Anyone else having a problem with the NxS jumping between 2G/3G network all the time?
I tried 2G-only and it seems the it does interrupt connection less often, but it still does. I'll exchange the sim card tomorrow to rule out the last option (I can think of) I got before returning the NxS and asking for a replacement.
(i9023, stock rom/kernel/radio, tried 3 stock roms with diff radios (KA3, KB3, KD1))
Maybe anyone got an idea or a hint.
Sounds like ur in a weak 3g area so it keeps goin back to 2g

Granted I'm not in the best 3G area, but I usually get 3 (of 5) bars in 3G and then it just pops back to 2G.
Might be network pumping (or w/e it's exactly called), gonna exchange the sim anyway to track down the problem further.
Are u on orange in the uk

I have this problem aswell. Thing is 2 3g bars are way faster than 4 g bars. I cant change it to use only cdma in the service menu. Anyone know why.

So does change of simcard help?
I got it fixed for me. I tried n3 and n5 sim cards, no changes. Problems were caused by faulty antennas, after being fixed by the carrier problem was reduced to a minimum. Now to get rid of the so called network breathing, which is a problem of the used communication method itself aka can't be fixed. University ftl!! Simply too many smartphones

When my phone shows the H symbol for network, it works well, but when I'm not using the network (no traffic), it falls back into 3g and gets stuck on upload. Occasionally, H service will come back, but often it won't. I have found if I turn the screen off, H service is restored.
I have had this problem for months now. I have a i9020a. Currently I have CM9 April 8th nightly installed, using the i9020AUCKJ1 radio. I just got done reverting to the stock build recently released from Google (IMM76D, I think), then upgrading to CM9.
No matter what I've done, nothing has worked:
1. reverting to stock then upgrading to a custom rom (Team-Kang, CyberGR, CM9, etc);
2. trying different radios;
3. opening phone info (*#*#4636#*#*) and changing it to GSM auto PRL as well as setting the band to USA;
4. making sure the APN is correct;
5. restoring the IMEI backup;
Any ideas what the issue could be?
H is 3G. Only active while data is being actively sent/received and it is actually feasible to use in your current area. Also, are you sure it is not only the animation that gets stuck?
Is there an actual problem, though? Is something not working quite right (data, sync, notifications, etc)?
It gets stuck on UMTS:3 (just keeps trying to upload) and won't work again until I turn off the screen and then it will usually revert to HSDPA:9.

you should download taskiller.. kill all app before you use your internet, i have same problem and always solved with that way..

While taskiller certainly kills most running processes, it does nothing to help my network connection.
On a separate note, my roommate has the same phone and his maintains a steady HSDPA:9 connection without ever dropping into a UMTS:3 connection.

The normal behavior of the phone is to use HSDPA while it's in need(download/upload) , when not in use automatically goes to UMTS:3
What ROM your room mate is using ? model ? radio ? network ?

You're talking totally rubbish ... Killing apps will not enhance anything and may even slow things down by needing more CPU power to open auto apps again...
I have expereinced the same issues with my 9020a on ATT. Sent phone to Samsung twice, changed SIM cards 4 times. Updated radios, now on 4.0.4 getting about 120 kbps download speeds while my other phone (work phone), iphone4s on att, gets about 5 mbps.
Call att, they credited me my entire months bill and offered a free galaxy note with a 2 year agreement. My thought is that ma' bell is just killing any unlocked phone or there are issues related to "LTE" rollout they wont admit to that is causing a disruption with 3.5G.
Anyways to the OP, you aren't alone. I too hope someon can help!
My roommate is using the same rom, CM9 (nightly from 3/29 though), radio is i9020xxkb3, network is also AT&T with same plan.
Watching the About Phone/Status on his phone, it stays on HSDPA:9.
My returns to UMTS:3 when not in use, but when in this mode, I get no network traffic at all. I will flash upload but will never download anything. Occasionally, H service will be restored, and I will get my network connection back.

I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?
I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.
iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086
[a business account]
im currently on slim
make sure your mobile network
is set to roam
is not set to home only
Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

i go thru periods of it acting bizarre
try disabling wifi and reboot
this USUALLY fixes mine till wifi is re-enabled
and i drop the sprint connection a few times
riding around
it then fails to re-acquire the IP address.
look in your status and see if you still have an IP
when your data fails
fwiw
I never use Wi-Fi. Ever.
Happens while using both 3G and 4G.

4G is worthless here...
i dont even bother with the switch
does it do the same thing if you disable 4G?
I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

If going back to GB doesnt help, maybe it is hardware related?

In the original post, I stated that was one of the things I've done.
have you checked to see if you have an IP address
when data fails?
mine shows "unavailable" when it's wonky
and wont re-aquire till i reboot.

