Having this problem as well. The signal bars and 3G icon will be green, but I won't receive push notifications like gmail. Once I start using the data like opening the browser, the bars will turn gray. After a few seconds of waiting the page will finally load, and then the bars will turn green again. Once the bars turn green, my new emails start to flood in. It's like the phone can't maintain the connection when the screen is off!

Ugh... knew I should've stayed with the MT4G lol.
[Nexus S General] justsignbythex:
I'm having a loss of data after phone calls (both received/dialed calls).

I go to hang up my phone by pressing the end key on the screen, and I notice that the 3G icon on top is completely gone. Bars are gray and there is no signal.

I still live in a developing T-Mobile 3G area, and regularly, I would have about 1-2 bars on 3G.

Last night, I made 2 test calls and hung up. First time, the situation above happened. Second time, it wasn't as bad. I would still have full EDGE coverage (green E on the top), but it would take about 5 minutes to receive 3G coverage.
[Nexus S General] savante:
wifi data stopping too?

Anyone else have this sudden data loss with wifi as well?

It's happened to me a few times.

It always seems like I notice loss of data (3g or wifi) after bringing my phone out of sleep.

I wasn't sure what was supposed to be happening when the phone wakes up but with all the issues people are seeing with data, I started thinking maybe it was TCP/IP stack related. So I created a shortcut to the testing menu to try and troubleshoot this issue the next time it occurred.

Today, I pulled my phone out and the wifi signal was strong and as you can see it was connected with full grey bars but I couldnt get any data. However my internet was working fine on other devices/computer.

I then went to the testing menu to try and run the ping test. As you can see, it failed with an I/O exception. Refreshing stats and re-running the ping test had no effect. The only thing that fixed this was powering off wifi and powering it back on.

Just curious if this could be related to the sudden data loss we are all seeing with 3G as well or if this is a completely separate issue...?
[Nexus S General] Teknojunkee:
Loss of Data Fixed for me

I have had the same problem with my Nexus S. I lost data two days after purchasing and registering the phone.

I came across a forum stating that changing your data plan to the "4G" Data plan fixed the problem.

I have a grandfathered plan so was still using web2go which apparently is not compatible with the Nexus S.

After speaking to customer service and adding the "4G" data plan my data service was restored after 25 mins.

The new data plan is the same price.

Hope this helps.
[Nexus S General] wootek76:
Im on 4G data plan as well but still have an issue. Im thinking that it has to be one of the application or launcher. I wyped my phone to factory so i have to wait and see if it happens again. This is my third phone so it cant be the hardware issue.
[Nexus S General] SpookyTunes:
I stopped having the Cell and 3G disconnects after I enabled "Data roaming" in "Mobile network settings". AT&T is the only other network in my area, so I don't think I am on their network. My SIMM is from 2003 also.

As for WiFi issues, I disabled "N" on my router when I realized one of my 3 "G" laptops was the cause. I only got 65 MB/s on "N" so 54 MB/s is not an issue.
[Nexus S General] intothevoid:
Since changing to a new SIM card and requesting T-mobile for data tower reset the issue seems to have gone away. Hopefully it stays that way.
[Nexus S General] Trinitronik:
Sudden loss of mobile network on Nexus S

If you have this problem, please type here.

here is a video made by me about that trouble:

http://www.youtube.com/watch?v=JVykeBEkifc

So what do you think?

The only way to fix it is REBOOTING... It happends 2-3 time per day...
[Nexus S General] distortedloop:
Isn't there already a thread on this?

Anyways, this happened to me for the very first time yesterday.

Somewhere between talking on the phone in my car, going into the house, finishing the call, then going back out in my car, by the time I arrived at my destination 3 miles away, I had the same no service issue you're demonstrating.

Airplane mode, switch on/off data, roaming, 2G-only, try to select network, nothing worked to get it back.

I did run a logcat, but nothing in it to suggest the problem.

I finally had to reboot to get signal back. Interestingly, and perhaps related or not, I was only getting "G" (for gprs) on the data side inside the building I went into after rebooting. I normally get weak 3G or strong EDGE inside there.
[Nexus S General] simms22:
gprs is what you were getting
[Nexus S General] distortedloop:
Yes, that's what I meant. I knew that, just had a senior moment...seem to be having more and more of them these days. :D
[Nexus S General] simms22:
now with this, my friend, i know exactly how you feel ;)
[Nexus S General] AllGamer:
yes there was, now they are merged
[Nexus S General] Trinitronik:
It drops again and again! I'm getting really angry about that!

