Android 13 software stay connected to internet despite wifi and data off - General Questions and Answers

Hello,
I'm a newbie here so I hope I'm not doing mistakes, writting in wring place, etc. And English is not my native language...
My phone recently update from android 12 to android 13.
I noticed something a bit weird later. Here are the steps:
1- I start a software using internet (firefox, etc) . I go on some websites.
2- I set the network off (wifi off, 4G/3G/etc off) using the network screen
3- but the software can keep surfing on internet !
In fact, as long as I do not restart the software, it stay connected to internet.
I first noticed this while hearing radio on internet using VLC. Despite having put the wifi off and not put on the cellular data (proper words?), I noticed the radio keep working. It never did that on android 12: as soon as I put the wifi/ cellular data off, the connection was interrupted.
What is happening?
PS: my hypothesis is that android keeps the connection on or switch from wifi to data automatically... But I've no idea how to test it.

I think it should be that you didn't turn off both mobile data and wifi properly.
To turn off both mobile data and Wi-Fi, tap on the Internet tile in Quick settings. Then turn off the toggles next to Wi-Fi and cellular service provider’s name.

You may need to boot into stock recovery and wipe the cache, this is necessary sometimes after updating to remove any conflicting data from before the update that is causing things to be buggy.

Late answer, was kinda busy.

Thank you for your answer. I've sadly tried what you said but it doesn't change. See below for detailed answer.

Thank you for your answer.
I read here what you mean by "boot into stock recovery and wipe the cache".
But I don't know if I can do that.
I've an XR20...
The only option when going to fastboot are :
"START" "Power off" "Restart bootloader"
No possibility to wipe the cache.
While I'm at it.
I played with network option. To test the internet connection, I use termux and run
ping www.google.com
I use the " toggles next to Wi-Fi and cellular service provider’s name" to put network on off.
Here are the results in sequential order.
"Ping ok" means: internet connection available. "No ping" means no connection. (!) means unexpected behavior.
wifi on and cellular off => ping ok
wifi off and cellular off => no ping
wifi off and cellular on => ping ok
wifi off and cellular off => ping ok (!)
wifi off and cellular on => ping ok
wifi off and cellular off => ping ok (!)
wifi off and airplane mode activated and cellular off or on => no ping
wifi off and and cellular off and airplane mode disable => ping ok (!).
Then I exit termux (using the hard method (force quit)) and then activate the airplane mode, then disable it:
wifi off and and cellular off and airplane mode disable => no ping
So in fact, it looks like once an app has asked for cellular data, the cellular data are kept on, whatever the network toggle in quick setting is set.
By the way, and just in case (1):
it reminds me than when I updated to android 13, sms couldn't send anymore pics when off network. I had to update some parameters to make it work again. (From what I understand from doing a little search, you have to "allow mms when your cellular data are disabled"). Think I had to update my APN too (I used the configuration suggested on the official website of my phone provider).
Could that be the source of the troubles?
(1) good old stuff I was taught the hard way: try to remember everything you did on your computer the day it failed. Even insignificant stuff can be the cause of huge trouble...

In fastboot, connect to PC, open a adb/fastboot terminal,type this command.
fastboot erase cache
Also, try going to your system settings>apps and find the apps on the app list that are using data in the background and disable background data usage for those apps.

[Sensation] WiFi won't connect

Anyone else having wifi issues on their Sensation? It cycles through scanning, connecting, and disconnected state endlessly.
My home wifi is WPA2-AES, on a router running DD-WRT with dual radios. The Sensation of course only sees the 2.4GHz SSID.
I'm reluctant to re-download all the apps I had on my Inspire over HSPA+ when I only have a 2GB data package :/
edit: in the diagnostic menu, network state is always "disconnected", supplicant state toggles between "associating" and "scanning".
edit2: after a *real* reboot (shut down, then pulled the battery for a bit) WiFi connected straight away and is working quite well. Hope this helps anyone else who encounters this worrying issue on their shiny new superphone.
edit3: and it's back.. I've tried rebooting, pulling the battery, etc and I cannot get it to connect via wifi. I sure hope I don't need to return this thing already.
Wifi wont reconnect
Hi all
I hope someone can help me,
I have the HTC Sensation with almost 2 weeks now and i am having one continuous issue.
I have wifi set up at home the phone connects ok,however i also have a TV/Video sender,when i need to use the TV/Video sender i have to turn off the wifi(not ideal).The problem occurs when i turn off the TV/Video sender and turn the wifi back on,the phone will connect with the modem but not to the internet,Facebook,Twitter,emails will not sync,while testing i have discovered that if i "kill" facebook and Twitter and restart the apps all is ok again i.e facebook,Twitter and emails all sync.
Does anybody have an idea what is causing this ?
Rgds