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...
I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.
I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps
Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it
Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:
Backup 4g Partition
REMOVED - was a bad idea.
I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?
hi has anyonr else eperiance this same issue. whenever I go to an area that has little signal or turn the wifi off and on my phone resets to 3g. I have to keep going into the apn settings and change it from EHRPD to 4GLTE and then restart my phone. I cant change any of the settings oe delete extra APN's so I posted a screenshot and im hoping someone can help me out. Thanks

Kind of cool. Mine showed the first option chosen but it hope between 3G and 4G as usual. Choosing LTE made no difference for me. I have virtually no 4g signal where I love

Airplane mode is a feature of the phone and turns off all radios. You can hold the power button and choose airplane mode or use the quick toggle in the notification window. Since it sounds like you may be in an area with weak 4G, you can also use an app called Phone Info to set it to CDMA auto (PRL) under Device Information. You can also change it back to LTE/CDMA/EvDO if you want it to switch as normal.
With the Verizon S3, is there the need to do *228 (or *22899) ? I did this every so often on my old HTC Incredible.

Doesn't work on LTE devices. A reboot essentially does the same thing. Some have recommended pulling the battery with the phone on, removing the sim card for about 30sec and then putting everything back in.
Thanks, I know what airplane mode is, wasn't sure where the APN setting was. I will look in to phone info though.

Are you guys also experiencing the "No Sim Card" and "No Network Connection" issues?
Or is this an entirely different issue?
When this phone goes to 3g, it does seem extra bad on how long it takes to switch back to 4g. i have areas where i live where it goes to 3g when going in between hill (less than a 50 foot stretch) and it will not go back to 4g for over 10 minutes if i dont manually do it. Not to mention my LTE never goes above 10 mbps on the best days
Somewhat related...If you use Anycut to create a shortcut to IOTHiddenMenu, enter the ##DATA# Menu, edit. Under "Advanced", there is an LTE toggle, under "Other" > "HDR/1X" you can set the phone mode, and then under "Other" > "LTE APN Settings" you can somewhat modify the APN settings, reset and discard. If it asks for a password, it's 000000.
I gave these a try. I'm trying to find a way for my phone to favor 4G when there's a 4G signal, no matter how weak.
Yesterday I did a test, 3G with 3 bars vs 4G with 0 to 1 and 4G had consistently faster download speeds and shorter ping times. The upload varied from similar to 3G to slower.

probably easier said than done. The phone info app can force LTE but you lose voice and text.
Ya I found that out yesterday when testing speeds. I went to send a text then make a call and no luck
Otherwise 4G service where I live could be excellent at one spot then a mile away no service. If I had excellent 4G consistently I'd consider GoSMS which I believe has the option for data text and also a separate VoIP app
Ah well hopefully something will be figured out eventually. With a strong 4G signal 4G is considerably faster and more consistent than my 20mbps home broadband

I've had similar issues with my network. I had no 4G in 4G areas, but mainly my wifi would disconnect randomly and 3G also dropped to 1X a lot. I ended up having to send it back and get another one. So far no issues. Also the new ones have an "Updated" sticker on them. I think it was just a software update they applied, but I never got the OTA on my old phone.

Your new phone came with an already updated firmware version I535VRALG1 instead of the original version I535VRALF2.

Not sure if anyone will have the same luck I have with the "Phone Info" app, but with it I was able to get my 4g service back and my phone is functioning normally again. Just open the app, select Device Information and scroll down to "Set preferred network type" and select "LTE/CDMA/EvDo" then get out of the app.. 4g should return shortly there after. When I looked at it, my device was set to "GSM/CDMA auto (PRL)"
Anybody else having this issue? LTE works fine until..it doesn't, and then even if I was getting LTE in the exact same spot, it never jumps back on it. Once it's in 3G, it stays 3G until I restart. Any way to fix this?

You are in a area where they have not fixed circuit fallback. ... they made the phone do this so you would get calls and text ... triband phones use cfbs to push through calls so if your connected to lte you will not get calls and text.

I get what you're saying, but I don't believe that's it-- I stay on 4G most of the time, but once I get a call and it shifts me back to 3G, it never moves me back to 4G after the call. It just sits on 3G until I cycle airplane mode or restart the phone.

Actually, if you read, it's not. If I wasn't in a CSFB market, then I wouldn't connect to LTE at all except for a moment, and then drop off. I do connect to LTE, and receive calls without a problem. But let's say I pick up my phone and walk into another room where the LTE signal isn't as good, and my phone drops to 3G-- when I come back to the good LTE reception room, it should reconnect, like my previous phone would. Instead, it doesn't. It has nothing to do with CSFB.

Ok well good luck getting help fixing this problem with an atittude like that. Since I've had this phone, I mostly see 3G but with my S4, I never saw 3G. I can get it to be on LTE all day long when det to LTE only. Its something to do with 3G/LTE hand off and the single band data/voice radio.

My "attitude" was simply to correct you, since you either didn't read the article or didn't understand what I'm talking about.
I can agree it's probably something to do with the hand-off and/or the radio/how aggressively it decides to change connections, but that's not CSFB.
