Turn off wi-fi seeking?

I often find when I'm stopped at traffic lights and stuff my phone tings... and its trying to connect me to some random wi-fi network! It also does the same at work and its increadibly annoying... especially when you're slyly texting in the toilet!!
How can I turn this off?

if you disable it when you dont use wifi
you will also save a lot of batt

I'd rather not have to turn the wi-fi off to be honest. I'd rather have a way of stopping it from constantly searching for a network.

That's just daft, takes 2 secs to turn wi-fi off and back on and that would solve your problem. And like the person above it would save your battery - which we all need on the diamond!!
There is an app out there even called wi-fi on/off, that you add to your favourite programs, and makes it EVEN quicker to turn your wi-fi on and off.
I can imagine any other solution to this made up problem would be entirely longer than just switching your wi-fi off.

Just go to Wi-Fi Settings; then go to Menu/Advanced->Turn On available network notifications and uncheck it; i think it will still search for wireless networks, but won't notify you (so battery usage doesn't decrease).
Hope this helps.

Thanks... thats exactly what I was looking for.
I knew I'd seen it somewhere, but couldn't find it again.
I use Wi-Fi for about 80% ofmy day - so I don't ever turn it off. Its just when I'm out, or in the car etc it seems to pick up stray networks!

Only problem is - every time you reset the device it resets to search again

[Q] Z3C connects to mobile internet although disabled

Hi,
currently, I don't have an unlimited data plan, but switch on mobile internet on demand, for a single day. Most of the time I'm using wifi.
Now, I own my Z3C only for two weeks. Some days ago, I was travelling and thus configured and switched on mobile internet for the first time with this phone, for a single day. I am pretty sure I switched mobile internet off in the evening.
But looking into my provider's online overview today, I noticed that since then, my phone used mobile internet from time to time (about every five hours or so). The amount of data seems to be low (<1kB), but anyway, up to today that triggered four additional days of mobile internet usage without me needing that and even without me knowing that.
Can anybody explain what's going on there - and especially how to switch that behavior off?
The phone is stock, unchanged, and unrooted (all updates installed). No MMS have been sent or received. The data usage in settings does not give any helpful information.

Your not alone, im having the same problem. I haven't found any solutions nor any reference to such problem until now. I also have stock rom, hardly any additional apps, turned off automatic updates etc. But it still connects to internet, behind my back for A SECOND, sometimes in every ten minutes, sometimes once a day. A temp solution is to delete the APN settings, but this does not solve the problem.
SO CAN ANYONE HELP US?

I have a guess. It's either Anonymous data sending or phone usage. These two .apks send anonymous data to Sony, probably even using mobile data. It's a guess tough.
Nevertheless, I have removed them since I'm rooted.

You can try Onavo, but I believe those services will be masked under OS/Android, so it's hard to pinpoint them.
Also you van try the default app in > Settings, Data Usage (Mobile Data only)

In the meantime, I found a cure: Changing Settings -> Location -> Mode from "High accuracy" to "Battery Saving" immediately stopped the network access.
According to some other forum, assisted GPS is the reason, so using either "High accuracy" or "Device only" will both cause GPS to ask the mobile network for AGPS data from time to time. It is yet unclear to me why this also happens when I have an active WLAN connection.
With that knowledge, removing ",supl" from the APN type (and saving the APN afterwards!) could also disable fetching of AGPS data from the mobile network while mobile internet is switched off, but I didn't test that yet.

Hey
thanks for the update, i'm gonna try first "device only" (i had it on high accuracy) and after the APN type change and see if i get any changes.

As far as I understood things, that will not help, because "device-only" still activates GPS and thus still uses AGPS.
Did you try it already? What are your findings?

I just checked, it made no changes (device only). Today from 00.00 to (strangely) 11.00 clock, is the internet on/off count 53 times. I can see that the connections were 0 sec and 1 kB. So what now?

So i switched GPS off all together, and it seems to be working, no internet connection has been made. I also noticed that for a while the device changed the settings from device only to high accuracy itself. I deleted the ",supl" lets see what happens.