Have you tried toggling the wifi settings?
How can I prevent the internet from disconnecting while downloading?
You can prevent internet from disconnecting while downloading if you are connected to Wi-Fi. Please press MENU from the home screen > Settings > Wireless & networks > Wi-Fi settings > MENU > Advanced > Wi-Fi sleep policy > Never.
There's also a toggle for best Wifi performance...not sure what that does but it does state that it may drain the battery more than usual.

WiFi/4G problem

I have noticed that there have been a few times where WiFi is connected and 4G is connected also. The only remedy is to turn off and on WiFi. When this happens, sometimes I have no data connection (probably cause they are conflicting) but this can't be good for battery.
4G mobile network still connected when Wifi is ON?!
I have this exact same problem! Thing is, mine just started showing this behavior like a day or two ago. It's doing it right now. Both my Wifi and 4G icons appear in the notification bar. The 4G icon isn't showing activity (the download and upload arrows are dimmed), BUT if I go to my "Phone Info" app, and go to Phone Information it shows:
GSM service: In service
GPRS service: Connected
Network Type: HSDPA
Before whenever I was on Wifi only the Wifi icon would show up, and Phone Info would show GPRS Service as : Disconnected, i.e. normal behavior. Now it appears there is a conflict somewhere and the 4G network is showing as connected even when wifi is on.
Now, I did make some changes recently:
1) Temp-rooted and pm disabled a bunch of bloatware - this was like 4 or 5 days ago and I didn't have the problem at all so I'm not sure if it's related.
2) I unchecked Wireless Settings > Mobile Networks > "Enable always on mobile data" - Thought it might save battery when in sleep mode.
I think the problem started after #2. I've since checked that option back on, restarted, airplane mode, battery pull etc., but it's still exhibiting the same behavior. I've never seen this happen on any of my past Android devices (a lot). If I go to the Quick Settings it shoes Mobile Network is OFF but it IS checked. It's really confusing. When you turn Wifi on, Mobile network should disconnect, but according to phone Info, mine is on and I've been getting "network issue, try again" in the Market, and "Network Communication issues" in the Speedtest app so clearly something is being affected.
This has been my ONLY problem with my Sensation thus far, and the fact that it JUST started doing this makes me wonder what I could have done to affect it.
Thoughts?
EDIT: Every once in awhile the 4G icon WILL disappear leaving only Wifi on, and Phone info shows GPRS service: Disconnected, but eventually the 4G/2G icon comes back and Phone info shows GPRS service: Connected, so it keeps trying/turning itself on even though my Wifi is connected. WTF!
i dont have the problem of having both, i have the problem that my wifi seems to like turning itself off now and then. this has only started happening since temp root also
Thanks to Sdobron from the thread I had started, it looks like the My Account/My Device app may be the culprit. You can try killing the tasks/services and see if it helps. I personally just disabled both apps like I disabled all of the other bloatware, rebooted, and it seems to have fixed the problem so far (for the last hour anyway). Now I get only Wifi icon, not both Wifi and 4G, and the GPRS services is "Disconnected" as it should be when Wifi is on.

Hmmm did you disable any apps, and if so, which? Is your Wifi sleep policy set to "Never"?

If you're on a t mo device it's because of the my device app. Open and close it or end the process in system panel and it should fix the problem.
I believe this is somewhat normal...
I have voice only plan and disabled data through the *#*#INFO#*#* menus. The only way I can get data is through Wifi, which I always have enabled, regardless when I go to About Phone -> Network, I see mobile network type HSDPA.
It seems like voice is going through the 3G/4G but not any data. Not sure why you do get the 4G popping up, I sure don't.