Installed Nightly cyanogen, but still drop signal!!!
[Nexus S General] johoja:
Summary of baseband bugs in Nexus s

1) Having network selection set to manual ( i.e selecting 302490) will result in No Service on a reboot.

Solutions:

- Have to cycle airplane mode to get it to pick up service (can be done with automatically tasker)

- OR Use automatic network selection. (you can force wcdma only but that will reset the SMSC which is annoying if you go in and out of wind away/home areas and you want to roam.)

2) Being in a area with no service for extended periods of time 5+minutes(subway, basement, etc) will result in a dead baseband, meaning once you come into an area with service the phone will not reacquire signal, airplane mode will not work as the baseband is now crashed, cant maunally search for a network. Have to reboot to get signal.

Solutions:

-Use tasker to cycle airplane mode on and off when in no service areas i.e) search signal 4 minutes, airplane mode on 10 minutes. This will keep the baseband from crashing and possibly save battery.

-Use NoBars to accomplish the same thing ( tasker gives you a bit more flexibilty of course but harder to use) http://www.appbrain.com/app/nobars-battery-saver/com.tomdryer.nobars

- Use airplane edit to avoid turning wifi/bt off when airplane mode is on. http://www.appbrain.com/app/airplane-edit/net.cenkalti.airplane

3) WCDMA perferred does not work.

- No solution.

These are all software bugs/baseband so hopefully they will be resolved soon by google. Voice your concern on the google mobile forum though. These are reproducible on stock, and any ROM.

http://www.google.com/support/forum/p/Google+Mobile/thread?tid=747f398a6c1bb2b9&hl=en&start=40
[Nexus S General] fchipm:
Sad - I think this issue is just as annoying and frustrating as the "Reboot during calls" bug, yet that one seems to get all the attention.

This bug is SERIOUSLY, SERIOUSLY bad. I lose data twice a day (or more) and toggling airplane mode doesn't work. I don't know i've missed ten calls and texts until I decide to turn on the screen an hour later.

Has google acknowledged this issue yet?
[Nexus S General] johoja:
No Sir!

Try installing NoBars.
[Nexus S General] raeef:
I don't think this is related to T mobile or 3G. I am in Jordan connected via EDGE. I lose data connection and it doesn't come back , it comes back suddenly just as it disappears. It happened twice today. Is there a bug report on Google's support site?
[Nexus S General] fchipm:
Thanks for the tip man. Installed it and still am losing data. Maybe its not set up right.
[Nexus S General] hardstyle123:
Mine acts weird.

If I'm on a call it disconnects and it still shows full signal but cannot make a phone call again. I have to reboot in order to use the phone.

Sucks
[Nexus S General] Essenar:
I'm having data issues on my MyTouch 4G that seem very similar to you guys.

I had a MyTouch 4G and the first day, data was amazing. 4G solid connection 3MBPS minimum. The next day the connection started deteriorating and I experienced trouble getting it going after going in no signal area. I would drop to Edge, get back on 4G and it was fine. But after a third drop to Edge, HSDPA wouldn't work any more. It would show the icon like I'm connected but I would not get any data at all.

Have you guys tried switching to GSM only to see if the phone works? If switching to GSM only fixes your calling issue, then you're experiencing almost the exact same problem as me.
[Nexus S General] distortedloop:
That's actually disturbing to read! If the MT4G on 2.2 is having the same problems, then that means it's a T-Mobile issue, not a Nexus S/Gingerbread issue like many of us assumed.

I trust Google to fix things faster than TMo....
[Nexus S General] Essenar:
I'm not sure it's a TMobile issue either.

Not all MT4G's have this issue. I'm definitely not the only one though as others have reported the issue in the exact same experience.

The other thing is people not even on TMobile are also having this problem.

Plus I have no issues with wifi, making calls or edge.

Here's my understanding:

Both the nexus and the MT4G use a combination WCDMA/GSM antenna for data and cell usage. When my phone drops to edge, it can't connect back to 4g. When I switch to GSM, I get edge data no problem but it appears as though my WCDMA baseband is dead.

The other difference is restarting my phone doesn't consistently get me back on 4g.
[Nexus S General] Essenar:
I was going to exchange my MT4G for a nexus s, but they were sold out. I was hoping the replacement wouldn't have these connection issues but I was wrong. It worked fine but deteriorated over a day.

It looks like the Nexus S isn't without issues too.

