[Q] Signals Problems after 4.3 Official Update - Galaxy S 4 Q&A, Help & Troubleshooting

Hello all!
I'm from Argentina. (Excuse my poor english)
I have a full stock S4 i9500, bought to Samsung (without any carrier logo, unlocked).
During christmans night i received a notification about a new update available, i just downloaded it and installed it. Phone is now on 4.3 (Knox and other stuff are now available).
Since that update, the mobile signal is working very bad.
Every 2 or 3 hours signals completly goes off.
If i restart the phone, or turn on/off airplane mode, signals come back.
If i just leave it, takes more than 1 hour to recover signal.
This is becoming very annoying, since i uses sms a lot with my girlfriend (she don't like smartphones) and also, im loosing a lot of calls during signals fails (when signal come back, i ussually receive a lost call message).
I searched forums for this same problem, but i just found people who had stock problems, and in my case, problem become with the new update.
I want to avoid full factory reset if it possible.
I can post any screenshot if needed!

Hero bugged since the first day

Hello All.
I open this topic because I can't find another one about the same problem...
I loose the signal many time per day (sometimes 1 or 2 times per hour)
With the latest official ROM : I loose signal and I must enter pincode to reactivate phone.
With ALL other ROM (from 1.5 to 2.1... I tried a lot of them....)
I still loose signal, but, without having to pass trough the pincode screen to reactivate the phone.
- sometimes It found signal alone
- sometimes I must enter/exit airplane mode to find back the signal
- sometimes I try to enter airplane mode but the phone never stop loading airplane mode and I have to reboot the phone.
This bug appears when I'm in an area with a low signal, or after sending 5-6 sms or making 1-2 calls in a short time.
I'm with the latest Radio JU. (I re-flashed It many times)
I have this bug, since I bought the phone. And I'm waiting for the famous "update" since October...
With every New ROM I hope It will work and It makes me waiting for the official. But none of them really worked...
Am I alone in this case ? I never heard something like that (I heard about the low strenght of the signal reception, but not a bug like me)
Must I bring back the phone to the shop ? Or the next update will do something ?
It really does sound like there's something physical wrong with your phone. I have never had any problems like this, and i havent heard of anyone else that had that same problem.
I'd take the phone back under warrenty (remember to flash original ROM so you lose root access if your phone is rooted) and get it fixed or swapped for a new one...
hmm really does sound like a problem specific to your phone.
to be honest I've never had this problem.. and I would suggest that your inability to find anyone else with this "bug" would mean nobody else has either.

Thanks for you answer, you confirm what I suppose : hardware problem.
I'll wait for the official update, I'll try a rooted version .
If there is still the problem I flash the official one.
And after that if it is'nt better , I'll bring it back to the shop (It's under warranty until September).

Phone hangs sporadic after calls (2.2 only)

