Hey guys,
This is actually my first post here but I do A LOT of reading on this forum.
I didn't quite find anything regarding my question (or at least a solid answer), however, so I've decided to post it up.
Has anyone else experienced a sudden loss of data from time to time out of nowhere?
I go from having Full Green 3G bars to grey bars out of the blue. I've heard the green bars is to let you know that you are connected to Google services but I am not able to access anything that uses data.
For instance, when I open up the browser, I receive an error telling me there is no network connection. When I open up anything else that uses a data connection, Market, News, etc, I receive the same error about there not being a connection.
This would make sense if I was moving and going in and out of service areas, but it happens when the phone is simply sitting on my desk and not moving at all. I usually use it to listen to Pandora while at work and have noticed that the songs cut in and out due to this sudden loss of a data connection.
I went from a Nexus One to the Nexus S and have never, not once, lost my full 3G bars in this same exact location. I personally believe its a software bug of some kind and have high hopes for it being fixed in the future. The N1 had similar issues when it first launched and Google / T-Mo were able to remedy that for the most part.
I am actually on my third Nexus S because the first two had some type of hardware issue; the first one's back button didn't work or light up and the second one had a blown ear speaker and would sound like a blown speaker in a car. As an early adopter, I expected this, so it didn't bother me in the least bit.
ALL of them did the same thing, so I know it is not just limited to my exact phone. This is definitely something with the Nexus S in general (or the current build of Gingerbread).
Can anyone shine some light on this situation? Thanks in advance and keep up the great work here guys!
---------------------------------------------------------------
UPDATE: Here are a few steps that I have taken in order to solve my sudden loss of data issue. I'm not guaranteeing this will work for you, but it has worked for me and a couple of users here on the forum.
Do the following:
Activate / Use the Sim Card that came with the phone (this is to ensure you are using the latest sim cards)
Make sure you have a 4G internet plan. (No t-zones, No web2go -- FULL internet only)
Call T-Mobile and have ask them to Reset your phone with their Towers
Here's a more technical explanation posted by Johoja:
1) Having network selection set to manual ( i.e selecting 302490 or TMOBILE) 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 thesamething ( taskergivesyou a bitmore flexibilty of course but harder to use) http://www.appbrain.com/app/nobars-b...omdryer.nobars - Use airplane edit to avoid turning wifi/bt off when airplane mode is on. http://www.appbrain.com/app/airplane...kalti.airplane
3) WCDMA perferred does not work. - No solution
http://www.google.com/support/forum/p/Google+Mobile/thread?tid=747f398a6c1bb2b9&hl=en&start=40:
I read one users response on a different thread regarding something similar to the issue that I am having.
They said T-Mobile told them to get a newer sim card and that this may remedy the problem. In my case, this has been the only constant in the 3 phones that I have been through. I have had the same sim card for about 3 years or so now.
I will try activating the sim card that came in the box with T-Mo to see if this remedies the problem. Since I'm at work right now I will have to try when I get home later.
Does anyone think this will have any affect what-so-ever?
The galaxy s phones when first released, all variants, had issues of signal dropping from full to zero bars while sitting in one place. I remember because there were YouTube videos of it All over and it was shortly after the apple antenna issue.
Not sure if or how it was ever resolved. But it seems that Samsung may just have this type of radio baseband performance if we see all these individual units doing this. I don't know maybe others can respond.
I have the same issue as the OP. I travel to the same location weekly with NEXUS ONE, signal never drops in the T-MO Country here locally, and streaming CNET POD CAST never a hiccup, however, with the new NEXUS S, I would lose DATA Connection only, while the 3G will show full signal. I had to reboot the phone to get the DATA back.
is it the S issue or 2.3 issue?
food for though....
If you have T-zones or Web2go or Phones 1st web, you will have problems
I had the same problem too, now I fixed the problem. The thing was that had the wrong data plan on the NS, i had my old web plan from my hd2 which seems like different from the one for the NS. I restarted my phone after 5 mins off and now i have my internet working beautifly. A T-Mobile rep said that it was an error in the system that made the phone think that that was the right plan for the NS for a few. A glitch you may say, but all you have to do is put the right data plan that all, easy. Hope this helped and have a wonderful holidays everyone.

