I'm a total newbie so please bear with me. I have a problem where whenever I reboot or after several hours I will have no service and won't be able to connect to my network operator. I have searched around and tried various things to try fix this but the only solution I've found is only temporary which is to put my SIM card into my old phone and then place it back into my GS2 which will give me a signal for several hours before it drops again.
I'm thinking it's probably a hardware problem but I wanted to see what you guys have to say.
Thanks,
I actually have a problem that sounds like it. When I leave my phone charging a long time and reboot it with the charger connected, it doesn't have service; the same happens when i turn it off and leave it charging, then (whithout disconnecting the charger) I turn it on.
Isn't it your case?
Are you running a custom rom? It could be your modem.
I was initially on CM9 and flashed Resurrection remix to see if that was the problem. I also tried flashing a new modem but I'm still getting the same problem but this was only recently and I've read that I should wait for a few days to see how well the modem works? Also since then, I haven't seen the error while running only, after I've reboot.
I've flashed a few modems and the problem still persists.

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:
http://androidforums.com/samsung-ga...connectivity-but-no-idea-why.html#post2722784
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 got my phone back on Wednesday from the repair people that my insurers use after dropping it last month and shattering the screen inside (fortunately the phone itself still worked properly)
At the time the phone had been dropped, I was having problems with it in that the phone couldn't get a phone signal at all and I was going to fix the problem myself. The repair people knew that it had been jailbroken and I explained that I would fix the problem with the lack of signal myself.
Now, I have a new problem in that every time I get a WiFi signal, it keeps getting disconnected within seconds and I've noticed that the repair people seem to have reactivated the infamous "Flight Mode" problem which seems to have somehow affected the inbuilt WiFi system in that every time the phone manages to detect a signal, whether it's at home or elsewhere, such as university, it loses the signal.
In any case, does anyone have any suggestions on how to fix the problem (I installed the latest VillainROM yesterday which is 3.0) including what modem to use and how to install it?
I would try some different modems and see if you find one that solves your problem. In the first few posts of the VillainRom thread is a link to the thread attachments. Included in there should be a few modems in zip format which you can flash through CWM. Also some of the posters (I think one is geko95gek??) have them in their signatures.
Hope this helps

Hey there, not sure whether this is an ongoing issue, but the problem seems to be related to the embedded kernel from VR 3.0 (Nimphetamine 2.0.5) I was facing exactly the same problem. The only way to fix it was to flash a different kernel (siyah 2.2 in my case) .
I tried all available radios but nothing fixed it, maybe pulser has to take care of it in the next release, so flash another kernel and the problem will be solved, good luck!
Yep, as in above post. WiFi drivers are found in the kernel. Try Siyah, Speedmod etc.

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

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?

so i have this problem for about 3 months now,
so I'll explain the problem I am facing,
I'm connected to wifi unless I'm an inch close to the router, so if I go away, the connection will be disconnected, however, in my work, I am connected to an access point which has put a big smile to my face, but apparently when I went back home, I faced the problem again, and I guess I would be connected to that only access point, which is the first time I've seen since i got this problem, all the routers/modems I tried to connect was a failure(saved, secured) since my phone met this access point.
I already tried Factory Reset, Flashing custom modem, *#0011#, deleting data/misc/wifi, changing settings on router and many many more as I've put an hour of fixing this every single day. none of this works. for what I recall, all I did was download an GPS app(I don't remember what it is) and then poof, wifi is doomed.
I have my iPad and my laptop connected and there's no issue with them, only on this phone.
I'm running 4.3 btw,
does anyone know how to fix this problem? my brain hurts a lot and I don't know what to do. please help I'm dying, thank you

Hey Guys
I have some questions related to my 3 year old LG G3 (32gig Version), which acts funny within the last few weeks...
First of all, my phone is not rooted (I use Android 5) and I have installed a new battery like 3 months ago.
So now to the problems:
My Phone will only very rarely connect to any WiFi I normally use. Even if I try to manually connect and/or forget the network and reenter the codeword, it won't connect 9 from 10 times. It says connecting.... and then saved.
So normally, I then turn of and on WiFi on the Phone, reboot the router, reboot the phone and eventually it's going to work, but it may take 10 to 15 times.... Does anyone know, what might be the problem?
Next, if I reboot my phone, sometimes it will not recognize my Sim-Card, even though it's always inserted. Here too, I reboot my phone several times, untill it recognizes the card again. But if it does, it always changes my phone language from English to German (well, thats not a big issue for me, just wanted to list it aswell...)
And the last problem, which is also wlan related: For 2 weeks now, I'm no longer able to find the phone-hotspot on my Laptop. It worked without problem before, but now, I can't even find it in the Networks list from my Laptop.... I fear, that this might be related to my phone not connecting to WiFi Networks, alltough this works at least some times and my phone sees all the networks....
So what you think? Is there still hope for my phone or do I have to get a new one? Would be a shame, cause I really like it otherwise...
Thanks a lot for your help

same problem here.
Were you able to find a fix? Its a hardware issue, I think
