Wifi and Blue tooth problem - Galaxy S II Q&A, Help & Troubleshooting

Hello friends,
My first post on this amazing forum.
Recently bought s2.. When I try turning on Wifi, the phone automatically gets switched off.. Can turn it on only after taking out the battery and putting it back.
And when I try turning on blue tooth the phone automatically gets restarted.. Please help.. I bought this phone without bill so couldn't take it to service center.
Thanks in advance
Ganesh

Used or brand new phone?

Can you please give details about your phone? Model, ROM, kernel, is it rooted? Perhaps a screenshot of the "about" section?

No, rooting won't change anything, so no use in this case. You're completely stock, so it MAY be a hardware issue. Did it work when you bought it initially? Or has it been like that since you unpacked it?
Also, you're on 4.0.3. Upgrade to 4.0.4 and see if the problem persists. Update via KIES and do nothing else after upgrading (don't do a data wipe or anything else).

Spiralzz,
Thanks for the reply!
Wifi works 5 out of 10 times whereas regarding blue tooth, when I turn it on it automatically restarts.. Bluetooth did work initially... Will try updating to 4.0.4 and let you know the status.

Hi,
I noticed the same behavior if I am turning on the WiFi, while data communication over 3G is done at that moment. The WiFi freezes, the phone starts to heat and if to turn on the screen lock after sometime the phone will not be turned on until the battery is removed. If to look at battery usage statistic after the battery removal you will see the gap in it.
It does not happen if the WiFi is turned on while the communication over 3G is not done.
Tried to search for solutions, but unfortunately it was not successful.
So decided to keep the WiFi turned on constantly, just to avoid this issue.

Workaround I found is when you try turning on wifi and if it doesn't turn on immediately ... Just restart your phone, the wifi will be turned on, instead of removing the battery and putting it back.

@OP: If you recently purchased it go back and they'll give you another one that will not have that issue. If you bought it from someone else, well, there we can start talking about flashing and what not.

[EDIT] Also, what have you done to try and rectify this issue? Did you lick the usb port? How about sniffing the screen? Did you try that? ... Dalvik wipe might help.

Try flashing a different kernel. If you are using the zedomax kernel form galaxys2root.com that is your problem.
I had the same problem just do a wipe and redo the flash. Try aokp ROM I moved from shostock to aokp.

Do you have any other devices running off your wifi? does it even work?
either your doing something seriously wrong with the flashing proccess, your wifi is broke, or your phone is broke.
Definitely try rebooting your modem/router.

Even if other devices work on your router, you shouldn't count that out. I had a ton of wifi problems on my dinc2 but my desktop and laptop connected to my wifi just fine. I finally rebooted it and it fixed the wifi issues on my phone. Another time all it took was changing the broadcast channel on my router. It's worth a shot since it's easier than sending the phone back.

I have also had problems like this. Have you tried it on other WiFi networks? If it acts the same on other WiFi networks I think you phone's WiFi is dead.

Good point there. My router is actually on its way out and requires rebooting every now and then for certain devices to connect. I have my phone, laptop, kindle, and a PS3. randomly they will have trouble connecting, but wifi will never turn itself off on my phone
Check this post out. http://forum.xda-developers.com/showthread.php?t=1731802
The guy used some app from the play store to fix his WiFi.
ok..im still tryimg to figure out what is causing this issue..
After installing stock 2.3.4 my wifi turns on.Scans for few seconds and turns off by itself.If i enter the menu i get when i dial *#*#4636#*#* during this period and check status
wi-fi state shows enabled
but
Supplicant status shows nothing.
So i thought this issue is probably due to an error in wpa_supplicant file and i replaced it.But still wifi will turn on for a few seconds and turns off by itself.
Also if i enter stock 3e recovery it shows this message.
--Appling Multi-csc...
Installig Multi-csc
can't access to '/system/csc/ATT/system/'.
Successfully applied multi-CSC.
is it due to a problem in a currupted partition..or something like that?if so how can i correct it?i have read that if i flash stock with pit with repartition enabled it will repartition.But also read that it is quite dangerous.
can somebody help me with this...
thanx guys for replies.

