Wifi turning itself off - G4 Q&A, Help & Troubleshooting

I have what looks like a slight variation on a theme reported by others....I often find that wifi has turned itself off (i.e. the wifi quick settings icon is greyed out). When I tap on the icon to turn it back on it flashes a couple of times, turns on, then turns off again after a couple of seconds. This can happen 10-12 times before it finally stays on.
Android 6.0, V20g-234-15, Build No MRA58K.
Anyone else have this problem?

Lg g4 wifi toggles
I had the same problems myself where wifi kept turning itself off as well as bluetooth. Somehow i have fixed it. Hopefully it will work for you!
1. Go on to dialer
2. Type this code *#546368#*815# in
3. You will enter the secret menu
4. Then click on Field Test
5. Scroll down to wifi test and click on it
6. Then select OTA settings and press enable.
7. Now test wifi
I am not responsible if your phone breaks or something etc.
I really hope it works for you but I can not guarantee it. Let me know if it works for you!:good:
You can try this for other models but i am unsure whether it will work.
Find code here:
It is *#546368#*MODELNUMBER#
So for the international version it is *#546368#*815#
For the Dual sim version it is *#546368#*818#
I assume for the NA version it is *#546368#*811#

[Q] enable airplane mode turns wifi off in 4.2?

i have 2 gnex phones that both just updated to 4.2, and prior to the update, when i turned on airplane mode, cell data would turn off but wifi would be left on.
after the 4.2 update, one phone continues to work that way, with airplane mode on, cell data is turned off but wifi is left on. the other phone, enabling airplane mode turns off both wifi and cell data.
i know that apps are not able to toggle airplane mode anymore (AutoAP) because of security changes but why would airplane mode work differently on 2 phones running the same 4.2 build?
both phones are running stock android, no root, no flashing.
is there a setting i'm missing? was this something in the update that other people are experiencing?
thanks for the help!
Can't you just toggle wifi back on after?

yes, but it immediately shuts wifi back off.
with airplane mode on, i can go to the wifi settings screen, and hit the toggle, it turns on, scans, finds the local wifi, connects and at the same moment it connects the wifi on/off toggle flips back to off.
just seems weird that it is happening with this phone but mine is working as expected...
Then you must go back to 4.1.2 with 4.2 gapps.

any idea why it would work with one 4.2 phone and not the other?
seems odd i'd have to backport one phone but leave the other at 4.2
This happens on my Nexus 4. Airplane mode constantly disables WiFi, no matter what. And yes the app AutoAP doesn't work either.
I have found this app, Airplane Mode Wi-Fi Tool, funny that it was made for Android versions prior to 2.0.
The actual app doesn't seem to work (to enable/disable airplane mode and WiFi), but within the app lies a nifty feature in the Preferences menu under Extras:
Keep Wi-fi On
Wi-fi on Airplane Mode
Check both of those and you should be able to turn Airplane mode on and then keep WiFi on.
Cheers.

i could check "keep wifi on" but whenever i went back to that settings page, it was unchecked again. like it was refusing to save.
the rest of the settings saved.

im on ARHD 7.0.0 and even in prior versions, when airplane mode was turned on wifi would turn off but it could be turned back on. how come your wifi stays on during the airplane mod transition?
Isn't airplane mode means disable any active radio transmission includes Wi-Fi which is sent and receive data ?
If you just wanna stay off calls why don't you just use automatic redirect incoming calls to voice mail or just simply pull out the sim card?

Airplane mode is supposed to turn wifi off (its a transceiver). However, You can turn it back on while airplane mode is activated and still have the other functions off.
That how airplane mode is supposed to work, thats not a bug, every phone ive had does this

i don't know why, but wifi always has always stayed on when switching to AP mode since i got our Gnex phones in sept. (4.1 i think). wifi even stayed enable when switching to AP mode in my old crappy kin two.
and i think it must be fairly common based upon the instructions in the $30 cell service thread, but i'm no android expert so maybe i'm wrong.