I don't believe in coincidences. Maybe its either an issue with the WCDMA/GSM switch in some newer devices causing complete failure of the baseband. But with the Nexus S restart fixes the problem whereas other phones just come back on their own.
[Nexus S General] distortedloop:
Aren't Vibrant and i9000 also wcdma/gsm phones? No problem on either of those that I've used.

Who knows what the issue is, but it's getting worse on my phone, from never having it in the early days to a couple of times per day on some of the days in the last week.
[Nexus S General] gogol:
I think, we should give up on this issue ... and accept it :(

Because if I remember correctly, there was (is) similar issue with Nexus One and Google just gave up:

http://www.gadgetell.com/tech/comment/google-gives-up-investigation-on-nexus-one-3g/
[Nexus S General] distortedloop:
Wow, I forgot about that, but I never experienced the problem on my Nexus One.

They basically gave the Steve Jobs "you're holding it wrong" answer before Jobs did and became heavily mocked for it.

I don't think this is the same issue. I can have plenty of signal strength, but the bars still turn white and I lose data services, despite 5 bars and 3g icon showing. Wasn't the N1 problem was that people couldn't get a signal (ie, no bars) while on 3g.

Also, that incident shows that the N1 and HTC wasn't perfect like many around here who criticize Samsung seem to recall the early N1 days.
[Nexus S General] meetagrawal:
Well, that is quite comforting.
[Nexus S General] LionAR10:
I have this problem on my SNS (Simple Mobile $60 unlim) .. but I also had it on my Vibrant (Same SIM). But it wasn't limited to just TMo US (SM is MVNO) ... I had the problem on my Vibrant in the UK (I was on TMo UK Prepaid) a few weeks back.

I'm currently trying the NoBars solution, I just installed it so I don't know if it works yet.
[Nexus S General] johoja:
Vibrant had similar issues with baseband dying I believe I've posted about it here with links to threads with similar issues. Vibrant has the same chipset for AWS/GSM as Nexus S.
[Nexus S General] johoja:
Let us know how it goes...it works for me i.e) baseband doesn't die. Don't need to reboot to reacquire signal.
[Nexus S General] Trinitronik:
Guys!! Twitter them! @SamsungService

It must help! Google always know about that problem, and there is no any info from them... Crossing fingers that next OTA update will help us to solve that trouble...
[Nexus S General] Trinitronik:
What settings do U Use?
[Nexus S General] distortedloop:
Thanks, my time with a Vibrant was limited, but I gave it to a friend and he never complains of this kind of issue. He's using it soft-unlocked on AT&T though; no AWS there.
[Nexus S General] johoja:
Search singal timeout: 2 minutes

Airplane mode timeout: 10 minutes
[Nexus S General] johoja:
Tweet this : @GalaxySsupport @Samsungservice @googlenexus hey lots of issues with Nexus S and baseband dying! http://bit.ly/hqhgpv
[Nexus S General] distortedloop:
I've tweeted @GalaxySsupport...they claim to be official support for Nexus S as well.

The reply to almost every issue is a standard "We've escalated the problem to Google, but I don't know when a fix will come. ^Mary"

Still, the more tweets the better, right? They won't like all the negative hits on their image.
[Nexus S General] Essenar:
Still no resolution on this?

So I have to choose between a MyTouch 4G that drops 4G and requires a restart, or a Nexus S that drops its entire baseband and requires a restart?

Wow decisions decisions.

Who's a better boyfriend for me, Chris Brown or Ike Turner? HMMM.
[Nexus S General] johoja:
tweet galaxyssupport make noise
[Nexus S General] Ulver:
I've been having an issue like this as well. My 3g and status will be green but my up arrow will stay lit for the longest time and nothing would load. After awhile ill either get a connection failed and have to reload it and it will finally work. I also have encountered the bars going grey for no reason.