Actually the phone stopped surfing on its own before i deleted "supl" and i think the problem was google and its location history. Im going to test furder. Did you get it under control?

So, over a month has passed and i have some good and bad news. The good news is, that the problem for me has stopped(12.02), the bad news is, i don't know why. I made many changes and now i don't know what affected it. But my guess is that it was the deleting of "supl". Because in one month i had all the settings(location, battery saver etc) on and off and it didn't affect the data usage. 16.03 i got lollipop on my device and this also didn't change it back.

A wifi conundrum (unsolved)

Hi everyone
I have a profile that that kicks in every 30 mins from 8 am to 9pm, to sync my account. I have set it up to use wifi first, but if there is no wifi connection it will go to my mobile data instead.
Now here is the problem if my phone is on standby it always connects via mobile data regardless of a wifi connection is available. But if I am using my device at the time when the task runs then it will connect to wifi. I have checked my, keep wif on in sleep option and it is set to always.
Could anyone explain as to what this is happening?
Thanks in advance

What is your Android version?

I am currently using a custom rom called exodus which is currently based on marshmallow.

Check if Tasker is excludied from Battery Optimization and whether Wi-Fi is not deactivated while the phone is in sleep mode in Settings/Wi-Fi/Advanced/Keep Wi-Fi on during sleep.

yep tasker is excluded from battery optimisation and the allow wifi during sleep policy is always.

If you're turning wifi on with tasker action wifi turn on, try instead of that shell script "svc wifi enable".

Ok thanks, I will let you know the out come of this. I was using secure settings to enable Wifi as the command built in tasker, is not compatible from kitkat and onwards if I remember correctly.

I found out "svc wifi enable" command does exactly the same thing

Discovered I'm having the very same problem on cm13 and the batch jobs have been done by initialized mobile data. Finally found out a solution to initialize wifi instead of mobile data. I've no limited data plan, but wifi is more battery friendly.

Do you actually wait for wifi to connect?
Does your phone do the low power screen off wifi thingy?

Yes under normal circumstances it takes about 20 seconds to connect.
No because for some reason my wifi will only switch on if the screen is on.
I also have uninstaled my custom kernel, but this issue still appears from time to time.

There's a setting in wifi connection settings that you can set to that says "keep Wi-Fi on during sleep"
This same setting is often repeated in battery apps like powernap, naptime, better battery saver etc.
Even though the wording is the same, I don't believe they are all touching the same setting so go find those apps if you have them installed.
Also, disable all native battery savers (including Samsung 2 or 3 different ones,, doze, battery optimization etc etc just to see if your problem goes away.... Which it will. At least you'll know though

I have the same problem with Wi-Fi connection.
I have a profile to turn Wi-Fi on and try to connect when certain conditions meet and the screen is off in that case.
It seems that the phone has difficulties turning Wi-Fi on and connecting to it when screen is off. Tasker does manage to turn Wi-Fi on but the phone somehow does not connect *reliably* in all cases.
Tasker is excluded from battery optimization, Wi-Fi on during sleep. I tried turning cpu on for a short time hoping that it will connect, but still no result.
The only possible solution might be turning the screen on briefly at that moment.
If anybody has a better idea, you are more than welcome to share!

I can certainly say that turning the screen on will enable wifi, as I have resulted to this as well. But unfortunately I do not know any other solutions to try.

My Wifi is set to always "keep wifi on during sleep"
I'm going to resort to flashing stock rom again and see if that helps. As I am only using doze and amplify to save battery, all settings for that has been adjusted to the guide I found.