this is happening to me too, last night for a little while and today for about hte last 4 hours can't get connection back. i have full white bars, with 3g icon but can't access anything
So I activated the new sim card last night and I'm still having the same problem. Albeit it doesn't happen as frequent, but it still does it nonetheless.
I will call T-mo again to verify my plan. I am on a 1500 Minute Family Plan which includes unlimited data and messages. I will see if they need to tweak something and let you guys know if this remedies the problem.
Ok, it seems like the issue has been resolved after I spoke to T-Mobile earlier today.
The rep on the phone verified that the data plan I was on was in fact the correct one. He said he was going to reset the signal from the towers to my phone to see if this would resolve the issue. He asked me to turn my phone off for about 15 seconds after we hung up.
Since then, I haven't seen the problem arise again so my guess is that it somehow fixed whatever was going on.
I'll let you guys know if this changes and the problem occurs again.

What's with the CAPS? ?
On topic: i have a captivate and I can confirm that all galaxy S phones had droppend data. An official ota update fixes it so maybe you guys need to wait for something official. Isn't there a new firmware for the nexus S already? Try flashing that and see if you still have issues.

Doesn't every android phone from samsung have this problem?
I know the Moment has that problem, after 3 updates samsung called it quits, I still have to reboot mine 2 to 3 times a day for data lockups.
@timur525 Yea, I'm already on 2.3.1.
I manually updated the first hour it came out hoping that it would solve the issue. The problem was still there after the update.

I have exactly the same issue as the OP. Extremely annoying to reboot the phone every time it happens. One thing I have noticed is that my phone doesn't know its number. If I go to settings, about phone, the number says unknown.

That shouldn't affect anything. My number shows up in status.
I had this issue resolved a few months ago as the push-to-talk app Tikl requires this in order to use it.
I was having the problem even with my number showing up. Call T-Mobile and have them reset you with the towers like they did for me and see if that helps you too.

I posted about this same issue on wrong section of the forum. Ive had this issue ever since samsung vibrant. I have applanet installed on my phone and some of the app that i installed accessed my apn and totally changed my apn setting to "Sirious application disabled.epc.tmobile" or something like that so i wyped everthing off from the phone and so far i havent had the issue ever since yesterday. Also i had the locale and language setting to korean so im thinking that might be causing it also.

That's what I remember too. I think its just an issue with the radio Samsung uses in all their phones. Might not be a way to fix it if even their new phones like the nexus s still have this issue. They prob would have tweakdd it by now if they could.
Same problem here. Xmas eve on shift and I have a phone that had no connection whatsoever (not even phone capabilities) this may be the one thing that takes the phone back. (If it happens again)

Have you called T-Mobile to see if they can give you a reset to the towers?
I had this done yesterday afternoon and haven't had the problem again since.
Also, if you'really using an old sim, I would suggest activating the one the phone came with just to be on the safe side.
If that doesn't help you then I would at least wait until just before your return period ends to see if there will be an update to address the issue.

That just happened to me today also. It switched from "H" to "E", then when I opened USA Today it FC-ed and the icon turned into a generic Android one like the app was on the SD card and unavailable (even though it's installed to phone) and then 5 more background apps that I didn't even know were running FC-ed (Amazon MP3, Finance, QuickOffice, something and then Facebook three times?) and the phone locked up. I was able to power off then back on, but data never came back even after waiting about 10 minutes until I powered off and on again. Quite odd.
I get the same issue where am connected to wifi and as soon as i walk away from it it doesnt connect back to the data network. I got a replacement phone coming so hopefully i dont have the same issue. Another thing is the random reboot and i get black screen a lot especially after rebooting
Sent from my T-Mobile G2 using XDA App
I've had the issue, but each time it appears to be related to JuiceDefender not properly enabling the radio. If I shut JuiceDefender off, the connection comes back, although sometimes its just easier to airplane mode it and be done with it.
I called T-Mo about it, they said call about a week after the inital release date and see if they have a fix by then, there isnt enough information kept since it hasnt been officially released yet.
I'm having the same trouble. Are you guys on the new sim card? I popped in the new sim card and the tech told me to not use it and just save it. I noticed when I put the new sim card a notification of a new voicemail came on. I didn't have any voicemail.
Edit: I'm starting to have some serious data issues. I'll get cut off, but my phone will still show full bars and "H". I try the whole airplane thing and it still does nothing. I constantly get the "check network setting, try again or cancel". My market wont load, browser says "unable to connect." This is getting stupid. When I call T Mobile it always start working and then cuts off shorty after hanging up. I've never had this isssue before. I live in the middle of the city. Only 3G around here. Its getting annoying.
Guys I'm afraid that it might problem with the antenna placement. Holding the phone on the bottom half will drop me from 3 bars of "H" to 4 bars of "G", then it will bounce back up to 4 bars of "E". If left on a desk then it will remain at 3-4 bars of "H". I notice this especially at a place where I have low-mid signal, such as my school (reinforced concrete FTL). When I have a strong 4 bar signal, it usually won't drop all the way down to edge but I do loose a few bars. I hope a simple software issue is enough to reduce this effect. I might be being crazy paranoid but I'm definitely noticing a lower signal than on my G1.
Try holding the phone by the edges, then hold it in a normal grip and see if the signal strenght changes (Menu->settings->status->signal strength)
I just got off the phone with tmo and was told its a known issue with the network affecting about 10% of users. The issue started for me yesterday on my hd2. He also said they have people working on it. I asked if I could get my buyers remorse set back 14 more days to ensure the issue is not permanment but he said that they are no longer doing extentions. I'm sure if I get tranfered to retentions the answer would change. I hope.