[Q] O2 Phone Stuck in specific areas, with apparent signal OK

hi guys,
i am having a bit of a situation, i have a sgs2 unlocked, rooted, 2.3.4, o2 sim card and since a few weeks, every day when i am at work, usually at 09.00am, my phone is literally stuck, when i arrive it works OK, even going in/out of the tube, then at work, (2nd floor office, good reception), after doing some texts, or some browsing, . basically out of the blue i cannot do anything, text, browse the internet or call but the strange thing is that the phone shows that there is signal, 4 bars, 10-11 asu. only option is to restart, i cannot even put the phone to flight mode, gets stuck...this tells me something is happening.
i know that o2 had a massive failure a few weeks back and when that happened i was on holidays out of UK, then when i got back, this problem started appearing....o2 support suggested to check the SIM, i got a new one, but exactly same problem happened again.. i reported them the issue again, they checked the network, just one time it appeared they had some problem in the area but then no more, yet i am the only one having problems in my office, and there's other people with o2.
what is even more weird, is that this happens ONLY when i am at work, during the weekends, not at work, the phone never gets stuck.
now, this is a rather annoying issue but i found on some other forum other people with the SAME issue, so perhaps is a known issue?
as further troubleshooting, when i bought the phone, it had 2.3.3 and a similar issue was happening, the DATA was getting stuck between the tube stations, after upgrading to 2.3.4, problem was solved.
so the big question is.... IS IT THE PHONE? IS IT THE SIM CARD? o2 support even suggested to change the SIM again, should i have had a massive case of bad luck to get a faulty one, again.....i even tried one of those apps that boost the signal, nothing.
any idea guys? to be honest i didnt plan to put ICS since i don't see that many benefits, and i dont think it will fix this issue in particular, or am i wrong?
thanks guys, sorry for the long post!
gab
I would say try ICS and you will see. You can always go back if you don't like it.

[Q] WIFI SLEEP POLICY doesn't work....SUGGESTIONS?!!??

I have a GT I9100 with Android 4.0.4, the last English firmware.
If i set the Sleep Policy to turn off WIFI when screen goes off, I have no result: WIFI still goes on & on also when screen is locked. I tryed several official ROM, and to resolve this bug I tryed also CustomROM like CM...but no result. It seems like there is an Hardware problem.
I also tryed to edit "com.android.providers.settins" by creating inside the database, the string "wifi_idle_ms" (because i haven't this string by default) with a custom value.
After reading other posts, I decide to ask you, so, anyone has more informations?I don't want to install third part apps even if I know they exist...
It doesn't turn off with the screen, it turns off after several minutes. Not sure exactly what the time-out period is, but is well in to double figures.
Since WiFi is the least of your battery drains, don't worry about it.
Mmm the setting I use is wifi off when phone in sleep state. Not sure how long it takes for the phone to enter into a sleep state.

I had this problem before, but apparently not was a hardware problem from me. Other than this, and my phone kept on showing that it was being charged while unplugged, and and also showed weird signs (warning triangle with a thermometer). A visit to the Samsung customer care solved it when they fixed the circuit board.

HELP! S3 touchscreen not responding.

Since yesterday I am facing this problem.
Last evening the touchscreen of my phone just stopped responding. It happened so: all of the sudden the touch wouldn't respond. Pressing the power button to switch of the screen for sleep mode was not happening. The last thing I had done was pull down the notification bar so that so it was stuck there. I pressed and held the power button to restart and it worked fine. After a few hours again it happened. Restarted again. Worked. But now everytime its happening. It stops responding. I restart then it works for 2-3 minutes and stops responding and again Ihave to restart and again it stops after a couple of minutes.
I tried going into recovery mode and download mode and it enter and it charges properly also.
Also, last night I switched the phone off and I left it on charge annotd today morning when I switched it on the problem is still there.
please help me out
My galaxy s3 is rooted and its running on stock rom 4.1.2 and siryah kernel.
Is it a hardware problem or software? What can be done?
Another thing just happened now. It stopped responding while I was watching a video on youtube. The screen didnt respond but the video was working and after a while the video stopped but the audio was still playing!

Its not 4.2 It's 4.1.2 Using the official one. And I have been using the siyah kernel for over a month now. Never seemed to cause a problem and never updated anything.
And no I didnt take out the battery. I just kept it switched off. Anyway I will do that too now.

Should I flash stock firmwire then try rooting it again and then flash the kernel?
The thing is I used to use my phone while on charge. A friend says the circuits must have gone haywire but this doesn't seems like a hardware problem.

If u use your phone while on charge that only harms the battery (it will make it last less...but it is inevitable anyways who dooesnt use phone whike on charge)...
What would be the very best option would be to factory reset through recovery (u have clockworkmod right?) (U can save apps with titanium backup) and flash a new rom and THEN a new kernel.
If you flash foxhound it comes with kernel already backed.
BUT before doing this (nobody likes to start off fresh) just try flashing another kernel first(or try and get an updated version of siyah kernel, maybe you got the s2 variant, which has a higher build version than the s3, making it look obsolete).
