Hello all..long time lurker, first time poster. Yesterday my 3g data started malfunctioning. It just won't connect at all. I've rebooted, flushed the dalvik cache, uninstalled Juice defender and a few other things I could think of. Nothign seems to help. I didn't install any new software or update any apps either. Anyone have any clue as to what could be causing this and how to fix it? Wi-Fi works fine.
I'm running superfrakenclean 2.6 with voodoo. As I mentioned before, it was working just fine and then it didn't. any help is appreciated.

I would wait a few hours.. my phone did that awhile back too.. and the next min i look at my phone and all is well again...... it could just be verizon messing with some towers around your area....

Hi,
Sometime today I lost my phone signal on my SG2. I'm not sure exactly at what moment as I first noticed that I had a couple of bars but no 3G when I tried to browse the web. So I restarted the phone but to no avail. Since then I've lost all bars and can't make any calls either.
The only thing I have done today "out of the ordinary" was to connect to the phone using Wifi File Explorer to transfer a file, which I tried to connect to without being on a wifi network by first trying the "Wifi Direct settings" in Settings, which didn't work, and then by tethering by Wifi which worked. Maybe some setting got stuck in the process, but I'm not sure since never checked if it worked right before and after.
If anyone has any idea what could be wrong please let me know, as I am literally without a phone!
I recommend downloading http://www.androidzoom.com/android_applications/communication/no-signal-alert-pro_fyyo.html this will definitely be of benefit to you if your suffering from signal problems, it has been of good use to me.
Check your IMEI is the correct one for your phone .If not restore your backed up EFS folder .
Or try backup data and factory reset as a first step.

Thanks for the quick replies!
The IMEI does not correspond to the one I have written down, though I'm not 100% I what have on my note is the latest IMEI; but how could that change though by itself, if my note is correct??
Also, I just saw something very strange: I turned on my phone and had full bars (no 3G though), and right in front of my eyes all bars dropped, one by one, during the course of 5-6 seconds. Something is VERY off...
Regarding factory reset: my phone is rooted (thanks to XDA!) and I have Tit.backup: can I will my phone still be rooted if I do a factory reset?
Something went probably wrong when rooting it (not neccesarily any errors) and effed up tge EFS folder.
Try to flash back to stock ROM, it might work to restore your.folder.

I should have been more clear on that, but I rooted the phone about a month ago and it has worked flawlessly since then, so it couldn't be that.
Anyway, I looked around a little and found this post:

He seemed to have had the exact same problem that happened to me, so I decided to wait, and sure enough the connection reestablished itself about an hour ago and while I was watching for it, with the signal slowly creeping back up during a couple of minutes, and several hours after I lost it. Very odd.
This surely has to be an Android bug but that only shows up under certain and rare conditions.
To be sure I made a speed test and got 4.84 Mbps/up, 1.19 down, which I guess is fine; I never did one prior to this so I have nothing to compare to.
Again, appreciate the advice!
EDIT: For posterity, I should add that during these hours, even when I briefly apparently had a (non-3G) signal, I had a notification during all this time saying that I could only make emergency call.
I'm having the same issue. No Bars at all most of the time and when I have some, it never connects to 3G, G at most, and can't load any thing at all.
Very frustrating. I have been using Lite'ning rom 6.1 for a few months and had no problems at all until about a week ago.
I flashed back to a stock rom and still having the same issue.
I've also seen the bars drop down one by one in a 5 second window, bizarre!
Anyone find a fix for this? Or could the phone be faulty?

I was on Lite'ning about 3 weeks ago and actually completely lost signal several times. Reboots and hard resets solved the problem temporarily. I then flashed Batista FH 2.4 with ICS and things were great. I'm now on GingerMod. No issues.
I don't know how it could be kernel related though, especially if you are 100% stock again.
I was wondering if one of you folks can help me out with a problem that my Flyer has now for a couple of weeks.
It started when my Wi-Fi Flyer started a bootloop after dropping the Wi-Fi signal. While sometimes my signal dropped before, I just rebooted my router to fix the problem.
This happened again 3 weeks ago while my Flyer was completely stock on Gingerbread, just the way I bought it. The normal procedure, did not help this time and I managed to boot in recovery,with no result. After a factory restore and install everything again it seemed to work fine for quite a while.
Then I upgraded to Honeycomb following the Globatron method, hoping that whatever the problem caused, was solved.
Just today after 2 weeks of using Honeycomb, the problem was back. After my Wi-Fi drops, it seems that my Flyer can not reconnect to my network again. Instead of this it boots again, but can not make a connection. As soon as the Flyer starts scanning for networks, it boots again.
While I am still a noob on this kind of stuff, I decided to ask the experts

Since I still not know what caused the problem, i found the solution. It seems that it just happens when the fastboot option in the settings is disabled. Not experiencing any problems so far with fastbootoption enabled
Ive searched the forums, googled, factory reset, messed about with *#0011# power save, rebooted/forgot router and I'm STILL having issues with the wifi dropping and reconnecting periodically (maybe once every 10/20 mins?) . Im on BLG8 which is as far as i can tell the latest firmware (im not rooted) for the UK.
Has anyone got a solution to this? The main reason is I use Skype a lot and the call will just drop (obviously) with the wifi drop outs.
No other device has issues with my wifi router.
Any help would be much appreciated
Cheers
Does it make any difference how far you are from the router? Does it always connect fine initially?
I'm having the same issue and i've tried every fix that has been suggested. I dont understand after spending the amount of money i did on this phone that i have to run through the dialer to get it to work properly sometimes. Then other times it still drops out and wont come back on for 5 to 10 minutes. I've changed roms, kernels, and wiped completely i dont know how many times and went back to stock. Still works sometimes and hangs up others. There doesn't seem to be a permanent fix for people lucky enough to have this issue still. My 30 day return is way up and gone so i cant send it back. Samsung cant seem to give me an answer. I'm at a loss for words.