I'm also having the same issue. I just rebooted my phone, so I haven't had the chance of switching airplane mode on/off yet. I'll let you guys know if that works for me, either way, I'm hoping there's a fix from T-Mo.

Wow that's funny, my MYTOUCH does the same thing with airplane mode off/on. I also remember that the store demo g2 I played with last night had the voicemail icon in the notification bar, but when you pull the bar down, there's no option to connect and retrieve the voicemail. I found that even weirder since the phone comes preloaded with google voice.
Also experiencing the same issue here in Phoenix. Been having it since I got the phone on Monday.
I have been in an ongoing round of tech calls and will be having a follow-up with the tech who I spoke with last night... I've tried everything from APN resetting to swapping the SIM card to a total factory wipe -- nothing is changing this for me.
I *know* my neighborhood has full 3G access, but I am maxed out at 1 Mbps. (Before the factory wipe I was getting 0.35 Mbps.) If this doesn't change I may just return the phone and switch to Sprint to get the Epic 4G. I mean, I'm not getting HSPA+ coverage either way, and at least with the Samsung Galaxy S Pro I'd have a full 5-row qwerty...
>_<
Wow, this is really too bad. I was SO excited about this phone...

If this happens, try going to settings->wireless->mobile network->network operators and see if you get an "Error while searching for networks" error as I did.
Reset fixed for me too. But it makes me worry.
I'm on a brand new sim card (switched to TM from ATT). I'm having some data issues too. I talked to TM tech support and they reset my connection but that did nothing. Now they're going to their android techs to see whats up.
Got my phone two weeks ago and I'm getting a problem with my search button. it keeps going off by itself like some one is pressing them and the speak now screen come up.
Any one else here having the same issue? Theres people in the internet also having the same problem but so far no answers.

I have this problem too but it only seems to happen intermittently when I am in an area with a poor signal (1 or less bars).
I've also taken to restarting my phone every day or two and It hasn't happened in awhile.
I had this problem with mine and when I looked it up it seemed I wasn't the only one. Most people seemed to think it was a hardware issue. I exchanged my nexus for a new one and the problem is gone so I guess it was hardware.

I got fed up so I called in for a new one sent to me. I hope this one is problem free!
It happens randomly but yes it seems to happen more when the signal is low.
I may have found the problem but not a solution. I noticed when playing with the phone that its always in Roaming mode. If you go to:
Settings>Wireless & Networks Settings>Mobile networks>
you will see that the "Data Roaming" feature is ENABLED which I believe has to be on since the phone is unlocked and you wont get data service if that is not enabled(for me anyway). Try Disabling this feature and just connect with a Wi-fI and play around with the phone. See if the issue still occurs. Mine stopped with this feature disabled and only comes back when it is enabled. The phone however is useless if this feature is not enabled if I'm not around any wi-fi.
Let me know if I'm right. Maybe someone good can create some sort of fix. looks like a software/program issue?
Having the same problem with my Droid X. Seems to be a software issue that is affecting Nexus S phones in Canada most severely, but also Droid X phones in the USA.
I'd include the link to the Google support forum thread but I'm too new of a user...

Its not tied to roaming but to 3G. In your case turning roaming off turns of 3G.

