Mobile Internet connection - Galaxy S 4 Q&A, Help & Troubleshooting

Hi, sorry for disturbing, I have a weird connection problem and I am pretty sure it is not the internal antenna... When i use the phone for Internet, mail etc etc.... Everything goes fine it uses a 4G connexion and I almost never have a problem, I do have a problem Sometimes when I am not in a 4G covered area... Than i have to change the network modus to wcdma /gsm automatic because if I leave it on lte /wcdma /gsm the phone is jumping all the time between hspda /h/edge gprs... And this goes fast like that that connection fail... This problem stops when i change modus than I get a stable 3g connection.... A little bit disturbing but Okay..... The biggest problem is that I m always connected with my messenger services like for example WhatsApp.... When i have the phone in my hand no problem at all.... But when he stays on the table or in my pocket it is kinda weird.... Sometimes I don't recieve my messages and than suddenly when I pick up my phone I get like ten messages in once starting from like half hour before.... All this started like three weeks ago, network provider say there are no network problems, I didn't drop my phone or something... Internet connection is just acting very strange lately and this started before I updated to the official 4.4 rom and didn t change after...... I also have to tell that I don’t have problems at all with phone calls or texts messages..... It's just those two mobile Internet issues.... Since i m only good for using the phone and don't know nothing about the technical parts or something... I wanted to ask the question to all of you experts.... And wanted to ask for help and if possible a solution? I want to thank you in advance and hope you guys can help me soon.... Kind regards...

Try different modem perhaps?

Hi thanks for answering.... Tried everything.... Still same two connection problems..... Only thing I didn't do yet was a hard reset.... Could this problem be caused by an application or a bad uninstalled application? Thanks in advance

Hmmmmm, highly unlikely from my point of view, but however there could be some apps locked into 2G or 3G or 4G connection.
Try how clean system doing, if it's same, consider it a hardware problem which there is nothing we can do about it...

samsung s4
i am having network issues
wifi works good
2g works good
3g/4g doesnt work at all no signal if i select these networks
is it a modem issue or kernel issue

Xepria X10: 3G APN not working but showing 3G on the top bar.. suspect juicedefender

Hi
Allow me to vent. I am not a very satisfied customer. I am having a lot of problems with this device. the most irritating being the battery life as well as 3g function. After reading up about the battery life problem I installed juicedefender. Not a bad app for what its worth, only if it worked correctly. Ever since I installed it, it has been causing issues with the APN which is apparently a known problem. The APN does not turn on fully? I have now uninstalled it but its causing intermitent internet connection problems still, cant seem to figure that one out.
Anyways, I can see the 3G and H icons on the top bar showing activity, but nothing seems to work. I can't browse, no other applications really picking up any data at all. I have loads of apps that need to be connected all the time.
Anyone have any ideas on how to deal with these issues? I am really getting annoyed now. I tried out a mate's desire, it seems so much better and faster.
There are lots of other issues I am facing but I wanted to keep this thread focused on the most troubling issue, the 3g connectivity.
Please respond with suggestions.
Re: Xepria X10: 3G APN not working but showing 3G on the top bar..
I would start with a factory reset. Failing that, reflash with SEUS.
Hi -Which network are you on? try deleting the APN and re-setup the internet settings.
reluctant to do a factory reset. Got too much stuff on there. I have switched to 2g and its working so far, but not ideal obviously. I am stuff with 2g and a battery life that doesnt last 7 hours. I am not pleased at all.
I am on t-mobile UK

Reluctant or not I would do it, looks like juicedefender screwed something up, or you have a hardware issue like a bad antenna. When your phone battery drops below 15% and the phone prompts you click "why?" and let us know what the results are. I have been using my phone all day today for the past 14 hours and have 45% battery left not using any juice defender (which I think messes with Android)
Delete the A P N
Did you try deleting the Apn's and re creating them? it's really easy to do and won't lose any of your other data or config off the phone.
-------------------------------------
Sent from my X10i
Occasionally I have this same issue. However it only started happening after I debranded my handset and upgraded from 1.4 to 1.6. I have not installed juice defender whilst being on 1.6.
I did have to recreate my APN's but my data connection started working immediately afterwards. I've noticed that it drops every now and again without warning. When the connection has dropped i still have the 3g\H symbol.
I am on o2 in the UK and had the same issue after using juice defender, basically it changes your APN by inserting it's own APN text. Even after uninstalling the app it doesn't delete it's settings.
All you need to do is recreate your APN settings, I am sure you can get them off the T-mobile website.
does anyone got the APN setting for T-Mobile (USA). my phone doesn't show any data signal.
Thanks.