My 30 days was up, it's still been replaced under warranty. I took it to CPW who sent it away, it came back 'fixed' so I asked them to log into their WiFi... of course, they couldn't and the guy said he would order me a new phone but it would need to come from Samsung. My new one has blazing fast WiFi!
i have the same problem. i was hoping a new rom would fix it, but FWIR its busted. i get 2 bars MAX no matter how far i am from teh router. its fast enough, but it drops out constantly.
also my screen is sometimes slow to turn on from sleep.
im on vodaphone if that makes any difference.
Guys... I had a very similar problem with my phone.
First of all WiFi became very unreliable.. like yours. I changed ROM and it still persisted. I even went completely back to stock.. and it still persisted. Dropping out.. no reliable connection etc etc.
Then it started being really weird.. the touchscreen started responding intermittently. Sometimes I couldn't get it to unlock. And this was all on stock.. no root etc.
I was ready to send it back to be repaired.. and I came to the conclusion that there must be something staying the same.. even after a wipe / reflash. Maybe one of the other partitions was corrupt???
Now I'm not clever enough to investigate.. but I did come to the conclusion that a repartition may wipe everything and make it a real fresh install next time.
So I found an appropriate .pit file and stock ROM and used Odin to flash the ROM and partition the phone.
And it is now all fully functioning again.. no WiFi issues at all.
RTFM THO FFS! Potential for complete brick if you get it wrong

just..want..to..delete this post.........and I can't...so there is now filler here....GG k thx bai
It seems to have improved with the latest JB leak, still every now and then but certainly better - i did a full factory reset + cache wipe in stock recovery (im unrooted etc). Still, would a modified kernel/modem fix this very common issue?
This problem is everywhere it seems.
OK so really weird update: my screen unlock is still a bit slow, but my wifi hasnt dropped for a few hours. i went through all the vodafone crap and updated/ran/configured it all, and now it seems fine. seemed vodafone wanted to verify my phone+sim details but couldnt over the wifi so kept trying to do it over the 3g, but couldnt do it quickly enough so the wifi cut it back out again. I have a headphone amplifier that is very sensitive to mobile phone signals. it beeps 4 seconds before i get a message or phonecall, and "ticked" at me whenever my wifi dropped out. its not ticked in hours.
TL;DR anyone on vodafone, run your "my vodafone" application and configure it all. might fix it.
Mine drops wireless a lot when connected to wireless A networks. It seems stable on wireless N networks. Anyone else notice A networks to be worse?

Hey guys, i'm Elias and this is my first post here.
i got my galaxy S3 for a while now and have been waiting to update to jellybean anxiously.
i finally got the update last Thursday, and i must say i was amazed.
Sunday night, 4 days after i updated to jellybean, I've had a problem with maintaining wifi connectivity through my S3. This means that whenever i connect it to wifi, it stays connected for about 15 minutes, then automatically stops without giving me a sign whatsoever(the wifi logo is still showing and it has full connectivity bars) although i never encountered this problem before. i checked my connection through my laptop and other phones in my house, it was stable. i reseted the router, nothing. i already have wifi power saver mode off so i tried putting it back on and it didn't work, so i put it back off.
i tried a factory reset, it worked fine for about 30 mins until i finished re-downloading most of my apps, then the problem persisted.
The only solution is that i should turn wifi off on my phone then back on, and it's frustrating to do that every 15 mins!
i really need to know if i'm the only one experiencing this because it's really getting on my nerves, and i need help from anyone.
Thanks in advance.

I had the exact same problem, but with custom JB ROMs. This is only relevant if you're phone is rooted, but I resolved it by:
- Wiping/factory reseting the phone
- Wiping the cache partition
- Wiping the Dalvik cache
- Re-installing the JB ROM
- Wiping the cache partition
- Wiping the Dalvik cache
Hi,
Ive been having this problem since today the phone was working fine yesterday...when i went to work i noticed the phone signal and data was freezing, it didnt recieved data or make calls. When i went to airplane mode before it was fast now takes a lot longer to come in and to come out. Doing this fixes it for a few seconds as long as im using it, if i dont use anything it freezes again.
Im using the stock rom 4.0.4 and i did a factory reset, the last thing i download was game but it was requiring to install more stuff and bla bla. The weird thing is that everything was working fine till this afternoon, i even call my provider and dont have any issues on the network.
Can i get some insight please? ty!
Whether your provider admits it, it sounds like network issues. Give it a day before playing with the phone software. Stuff like this almost always clears itself up.
