So my girlfriend's Nexus S has been losing the entire voice and data network and going into no service mode, no biggie at first, just cycle airplane mode, then it went on to rebooting because you would select airplane mode from the power off menu but it would not check the box in the wireless settings menu.
After the reboot the box would show checked and airplane mode could be disabled and the service would resume. The the phone started getting stuck in airplane mode and not even rebooting it would bring it out the first few times, then it got to the point of resetting the phone, a wipe cache/data reset didn't fixed it. So off to T-Mobile for a new sim card. Rebooted the network immediately. And as of last night its back in full force and now not even a new sim will resurrect the network.
Have tried wiping, reflashing stock 2.3.3, new sim again, multiple resets, had to get an toggle widget to get it out of airplane mode and still a dead network, all this time the network in the *#*#4636#*#* menu showing unknown and is not able to be changed and reverts back to unknown immediately, OEM specifics settings button is greyed out and you are not able to disable the radio either.
While I'm going to call Samsung on Monday and I guess send the phone off, I worry about mine because it too does it but only once a month or so, but I do constantly have issues resurrecting the phone from airplane mode at times because the box will not be checked in the wireless settings menu but I can see the airplane instead of network bars, problem persists with reboots sometimes.
I also would like to add that even when the box is not checked in the wireless settings menu for airplane mode, if you click it it just hangs forever and will try to select but never will and stays grey like its turning everything off, but if the scren goes off its like you never tried.
Has anyone else seen this? I have seen a lot of people with data network issues or having to reboot to get voice network back but nothing as bad as I'm experiencing.
Both our phones are and have been completely stock and unmodified.
Thankfully we still have her Vibrant and in case I need to send mine in my Nexus One.

Have you tried restoring from another persons' pre-made nandroid backup?
This over-writes the radio firmware, you should give it a go!
I also found that I had problems on 2.3.3, however reverting to 2.3.2 gave me no problems!
Just contact me if you need any help restoring from a nandroid backup or finding the 2.3.2 backup files

Is that true? I am just on the verge of calling samsung. My phone won't connect to or display any available networks, and is pretty much now dumbed down to a small tablet. I've tried everything except another persons nandroid backup. I've been told to stay away from flashing another persons... but I'm really desperate.
If you could provide me with a backup, that would be awesome.
I'm having identical problem.
It was working fine yesterday, look back to it and now it's got no mobile network, nothing. Just the no bars and cross symbol. I've tried wiping dalvik cache, reflashing the radio, wiping data/factory reset, reflashing the rom, restoring with a backup (Backup of when I first rooted the phone) and still no signal. Nothing has worked..
Anyone got ideas on how to fix this issue?

Can you search for and view available networks?
This sounds like the CM7 powerwidget problem (3g/2g) I used it and I loss all network, phone process will crash every second, however if your phones are stock I can't think in anything causing it.
For CM7 you'll have to reflash and delete userdata or edit the sql database for the providers and change a value to 0, but you need root.
When I went to *#*4636.... my preferred service was "unknown" too, but now it is OK.
Try to dail:
*#*#4636#*#*
and find your network information.

Nope. Sits their 'searching' but nothing shows up.
In, *#*#4636#*#*, it gives little to no information. Just says nothing for current network and for GSM disconnects it has,
Sate: DvInactiveState
disconnected with last try
at 9:59AM
fail because No Error
And that time never changes, stays at 9:59AM.
As my above post suggested, I've tried doing a factory reset and reflashing. I don't think I use CM.. I flashed with Oxygen 2.1.6 (using it's kernel) but I restored to Oxygen rom and trinity kernel after it didn't work.

That is the EXACT same problem I have. I too was using Oxygen 2.1.6 and lost all connectivity. I've just locked my bootloader and flashed back to stock ready to send for repairs. That rom must be doing something >.>

I've been trying *everything* for last past few days. Nothing is working. That shouldn't stop you from trying though. Just stay well away from ODIN and those i9023 files, I've seen bad things.

Ok, it'd be great if you worked something out. I'm so glad i'm not the only person with this issue!
Anyone had any breakthroughs? *hopeful*
I wouldn't call it a breakthrough but I got somewhere!
Ended up putting a extremely thin piece of wire into the external antenna port at the back of the phone. Wasn't too keen on doing this, but my phone now has reception isn't stuck at the dreaded -113dbm.
The reception isn't good, but it's enough to send texts and have calls.
Although the area needs quite good reception for me to receive anything, and it's extremely sensitive. To get 3 bars in a place where I usually get full bars, I have to be outside. While inside it's reduced to none or 1 bar, which is enough to send/receive texts and a sort of lagging phone call (did a few tests). As mentioned before extremely sensitive. The phone seems to like it better when it's up-right. In the middle of the CBD at Brisbane I get full reception and 3G, which is fine but in the places where you usually get 2 bars, you get no signal at all, unless you're outside.
So this is hardly a fix. I will most likely be sending it to Samsung to get it actually fixed. Either that or get it fixed the same day and pay probably close to $100 so I don't have to wait 2 months waiting for Samsung to twiddle their thumbs.
Thats awesome! But I'm going to post mine off to Samsung USA tomorrow, which will take forever considering international shipping. Where could you get it fixed same-day? I'm going to try this wire thing
So it can't be a software issue, but maybe the rom overloaded the antenna and fried it or something? I'm glad we've got that far.
I've seen that nexus s has a problem like the iphone, the antenna gate. Try take the phone with the left hand looking to no touch the rear of the softkeys

