Can't turn wifi off. - Galaxy S II Q&A, Help & Troubleshooting

Recently I've been unable to turn off the wifi on the phone. Everytime I turn it off, it stays off for fraction of a second and then turns back on.
I think this started to happen when I changed my a sim card
Even flight mode behaves the same way.
Any help would be appreciated.

Factory reset may fix this. A full flash should most definitely fix this unless you have a hardware problem, which I doubt.
Btw, heard many complaints about wifi not working, but this is the first I've heard about it not turning off .

I can turn it off now. It suddenly started working. Weird...
I even rebooted my phone earlier and even took out the battery but nothing fixed the problem.

Turns off while charging

Hi all,
I've searched for an answer and couldn't find one.
My Galaxy turns itself off while charging and most of the time, I have to take the battery out to turn it on again.
Anyone else have this problem?
Thanks

First, caused by AC charger or USB PC or both ?
Your firmware version and rooted, mods etc ?
Have you tried a factory reset ?
Different chargers and cables etc ?
Sent from my GT-I9300T using xda premium
Only by AC charger I think. I've only got the one which came in the box.
It's a standard phone, not rooted or anything.
I haven't tried a factory reset, will try that tomorrow if it does it again tonight

op says his turns off WHILE charging, so yours and his isn't doing the same thing.
Actually, mine is doing that too!
This morning, it turned itself off while charging, then when I turned it back on it froze, and then when I rebooted, it turned off again with the blue light flashing.
I'm also finding that the screen when waking up is very temperamental to unlock.
I'm getting fed up now!

Hardware failure maybe? (I think the main reason is the AC adaptor was broken or something).
Have you try with another USB AC adapter?

I think it might be something to do with wireless being on. Sounds stupid, but when I have wireless on, I get the screen freeze and the turn off while charging.
Going to try the rest of the evening with no wireless and see what happens
Sent from my GT-I9300 using XDA
Well, I tried the wireless off and charged and it was fine. No screen freeze or turn off during charging.
As soon as I turned it on this morning, screen froze when it went into sleep.
Luckily I I have unlimited data!

Have you bothered to Factory Reset ?
Sounds like WiFi drivers though.
Flash another kernel would must likely fix it.

Did anyone get to the bottom of this? I just received my replacement phone and sure enough, phone switches itself off when wifi enabled.
Then I saw the *#0011# trick to turn off wifi power save mode.
Hi,
No, I haven't got this sorted yet. Still does it with me and now my wifi and data keeps dropping out!
Going to send it back to 3 and let them fix it. My friend as one and his is fine

The thing i mentioned above your post works but not sure if that's the answer.
Hi again,
Well I rooting and putting a new ROM on and, though it didn't switch off while charging, it does still freeze when coming out of sleep.
So I'm getting there!
Sent from my GT-I9300 using xda app-developers app
Try to check the temp when charging, I read somewhere that if the phone overheats it will shutdown automatically. About the freezing issue, try to do a factory reset first, maybe some apps that you installed are causing that.
If still the same, maybe its a hardware issue.
Hi again,
Sorry to keep going on about this, but the problem has been solved!
Basically, the new firmware update has sorted the problem. No turning off while charging, no freezing when coming out of sleep - its perfect!

nope that didnt work damn it lol, its not a big issue at the mo, but on resale point of view its not good
Check your settings.
Go into developer options and make
Sure " stay awake " isn't checked,
As this forces the screen to stay
when on charge
Sorry just re read your post
and see exacly the opposite
is happening with your phone

Which Rom are you using??
This problem started when I flashed the 3rd preview build of cm10.. after that I flashed back to stock ics but still the problem was there.
If you put the battery back in immediately after pulling it off, the phone will turn on again by itself.. you have to wait for some time and the put the battery back.