Had the problem last year on stock gingerbread with radio KB3, seemed to go away when fiddling with radio settings.
Have it again this year with ICS. Using radio KB3.
Notice when travelling in/out coverage zones. (Right at the edge, when coverage is weakest.)

Since one of the solution is a kernel fix, maybe you can get one of the nice kernel developer to look at it to see if they can include it within their custom kernel
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:

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 have a stock t-mobile s7 edge device. It's losing the mobile network. I've noticed it a couple of months ago - it happened a few times but recently the problem is getting worse. It already happened 3 times this week.
Seems like completely random. Sometimes I notice it after I go somewhere with weak signal or no signal at all. Sometimes when I get back to an area with good signal it reconnects and sometimes it doesn't. Sometimes it shows the bars and says it's connected to t-mobile but 4g doesn't show up at all. So you can call but no internet. Sometimes no signal at all.
When it happens the only way to connect is to reboot the phone. Nothing else helps. If you try to connect to network manually - it can find t-mobile but unable to connect. just spins. Changing from lte to 3g or 2g also doesn't work.
I even tried to create a new APN - same thing.
Please heeeeelp...........
Last time this happened to me on another device, it was the sim card that had a problem. Have you tried with another SIM card?
No, but I don't believe it's a sim card related problem. Wife's phone has the same problem although less frequently. But she also travels less.
It looks like a configuration / firmware or maybe hardware issue to me.
I'm experiencing the same issue. It seems to happen when the phone loses signal completely like when deep inside a building. Then it won't reconnect to data or the network by itself.
From the first moment when I got my edge back in April I noticed that the radio performance was weaker than other phones. Then I got the Note 7 and same issue again. Then back to an s7 edge and the problem seems to be worse on this one specially after the latest software update.

My wife (s7) and me (s7 edge), as well as a co-worker (s7) are having this same issue.
Before it was happening occasionally, but after the last update its happening WAY more often.
Wiping cache seems to help with frequency, but still did not eliminate the problem. Hopefully it gets fixed with an update. I'm not sure how much longer I'll be able to put up with it.
Edit: I forgot to add a "simple" fix I've found that works almost all the time is to turn off mobile data, turn on airplane mode, turn off airplane mode, wait for signal, then turn on mobile data. Those steps in that exact order work for me most of the time.
So I've been having the same issues as everyone stated. The only fix is to reboot the phone, but who wants to that every time. I even changed the sim card!! I wish T-Mobile would get out of their feelings and start selling more flagship phones.
I have made the decision to jump to LG V20. I hope this issue doesn't exist with the LG.
I've just got my s7 edge and I'm sort of having same problem at home got 2 bars and sometimes goes to 4 bars but also wen I called someone the line was crackling but person said could her me fine so done a wiped cache and think it's sorted it now for the time being
(Edit ~ it's done it again could hardly hear person I was talking to)

so this is the second S7e and second SIM that I have been having this issue with. The phone will lose connection to the mobile network and the ONLY way to recover is to reboot phone. Reset Network Settings doesn't do anything. Toggle airplane mode doesn't do anything. Search for Network Operators doesn't do anything. I have a third phone on the way - but has anyone around here heard of or experienced similar? Am I missing something that I should be doing to correct this?
Thanks in advance
I too have this problem. Got a replacement refurbished phone under warranty and the phone has this problem

Did you pay the $20? I didnt want to pay the 20 so i sent the device to samsung. Should get it back friday or monday. The issue is definitely phone related. Im using a verizon s7 now and no issues like that arose. I even tried new sim.. My father is having same issue t-mobile s7 edge
Yes i had to pay 20. And it's disappointing I am having this issue with the replacement phone. I am having this problem on the U firmware as well.

I've suffered the same issue from time-to-time and just do a restart....annoying as hell to be honest
Are you guys always in the same location when this is happening or is it just whenever and wherever? Or is it happening a one certain place where cell signal isn't that great? I had this same issue BUT only in my house so I had to get a network range extender from t-mobile to use at home.
This happens to me all the time. It's so annoying. At work, in the car, at home--it doesn't matter where I am. Have reset firmware multiple times and even rolled back once too. I think it has to do with the latest software because I never had this issue before the Fall/Winter. Hopefully Nougat fixes this!

I happens randomly in different places. For me i lose complete signal, and then only get back signal without data. I have to restart when this happens to get back data. Annoying as hell !

