This is starting to bug me..... for no reason the 4g connection and even when I turn off the mobile network, wait a few minutes and turn it back on, it still wont work until I reboot the phone. Sometimes rebooting it doesn't work and I have to pull the battery.
Anyone know whats causing this? When this is happening I see the ^ arrow on the 4g connection lit up like a christmas tree but nothing is uploading and theres no data connection....... HELP!
Mine dropped Last night for the first time. When I first got the phone it flip from 3g to 4g at my job. Last night finally went dead. I rebooted and still no network. Then I used the new LTE switch to keep it @3g only. It worked.

Where do you get the LTE switch?
I have seen it step down to 3g and back up to 4g LTE but its just sometimes 4g just chokes for no reason......
Surprise u didn't hear about it. Its a free app. If it was a paid app it would sell like hot bread. Check the market. I can't post a link yet since I'm brand new to the site

same issue with mine in Denver
You also go to your dialer and type in *#*#4636#*#* to get to the menu.
same issue here Philadelphia sub
when i bought the phone, it is very easy to get 4G in my home and work
and recently, I only can get 3G in home and 1x in work.
and it is not stable, very easy to drop.
Yea sometimes 4g just hangs and it wont step down to 3g...... forcing me to reboot or hard reset .....

Hey Stoneskin,
I live in Hawaii and I have the very same issue as well. I picked up 4g easily in the "so called" extended 4g coverage region when I first got the TB. Then about the middle of last week, poof, no more 4g except for in the true 4g areas. My thought is because so many people were having 4g connectivity issues in these extended area, VZW simply stopped allowing it as a troubleshooting measure that apparently is still going on. I brought this up to VZW tech support and they were clueless as usual. I also posted in the VZW Community Forum hoping to get an answer, but none thus far.
you could try dialing ##778# and pressing send, select edit mode, password is 000000 and then under modem settings change it to rev A. then press the menu button to save and reboot. it has helped me out in the El paso area. friend showed it to me the other day Far as i can tell is that it disables the new network that allows voice and data at the same time since that's the only difference i have noticed other than not loosing my connection anymore. I just a heads up this does not work on the latest version of virus rom RC1B3 sensless but did with previous version and several other roms i had tried

Thanks for the tip, but it didn't work. VZW must have changed something to where extended coverage area no longer get 4g. Only those in true 4g areas. I really think this has a lot to do with the folks experiencing the constant drop 4g issues. They must have rationalized that if the extended area for 4g is not up to par and forcing 3g would be better. Only way I can explain it. From consistent 4g to only 3g. I sure miss the speeds.
Used to be able to set mobile network to Wcdma only. Can't seem to do the same on my HOX. Need to turn off edge. Any ideas?

Network mode is locked for AT&T. No way on a stock phone to change it. Some of the devs have messed around with a toggle on their custom ROMs, but I think there were some bugs with this. Don't think any of them currently have it fully working.
Thanks. That's what I thought, just wanted to make sure I didn't miss something.
Strange how ATT wants us off of edge, but they don't give us the ability to turn it off if we don't need it. For me it switches to edge frequently and then back because of poor service in the area of my house. On my inspire I just turned off edge, problem solved.
Why does ATT just not get it?

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.

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

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?
I'm on the stock ICS. Is it possible to disable LTE, because I am not in an LTE area. And I would like to have everything my battery has to offer.

You don't need to change anything. Your battery will only draw more when actually using lte. For example, I get much longer battery life at home (no lte) with a lot more use then I do on days when I work and am in an lte area with little use.

I believe there is a way to turn off lte (personally I don't know how). Data is always on (unless u manually override it) and it picks up the signal. If it picks up data from lte then it shows as lte and if not then it stays at 4g. Sorry, I know I worded this poorly and it is confusing as a result. I feel lte isnt constantly searched for but rather goes through the data (which is constantly searched for). It simply notes whether the data as delivered via lte or 4g. Again, sorry for the rambling post and note that this isn't fact but merely my opinion. If anyone knows for sure, please chime in

There are two radios in the SR, one for GSM/UMTS/EDGE/HSPA and one for LTE. LTE is data only, all voice calls still go over the GSM radio.
The phone prefers LTE for data, so if you're in an area of weak or no LTE service then it searches for LTE periodically. The worst case is areas of weak LTE as the phone will hunt back and forth between GSM and LTE radios.
LTE cannot be disabled in the stock ICS rom.
CM9 has a Network Mode option to select between GSM or GSM/LTE. I switch to GSM only while at home as the LTE signal is marginal there.
You can disable lte thru the build.prop... but don't do it unless you know what you are doing... i have a set of bad ass tweaks that will do this for you and will be posting in the dev section as soon as i get all the bugs worked out

Wouldnt running a RAT unlocked radio keep it from searching for LTE? I run the UXLF3 on mohans stock/deodexed UCLF6 and dialed *#2263# and changed to WCDMA ALL. My way of thinking was even if LTE was on, the phone wasnt searching for it. Right/wrong?
In a different thread about turning off LTE radio, someone was saying that you cannot turn off the radio itself. You can still turn off the LTE mode (which I presume only tells Android not to try to use the LTE radio) if you have a RAT-unlocked radio (e.g. UXCLF3 from Seanz' Sky ICS thread).
I'm using Seanzscream's Sky ICS ROM and in the latest version (4.2F-7B) you can switch off LTE from the Mobile Networks -> Network Mode menu instead of going through the *#2263# Service menu.

Actually mine doesn't work. I saw the option for it so I flashed the uxlf3 and it still doesn't work. Whatever I select holds for a couple seconds and then defaults back to the auto setting. (GSM/HSPA/LTE auto)
That is correct. You CANNOT disable LTE Radio (you can change the preferred network mode).
- You need to be first SIM Unlocked and have a RAT Unlcoked Radio.
- And, you need a ROM with that feature enabled. My EMBRYO ROMS have always supported this (I need it too ).
Will turning off the LTE also disable the 4G? We do not have LTE here in podunk SC. I am running TC JB 4.1.1 with InstigatorX 6.3.4. Would love to keep the 4G but desperate to find a battery fix that works.
I think cm 10 allows you to toggle networks to get 3g not for certain though
I know embryo 5.1 allows network change with requirements

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.

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)"