Its more serious than that my friend! Thanks anyway
I got a quote from a place in Brissy called "FixMyMobile" and they said if they can fix it, it will cost $99. Although I'll get quotes from different places (if I find them) and see what they charge however I don't think I will be able to get cheaper, most likely around the same price..
So I may do that to not wait the ridiculous time it will take to get it back from Samsung.. Not sure on places in NZ though.
Yeah it seems like a hardware issue definitely. I eventually reverted the phone back to stock everything and it still happened, so that there shouts hardware issue.
Hello all,
Quick question. Is anyone losing Google Sync / Data when on Wifi ?
Happens at home and work. Never had an issue with my GS3 or One X. On cell service it works fine.
update 11/24
Seems as though its a pretty widespread issue. Also , it is an issue with the connection it self, not just google sync.
I opened up a "google issue" , if you are having the same problems I recommend posting on the thread. It can be found here:

I have the exact same problem. But it only happens at home. At home we've wep and at work wpa2. Never had an issue with my GS2. On cell service it works fine for me too.
Is android 4.2 incompatible with 128-bit WEP???
This is driving me nuts! Any ideas community??

I've noticed this too but seems to only be when the phone is sleeping? I'll turn screen on and bars will be gray and then turn blue. Did you guys turning off wifi optimization in wifi settings? I might try that next. It's some sort of power saving

hey guys,
I actually put in a google issue that seems to be picking up some steam.
http://code.google.com/p/android/issues/detail?id=40065
I have no clue what causes it at this point. It doesnt happen on all networks. Happens on my work network which is open / unsecured.
Also does it on my inlaws network which is wpa2 encrypted. However my home network which is also wpa2 encrypted is fine.
I recommend posting on the google issue to raise awareness
I added my experience, it seems to me like it's keeping wifi alive but not the Google connection. I have no issues on a Nexus 7 running 4.2 so it's not my router either but could be something specific to Nexus 4 hardware. I might try changing wifi sleep policy to never to see if at least this way HSPA will be connected when screen is off.
Sent from my Nexus 7 using Tapatalk 2
Anybody not having this issue? It's really annoying and for some reason even if I set wifi to stay on when plugged in or never it takes forever to disconnect so I still don't get alerts. Definitely appears to be an issue with 4.2 so i guess we just have to wait and hope it is fixed in next update.

It actually happens to me on both new Nexus 4 and Nexus 7. Happens on home network (WPA2).
Any chance this could be a Google server issue? My Nexus 7 on 4.2 and GS3 running CM10 4.1.2 doesn't have issue either just my Nexus 4. Not sure what's causing it on my Nexus 4 but it's driving me crazy.

I'm pretty sure this is a general Wifi issue, and not limited to Google services. I've noticed that when the Wifi goes to sleep, I no longer receive incoming calls in GrooveIP or Sipdroid. I also don't receive email alerts until I turn on the screen, and the wifi re-activates.
EDIT: I ran a simple test. Loaded GrooveIP, called GV # from another phone, GrooveIP rang. Let the phone sit for 10 minutes to fall asleep. Called again. Didn't ring. I then loaded up Advanced Wifi Lock to prevent the phone from going asleep. The first call worked, and so did the one after 10 minutes. So, this definitely seems like an issue that impacts any service depends on a reliable Wifi link - not just Google's Sync services. I ran the same test with Sipdroid, and got identical results.

That's a bad example because GrooveIP uses GTalk on the backend so you're still using Google Services. What makes this more puzzling is I went to a Brooklyn Nets game last night and they have crazy fast open WiFi at the place while my phone was connected, it appears that all notifications worked even when the screen was off. I was too busy watching the game to pay much attention but I did get emails, etc. while the screen was off and I was on Wifi. The main difference between that WiFi and my home Wifi is the one at the arena had no security at all.
I've been playing around with my router and tweaking settings but nothing is working and I'm pretty sure this is a phone software issue. What I want to find is someone with 4.2 on a Nexus 4 who is NOT having an issue. I'm starting to wonder if this is an app or Google Service sync related issue.
My Nexus 7 running 4.2 does NOT have any issue on the same exact Wifi so I'm wondering if it's some app or setting on my phone that's causing this
For me it definitely seems to occur more on unsecured networks.
Not only is it google sync but the connection in general.
Anybody with this issue brave enough to try a factory reset? If it doesn't get solved soon I'll probably flash CWM recovery, do a nandroid and then do a factory reset to see if that fixes it. At least that way if it doesn't I can restore backup.
Anyone want to try now?