Hey dear devs,
so ive got a little problem. Im a flashjunkie and tried all the different firmwares. All eclair firmwares JM1/3/5/8/9 went fine for me and i had no problems, but since the first froyo (JPC) ive tested, ive got a little problem with froyo.
First some things about me and my phone. I live in germany, my provider is o2, and i also bought a brandet o2-phone. The first day i got it, i flashed to JM5 and unbrandet it, but now to my problem:
My phone hangs somtimes and very sporadic (1-2 times a week) normally after longer calls >10 minutes.
But let me explain a little deeper. It first appears with JPC (my first froyo).
Im doing a longer call and when i finish i take the phone of my ear and have a look an the display to end the call. But i cant click the hangup button. The green listener symbol in the upper left corner is there and blinking. The only thing i can do is to press the menu-button to get back to my homescreen. All is working fine then, but i cant do or recieve any calls because the upper-left green listener symbol is still there and blinking.
When i try to go to flightmode the phone normally hangs completely, only a reboot is fixing the problem. I also had the prob one time within a call. I was on the phone and suddenly my partner was gone.. i didnt hear anything and he also didnt hear anything. Same symptoms: green listener symbol blinking, and when trying to switch to flight mode, the phone crashes. Only reboot is working.
This problem appears in ALL froyo firmwares i tested (JPC, JPK, JPM, JPO), and yes a wiped, i cleared all caches, i reflashed all the firmwares, flashed with kies, flashed with odin (with and without repartition). So i did all the stuff we all used to do to get this problem fixed...
I first thought it was a failure of the beta-firwares, but also the JPO has the problem. There is one thing that might have to do with it... I live a little bit outside of the town and in my house i have a low signal. The problem appears in 9 of 10 cases in the house until now. That might be bad luck, because its very sporadic, and normally i do longer calls only when im at home... But it may also be part of the problem, perhaps because my phone wants to change the to another umts-provider, that has a better signal?
I also thougt that it may be a sim-problem, because my sim is about 5 years old. But i ordered a brandnew sim from o2 and yesterday i had the failure again. It only appears after or right in the call.
Has anyone experienced same problems? Or can help me find out what problem i have?
Thx for all answers
Cheers, Donald!
hi!
yes, i can second that! i have exactly the same problem with my o2-germany-provided SGS, even though I unbranded it by applying the scandinavian froyo-beta via registry hack. So far I did not find any solution. Sometimes this even happens during rahter short calls of 10-15 min. Too bad
Yes i can confirm the Problem. I'm with O2 Germany too. First I thought it is a Problem with both party's hanging up the same time. But I couldn't reproduce the problem at will...
So, the only thing, we can do at the moment is to wait for official o2 brandet firmware. Does anyone know when it will be released?
Greetz DN
Until now i haven't heard about a release date...
also on jf3!!!
i've got the same problem! but i had this bug already on stock eclair jf3!
so i updated via kies to official jpo ( i also tried jpc, jpm, jp6) and my phone still hangs sometimes. is it possible thats just a strange behavior on sgs with o2 germany?
or is there anybody else (other country or carrier) getting the same issues?
i get this bug every third call (when calling longer than 30 minutes)
....
hmm.. perhaps we found something that causes this o2-bug... There is a discussion in the german forum android-hilfe and there is mentioned that the homezone-indicator signal might be the failure, that you might have enabled.
So what about you? Have you also enabled this feature?
Today i called the O2 hot line and they told me that O2 did not receive the Froyo update from Samsung yet. So they haven't had a chance to test the Froyo release. That mens we have to wait for Samsung to give the update to German carryers for testing. I mean if they encounter the problem too they will fix it since it is a real annoying bug.
Look also at this boards and threads about the same issue:
ht_tp_: / /_ww w._ handy-faq._ de/forum/ samsung_i9000_galaxy_s_forum /174359-probleme_empfang.html (german, translate. google. de may help )
ht_tp_:_//_forum._o2online._de/t5/ Handys-und-Zubeh%C3%B6r/ Galaxy-S-Froyo-o2-WCDMA-massive-Probleme/ m-p/58562#M7640
(remove spaces between first parts of the links, as - unfortunately - I'm not allowed to post links cause of my "newbie" status )
I've got the same issues (hang after/while phonecall, aborted call, no net service and so on..)
Same problem here!
BUT mine locks up every 30 Minutes!
And I use drei.at (Austrian Provider) NOT O2.
So it seems, that its not a specific Problem within O2 only
Andy
happened to me once...but SGS unbranded with O2 sim...
Hey,
i have the same prob. When the phone lies all the night and some1 wants to call me at the next morning i'm not reachable. every morning. 100%
now i installed the i9000xxjm3 modem. lets see if it fix the prob;-)

Hi,
there is finally news on that.
O2 meanwhile confirmed the issue to be connected to the homezone display in the Froyo firmwares.
They propose a solution where they delete the homezone data from the SIM card without affecting the homezone functionality as such. Just the homezone icon will not be displayed anymore.
So the assumption it has something to do with the O2 homezone became true.
Here is the thread (sorry, its German) in the official O2 forum:
http://forum.o2online.de/t5/Geräte-...-o2-WCDMA-massive-Probleme/td-p/45714/page/27
I just wonder if some clever developer here could even remove the homezone icon functionality out of the firmware. I somehow do not trust O2 to come up with their solution quickly enough...
Thanks
Andi

