WIFI turns on and off constantly

when turning my wifi off it seems it goes into some weird loop of turning on and off constantly by itself, it doesn't seem to be trying to connect just flipping the wifi switch on and off none stop.
noticed it because i had a huge battery daring overnight and while trying to fix it i saw the switch going off and on all the time.
when turning it back on it seems to connect normally .
did a network setting rest but it did nothing ...
I'm guessing a factory rest will fix the problem but I'm hoping to avoid such a overkill solution :crying:
does anyone else had this problem and can help me fix it?
thanx!

original samsung rom.
just happened (i have the device for a a while everything was fine) its the android system that drains the battery in the battery status.
when i leave the wifi on it stops and works fine ...

Have you turned off ''Keep Wifi During Sleep''? I know this can drain battery.
It's not so easy to troubleshoot on an orginal none rooted phone.
You can try clearing dalvik and cache.
Turn it off and then on holding power and vol down button, then clear cach/dalvik and restart.

Try uninstall update beaming service for samsung then restart
If still persistent try uninstall update microsoft onedrive and skype then restart, just in case
I found it after factory reset (forgot internal data backup :crying and update all apps, this problem occuring after the last 3 updates (beaming, onedrive, & skype) which more suspect beaming service update make that problem

Your not alone
You're not the only one who suffer from this exact problem, on Friday or Saturday the same problem started occurring with my phone too, WiFi turns on and off in a loop and huge battery drain!
I saw an increase of 6% of battery drain per hour, so I ended up on 9% total drain every hour. :crying:
I have original Samsung Rom and phone worked prefect until now, no settings or apps installed before this happened either.

What rom version are you guys on?

I'm having the same issue. However, I'm on PhoenixX Rom. Major battery killer and has only just started happening within the past few days.
Since my phone has been unplugged, 3 hours ago, looking at BetterBatteryStats, It is showing com.google.android.gms as having quite a LOT of wakeups. 40 per hour (everything else is about 2). Don't know if this is normal as I don't remember it before the Wifi issue.
Looking into what the wake ups are caused from, Location and heartbeat were the major culprits. So i have turned of WIFI scanning when not on and also the body sensors for Google Play. We shall see.

See attachment.

Easy fix. Just disable Wi-Fi scanning.

its not a fix at all . it dosnt scan for wifi , just turning it on and off non stop.
like pressing the light switch agin and agin

I had this after installing "GoodLock" software from Samsung! Uninstalled and everything is ok

same here, just noticed I wasnt on Wifi and the switch is just flicking on and off by itself. Standard S7 with all the updates installed

Been struggling with the same for some days (4 - 5) I haven't been able to get exactly whats triggering this. I'm on stock rom with root. I've reinstalled firmware clean again and re downloaded my apps but it is still happening randomly. Some times after a few attempts to switch wifi on (even when it is toggling by itself) it manages to keep on. Sometimes restarting makes it work again. One thing I'm almost certain its that this usually happens after I turn wifi OFF and then try to turn it back on.
It's been crazy and the phone starts to overheat after a while off this on-off loop.
Any ideas?

its very wierd it started to all of us in the past few days-weeks . seems like samsung has a bug they need to hurry up and fix.

AT&T just pushed out the October Security update for the S7 family, I'm guessing something that came along with it is creating the problem.

mine did a software update last week and I've been away in airplane mode so it could have started then. I've just disabled scanning and that seems to have got round the issue and I'm now connected to WifI

I'm not sure whether it is a Samsung Issue or a Third party one... It is true that something recently affected all of us, but as far as I know, it could be a third party app that wasn't well developed for our phone.

I've noticed the same problem on my phone and it's also only started up in the last few days. On stock Sammy rom, unrooted. Will be monitoring this thread to see if the experts here can narrow down the culprit.

I had the same issue and I was able to stop the toggle by turning off the wifi scanning in Location - Improve Accuracy - WiFi scanning. It's a fix for now. I think it may be an app that may have been updates that is persistently looking for location updates.

wifi problem when screen off

Hello
The wifi goes off after 4 to 5 minutes when the screen goes into standby.
Spotify, sidesync, ... cuts
Even the ping no longer responds
If the screen remains on permanently or the phone is charging, no problem.
In the settings, the wifi is always activated
No battery power
Testing on several Internet networks
Has anyone ever had a problem?
thank you

Same issue here. Noticed it happening some time in November.
SM-G935F, stock, on DTM firmware. I can say that the issue started after receiving DTM OTA for G935FXXU1BPJK in Novemeber, and has continued after receiving DTM OTA for G935FXXU1BPLL a few weeks ago.

