im having problems with my 3g on my phone its a samsung galaxy s 2 gt i9100 and version 2.3.3*it keeps turning on and of randomly for no reason some times it just goes of and other times it actually deactivates itself.
ive removed juice defender which i thought was the cause but its still switching on and of randomly somtimes it will last for a hour or so other times it wil go on and of every 5 mins.*sometimes i can simply switch the data mode on and of and that works but most times i have to reboot the phone and everytime i reboot it the internet is back on.
what could be causing this its driving me made as i use my phone as a router most of the time. i know its not the network im on because it happens in every country i go to on a new sim.*is there a simple solution is it a android fault or samsung fault?
anyone have a solution to this as i really like my samsung phone but this problem is really annoying.

Hi guys,
My girlfriend was complaining that her Vibrant kept turning off. I figured it was her first smartphone and she was just doing something silly to it. The only way I could re-start it was to take the battery out and put it back in.
Then it happened to me. Its actually happen to me a few times now, and now its getting annoying.
Today I was driving back from work, listening to a podcast and then the sound cut out. So I looked at the phone to see what was going on, and the phone was off. Again had to take the battery out to get it to reboot. Battery was at 65% when it rebooted.
Later that night, I opened up the browser and the screen froze. This time, my homepage loaded, and then it froze. Again, I had to take the battery out to get it to reboot.
These are the same problems that my girlfriend is having, so now I'm looking for some help.
Our Vibrant's aren't rooted.
I run Launcherpro, she runs stock Touchwiz.
Any help would be grateful.
Thanks
I found a Thread in the I9000 forum. It seems that it is a known issue with Bell Vibrant and Samsung and Bell are working on a fix.
The issue seems to be that when your in an area were signal is weak, the switching of bands causes the phone to freeze. I'm not an expert, just passing on the information found from other users.
But every time my phone and the gf phone has crashed, it has been in an area with weaker signal. My drive home is 5 minutes out of the city of Calgary, it crashed on my way home. My gf phone crashes in her locker at work, the lockers are in the middle of warehouse.
Once I find the thread again, I'll post the link.

I'm using a Vibrant T959 and I'm experiencing the same issues. My phone is set on GSM only but it random shuts off. I tried running a search on "shutting off" and "turning off" but wasn't able to find the old thread you've mentioned above.
Any help would be greatly appreciated. It's annoying as I can miss potentially important calls and not even realize my phone is off.
Thanks,

Hi,
I have bought Galaxy S2 just two months back. My wifi was working fine until one day it stopped working. When I switch on my wifi, it just scan for the network and then gets off. My other devices are working fine with the router. The same problem exists even after doing a factory setting for the phone and reseting the wifi router at my home.
There are few things worth noticing about the problem:
1) My PC is detecting so many wireless networks around here but my phone wifi detects none because it seems to me that the wifi is not even getting started in my phone ... no wifi notification symbol.
2) On starting other wifi related setting like "wifi direct", my phone hangs and it shows a dialogue to force close it.
Please suggest some solution for the problem.
Thanks.

I recommend to flash the latest stock ROM for your region.
You can find many official firmwares in Intratech's thread => http://forum.xda-developers.com/showthread.php?t=1075278.
Please read the first post carefully.
After flashing the ROM, you should do a hard rest (by dialing *2767*3855# in your phone).
Hope this will help!
im also having exact problem as defined by op...tried almost every thing.. fw update,hard rest, 2.3.5,etc...no use

Mine have the same issue. Started to force close when in wifi settings and wifi direct. Phone started to hang-up. I tried hard reset few times then it started showing "error" under "turn on wifi". Seems to be a hardware issue. Phone was working fine until yesterday. Going to the service center today. Will get back to you guys. Mine runs 2.3.6 (INU).
Does your phone lights go out when you switch off your phone? If so it is a hardware issue. I had the same problem and had to replace the mainboard. If you reset phone you will see "error" under "Turn on Wifi" option.

Can you please elaborate what you mean about the lights switching off?
I am using Galaxy i9100
android version: 2.3.4
baseband version: I9100XXKG5
When i switch off my phone, it shows the animation, then the screen turns off. but all this while the capacitive buttons (the back key and the menu key) remain lit up and continues to be lit up for 2-3 seconds after the animation is over and then turns off. So do you think my mainboard is gone? I'v had my SGSII since last summer and had wifi problem since 2 days now.
Went to the service center ... Its apparently a mother board problem and they are charging me 9,000 INR to replace it.. Heck, i would buy a new phone with that amount.. Bye bye samsung
There's this thing called warranty....

Hey guys, long time xda user but never really bothered making an account and posting lol, but **** just got serious so I need some specific help. So I have been flashing roms almost since the first day I got this phone, never had a problem not even flashing ICS roms. But in this case, I was running [ROM] Blue 2.2 Frankenstein-FishmanMod Final and it was working perfect, had battery for days, no lag , and everything was smooth as usual. Then out of the blue, my vibrant decides to shutdown(no I still got plenty of battery left), so I wouldnt call this an infinite reboot because it doesnt reboot it just shuts down every time I turn it back on! It usually shuts down a couple of secs after I turn it on. And now im having a hard time even getting to CWM. I tried odin(multiple times) but no cigar, problem still persist. WTF . Does anyone know what I can do?
You could try to wipe everything if the phone dosent shutsdown, did you try using Heimdall(I think thats the name) and what especific problem you have with Odin?

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.
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?