Weird! So you did a factory reset and still nothing? Did you still have the issue before you restored apps? I mean like completely stock with just what comes on the phone. If you still have the issue with that, then we know it's not app related.
I might also try downloading and reflashing the system image...maybe something got screwed up in the 4.2 update??

Since I flashed Franco boot 5, the problem has stopped (i think). Flashing stock/factory reset didn't help me.

Strange then that it might fix this issue since the wifi module is stored in system and he's not overwriting it so something in the kernel itself

I have a Nexus 6P which I bought about 7 months ago. It worked fine for about 3 months, but then the WiFi started giving problems. The WiFi icon will all of a sudden go grey and there is nothing you can do to turn it back on. This has happened several times and the only option you have left is a factory reset. But there is no guarantee that the factory reset will fix the problem either. Sometimes the factory reset will restore the WiFi connection, sometimes not. I have had to send the phone back to Huawei twice for RMA and each time the phone was returned to me with the message that the technicians could not reproduce the problem. Of course, each time I received the phone, the WiFi was working and I could setup the phone. I wouldn't be writing this post if that was the end of my problems. The same WiFi issue has occurred again and now Huawei is refusing to do any further repairs on this phone claiming that they have done all necessary testing and there is nothing wrong with the phone. I can say for sure that there is something wrong with the phone because there have been times when even a factory reset will not fix the problem. I am attaching a picture which shows a blank WiFi screen after a factory reset with no networks visible. This screen is the first thing you need to get past after a factory reset and as you can see from the picture, there is no where to go but back as the front arrow is grayed out. I have updated my phone to Android N and still the same problem.
I will be sending a formal letter of complaint to Huawei management and giving them notice that a Breach of Warranty lawsuit is coming unless they resolve my problem. I have contacted Google tech support and they have been unable to help also. Any suggestions?
Go forwards with your lawsuit. I have one question, have you ever rooted before?

Hey, definitely sounds like a hardware problem but just make 100% sure it's not your router just in case. I've seen problems before with certain routers not communicating properly with certain wireless chipsets, in laptops and in mobile devices. You can always test just by getting on a free wifi at some location. If it doesn't even detect any networks and there are multiple certainly sounds like hardware. You could attempt reinstalling the phone from one of Google's official factory images .. there's a tutorial here... http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701 (It's for Nexus 5 but the process is the same, just remember the codename for the Nexus 6P is "angler")
Hope you have some luck

I was gonna say if you ever rooted, the vendor image partitions, radio, and bootloader get altered so even if you factory reset back to stock firmware you still need to reflash the correct vendor, and radio so WiFi can work. If you've never rooted before it must be a faulty Wi-Fi chip inside the phone.
I mean not to belittle you, but you have restarted the router and or flushed the DNS?
Hello Guys, I'm not sure if this is the right forum to ask something like this, so apologies if I'm asking in the wrong place, but I've searched a lot the past days and haven't found a solution yet :/
Less than a week ago, I bought a Samsung Galaxy Tab A6 (SM-T285) 7" LTE, and pretty much since day one, the tablet keeps disconnecting and reconnecting on every wi-fi I tried so far (3-4 different networks). I lose my connection for a couple seconds, causing any app running to lag a bit, then the notification that I have been connected to (the same) wi-fi comes up, and it starts working again. I googled a bit and tried using WPS button, Keep Wifi on during sleep, always allow scanning, even turned flight mode on, but the problem remains. Also, googling usually returned solutions that were aimed towards the router, although I'm pretty sure it's something to do with the tablet, since it's not just on one router. I'm at a loss on how to fix this and the only thing I can compe up with atm is to try a factory reset, which is weird, since the problem was with the tablet literally from the beggining. Any help will be appreciated! Thanks in advance

I haven't really encountered that problem on my device. If you still have problems with the device after factory reset I suggest you try to get a replacement and see if it fixes it. You can also test if the problem goes away if your device is the only one connected to the router or setup a static IP. You can also post a logcat during the interruption so that we can get a better a handle on what is happening.

Try to re-flash your firmware and then install root. There is an application that grasps the Wi-Fi, so it doesn't disconnect and reconnect everytime.

Never mind got it working by using a different browser.
Thanks for posting it, but Samsung's 'solution' [emoji55] is to simply disconnect and reconnect the wifi which I have already tried.
It's related to the device not the network as I don't have any issue with any of my other devices on the same network.
Maybe if they'd release some source code that actually worked I might be able to do something about it instead of them refusing my request.