Been there, Done that, Doesn't matter... I've gone in and reset that setting at least a couple dozen times, to no effect. I've also tried rebooting into recovery and clearing cache before and/or after resetting WiFi Sleep. Nothing has fixed it. Only thing I can think of doing next is a restore/wipe via Odin.

If it occurred after an update, and cache cleaning did not help, the next step is a factory reset or Odin flash due to bad installation.

Issue with wifi on/off

I guess the problem I am facing seems strange, I'm on Feb 2017 security patch with Magisk installed. I turn off my wifi and after sometime say about 15 minutes later, I get a notifications from the apps that need internet connection. How is it possible with my wifi off all the time and my device is sitting idle??
First I thought I forgot to turn off wifi but later I realized that the thing is happening again and again. How is it even possible and the wifi this way stays ON for about 10 seconds before I turn off. Is it somekind of app misbehaving or a ghost trying to gain internet access lol ??
I cound not figure out what is causing to turn my wifi ON for about 10 seconds while the phone is sitting idle with wifi off. Could anyone help me please, it's really annoying and sometimes in feel scared as if a ghost is accessing my phone's wifi lol...
Edit: I figured out that Signal app is causing the wifi wake and I disabled by adding it to the Greenify hibernation list

Hi... Some of your apps seem to have the permission to enable your WiFi when its needed... Check this Reddit post:

Thank you for the link but I don't have app like Viber installed. So there should be some other app misbehaving. Would it be Signal app? I'll try to Greenify it and hope the problem gets fixed.

Help: WiFi turns itself off in idle mode

Hi all,
I have a new S5e and I'm happy to report there are no problems with the WiFi when holding it in landscape mode.
The tablet does lose the WiFi connection when in idle mode.
I use Youtube Minimizer from the Google Play store and I was noticing how the songs don't keep playing after each other.
Now when I turn the screen back on I see there's no WiFi connection and that it automatically comes back up after a second or two, allowing the app to play music again.
Edit: Mods, I just realized I should've posted this in Questions and Answers, my apologies, feel free to shift the thread
I've went through all menus/settings I could think of, including allowing the app to use the battery in the background. I haven't found the setting to keep the WiFi connection on even in sleep mode though.
Any suggestions on what I could do to fix this?
Any way to download the WiFi logs and see what causes it to lose the connection?
Thanks and cheers
Thewildwind

i have the same issue.. and was going to post it here, but you already did.... after X amount of hours i not longer hear the sound for incoming messages until i turn the screen on, or other things.. then once the WiFi reconnects bam a ton of noise as it tries to play multiple missed messages

[Solved] Screen won´t turn off - only dim down

Anyone else having a bug where the screen does'nt turn off after the designated time out is reached? I have set mine to 15 seconds but it only dims down after 7 seconds and remains dimmed forever and ever.
Only way to get phone to work normally is to restart it. But the bug keeps coming back every day, sometimes serveral times a day.
Now I have to turn off screen manually by pressing the powerbutton.
Update Solution:
I actually had locked(in recents) Edge browser into the memory so it always would be available lightning fast. I just unlocked and closed it from recents app, and now the screen shuts off normally. Apparantly there was probably a hidden ads-page active somewhere keeping the screen from shutting off properly.

Not much, only the Force all apps to be resize:able.
The screen awake while charging is off. USB-debbuging also.

I have encountered this bug occasionally, a few times this happened some web page was open (No video was playing) not sure if this was the case with you sometimes some ads or something on the web page can keep the browser active. I did not think much of it nor explored it much but will keep an eye out if it reoccurs.

Turn off Developer options for now.
Does it happen in Safe Mode?
Make sure a 3rd party app isn't the cause.
Clear system cache on the boot menu.

Big Thanks! I actually had locked Edge browser, Telegram and File Manager+ into the memory so they would never be killed off. I just unlocked and removed them all, and now the screen shuts off normally. What a relief [emoji846]!
Using Adguard adblock and Edge content blocker so it might have been a hidden ad of sorts keeping phone screen active.

Glad it worked, I suggest copy paste above text, what you observed the reason was for this to happen and what you did to fix it and add that information to the first post. Trust me it will help many.
Also change the title to: [Solved] - Screen won´t turn off - only dim down
