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.

LOL, you didn't read very well again, my last post:
"I never experienced this with my i9000, i9100, or i9300 though. And, I pretty much bought all of them at launch / first batches."
I just got a new AT&T Galaxy S4 from Amazon for my fiance. It shipped with the MF3 firmware. Randomly, she calls out or receives a call and there is no audio in or out. After hanging up, and redialing or re-receiving a second call, everything is fine. It doesn't matter if she was moving or in the same location. I can't seem to reproduce it consistently but it is frequent enough to mention. Is this common with MF3? Not sure if it's software of hardware related.
Never had this issue on my mf3 gs4 I would replace the phone or have bestbuy reload the software

I have the Samsung Galaxy S4 SGH-I337 Model with AT&T (16GB) and every since I flashed my device using a custom kitkat 4.4.2 rom that is rooted with a tethering add on I have been experiencing problems with my data connection switching from 4G LTE to Edge connection. Also, I am experiencing problems making calls. It takes so long for it to call out. The chime that I hear just before I hear the ringtone can take 30 secs to a minute. It's driving me insane. I just wanted a rooted device on kitkat with tethering. What can I do to resolve this? I appreciate any help I can get with this!
Here is the tutorial forum that I followed when I flashed my device with this custom rom...

hi there,
quite a complex procedure you followed.. perhaps your device has a mismatch in the modem (radio) . I experienced similar signal drops and disconnections when I inadvertently upped to 442 (NC1) while keeping the MG1 modem..

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.
