After some investigation, I believe the data connection loss for me on 2.2 seems to be related to WiFi. If I have WiFi on and connected and leave the wifi area (elevator) it seems that's when the issue occurs. To test it out, I have been turning off Wifi while still connected and I'm heading out. So far I haven't lost data connection since i've been doing this and I specifically did things that led me to lose data connections in the past.
I think the software believes the Wifi is still connected when its not and thus the 3G data doesn't come on properly.
I'll post back if I have the issue but I'm continuing to try this and hope it works. Nothing and I mean nothing else appears to be an issue for me apart from this thanks to fixes and my good luck it seems.
I have had the same issue. It doesnt happen all of the time for me. It happened right after installing the ROM. I rebooted and it solved the problem. Since Friday, I have had it happen twice. Prior to replying, I turned off the WiFi and the phone switched to 3g without any problems. I'm trying to reproduce it....I think my problem occurs after I have been charging the phone with WiFi on-like it gets stuck. I will not know until in the morning. Like I said, it hasn't happened but twice.

Further testing and I think my theory is true. No issues still. Usually by now I have the problem.
I am running .588 and I restored my data after coming from the original gb (.573) leak. I loose my 3g connection at least once a day. Sometime when I toggle the airplane mode it works and I connect back to 3g, but i that does not work I just reboot the phone. Anyone else having this issue? We need feedback to see if its a hardware or software issue in gb. The reason I cannot confirm if it is s/w or h/w issue I received a replacement phone when the .588 came out. I cannot compare both builds with same device. I am going to revert to .573 to see if it continues. I will post back with outcome.
Thanks in advance

I have had this issue also. The toggling of airplane mode usually works for me too. Although yesterday it didn't and I had to reboot the phone.

The airplane mode does not work for me. Someone recommended to use an app called signal refresh. My main concern is if its a s/w of h/w.

I have this problem, as well. I used the Monster SBF to get to .340, installed GB, and restored only user apps with Titatium Backup. Airplane mode works for me sometimes. Every now and then my phone will go into airplane mode and lock up, forcing me to do a battery pull...
I was on the old gb leak and restored data in clockwork after moving to the new gb. I haven't had the problem yet today. (Knock on wood)

I'm seeing the 3G drop as well. Of course i only notice it since i'm tethering my wifi xoom to the droid (method irrelevant). Airplane mode works for me.
Mine drops out and stays out all the damn time. Sometimes airplane toggling is enough, sometimes I have to re-boot the phone and then toggle airplane mode and other times just turning WiFi off works well enough. It happens on my Wife's D2 constantly as well. We've missed plenty of calls (google voice pops up letting me know I have messages from missed calls even though the phone didn't ring and we have big problems texting throughout the day).
We're both going back to Liberty right now cuz this is BS. Hopefully this will get fleshed out for the final OTA and I can see why Verizon hasn't approved either leak yet. And even more hopefully it's not the new radio, and if it is hopefully SBF-ing back to 340 will fix it. If it doesn't, do any of the older SBF's work with the 340/588 bootloaders and also contain older radio firmware?

Update:
re-flashed GB. went two days with no signal problems, but this morning I lost my 3g connection. I have a feeling that it has to do with the hand-off between the wifi and 3g connection. I have tried to duplicate the issue but I cannot duplicate it. Also one thing I notice is when my 3g is not working and only shows the 4 grey bars I cannot make outgoing calls but calls do come in. Weird....

I have been running into the same issue on both of the leaked versions.

I have been searching and reading and I have notice a couple of people are having the same issue. Have you tried to call your phone when the 3g is down?

It's one of the issues. Not fixable now.

Its a known bug? I have looked everywhere to see if people were having the same issue and couldn't find anything.

I am getting this also on the leaked GB :/
Took me TWO reboots to get 3G back!
Yep, it's all over. Despite what some may claim, the leaked GB(claimed OTA) is not without bugs.

has anyone noticed when this happens that your 3g icon and the signal bars go from blue to a white/grayish color? i have to reboot mine eveytime and then it works perfectly fine for another few days.....
Mine do that, but they turn blue one I starting using data
So I recently updated to the OTA rooted 2.3.3 by clearing all data, sbfing back to 2.2 and then updating to 2.3.3 OTA rooted. I have noticed recently that every other morning or so my data connection is just gone. I can turn airplane mode on and off and it does not come back, wifi works fine. However if i disconnect from wifi I get no data and I can't make a call or send receive text messages until after I reboot, just wondering if anyone else has been experiencing this and if there is a solution or if I should just clear the data on the phone and see if the issue goes away.
That is not good. You may want to SBF again to see if that works
I have the same problem on my non-rooted droid x. data connection goes away and doesn't ever come back until you reboot. I've seen other people have this problem in a few other forums also...
Well I did a factory reset and install only launcher pro and google voice. Will use like that for a few days and see if it happens again.

I sorta had this issue last week -- mine was dropping from 3g to 1x in my daytime location --i am here everyday so I'm familiar with the speeds/signal strength for this area.
Also I had never had this issue... ever. I was on the .595 GB leak, but I sbf back to .340 (didnt root) and STILL had the issue. I did data and cache wipes in recovery while on .595 plus a factory reset even after the froyo SBF.
So nothing worked..... GB, Froyo, rooted, non-rooted, factory resets, data roaming disable ... it still would drop 3g for 1x. This was just out of the blue, I've had the phone since Dec. 2010
I thought it might be a tower issue, so I suffered with this nonsense for 3 days, knowing that VZW would likely fix tower issues in that time.
After additional research, I found those saying a battery pull would do the trick. Well heck, after all that angst and effort a simple battery pull did it !
Not one problem since. Try the Battery pull !