Before reflash, just disable xposed and see what you get... I will bet half of this soft taco I'm eating your problem disappears with greenify and or amplify. I'm not saying don't use them at all... Just make sure it works without them. I used to have some serious battery apps, but found after disabling, my battery was IMMENSELY better. And I had no config to deal with. But first things first... IT'S without a doubt, no question, a battery app setting or a system app that's being put to sleep that should be white listed

Prioritize network connection

Maybe a silly question for some but is there a way to only connect to a WiFi upon selecting it and disable automatic connection of known WiFi networks?
My dash cam is WiFi and broadcasts an SSID. My phone thinks it's a good internet connection and automatically jumps to WiFi. Essentially i have no connection whenever i drive. Obviously i could turn it off every time i get near my car and back on when i get out buuuut I'm lazy lol and I've forgotten to many times already. Anyways PCs have a priority (use other connections first) sort of thing. Is this a feature or does anyone have an app? I'll research but though I'd ask. Thanks

If you select that WiFi connection, you can disable the autoreconnect option...

Try this.
Settings > Connection > Wi-Fi > Advanced > Manage Networks > 'your car'. Un-tick Auto reconnect.
Also, under Advanced > Adaptive Wi-Fi > Network Exceptions, you could try removing your car Wi-Fi from staying connected.
Hope this helps. ☺

neither option described exists on my phone from what i can see

No way to turn off auto-reconnect

I'm using a UK Exynos model. Maybe that's the difference.
These are my settings.

Why can't you select the dash cam in your phone's wifi settings and then "forget?" Especially when you're not within range of the camera?

I really don't want to put the passcode in each time. Do you every time you connect to WiFi?

I have US unlocked and I can't find that option either. Kinda strange. It should be there ,so I would call Samsung , it might be a bug.

Wow, the unlocked version is missing features that Verizon is allowing us to use? Inconceivable!

Have you tried turning off 'Adaptive Wi-Fi' completely, turning it back on when needed?

My dashcam app attempts to manage the connection itself, you have to initially connect it through the app to enable this.
When you launch the app and go to view or download the video, it connects to the cam and does it's thing. If you come straight out of the app, it stays connected but if you exit viewing the cam within the app, it conveniently disconnects the wifi for you.
Obviously your dashcam might not be capable of this but I thought I'd post it anyway because it's an easy setting to miss on the badly translated app. I've got a DDPai cam BTW. Also, if your dashcam has an app that doesn't do this then it might be worth asking the developer to implement it.

I wonder if this will be a problem with GoPros too. They use the WiFi to connect.
I'll have to check it out when I get home.

Question Data connection is active even when on WiFi

Hi all,
I'm noticing that the data connection seems to be active even when on WiFi. Is there any option that I need to disable so that the phone runs entirely on WiFi. I looked in the developer options and keep data alive option is unchecked. Am I missing something?

Hi, just go into Wi-Fi Settings / Advanced and switch off tab (Switch to mobile data)
That's all.

Hi. Thanks for this but this option was never enabled in the first place. Anyways, it's self corrected now...aah..the wonders of the tech world

It's enabled by default just to keep your internet connection stable when wi-fi has an issues.

It will re-appear occasionally. Even if you turn off the "Switch to Mobile Data" setting, the mobile data icons and wifi icons will appear concurrently on the status bar. This happens even when the wifi connection is solid. Usually the mobile data icon disappears after a few seconds or minutes on its own. I'm not sure if its by design (for MMS or RCS or something else) or if it's a bug. But you're not the only one seeing this. My colleague has an S21U too and he shared a similar experience.

I'm suffering from the opposite problem!
I *WANT* to keep mobile data enabled while connected to Wi-Fi, but the setting on my phone has no effect! When I turn on the setting, my phone will still ignore mobile data.
I verify this by connecting to my dashcam via Wi-Fi. The dashcam does not provide any internet via Wi-Fi, but merely allows my phone to view the dashcam output and stored files. But once I connect my phone to the dashcam, then my phone has no connection to the internet. I can't force it to use the mobile data at that point. The phone is not behaving as it should. My older phone, LG G6, is able to successfully connect to the dashcam and still access the data through the cell signal.
The S21 Ultra simply cannot achieve this. I have the T-mobile variant, in the US.
I believe this is a bug. Can you get this setting to actually work? Like maybe test it by connecting your phone to your Wi-Fi router but disconnect the modem from the Wi-Fi router?
I'll post a separate thread for this, because I think it's a bug and maybe others are suffering from it without realizing.
