[Q] wifi bug

please help, i have very annoying problem my wifi act very strange if i turn on phone and turn on wifi on phone it function normally, and when i turn of wifi on phone it turn off normally but then when i try to turn on again its not function anymore it force close, wifi turn off by itself i mustr reboot the phone to make it function again, please help ( ps i use stock rom v21 b and then 21d but the problem still there, internet from 3g work perfectly, and sorry about my english )

it happens i think for all, the reason is unkonw but all I can tell it's related to the settings, if you try to enter wifi settings you'll get a force close, the only way to fix it is to restart the phone.
I've noticed that this issue causes the battery to drain faster

I posted same issue but the thread name wasn't so clear.

I still haven't found the solution so have kept the wifi on always on but now it reboots from time to time (froyo using acura newline v3 o/c rom).
As alankstiyo said above it drains the battery in matter of minutes. If you have Cpu usage program you can check and will see one process tiwlan_wq using 48% of cpu all the time till battery dies.

I use a widget and when it dies, the light turns into a faded green that way I know that it has crashed, maybe LG doesn't even know about it or they know but don't want to do anything

LG has effed up on this phone on so many fronts they just recently acknowledged about ghost call issue. I doubt they'll be bothered to look in this issue as they keep churning out phone after phone. For me this was the first and last LG phone.
NExt one SGIII..

true, I've seen a lot of announcements, prada, 3x 3dmx but nothing regarding the "old" phones
it's like if they forget about their own existence or customers, I'm deciding this week or month to buy a xperia s or not, so bye bye o3d (after just 6 months or so)

[Q] Wi-fi is not turning on in JB PA 2.52 by Bytecode

Well I have been using this ROM for sometime now, It is smooth.
The only probelm I am facing is the Wi-Fi is not tuning on, It is very irritating. It keeps on searching on the battery drains and keeps the phone awake.
Anyone else having the same prob??
Help me out, I tried searching the Official thread but no one seem to have that problem.

[Completed] [Q] Wifi goes off after unlocking device

Hi,
Since a few days, I'm having a strange wifi issue on my Xperia SP (Android 4.3 from Sony).
When I switch on my mobile phone screen, the wifi start, I can see the icon. When I unlock my phone, a few seconds after, the wifi goes off.
I have to manually switch off and on wifi if I want to use it.
I have posted a video explaining what I see, but I'm new to xda, so I can't post the link.

I have done a soft reset, remove many unused apps, and delete some app stored data.
How can I find which application is accessing wifi in order to solve this issue?
Maybe someone had any idea to help me.
Thanks guys.
Edit: Things went back to normal, I haven't done anything more to solve this issue. Probably some magics... Please close this question. Thanks

[Completed] [Q] Constant rebooting: i9100 Samsung Galaxy S2 :(

Hi there-
My Galaxy S2 just last night started with some new weird behaviour. I had tried to use it for navigation earlier in the evening and left WiFi and GPS on accidentally... an hour or so later the phone was running hot and started rebooting (has never been super-stable, so I wasn't too concerned) - charging overnight and now the phone insists on rebooting after about 1-2 minutes.
Have rebooted into SAFE MODE, and things are relatively ok, until I open the SETTINGS> APPLICATION MANAGER... which triggers a crash/reboot almost immediately.
I've not installed any new apps for some time (nor bothered with any regular virus scanning) - and am not sure what's up with my phone.
I'd really like to avoid having to re-flash/factory reset... as getting one's phone back to "normal" can take months!
Any helpful input would be most appreciated.
Thanks in advance!!! =)

Maybe found the culprit? How to remove it? :/
Just in case anyone actually cares, I may have found some useful info...
Facebook Messenger has been very resource hungry and unstable... In my culling of apps I'm noticing it is the most resistant to being uninstalled. No matter how I find the app (in Rom Toolbox, App manager etc) - it won't let me kill it fully.
Attempting an uninstall of Messenger triggers an immediate crash/reboot.
How can I completely obliterate it?

I managed to "freeze" messenger with a lot of luck... though I can't remove it. Phone is kind-of ok... unless I open the Application Manager.
Seems Messenger doesn't want me even looking at it! (Instant reboot)
Any ideas how to remove this awful program?

Original Shield Tablet Freezes When Connected to WiFi

Hi there!
I've contacted nvidia regarding this issue (reps seems oblivious) and posted it on their official forums to no avail, so I'll try and give it a shot here.
Basically whenever my tablet connects to WiFi after being disconnected for some time (a few hours to a few days), the tablet freezes when it downloads notifications. The freezes can be minimal (like a 5 second freeze) or be quiet substantial (it can lock up for as long as 10 mins). Once all notifications are downloaded and displayed, the tablet then performs like a charm. I even got my tablet replaced from nvidia and it has the same problem as the one I sent in. Uninstalling Facebook and Facebook Messenger improves performance drastically, but when my tablet checks for notifications it freezes still freezes for a few seconds (with Facebook installed, it could lock up for 10 mins and crash the launcher multiple times). Running on max performance did nothing. I'm really curious if this is a hardware or software issue since some people doesn't seem to have this problem.
I'm running on nvidia's stock firmware (4.2) unrooted.
So here is my question. Have any of you guys experienced this problem? Were you able to solve it? How did you solve it (did a custom rom solve this)?
The main reason why I haven't installed a custom rom yet is because I use the stylus frequently and I use the touch-block feature in nvidia's stock roms and couldn't find ports of it.
Here is a video of the issue. (youtube.com/watch?v=cJrUPV7mY6s) Now there are a lot of widgets on the video, but I assure you removing all of them does nothing. I tried.

Facebook Messenger. That says it all. What other apps have you running in the background?
This definitely sounds like a software issue to me.
Maybe you're being hijacked. Who knows.

I've had this same issues since I got the tablet (K1). System reset, no non-Google apps. Happens regardless of FW; I'm on the latest update. Don't be quick to blame the OP.
Basically, every time the tablet gets a new network connection, the system hangs and becomes unresponsive for 10 seconds to 2 minutes at a time. It's obvious that it's updating all the apps' network requests. However, the thread priority should make the system hang. I've only seen this issue on the K1; never on any other Android device. Either they're using a custom network stack, or they've messed with networking priorities.

I'm on the latest update

Of Facebook Messenger? Or OS? Or all apps?
Either way, it makes no matter no such issues on Lollipop. I am just saying.