I'm having this occasionally as well.
Curious as to why a battery pull would do anything different than a reboot?
FWIW I'm on .596 rooted

It isnt any different. I've had this happen a few times and it keeps coming back in normally bad signal areas, but not every time. I have also had random reboot when the phone is in my pocket, unlike froyo where the reboorts happened when I was doing something important. I suppose that is progress then.
This is my 3rd Sprint S4 over the past few months. All of the devices are loosing the 3g icon but will show bars. Voice and text works fine, data and 4g does not, i have noticed it usually happens when i leave a WiFi area and it has trouble switching back over to cell data. I can reboot the phone and about 80% of the times it will return to normal. I have used odin to reload to factory. I had my phone rooted only and recently install the Triforce rom to see if it was a software or Kernel issue. Same thing is happening on that rom as well. It doesnt matter where i am so i dont beleive its a tower issue. Any idea?
This happens to me as well. Just Sprint being crappy. Try turning airplane mode on and off, same effect as a reboot but faster.
I tried the airplane mode toggle but didnt seem to fix it. If i use even the "Hot reboot" option in triforce rom that doesnt fix it either.
Assuming this this is the same issue I always experience, there is no fix. It's a network thing. Is there 4G in your area?
What happens to me is my phone will be on 3G, then start receiving 4G, but it doesn't recognize that the data service is now different, so nothing works for 15+ minutes or until I toggle airplane mode on/off.
I take it you've tried just turning WiFi off?
Haha, yea, welcome to Sprint. Enjoy losing data when it's least convenient (such as when you need to use navigation or missed your exit and need to be rerouted). Oh well, the price we pay for unlimited data, right?
I have noticed the same thing since I activated my LTE radio. LTE is expanding in my area so I constantly go in and out of 3G and LTE service. Sometimes when this happens data just ****ing stops working until I enter airplane mode and then come back out of it (a reset works as well). For some reason (or it is just a coincidence) The problem has amplified since installing 4.3. Has anyone else noticed an increase in this problem since upgrading? This is absolutely a Sprint problem? Do we know that people have this same issue with other Sprint phones?
I have the same problem. From wifi to f data takes a little bit of time for it to switch over especially since the data toggle is gone with the 4.3 update. Unlimited plan is water downed from my experience compared to tmoblie. But tmoblie service was horrible.

Well Sprint's speed has always been an issue for most of us. That is no surprise. I at least expect to to work AT ALL which apparently it is incapable of doing recently.

If wifi is on 3g/4g is not there,, turn off wifi and you should see icon,, if you see bars it's most likely working :sly:
Edit just re read your post, I have the same issues sometimes and as posted above toggling on and off typical works for me,, good luck
Also is your network set to
CDMA/LTE/EVDO? Just throwing out ideas

I get this issue all the time & I have to do a battery pull to get my phone working again. Anyone flash a new modem which fixes this? The SGS4 is 10x worse than my HTC EVO 3D was with this issue.

Seems like a hardware problem based on your description. I am fully convinced that this whole flashing modems things is just a feel-good measure for people who have exhausted all other options. It was big in the Galaxy S2 days, but I have never seen any measurable difference between modems in any meaningful metric on that device. At least not one that could not be attributed to other factors such as signal quality and network load, and nothing consistent. A different modem isn't going to fix a hardware fault or magically improve Sprint's awful service.
I was just wondering if anyone else has problems with their LTE dropping to 3G out of the blue. This happens when I am at home in a really strong LTE area. My wife's Nexus 6 doesn't do this, it stays in LTE. This only seems to happen to me when I am at home.
I am running the latest PN ROM, latest vendor and gapps, and I have tried numerous kernels. Both my wife and I are using the Verizon sim through Straight Talk.
Thanks for any help or ideas you might have.

I've made a post that mentioned this. There is a issue affecting only the Nexus 6p Phones. Google supposedly fixed the issue. Although Some seems are still having issues. Apparently it's stemming from the GPS. They have a workaround that's helping some. Have your carrier clear your location, disable your GPS, Reboot phone. Uninstall updates for Google connectivity services, and try to update it. And again reboot.
I continued having issues even though they fixed it, so I went cleared out system reflashed stock images, rebooted, via mskip toolkit. Been running pure stock except root, and been working fantastic with no issue. Hope this answers your question. Good Luck!
This has happened to me like... Once or twice since I've owned my 6P (~7 months) on Verizon (Non-MVNO VZW). Flopping airplane mode, Forcing the modem to reassociate would get it to jump back on LTE. The issue I've had more frequently (20-30 times since purchase) is the phone just falling off all data completely.
If VZW LTE coverage in your area is good (It's insane here in Florida) I'd recommend trying forcing LTE only.
Dial *#*#4636#*#* from the phone dialer. Then under the "Phone Information" menu. Hit the drop down that should currently say "LTE/CDMA/UMTS Auto (PRL)" and set it to LTE.
This is going to cause one of two things.
1. It'll fix your problem, Meaning it was actually some kind of provisioning/priority issue. Your phone for some reason couldn't hang on LTE, So it fell back to 3G to maintain connectivity. Even though it would've worked if it would've tried LTE again.
2. You'll still fall off LTE. But this time, Instead of falling to 3G, It'll disconnect completely.
If it ends up being #1, I'd try swapping SIM's with your wife for a day or so, Just to see if it follows the phone or the sim card.
Just started having this issue yesterday.
Before that almost never.
I also just upgraded to the August security path.
Well my calls dropped out 3 times, On Oputs network Here in Austrlia and i was on 3G and good signal, Lastest Pacth and Stock anroid.