My Omnia 7 keeps loosing it's 3G connection

My Omnia 7 keeps loosing it's 3G connection. To restore it I have to restart the phone. T-Mobile say that this happens from time to time, but it's happening every day now. It's annoying as it stops my push email from being up to date, and of course prevents the use of any internet based services until the phone is restarted.
Has anyone else noticed their phone has switching to GSM?
Had mine for 6 days.Been fine up until today,then I had the same problem.Only the once so far.
Confirm loosing 3G
Confirm loosing 3G connection, and also have phone call failures.
Factory reset did not solve the problem.
Bring it back to shop
Blackstone is back now!
At first this was occasional with my phone, then more frequent, and it's all the time. If I want to use the Internet I have to restart the phone. My house is covered by full HSPA, but the only way to get it is to take the battery out while the phone is switched on. I can sometimes get 3G by a simple restart, which I lasts about 40 minutes.
I like the phone, so I'm going to hold out for a software update. All it needs to do is check available networks and I think that, if this is a wide spread issue, Samsung/Microsoft will fix it. Hope so.
Please post here if you have this issue too.
I have also been having this issue... sometimes it doesnt come back straight away when i restart it but after about 10mins its back.
When I activated it with orange I was told to expect a few txt msg's that would need deleting and the phone restarting... I only got 1 msg, maybe this has something to do with it, maybe the phone hasnt been sent enough updates.
I also have this issue and have done for weeks. Orange couldn't solve it either.
It only happens overnight at home. I either need to reset the phone / rescan available networks or turn flight mode off and on again for the connection to restore.
I was thinking it may be an issue with t-mobile since it only happens at my home where orange signal is poor and i roam over to t-mobile.
If i stay in an area with good Orange signal i don't get the problem.
Good to know i'm not the only one with this problem. It's very annoying!
Hi y'all.
I had the same problem: 3G was lost every time. I was fed up restarting the phone every time, so I looked for another way to get 3G back. I found out that disabling and enabling SIM security (phone > setttings) got me 3G again... for a short while.
But: after disabling SIM security permanently, 3G kept on going (in fact for over a week now).
I think that changing the PIN to some other number, might cause this. I haven't yet tried changing it to the default PIN again, to see if using that for SIM security solves it. For the moment I'm too happy it works again.
I have suffered from poor reception issues ever since I got my Omnia 7.
It seems like the reception comes and goes. I will receive e-mails, which proves that the phone has been connected, but as soon as I try to use data myself, by visiting a web page or refreshing an app like facebook, the reception disappears and the "no reception" symbol drops down from the status bar.
Also, often when I try to send an SMS, it will appear to have been sent, yet 10 minutes later I will receive a "Can't send...try again" message. Once I have received this, the SMS will never successfully send. However, in the meantime I can receive SMS messages, which shows that the phone has been getting a signal.
This is SO frustrating and is ruining my experience with the phone.
I have posted requests on the Microsoft Answers forum and the only suggestions have been to reset the phone or turn WiFi off. Neither of these have had any effect. I have never enabled SIM lock.
I have heard that there is a firmware update due soon which includes a new radio stack. I am desperately hoping that this will improve the situation, as at the moment I cannot rely on my Omnia 7 as my only phone.
Alex.
Hi Loco,
You are right in saying that social answers doesn't really help much .
Luckily there IS a new firmware from a couple of days ago! Check out the Omnia 7 Dev section. There are only a few posts.
And here is also a good link for you. You are right to assume that it comes with a new radio stack which improves on performance.

Finally found a thread on this... I have been having a similar problem since I got my phone from Optus here in Australia. I took it back and they replaced it for me but the new phone is exactly the same. I don't lose the 3G icon but anything data related just ceases from loading. Right now I'm trying to refresh the Facebook app and it just comes up with 'Unable to connect', even though I have full 3G reception.
I flashed it to the newer leaked firmware and it hasn't changed anything, problem still persists unfortunately. This is a major problem that isn't getting enough attention! It seems quite widespread and Omnia 7 specific.
Had similar problems, but after I changed my provider ( O2-Germany), 3G is stable.
For the people having this problem, have you tried setting the phone to prefer 3g? Details of how to do this are here http://forum.xda-developers.com/showthread.php?t=915813