I will try that see what happens, took battery out for 2 hours see if that worked and nothing
Sent from my GT-I9300 using xda app-developers app
Try re-flashing? Otherwise return it.. should be covered by the warranty
Had the the same issue, only a complete wipe solved it for me.
Sent from my GT-N7000 using xda premium
Go to settings-storage-other and tick everything. You will loose some data. Then reboot to download mod and flash firmware again. Now the problem is solved!
All sorted thanks to uvaman, used task manager shut down running apps took battery out and left over night, thank to everyone that gave advise

Screen doesn't turn on sometimes?

Have to hard reset it or plug it in to charge for the screen to turn on. Anyone? Experience this?

I had it happen once, but not in a couple weeks and plugging it in, didn't work for me. It acted like it was turned off, but required a hard reset to turn on.
A little annoying but just a minor flaw. Has happened to me once. Yesterday, actually.

Phone reboot problem

When I first got my GN2, I had an issue with it rebooting, this wasnt a huge issue as it usually only occurred once a day maybe every other day. I am now unlocked and rooted, running Cleanrom, and it still occurs occasionally, sometimes it won't even reboot it will just freeze my display will be off from not using it for awhile then I will pick up my phone and running to wake it up and nothing happens. My LED will be flashing blue though and the only way I can reboot is to pull the battery. Like I said not a huge problem because it only happens once every couple days. Does anyone have any ideas on what could be causing this?

You should have exchanged it. Rebooting on a stock device is unacceptable.

[Q] My note shuts off as soon as Rom boots..

Hello, I am having a problem with my note and it is scaring me. As soon as my note boots it is shutting off completely and restarting. I was just using it with fine last night. I had the uber kernel installed and oced to 1.9 cpu but it wasn't even that hot.. After thinking it was the Rom that was causing this I did a complete wipe and flashed the candykat Rom, upon boot when the cyogenmod log in screen appears it shut down and rebooted again.. twice. I'm hoping nothing is damaged internally. I am able to stay in the recovery just fine without any problems. Please help me.. And when I say shutdown I mean insta black screen and reboot..

Idk if I will do that lol. But now I think I know what the problem is. So yesterday I was using my note and it shut off. The battery was full and when it restarted the battery all the sudden dropped to 60%. It turned off again and went to 1%... I thought it was glitching when it said 1% but after amin it shutdown due to low battery. One thing I then tried was having my phone plugged in while using it and I played games, used my phony heavy and what do you know.. It didn't turn off. So I'm thinking I have a bad battery. PS: I took my note to a pawn shop and they said the battery was bloated. He said it wasn't supposed to spin while on a flat surface.. What do you think?
It seems while I'm playing a game the battery heats up and that causes shutdown cause I'm typing this and I don't have my charger plugged in and its fine..

Yes a bulging battery is a sign that it's bad. Batteries are cheap. Especially on eBay. I buy an extra battery and charging dock for all my devices. This way one is always fully charged, and I don't have to plug in the device unless I need Odin or to file transfer. I learned that lesson 2yrs ago when my usb charging port went bad.

Yeah it has to be the battery. Earlier today when I was using my note it said low battery at 2%, I looked at my phone afew minutes later and it said 4%?? Lol. The charger wasn't even plugged in.

If my power button was stuck would I see the shutdown menu before it rebooted, shutdown, reboot, sleep, etc? I'm just trying to make sure my battery is the problem.. I don't want to deal with a power button..
Sent from my SAMSUNG-SGH-I717 using XDA Premium 4 mobile app
No you won't see the power menu. It just keeps restarting. I don't think you'd even see your home screen because it restarts before the rom loads.

Oh well then. That's awesome because I'm able to use my phone for more than 5 mins without it shutting down. It usually shuts down when I start playing a game or something intensive. So it has to be the battery! I'm really happy.
Sent from my SAMSUNG-SGH-I717 using XDA Premium 4 mobile app
Well my phone shut off again when using another not as bad but still a bit puffed out note battery. I don't understand what's going on here... I'm scared to buy a new one thinking that It won't work still... my phone never turns off as much when the charger is in... But guaranteed with battery only. Less than 10 mins.
