Issue with Network - Losing Networt completely for few seconds while using 3g data!!!

I have an issue where the network suddenly dissapiars when I using 3g data and is back withing few seconds.
I dont think this is an issue with the phone but rather with the vodafone network as the problem started when I went on WCDMA mode from auto mode now I have switched back to auto mode to see whether the problem still exist.
Has anyone else experience the same problem

My gt-i9505 switch permanent from H to H+ and get connection issues or no network error the problem is my german provider 1&1 (vodafone Network)doesn't Support Fast Dormancy i think this causses the problems anyone figured out to disable FD on galaxy s4 without root?

Yes the same thing happens to me I guess its an issue that will be sorted out soon

So no one else from India has faced the same issue ???

I got the same problem with vodafone and i9505 in italy.
I'm actually looking for the code to disable fast dormancy but nothing found at the moment.
Code *#9900# doesn't have the fast dormancy selection in GS4

My issue is also on a Vodafone Network in India unfortunately at first i thought it was a problem with my cell phone but i am pretty sure it is issue with the vodafone 3g network and the way the phone interacts with it.

Yes you're probably right.
Really strange that also GS2 GS3 and Note phones have the same problem and samsung surely knows this behaviour of their firmware. If never has changed till now, I think we have almost no chance of getting an update from samsung.

Never had this issue with my S3, and I'm seeing this behavior on both AT&T (US) and Chunghwa (Taiwan)... with the exact same SIM cards even! There is something really wrong with either the S4 or my handset...!

I wanted to chime in. I have a Sprint Galaxy S4 and I've noticed the same issue with 3g suddenly disappearing and then coming back within a few seconds. I don't ever recall it happening too often with my Galaxy S3. Strange..

Any solution to this its a piss of that I can't use my phone properly also I bought this from eBay called samsung canada they said it's not covered under warranty because I didn't purchase it through a authorised retailer. F**k samsung

I have experienced the same issue since the first date I bought my i9500. Tried different modems but the issue is there. I have to turn airplane mode on and then off to get signal back. It's not a carrier issue. I had the same problem using different SIM cards. Hope they fix it soon.

I find it odd that there certainly is a group of us i9500 users on here experiencing this, but not more people reporting it. Like I mentioned, I'm using the exact same SIM cards as I used on my S3 i9300, and after extensively using them in my S4, I see the exact same network loss issue on their respective networks. Definitely not SIM or carrier related...
Could there be a lot of defective i9500's out there, and we're just the unlucky bunch?!? For what it's worth, my i9500 was purchased from Expansys-USA and was a Latin America model.

You should consider a Samsung related problem. I read a lot of forum and the problem was present in i9300 and i9100 too.
I never had a single network data loss with my previous LG-P990 and now I have a lot of network data loss with the new i9505 in the same locations.

You're not reading very well, we had zero issues with our previous Samsung devices on the exact same SIMs on the exact same networks (mine being a Galaxy S3).
I'd like to keep the wild theories at a minimum and try and get some empirical data on this issue from actual users.

How bad is it for you guys can you still make phone calls or use data. I cant do either i lose service about every 25-30 seconds. Hoping samsung replaces this or comes out with a fix.

its the modem firmware i believe. this always happened during first batch of release.

I really hope that's what it is, I never experienced this with my i9000, i9100, or i9300 though. And, I pretty much bought all of them at launch / first batches.

You right, I'm sorry. Reading too much faster for me :silly:
I really hope that's a modem firmware related problem, but I don't understand why a similar problem becomes on every new phone model. Samsung restarts the firmware development from zero every time for a new phone? I hope no.

[Q] at&t galaxy s4 phone powers off unexpectedly

Hi,
I've noticed in the last few days that my at&t galaxy s4 phone powers off unexpectedly - it seems to be either when receiving an SMS or whatsapp message. I have handcent SMS for messaging. Of note also I have the galaxy gear connected in bluetooth. I'm going to try and troubleshoot the issue but was wondering if Anyone else had a similar issue?
The phone fully powers off requiring a full restart.

what model?

