.