Same here man. On Optus and my reception sucks with this device. What the hell is samsung doing? FIX IT!
I have been having this problem with my Omnia 7. The frustrating thing is this is a replacement phone I had for an LG which I had replaced THREE TIMES due to random resets. So now I have a phone that I have to turn off and on EVERY MORNING in order for the data connection to start working again. Needless to say I am very frustrated. I am on Orange in the UK. I suspect it could be related to when being an a poor reception area and it tries to switch to tmobile. I am going to try turning roaming off. Please, if anyone finds a solution to this let me know.
Thanks

My problem got worse with the Mango update. I'm now on my 2nd handset after having a replacement from Orange warranty. This one still loses it's connection but much less frequently.
TBH i don't think it will ever get fixed. I started an MS Answers thread months ago and lots of people had the same problem but we never got a response from MS.
Conisdering the age of the model now I doubt Samsung care, well they didn't seem to care a year ago so they won't now... For this reason I will not buy another Samsung phone. It's infuriating.
Looks like I am stuck with it until December then when I can upgrade to a Nokia lumia. A long wait :-(
i have this issue, too.. but for me i only have to set airplane mode on and off. sometimes i deactivate data connection, go to a random website, get the 'no connection' error, then activate data connection back and it works.
however, after installing the latest drivers & firmware, i get this issue A LOT less frequent. like once in 2-3 days.
i hope ms or samsung will fix this because it can get really annoying. especially when you need eg. a quick google-search..
Just flicking the flight mode wouldn't be so bad but that doesn't work for me, I have to restart the phone each time. I love WP7 but this and the other problems with the LG is driving me nuts. Almost wondering whether I should have just followed the crowd and gone for an iPhone.

Same as me - Flicking flight mode on-off doesn't solve it, needs a soft-reset.
Like I say, there are quite a few with Omnias on Orange with this problem.
I'm in the same boat, I've had this for months now so I guess I'll just deal with it until I can upgrade the start of April and get a Lumia (hopefully the EU 900/910 will be here by then!). There is no way on this earth Samsung are getting any more of my money. Nokia seem fully commited so they can take my cash next time!
I have the same problem with the data stopping working on o2 in the UK. But I also sometimes cant receive calls even though the phone has service, then there are the times where it site there going GPRS/3G/3G+/No Service and you cant do anything with it apart from pull the battery.

[Q] Signals Problems after 4.3 Official Update

Hello all!
I'm from Argentina. (Excuse my poor english)
I have a full stock S4 i9500, bought to Samsung (without any carrier logo, unlocked).
During christmans night i received a notification about a new update available, i just downloaded it and installed it. Phone is now on 4.3 (Knox and other stuff are now available).
Since that update, the mobile signal is working very bad.
Every 2 or 3 hours signals completly goes off.
If i restart the phone, or turn on/off airplane mode, signals come back.
If i just leave it, takes more than 1 hour to recover signal.
This is becoming very annoying, since i uses sms a lot with my girlfriend (she don't like smartphones) and also, im loosing a lot of calls during signals fails (when signal come back, i ussually receive a lost call message).
I searched forums for this same problem, but i just found people who had stock problems, and in my case, problem become with the new update.
I want to avoid full factory reset if it possible.
I can post any screenshot if needed!
Im sorry but one solution can be make a factory reset. Only make a SD Internal backup to ur pc before do it and is all