I contacted T-Mobile and had them activate the sim card that came with my phone as my old one was about 9 years old. That didn't seem to remedy the issue so I called them again and had them reset my phone on the network. So far its been pretty good. Its so weird that this issue just happened out of nowhere. For some reason it all started after I got a Google voice number on my phone, but I highly doubt that caused the issue, its probably just coincidental.
[Nexus S General] KUKitch:
Bump - This is the exact problem I have, and it is pretty frustrating though I feel as though I've had the issue with my N1 and Vibrant in the past as well
[Nexus S General] Ulver:
I still occasionally get this problem. Its so frustrating. Another thing that happens is after a brief extensive use of data over 3g (either a few MB app update or using my phone as a hotspot for a couple minutes) my data will just stop working. I still have full green bars. I have to switch my phone in and out of airplane mode to get a connection established. I'm hoping 2.3.3 fixes this issue.
[Nexus S General] meetagrawal:
Does Pandora have any issues for you guys? It will play one or two songs, but then it gets caught up the "Loading" thing for me. I was wondering if this is due to the data loss problem, or whether it's an issue with the Pandora app.
[Nexus S General] Ulver:
I haven't tried Pandora yet but I will. It sounds like you're having the data loss issue. Hopefully someone else chimes in.
[Nexus S General] Ulver:
Just started using Pandora and I'm having the same issue as you. I'm able to listen to a few songs, then I'll get caught up right after the song and it will get stuck at "loading." I'll try my browser, tapatalk, facebook, etc and nothing is loading for me, yet I'm green full 3g bars and the arrows are showing that data is up/downloading. I have to put my phone in and out of airplane to establish a data connection. Once it's back, the next song on Pandora starts up and all my data is working again....for now.
[Nexus S General] fchipm:
Does NoBars actually work for anyone to fix this?

I've got my settings the same as everyone else and the only thing it does is notify me that I've lost signal. Handy, yes, because I have NoLED set to alert me that I've lost signal. But it doesn't actually fix the problem.

It tells me that I've lost signal and has put the phone in Airplane mode per my settings. But when I try to back out of airplane mode I can't, and still have to restart my phone.
[Nexus S General] Ulver:
Anyone having problems after 2.3.3 update?
[Nexus S General] SupaDupaFly24:
Nope no problems with this issue yet since 2.3.3 update!! *knock on wood*
[Nexus S General] Xidroid:
Yes. It's not as bad as it was on 2.3.2 but it's still happening.
[Nexus S General] carlost24:
Is there a solution for this? i have all my bars an instead of the 3G i have a lil notepad with a exclamation in the middle, pull down notification bar says "emergency calls only", i need to fix this asap i have interview in about 2 hours so any help will be greatly appreciated....

* im on 2.3.2 completely stock*
[Nexus S General] johoja:
Goto 2.3.3. It's a lot better on that.
[Nexus S General] carlost24:
Nevermind just got a new sim card and that seem to fix it...
[Nexus S General] Xidroid:
I did too and it eventually started crashing again. After upgrading to the 2.3.3 radio it worked great for a while. It seems like the longer it goes after a "fix" the worse it gets.
[Nexus S General] justsignbythex:
Bump.

I've had this issue on my Nexus S (AT&T/Rogers) for the past 4-5 months. I lose 3G frequently and I usually have to either toggle airplane mode on/off or reboot. Sometimes I can't even toggle it because the baseband has crashed.

It only happens at home, which leads me to think that one of the towers around my house is acting funny. I'm seriously considering a new phone (or switching back to my old Nexus 1).
[Nexus S General] MrSmileyJr:
Still got this issue on Straighttalk in NJ. I'm using Jellybean with the latest radio on 9020a. :-/
[Nexus S General] jitzbox:
Same here.

Infact, after the data disconnection, even if i come to area where there is a good signal, data doesn't connect. The only solution is to restart.
[Nexus S General] greg2826:
Same here lads, always had problem with loosing internet connection on my Ns, it's turning grey and sometimes toggles r enough to fix it and sometimes i need to airplane or reboot.

It's happening mostly when I'm at home.

Not sure if this is this particulary phone problem, since i had few Android phones and always had such a problems.either phones, crappy network signal or both.
[Nexus S General] MrSmileyJr:
which phones did you have greg? all samsung?
[Nexus S General] greg2826:
lg, zte, htc, samsung.
[Vibrant Q&A, Help & Troubleshooting] ZX3ZX4:
I haven't done this because my GPS has gotten pretty good after JI6. I've read that all this app does is put the LbsTestMode settings back to factory, and I know what those were, and what I have now, so I could change back if I didn't like the result. But I'm curious if anyone knows if it does anything else that is not visible or reversible.
[Vibrant Q&A, Help & Troubleshooting] explodingboy70:
Does nothing else but restore settings and test.
[Vibrant Q&A, Help & Troubleshooting] ZX3ZX4:
Thanks. Two other related things:

1. Do you think it also clears GPS data?

2. Shouldn't JI6 have done the reset to factory GPS settings if one of its purposes was to fix the GPS?
[Vibrant Q&A, Help & Troubleshooting] explodingboy70:
Seems like it should clear data but doesn't explicitly say that it does. Probably not. I think ji6 may have changed the modem and how it interacts with the gps. If you are wanting to find out what you should see you can google vibrant gps settings or fix and there is info out there. Also look around here as there are several threads.
[G Tablet General] Frozen001:
Anyone else see this... Brute forced incrementing the number from Roebeet's prior post and found this:

http://tapntap.http.internapcdn.net/tapntap/update-smb_a1002-3338-user.zip

98.4MB

Don't have tablet at work so can't try it...
[G Tablet General] cotily03:
downloading it now...

will see and let ya know...
[G Tablet General] brian_h_kim:
some quick observations (from 3316):

tablet now defaults to stock android launcher (Home)

TnT is now the "Dashboard"
[G Tablet General] roebeet:
They touched some of the apks, and most of the framework FYI.
[G Tablet General] cotily03:
Pretty cool so far...

After updating to this firmware, it is the first time I have ever got the welcome screen to setup my device.

Anyways a few thoughts:

On the quick launch bar on the right there is now the standard web, mail, apps, settings, but there is also a dashboard button that brings you to the old TNT homescreen (which I actually liked).

my quadrant scores are averaging around 1900.

I tried to figure out how to do screenshots but no luck...
[G Tablet General] zerozed99:
I'm glad to see that Viewsonic/TnT are moving more rapidly now with their support for the device. Their reputation is on the line; Staples really slapped them in the face, and Engadget did their best to really malign them.

Their recent releases along with their acknowledgement of the work done by the XDA devs will really build up their credibility with early adopters. I hope they follow through soon with source and continue to engage us in these forums.

If Viewsonic stays on the ball, I'll definitely consider purchasing their next tablet as long as it comes out with a 10"+ screen (hopefully a bit better quality).
[G Tablet General] tmellen:
Having messed with all of the available ROMs for the G Tab, I like this and will play with it for a while. It's "official" and it gets the TnT out of the way. Also, same for me, this is the first time any of the official ROMs let me go through the setup for the tab.

I am missing the back and menu buttons on the status bar though. I wonder why they got rid of those. They were VERY helpful when using the machine at night.

Now, time to titanium restore my apps!

Edit: Just discovered it killed Clockwork. A minor annoyance, but annoying none-the-less.
[G Tablet General] Sprdtyf350:
I learned something from Rothnic today that will help... Clockwork will still be there.

Open update.zip

Find updater-script, Open in notepad++

Remove the line that references recovery.img

Flash update
[G Tablet General] brian_h_kim:
or you can just reinstall CWM via stock recovery (e.g., from external microsd card)...

then install the Tegra GAPPS via CWM and then do the Market fix and you should be set...
[G Tablet General] rothnic:
For anyone installing an update like this, it will include their stock recovery. You can easily remove it before flashing, however.

Open the update zip

Open the updater-script a couple levels down in Notepad++ or other linux compatible editer

Remove the line that references the recovery.img

Save

Flash
[G Tablet General] tmellen:
Yeah, thanks for the info... I jumped the gun! :) I just reloaded CW from SDCard, Z4'd, Titanium backup'd, all set now! -Oh yeah, I need the tegra googs.

I love Android! The ability to do all this, measured in minutes, not hours or days, is so freaking awesome.
[G Tablet General] manfly9884:
So it will look like this now?

ui_print("Installing Tap 'n Tap build 3338");

show_progress(0.100000, 5);

assert(package_extract_file("bootloader.bin", "/tmp/bootloader.bin"), write_bootloader_image("/tmp/bootloader.bin", "bootloader"), delete("/cache/bootloader.bin"));

assert(package_extract_file("boot.img", "/tmp/boot.img"), write_raw_image("/tmp/boot.img", "boot"), delete("/tmp/boot.img"));

show_progress(0.800000, 30);

assert(package_extract_file("system.img", "/tmp/system.img"), write_yaffs2_image("/tmp/system.img", "system"), delete("/tmp/system.img"));

show_progress(0.100000, 1);

Thanks in advance
[G Tablet General] Turbo4V:
That's correct!
[G Tablet General] Frozen001:
Well I installed this ROM and this is the best I have see from TnT and Viewsonic. So far no problems.
[G Tablet General] tmellen:
A new problem...

I can't find a tegra gapps package that works without causing Google framework force closes over and over.

Anyone have a link?