[Q] Using i9505 on Bell Canada

Hi all.
I originally purchased my Samsung Galaxy S4 i9505 in the UK where I was using it on LTE with absolutely no problems.
One thing led to another and I'm now living in Canada, and using my i9505 on the Bell/Virgin network. The phone connects to the 3G network just fine, but does not connect to Bells LTE network here.
Having done some research, I'm led to believe that this is due to the fact that the i9505 does not support the 1700MHz network for LTE, although the similar i337 model does.
I've read a number of topics that state it may/may not be possible to unlock this banding on the i9505, but have not been able to find any conclusive answer on whether it's possible, and if so, how to actually do this.
Any help or suggestions anyone might have would be incredibly appreciated, as I'm sure I'm not the only one wondering this.
Thanks in advance!

[Q] My Samsung S4 att drops signal

Giants,
I have my 32 gb samsung s4 since the end of 2012, however, I have been flashing a lot of roms with no issue. the problem started a week ago when the display has been broken and I changed it. Everything went okay for 3 days, suddenly, it starts to drop signal with no reason. I flashed the rom again "liquidsmooth rom" and I flashed another rom, I even flashed the modem again. I tried to search for the problem, I don't know if the brokee of my display ambact the signal or it is a software issue. Now, I am using liquidsmooth 4.4.4.
I have been testing my Sim card in other phone, it works perfectly. I have tried other sims in my phone it gives me the same issue. another thing I want to mention is that after this problem I have never get 3G or 3g+, I always get 2G or No signal.
Omar,

It's a long shot but maybe your apn settings changed check them. Not sure if it will work but worth a try.

the problem is not only the internet, I even can't make call and my line went off.
thank you for your advice,

[Update]
Dears,
I'm struggling with the phone I don't know if I lost it or I can fix the problem. New thing happened outside of my home I got 3g+ and some time I got 3g. However, I am outside the US, I don't have LTE over here.
Would anyone give me an advice how do I know if it's IT issue or it’s Technical issue.

I've been looking forward your comments guys. Anyone can help?

I'm having the same issue. Any help?

[Q] Any way with sprint to talk and hotspot without disconnect?

Well recently switched to sprint to save money...(yayaya big mistake) picked up a M9 only to find out the new spark network doesnt allow talk and hotspot at the same time. So i did some research and found the that 720 (non triband) S4 galaxy has dual antennas that would allow talk and hotspot without interuption... at least thats what i thought....so I bought one on ebay and return my M9...
So now im rooted with the s4 (odin) and have the wifi app for $2.80 google play store.. and still every time I make a call my internet goes out.
Is there anyway I can access both without interruption on the sprint network? or do i have to add a line and have a dedicated rooted phone for uninterrupted access?
Thanks ahead of time guys, I came here first cause i know your the BEST!

Maybe its the hotspot app you are using? have you tried the hotspod mod on these forums?
also, make sure you're on LTE, as thats the only way sprint phones can talk and do data..

Not if tri-band and on LTE. There is no VoLTE so it will disconnect data when you are on a call. You are SOL.

Yea i know.. im no stranger when it comes to rooting and flashing, but I did a basic ODIN2 root, then added WiFi tether from googleplay store and this is happening, on OS 4.2.2
So now Im about to flash OD2 baseband the
Wicked 10.2 ,
then 10.3 and see if fixes it.
A possible reason why this is happening is perhaps when I recieved the phone I did not have a SIM card for it. (ebay sepcial) So I went into sprint and they flashed a new one onto it possibly to disconnect the VoLTE upon dual usage. Im hoping the OD2 baseband and WICKED rom will repair this.

UPDATE:
flash OD2 and now I have voice and data!! YES
Just flashed the wicked 10.3 rom and now I have no keyboard!...damn