[Q] S4 - disconnecting from network and not reconnecting again

Hi all,
Regular reader but hardly ever post!
I have a Galaxy S4 (GT-I9505) - with Android 4.4.2. Unrooted.
Purchased and used in Singapore on the Starhub network since around October 2013. Everything was working fine until approx Feb or March when the latest Android version, 4.4.2 got rolled out.
Ever since then I am experiencing regular disconnections from the network. But the phone does not re-connect back to the network again, the only fix is to restart the phone.
These disconnections are often once or twice a day, and are very frustrating because if I don't notice it, I may be off the network for hours before noticing it - and are therefore missing out on calls emails etc etc.
This only happened after the Android 4.4.2 got rolled out, so I am pretty confident this is the cause of the problem.
What I tried myself to fix:
- restore APN's back to default state
- Factory reset (both via settings, and via boot screen)
What I have been able to narrow down troubleshooting, is:
- Disconnects seem to only happen when Network Mode is "LTE/WCDMA/GSM (auto connect)"
- If I use network mode "WCDMA/GSM (auto connect)" the disconnections have not happened (yet!)
- When the disconnection does happen in the first mode, I cannot manually change the network mode. The radio buttons are greyed out, and if I try to select "WCDMA/GSM auto connect" the request times out (I forget the exact message - it does respond to the tap but then nothing happens)
So it seems to me this is some sort of software bug/fault introduced with Android 4.4.2 that affects 4G connections.
After that, I have taken it to Samsung for warranty service. I have now had 4 visits to them and they have not been able to fix it yet. This is what they have done so far:
- First visit - factory reset (despite telling them I already did that) - did not fix
- Second visit - checked hardware and replaced mainboard. Did not fix.
- Third visit - checked hardware again and factory reset again. Did not fix.
- Fourth visit - who knows. I think same as visit three but done via a Service Manager instead of staff, Did not fix.
When I first called them back in Feb or March, they said it was a "known Issue' and sugegsted to "wait for a patch". However since visiting them, they said the known issue was only with Note 3's (not with S4's) and replacing the mainboard on the Note 3's fixed the problem. In my case replacing the mainboard - twice - has not fixed it.
I'm getting very annoyed with Samsung who seem to just be trying the same thing each time and are not fixing it. Staying in 3G only mode is a workaround but not an acceptable solution.
Now they've asked me to take if back again - for a 5th time.
Beginning to wish I had never bought the S4, or at least never got Android 4.4.2.
So I thought I would turn to here for help instead, I think you guys and gals probably know more than the Samsung service staff!
Any suggestions?
By the way, I don't run any memory/battery saver apps. I do run one data usage monitoring app that I thought perhaps was conflicting, so I tried not installing it after one of the resets, but the problem continued.

you CAN try other modem flash, but be careful with your warranty.
I do not know about the warranty conditions in your country, but in EU normally 3 unsuccessful repairs = phone refund or replacement.
I would try reflashing stock file or just flash a different modem
Hello, just like you i have been reading the post but never posting because i just came here to learn, nothing to share from this side...sorry.
But i am having the same problem as you. I bought my phone in Switzerland on march 2013 but i live in Uruguay. I was just thrilled with my s4 until the 4.4.2 update came out. My connection keeps on crashing and it doesnt matter if its on 4g or 3g just make me miserable all day. Only the two of us is having this type of problem??
I believe is some kind of issue with the new bootloader i just updated with a patched rom that came for Germany last week (the one with kids mode) the phone work fine for a hours and then crashes, so this update didnt work. I have also flashed very differents official roms and modems but nothin seem to affect the problem.
I have another problem even though my s4 is 4g i cant connect to 4g network, every configuration is fine i just cant connect, any thougths??
Thank you very much.
Sorry for my english.

I should add, I took it in *again* to Samsung, to the Service Manager. Said they would replace the antenna and try that, which they did.
Still have the same problem though.
Not sure who to believe, Samsung are starting to run out of ideas and starting to say it may be a network issue. But if the network is down, then the phone should automatically reconnect once the network is back available again. And it doesn't.
I'm convinced it's a bug introduced with KitKat, as the problem only started then, but of course I cannot prove it...

Sounds very similar to my problem, that it just started with Kitkat only. I'm sure it can't be just us two having this problem! I don't have anything special or different installed on my phone, and it's too suspicious that it was working fine, 100% perfectly until the KitKat software came out...

I know it just cant be the two of us from such diferent places in the world but, i just cant find any similar in any post or google. It has been almost 3 months from the update an me using another phone...
Well I thought I would post again to close the loop.
After Samsung tried 5 times to fix my phone, checking hardware and trying to reinstall the OS with no luck, they suggested I try replacing my SIM card.
Surprise surprise, it has fixed the problem with no recurrence yet after a week so far.
I still don't understand how the sim card could be the problem, especially as my phone was working perfectly right up to the Kitkat software update. All I can assume is somehow KitKat either had an incompatibility with my simcard (maybe the new sim is technically slightly different?) or maybe KitKat somehow changed something on the simcard, if that's even possible.
Interestingly, I did contact my telco first, and they told me to contact Samsung. As it turned out, the fix was in the control of the telcom right from day one.
Anyway, so far the problem is resolved, so I thought I would post this here to help anyone that may have this problem.