Found your problem.
iead1, if you had read my post correctly, I uninstalled the app as it was causing the issue. The 3G stopped working altogether after the uninstall. Had to delete the APN and recreate it with the same settings. That fixed the problem.
Re: Xepria X10: 3G APN
Had the same problem. Juicedefender edited my apn to juicedefender.live.vodafone.com and because of that no internet access. I just deleted juicedefender and reset my apn to get it working again

The X10 can't do traditional video calling. It doesn't have a front facing camera.

[Q] No service sometimes .

I sometimes lose service and it only comes back if I cycle airplane mode or reboot phone. This happens in places were I have great signal . even when the phone shows no service I can still make calls but can't text and if people call me goes to voice mail. This happens on every build, radio, and rom I have tried. I don't see this as a known isue in the forums . Any help would be great . Also thank you to all whom contribuit to these android builds awsome work!
Resurrection!
It's beautiful to revive some old dead threads!
I have here the same problem with my NAND build!
Can anybody help on this?!?
10x
yes I have the same problem, this can be resolved by setting the mobile data network to 2G only.
The Android build has this problem on some providers when trying to use 3G data mode.
Here in Belgium, this problem is there with Mobile Vikings (Base)

Thanks bro but unfortunately i'm 2G already!
I had this issue in the past! I don't know what made it go and now what made it come again!
Any third party apps that can cause the problem?
I have had this problem for a while. It will just randomly loose connection, you cycle airplane mode and then your service is back. Its almost like the phone isn't looking for a new cell tower after it loose connection and cycling airplane mode causes it to search again...
Extremely frustrating problem as it happens often and has been for a while (on many different builds and radios)
If anyone knows a fix or something, you would be my hero haha
And, what about the problem?
I've the same problem, but my network comes and goes..
one time i have reception, and suddenly its gone. autmaticly it comes again and on and on.
I'm a match ringer, i know
Nobody has this Problem too?

Phone loses connection!!! Please read!

Hey all, I have a little (or a big) problem. It is so, that my phone sometimes loses connection. Than I can't call, send messages, go on the internet. So now to my question. Does anyone has/had the problem, and is/was able to solve it?
I wouldn't like to give my phone to samsung, because my imei corrupted (I don't have a backup of my /efs folder), I have flashed several times, and I rooted it several times XD and I don't have a backup of my orange fw (I live in Austria).
So please help me (if you can)!

WHich version do you have? Is there a specific time when phone loses connection?
I had connection loss problem and that was related to mobile internet. You can try to disable mobile internet and check.
For Original ROM, go to samfirmware.com and download the original ROM, update your phone to orignal ROM and go to samsung service center and tell them about IMEI loss. Just show that you dont know anything
I have lestatious v1.7. I know samfirmware, but there is not a version for orange branded gt i5801^^ but ty for your quick answer^^

sometimes i get disconnected... what i do is go into the plane mode and come back out... connection restored...
It started doing this after i got my mainboard replaced... so could it be hardware related?
It happens with me also sometimes. Going into airplane mode and coming back doesn't help. Restarting doesn't help. Replacing sim doesn't help. Even inserting another sim doesn't help. Only fix I have found is walking over to a different area physically. Atleast about a kilometer or so and it latches on to the signal.

3G works like on-demand

Hi All,
I have been having problems with my S3 for some time now.
HSDPA. Sometimes it works and sometimes it does not. It works as if it was set up to work on demand.
Where could it be set up like that? I have checked every menu and cannot find anything.
Help much appreciated.
I don't understand, do you mean it keeps switching between 3g and H when you ate using it and not using it?

HSDPA works and in a few seconds stops. No data at all. Then HSDPA works again for a few seconds and so on. No pattern or anything. I tried to keep it running by keeping Skype work, but it would disconnect from data completely again. It is connected to HSDPA network and I can make calls over that, but no data.
Sounds like your being ping-pong'ed between antennas.
Usually flashing a eastern modem (I can recommend the ZN... ones) should fix it since they are optimized for large cities which have this issue.
Also, having a proxy server configured in the APN settings may cause this issue if it's overloaded and causes connection resets.
If you have one configured, write down the settings(in case you need it ) and try removing it.