There's a lot of talk about this. Check the [GUIDE] to voip/$30/month plans. But it sounds like google moved it into part of core services or something like that. So none of the autoap type programs work any more. But one member had this suggestion below in that other thread. Gotta buy Tasker, but should be able to get back to working like AutoAP did.
Download Secure Settings. Launch Secure Settings, go over to the Helper tab and install the helper. Then go to Tasker. Go into your task and delete the Airplane Mode radio step and the Airplane mode on step. Then hit the + at the bottom left, go to Plugins, select Secure Settings. Hit edit. Scroll down to "Airplane Mode Radios" and select it, and then select "Cell" from the dropdown. Hit the save button at the bottom left and select the check mark to create the task. Move the task where it needs to be by dragging on the right side up and down. Then create a new task, Plugins, Secure Settings, edit, Airplane mode, on, save button, check mark, move to position. You can figure out the rest. Works perfectly.
Llama works as well, it's free and looks less complicated

Many thanks. Got this working after playing with Secure Settings and Tasker, works great...:good:

keep wifi on in airplane mode
I guess I have figured out how to do it with Tasker or Secure Settings.
Both have two actions like "Airplane Mode" and "Airplane Radios", so the second one doesn't turn off anything, but set, what to control with "Airplane Mode" action. Setting seems to be system wide and permanent (saved after reboot).
Good luck

I have the same problem.
I initially tried to use SBEAM to send some files between my Note II, and my friends S4.
Then, I tried to turn it OFF, and same error occurs.
I also turn it off in the settings without a problem, but it automatically turns back on.
Which I really don't know why.
Hopefully this gets a fix.

Known issue. (Not sure if Samsung knows this, the issue keeps recurring even in recent updates)
I'm not sure if there is a fix, but a workaround which works for me,
1) Turn off the NFC manually
2) Replace the NFC icon from notification panel with some other unused icon (say blocking mode)
3) Restart Phone
4) Add NFC notification panel icon back and now it should be okay and working for sometime.
5) I don't know what causes it. But repeat step 1-4 when System UI hangs and throws error.

turn nfc on and off manually about 5 times from the wifi menu in settings
then the icon works

[Q] Wifi Calling Keeps Showing Up In Quick Settings

Normally I only have 5 Quick Settings icons enabled (Quick Memo, Wifi, Sound Profile, Data, and Bluetooth), however every time I reboot my phone, the Wifi Calling icon re-enables itself and pushes itself in between the Data and Bluetooth toggles, pushing Bluetooth off of the screen. I realize that it's easy to just go back into the 'Quick Settings' settings and un-tick Wifi Calling again, but it gets really annoying when I reboot multiple times a day. Does anyone know of a more permanent solution besides just un-ticking the box every time I reboot? If it helps, I am using the Gold edition G3 from Sprint and I'm rooted. This 'problem' has been going on since I got the phone.

Does the same on the 855 model with quick remote etc. It's an LG bug it seems (someone else has posted a similar thread iirc)

[Q] Help: Physically can't turn of GPS on Note 4. Always on GPS only mode.

I have a new verizon Note 4. It's been a great phone with very few problems until recently. I can't turn off the GPS. I'm not talking about GPS running in the background of applications. I'm talking about in the Location settings I can't turn off the GPS. I slide the switch to the off position and it jumps right back to on. There's nothing I can do. I've taken the battery out, force stopped all the applications that access my GPS, and cleared my cache in the safe boot settings. Does anyone know why this is? Under "Locating Method" I can't change it to anything but "GPS only". Power Saving is grayed out and High accuracy will allow me to select it, but when I go back into settings it is back to GPS only. This isn't a huge problem, but it's concerning me that I can't decide when I want to have the GPS network disabled or not to save my battery.

You may end up having to do a factory reset. You could try downloading a toggle app and use it to try to turn off GPS.

No Wifi connection possible - Grey button in menu

Hi Guys,
I suddenly had a Problem with my phone after unlocking my Screen, that wifi was lost.
I had a look into menu and saw, that the wifi button is greyed out. I have never seen this before. Also when I activate wifi, the button becomes turquoise, but is still sluggish. Some seconds later wifi disables automatically.
My phone doesnt find any wifi anymore! equal if i am on work, at home or anywhere else.
This happend on fulmics 5.2. I did a complete factory reset and tested 5.1. again and 6.0. but nothings helps.
It once said "unfortunaely wifi had to be cancelled"... Do I have to replace any System apk..?
Please let me have your solution.
Is my wifi chip broken?
Pictures are attached...
Thanks in advance !
Please find the screenshots attached..