I am having the same problem, this will be my 3rd phone 4th sim. I wish I knew how to fix it
I would try flashing different radios/modems, its worth a shot. Maybe try flashing the "U" firmware radios.
Nougat will fix it
My wife and I had the same issue on our tmobile s7 edge ... we got the 7.0 beta and now the issue is gone .... I bet it's radio and software related ... 7.0 will be out by the end of the month hope that helps...
I had this issue with my phone, and it was a huge pain. The biggest concern: I didn't know when my phone was off network (voice, data, etc.). The fix, for me, was simple: a new SIM card.
You may have an issue from a rejected permission on an app.
Had the same issue before but I did a hard reset and realised that I changed permissions on an app that wasn't written for 6.1.

I hope so! Been waiting for that before I try anything drastic, even though this issue is a huge pain in the ass. I'm glad others have come out of hiding to express their concerns with it as well. I thought I was the only one for the longest time having this issue.

Many of us have tried new SIM cards, but it's worth a shot if it's still not working consistently after Nougat is released.

My and my friend's phones are both running pure 100% OEM Tmo stock without any apps disabled or touched at all and we have this issue and have done multiple resets. Pretty sure it's an actual hardware defect, or hopefully just a software one with the modem/radio.

I was thinking about going that route. But I wasnt sure what condition the phone would be. How was you condition?
I sent mine to samsung and the things they replaced is the Coaxle cable "antenna" replaced 3 of them. I have been using the s7 from verizon on the U firmware so havent seen if it is fixed.

I received a refurb. Other than this problem, the phone is alright. I noticed this problem on receiving the phone it was running on T firmware. Then I switched to U firmware and radio but no difference. I called customer support yesterday, they said to go to a retail store to get the phone replaced. My worry is going through this process again and if I receive a bad device again what to do? After all refurb phones are like playing Russian roulette!

I just had this start happening on mine... I really wish they would release nougat already. It is ridiculous they won't post an Odin flashable version of the release candidate if it does indeed fix the issue.
I also think its a specific tower configuration that is causing the issue that the radio can not understand. (Maybe 3xCA). Its happening in the same areas every time.
I just started having this problem in the past month. All at once I've been getting BT sometimes turning off, mobile networks failing to reconnect after I visit a no/low signal area (such as after a plane trip when the phone was in airplane mode). I've also seen wifi mode fight my attempts to turn it back on sometimes - toggling itself on and off a couple of times per second until I poke at enough settings to stop it. When BT turns itself off I have trouble turning it back on, sometimes it just goes back on, sometimes it refuses after a number of tries and if I wait an hour it goes back on just fine.
The folks at a BB Samsung kiosk said they could reflash it if I wanted to go that route, but that the nougat release would be out soon so it might be better to just wait for that. Has anyone had a Samsung rep re-image their phone to try to solve this?

If you were able to fix without a reboot you didn't have the same issue as this.

I guess I wasn't clear about that as I have several problems that are probably related, but behave a little differently.
BT dropping - can usually turn it back on, but sometimes it refuses. Usually don't need to reboot to fix this.
Wifi dropping - often have trouble turning it back on and have seen the widget toggle off and on repeatedly by itself. Sometimes have to reboot to fix that.
Mobile Network data (and voice sometimes) dropping - usually have to reboot. I think I may have recovered that once without a reboot, but the other few times it's happened in the past month since it started I have rebooted and that fixed it in all but one of the reboots - one time I rebooted and still had to fiddle with it a bit after the reboot before it came back. That may have been because I played too much with the network settings before the reboot and so had to undo that damage after the reboot. But, definitely rebooting is a fairly reliable step in fixing this problem.
All 3 started happening around the same time which is why I thought it was a software issue (I remember a small update a little over a month ago, but forget the details of it). It's nice to hear that others also have the mobile network problem, but if that is isolated in those cases then maybe I'm not seeing exactly the same problem. But, it is clear that rebooting is almost always required to get my mobile network data back so that again suggests that at least that part is the same as what this thread is discussing.
In looking at the T-Mobile updates page for the S7 Edge I see that the version I have (G935TUVU4APK1) was updated in early November - which tracks when I started having problems, and it includes a fix for "Domestic data roaming improvements", which definitely sounds like they may have played with the radios.
I am so ready for the Nougat update...