Thanks for posting it, but Samsung's 'solution' [emoji55] is to simply disconnect and reconnect the wifi which I have already tried.

Ok, if I find a solution, I'll be sure to tell you.
+1 I'm also getting this issue like crazy on my T280
Sent from my SM-T280 using Tapatalk
Mine too. I have the T280, Best Buy has the T350 for $20 more. Has dual band wifi. Might try exchange it, but I rooted it already. Can I go back to stock without them knowing?
I was dealing with this issue although it was never more than an annoyance because it never actually interrupted my wifi connection, it just showed the little toast message that said it reconnected
I somehow magically got the device to stop doing this and I don't know exactly what fixed it, but I think the step that did it was flashing the stock firmware to the device. After that, it never seemed to have the annoying bug again.
The other things that could have done it relate to installing root and using Link2SD to disable some bloatware and moving all user apps to the SD card, but my guess is the fix came from flashing the stock ROM
I have the same problem with SM-T280 (T280XXU0AQA4), tried many wireless network and I have always disconnections. There is a solution for this problem?

It seems better since the latest update, it's done this since day 1.

Also for me since day 1
I have the exact same issue with my A6 10.1.
Posted about it a while back, I tried a factory reset, i tried clearing the cache. I took it to the service centre who did a complete software rebuild. I reset my router to factory and gave the tablet a static ip address. In the end I got a replacement, the replacement has the exact same issue. A friend bought the tablet the same day I did and has the exact same issue, they also got a replacement, their replacement also has the issue. So that's 4 out of 4.
Samsung couldn't care less, I've called customer service who suggested taking it to the service centre or getting a replacement, both things I've done. I've emailed and received nothing but generic cut and paste replies telling me to factory reset and clear the cache partition. I'm over my 30 days and can't return it. So I have a lovely paper weight and I'm back to using my iPad 3 because it may be slow as anything but at least it stays connected to wifi.

It may not be Samsung's problem but the place where you bought your tablet from. You might have to reflash it to stock (the ODIN way or the Samsung Smart Switch way). Some stores refurbish items and just take the same item repackage after thinking that it is okay to use because they just hook up the tablet to the computer without it actually connecting to the wifi.
If you want to do the ODIN way, you should try going to www.updato.com and find your software and device number and install it. There will be a guide there.
If you want to do the Samsung Smart Switch way, just go download it for the PC and it should tell you how to do it. (YOU NEED YOUR DEVICE NUMBER AND SERIAL NUMBER!)
Or if it still doesn't connect online, it might be because the host file is messed up. It is located in ./system/etc./host
I'm not sure but you should be able to find it through ES File Explorer.

Thanks but I took it to the local service centre who reflashed the firmware and it made no difference. Support told me it's a known software issue but they don't know when or even if a fix will be released.
It connects to the wifi fine, it just drops connection constantly, it shows as connected and I'm sat less then three feet from my router but try streaming or opening play store and it says no connection retry. Then you have to wait until it decides to work again, sometimes that's seconds, sometimes a few minutes. Sometimes you have to manually disconnect and reconnect wifi or turn the device off then back on. Rince and repeat.
I'll download smart switch and give it a go but I don't see it helping to be honest.

Try rooting your device and then check your hosts file and fix it. Sometimes, after when I installed Freedom (In-App purchase hack) it updates the Host file to disable it to connecting to the Internet. It should only say 127.0.0.1 Host, not something like app referrer: 108.xxx.xxx

Thanks but I honest'y can't be bothered with it anymore. As I said myself and a friend got the same tablet, we've both had the same issues, we both got replacements, both the replacements have the exact same issue and I assume it's massively unlikely all 4 tablets have host file issues. I've wasted hours of my life on this (resetting my router to factory for some reason caused my wifi printer to flail which took 4 days to fix). I've not rooted it and haven't installed anything that should mess with the host file.
I may change my mind and give it a go one day when I'm bored. I assume rooting doesn't invalidate the warranty/trip the knox etc?
I ran smart switch last night, backed up, reinstalled the sofrware then restored from backup. Only the backup didn't restore all the app settings, so it removed all the progress on the games I had been playing.

Root does trip your warranty and it is a pain in the but when you are trying to install applications like Oasis's Island app because it knows if you had a "modified" OS. So, you have to be careful on what kind of application you still want to use.
If you can get another replacement or exchange, reset your device and then hand in to the store for a SM-T350 or some other device.
I know that SM-T350's are good for games and other content like watching videos.
Hope I helped and I wish you the best of luck.
The T280/T285 doesn't have knox, so nothing to trip.
Can confirm reflashing stock did not fix it on my t280. Starting to think the only fix is to get a different tablet...
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...