Some good ideas.
Heading to the modem collection thread.
No proxy in APN.
An interesting thing is, that I went to another city a few hundred km away and everything was ok, so I thought it was the phone and it started working again. I am back in my area and it is happening again. The only thing is, no one else is having these porblems, even people using S3.
EDIT:Just fashed ZNLH3 using CWM and will start testing. Right after starting the phone, there is no data active.
EDIT2: I forgot to mention, that when I switch to GSM only mode, EDGE works just fin, no disconnects at all.
Try fast dormancy apps from play store and disable it.
The switching between hsdp and 3g is not a problem. It is a technology to preserve your data usage when you are not using.

There is no problem switching between 3g and H, there is a problem with switching between HSDPA and NOTHING.
ZN modems did not work.
Will try fast dormancy, the setting was not available in the ZN modem under *#9900#. Will try LH1 and Pay Store.
EDIT: FD switch installed and FD disabled. Will do some testing and report back. Working on LH1 modem now.
If you still have suggestions, they are more than welcome.

Position has not effect, it happens wherever I am.
I will try with ping and see.
EDIT: PIng seems to make the connection persist. Will keep it running and see.
Been running ping for over an hour now and no data cutoffs. Means there is something that keeps disconnecting me.
How do I find out what and fix that?
To answer my own question:
I instaled DLI1 last night and so far in almost an hour not a single data blackout!
I was wrong blackouts still happen
Using DLI1 and FD switch, it now works much better, but there are still blackouts.
I will look for the GSM Monitor software and see if that can help me identify the problem..
problem is your location ur phone is jumping between 2 bad signals/towers and one of those towers does not have 3g on it only 2g
I say this because I have same problem at home. certain areas of house amazing 3g reception others .ir does not work and ye so .ir flicks between them and I often eexperience "blackout" . .signal says on H but no data throughput.
try downloading gsm monitor from play store will show u how string signal is and which tower it .
hope this helps

I'm pretty sure that disabling fast dormancy will fix this. I've seen people with that problem before and was fixed instantly. Search the forum for the fix. There is a file you download to insert that will fix it.

Of course, I have had it set up like that since the beginning.
Remember that my problem is not with constant switching between HSDPA and EDGe, but with switching from HSDPA to nothing.

Terrible wifi connection on note 3!

Has anyone else been experiencing this. I am connected with BT home hub and it's awful. Connection drops literally every few seconds. It was fine with note 2. Any soloutions? I really like the phone but these small glitches are making me angry now. First it was stock browser which I have stopped using in favour of boat, then the biggest selling feature S pen it's sensivity was really bad I fixed it by adjusting the potentiometer and now the wifi signal. I really hope there is a fix for it.

Works fine on a Netgear router...
Some routers have issues with newer phones. (and some with older ones, as well.). Have you tried updating your router Firmware? Reset your router?
Also, set the connection type to Static, not DHCP.
i was thinking it was the modem but my s4 works fine.. already called EE about a replacement..
mine works fine.. better then my old device!
my Netgear router is located on the first floor at the front of my house (in the office). in the master bedroom ensuite i got like 1 bar on my old device..
now i get full bars..
I live in a newer development area and i am on the boarder of LTE coverage.. on any other device i get 4G in my house.. now i get 2 bars of LTE..
pretty satisfied..
now speaking of software jitters and such.. that's a different story
Mine works great

WiFi access points don't get better with age. The hardware is upgraded constantly and even firmware updates can't change the hardware. An old WiFi access point of 2-3 years will not work as well as the newer ones do.
WLAN connectivity and speed is real bad on a fritzbox 6360 cable (fritzos v05.50). Sometimes full speed with ~4+ mb/s, a bit later resends and timeouts all the time. foldersync is a pain over wlan. today i needed 1h+ to download my apps from playstore after flashing omega rom. Cabel connection speed 100 mbit! 2.4 ghz or 5 ghz, static ip - no changes hope there will be a modem update for the note3 or a fritzos update that fix it.

what was the problem you had before the update?
Went into a coffee shop. Where there is free wifi if you buy something. It was me and a friend. My s4 had full signal. And my new note 3 struggling to get connection it kept saying checking quality which is really annoying. Anywhere my s4 gets connection the note 3 checks quality and drops. Im right next to the router at home and this note 3 wants to check quality of the connection. Never had a problem with the s4.
