The problem is that the wifi doesn't turn on at all but the bluetooth work normal. The phone come with firmware from F400s (SK telecom) and the wifi had some problem from the beginning. It had one period that the wifi work normal after first charging the full battery and after 75% start turn on/off by itself.I changed tried with different roms but the situation stay the same. Most of the time the wifi problem caused phone to reboot too. After couple of changes of the roms the wifi stop turning on at all. Now I am with the stock rom of the F400L. Any one with idea?

My phone has had absolutely no problem connecting to Wi-Fi for the longest time. About a month ago, it started refusing to connect to Wi-Fi properly. If I go to the wireless settings, as soon as Wi-Fi turns on, it turns itself off immediately, and it keeps doing this over and over. I've tried different kernels (including stock), different ROMs, which sometimes fix it for a little while but it always goes back to this. Is anyone else experiencing this problem, or know how to fix it?
Hi
I got a used galaxy S3 for cheap, but wifi was not working on it. Turns out it was the antenna cable inside the phone, so I replaced that part, but it still didnt work. I downgraded the software from 4.1.1 to 4.0.4 (via ODIN), and wifi worked, so I left the phone alone for a few hours. Then I started using the phone and downloaded a few apps then all of a sudden wifi stopped working, and the phone won't connect anymore. Tried rebooting, reflashing, going to *#0011# and turned off wifi power saving mode, but still didnt work. WHen I enable wifi or bluetooth, the I/O switch gets greyed out and it just says "Turning On..." . Anyone know what the issue is? Could it be a hardware problem (wouldnt think so because it worked for a bit).
thanks!
No one has experienced this problem on their phones?

Kernel issue. WiFi drives are built into the kernel. Flash anoher stock kernel if your on stock or flash aosp kernel if not on stock

I'm experiencing similar trouble with my s3 the wifi never turns on. I've only started having this issue since I got a factory reset done because of some other trouble and now I'm sick with this new issue.
Did you find anyway to fix it yet. 923
Hi,
I've been reading the other shutdown issue with interest from the start but I think that my particular issue is different and I'd like to know whether anyone else has my exact problem.
I'm using the o2 UK 16GB version 10A/234 and this is the problem:
When I reboot the phone and it gets to the lockscreen, if the network status is "disabled" on the lockscreen and I swipe to open, the phone shutsdown and can't be started again until I remove the battery.
If I wait for a couple of seconds when the lockscreen comes up, there is a little lag but the phone works as normal.
I can replicate this issue over and over again, so it is not a random occurrence AND this is the second handset that I have had where this exact problem is present.
Does anyone else have this issue?

I'm facing the same issue. Is your device rooted?
At first every (re)boot without being connected via usb to a charger or a computer would result in a shutdown shortly after I enter my pin. After a day of usage I cannot reproduce it anymore, although it still happens from time to time, for example yesterday when I tried to send a text while having very bad to no reception. When it happens I also have to remove the battery or hook it up to a charger, otherwise the buttons/screen would not respond..
I'm thinking there is a (firmware) problem with the chipset since it always happens when my phone is trying/strugling to connect to the mobile network. I installed an app which constantly writes logs to my sd, hopefully that will give me more information about what's causing the problem..
Are you also having bad reception when the device shuts down? My previous device (iPhone 5s) had normal reception in my house, incl. a stable 3G connection, always 2-3 bars of 5. The LG G3 is constantly strugling with the connection to the network and often switches to "emergency calls only"..

This happens rooted non-rooted, stock (no added apps) and always whilst connecting to phone network. Are you on same variant as me and if you leave it for a moment before putting in your pin does it then work ok?. I'm trying to get o2 to change my handset for another model (m8) but they just want to fix my one.

Yes I'm on the same variant. Still running the 10A firmware.
Sometimes it works, but I will do some more test this evening after work and see if I can reproduce it every time and hopefully get some usable logging too.
I think this is fixed in the 10f firmware update that I installed yesterday. I haven't had a shutdown since :victory:

i was facing almost same issue except my phone crashed and don't want to boot up, haven't edited anything just started bluetooth. sometimes it start sometimes it doesn't
now it doesn't want to boot at all even charge screen gets stuck
I've recently bought LG G3 D855. Sadly, it seems to be damaged in some way. Battery seems to be drained too quickly and the phone gives wrong information about it often. It's crashing randomly, but usually after booting the system. It's rebooting after 15-30 secs after start of the system until wi-fi, bluetooth and FM radio stop working. After this, factory reset and switching bt and wifi on and off in safe mode seem to fix the problem temporarily. From what I know, switching to other battery make wifi problem permament. I've been reading about similar issues and I still don't know anybody who had the same problem and what could be the cause of it.

You can ty purchasing a new battery..... Seems to be a big g3 issue now that she is aging....
But this device is also known for similar hardware issues try to fulll charge and operate device while on charger see how it works if all is good you need a battery if it still highly acts up more than likely hardware issue. If thats the case I would try to return it
Hi!
So, if I turn on wi-fi, the phone restarts after 1-2 mins.
I already baked my motherboard, tried 3 different roms (including stock rom), but still no success. Bluetooth is working fine, even with bluetooth mouse or continuous data transfer. Wifi also work, internet speed is fine, but it suddenly restarts after 1-2 min.
Any solution?
(Sorry for my bad english )
