Hi everyone,
My phone's wifi module (also bluetooth) is broken by my careless,
the water damaged it.
I can use all other functions normally.
But the problem is if I turned on wifi undesignedly, it then cannot be turned off.
The status of wifi is "Error". After reboot, the status is "on", but not work.
Thus, the system would defaultly disable using 3G to connect internet because the system considers the wifi is on.
I can do nothing unless restore the factory setting to enable the 3G internet connection.
What I want to know is that is there any way to turn off the wifi by force?
I guess (not sure) there is a config file that records all settings.
Maybe I can just edit it and change the status of wifi to off.
So where does the file locate?
Any other way that can do?
PS:
I also tried many wifi management apps to turn off it indirectly, but none of them works.
I think there must be a way to change the status of wifi except restore factory setting.
Please help me if you have an idea.
I think it would be not difficult if you just have the related knowledge.
Thank you very much for reading this.
Hi,
Just wonder if anybody is experiencing the same wifi fallback issue on the SGH-i727?
Basically, the phone doesn't automatically fall back to the previously added wifi network from LTE/4G when the screen is off. To get around that, I'll need to hit the power button once every time I enter the wifi range. When the screen is turned on by hitting the power button, I will see the 4G/LTE being replaced by the wifi icon very quickly. After that, it will then stay connected to the wifi network regardless whether the screen is on or off.
I was able to confirm this issue by monitoring the app traffic before and after I turned on the screen.
Without turning on the screen in the wifi range, the phone will stay on the 4g/LTE network forever even though the previously added wifi network is available.
I have already tried out different routers and it's still the same. SSID broadcast is on. I am thinking if there's a bug with the phone. Note that on my phone, my "Wi-Fi sleep policy" under the advanced menu of the "Wi-Fi settings" is always set to "never". Also, it's a stock ROM, nothing is modified at all.
This issue has never happened on other phones. What you think? Am I missing anything here?
After playing with it more, I noticed that the phone will never do the wifi handshake when the screen is off.
I tried turning off and on the wifi in the Wi-Fi settings. If I turn off the screen quickly before the phone gets connected to the wifi network again, it *will* remain unconnected until the screen is turned on again. =(
Did you go into the advanced wifi settings and change the wifi sleep policy?
Sent from my SAMSUNG-SGH-I727 using XDA App
No, I didn't. I've never touched that setting. The "Wi-Fi sleep policy" is always set to "never".
My phone can still be connected to wifi when the screen is off, so it doesn't seem related to the "Wi-Fi sleep policy". The problem is only that it won't do any wifi connection handshake during screen-off.
Am I the only one having this issue? I guess that's more of a software issue rather than a hardware issue?
Have you tried the AT&T wifi app? It automatically turns off and on wifi as needed
No, that doesn't help.
Yes, I do realize I'm bringing back a thread from the dead, but...
I just got a Samsung Stratosphere (SCH-i405 -- a CDMA-1X/EVDO/LTE Galaxy S phone) and it does EXACTLY the same thing. It's ironic, on the Stratosphere they added a bit of fun that CONSTANTLY lets you know there's networks (which I had to disable), but it doesn't connect to the wifi networks I do have in there until I turn on the screen I guess that's just how it is; at least it doesn't kill the wifi once it IS connected.
If anyone knows a programmatic way to bypass this, I'd be interested, and I could write up a wifi app to implement the solution. I'm guesisng it's a behavior of the drivers though and would take some custom ROM or something to fix.
You could always try to use tasker for automatically connecting to the wifi using radio antenna or maybe can't remember if possible by identifying certain wifi spot.
i just bought this phone few days ago, and i've unlocked it, root, and flash recovery.. but it seems there's a weird problem..
my wifi is always turn on, even when i'm turn off it. i'm turn on location and check for battery saving, but it seems activated my wifi all the time.
how can i fix this?
Hello!
Since I installed YOG4PAS1N0, I have an annoying problem with my wifi:
Whenever I turn wifi off, I'm not able to turn it on again. Tapping on it doesn't do anything. Entering and leaving airplane mode doesn't help either. The only way to turn on wifi is to reboot the phone. Then wifi is turned on when the phone started.
After installing YOG4PAS1N0 I didn't do anything. No app installed or any settings changed. Nothing.
Can anybody help me finding a solution please?
It happened to me just once: i switched my profile with one that turns wifi off, then turning it on again by any means would not start scanning for networks resulting in an empty list. A full reboot solved the problem, but now I can't seem to reproduce this issue. I rembember my headphones were plugged in but I can't see why that would interfere with wifi interface.
I don't use any profiles, though.
When I try to activate wifi and hit the wifi settings, my phone literally freezes for 10 seconds before I can use it again - with disabled wifi.
Hi there,
since some days I realised that my huawei watch 2 sets wifi to "automatic" by itself, while I turned it off.
Even with flight mode toggled always on, Wifi keeps turning on.
Can this be caused by an app or watchface?
Anyone knows how to easily fix this?
I usually don't need the wifi but it's draining my battery more than before.
any help appreciated,
thanks,
Christian