Thanks! I tracked down the second package name for "My Account" (one is for My Account, one is for My device), disabled and rebooted. So far so good; Wifi is connected, no 4G icon, and Phone info shows GPRS service: Disconnected as it should. I had already disabled one package but not the other. I can live w/o the My account feature for a bit and I'll keep an eye out to see if the problem returns.

You phone will always connect to data whn using Tmobile apps such as my account app. Its because they need network data, not web data, to get their info like your usage, and billing. If you manually shut of data and turn wifi on and try to open the my account app, it will give you error.
Just because you turn Wifi on, it doesnt make the data shut off. It just connects to WIFI because its a stronger signal. It will still access the 4G data for netork required information. You can manually shut off mobile data and then turn on wifi if you want.
^This is true, I'm manually switching 4G off when connected to WiFi.

Of course it does. What would be the point in having BOTH Wifi and 4g/3g/EDGE data on at the same time, all the time? That would be a HUGE drain on your battery if it were constantly using both radios and connected to/searching for both networks. When you turn Wifi on, the mobile data radio gets turned off. When you de-activate Wifi, mobile data turns back on. This is why you get much better battery life on Wifi because the 4g/3g radio gets turned off. Plus, both can't be connected at the same time or else there would be routing problems i.e., it would get confused as to which connection to use.
This is exactly what happened to my phone in that that both WERE on at the same time and it was causing no traffic to get in/out and I couldn't figure out why. Disabling the two t-mobile My Account packages solved it so it seems like
one was trying to connect in the background and couldn't but then froze the radio state. I'm not gonna re-enable the app to confirm but IIRC when you're on Wifi and fire up the My Account app, it either prompts you to turn off wifi, or it just disables wifi temporarily and fires up the mobile radio in the background, and re-enables when you're done.

Yep. If you keep the T-Mobile my account app running it will do that cause It needs the 4G/Data connection.

Right, but what I'm saying is that I wasn't running the app. It does run as a service though so I'm wondering if it was trying to connect on it's own in the background, though I'm not sure why. I haven't seen this behavior on any other devices including my Sensation before I disabled one of the My Account apps, but I'm almost positive at this point it was the culprit. Could be because I had only disabled one of them and not both. After I disabled the second, the problem went away.
Do you have WiFi sleep disabled?
If not, phone may revert to regular data until you start communicating and wake up your WiFi.
Just a thought.

Nope, sleep policy is set to "Never" and wifi sticks fine. Still happened even with screen on so wifi was def. awake. I fixed it by disabling the T-Mo My Account apps so I'm cool but maybe it can help someone else if they have the same problem. It's really weird, never seen it happen before. I wish I took a video of it before I disabled the apps. Thanks guys.

It's poor coding in the app. Nothing you're doing wrong.

ICS data slow to connect

I am running the Zero rom and it is working great. I am having one issue but not sure if it is ICS related ot not. I am currently in Afghanistan and have edge data service. When I first started using it on GB all I had to do was create a new Access Point and only had to enter "internet" into the APN, no authentication, no proxy etc. So I instaleld ICS then when to their website (etisalat) for the APN setting. They show using a proxy but still no authentication. When I use those settings it shows that I am connected to edge but I get no data down and eventually get an error about not connetcing to the proxy. Anyway, I couldn't get it to work so I used the original APN setting but had to enable "Pap or Chap" authentication. Now it works.
But, the problem I am having is that it takes forwver to get data to connect. I mean when I leave my wifi connection, or go from a place with no cell signal to a place with signal, it takes a long time (5-30 min) for the phone to establish a data connection. I try to open my broswer or other internet programs but they just fail to connect saying no network avaiable. I try turning data on and off etc but it doesn't force it to connect. Eventually I will see the edge data connection icon showing in the top bar and it works again.
Anyone have any idea why it is slow to connect to the data? I never had this problem in GB.
Thanks
Try flashing the radio from this thread, its UCLA3, the best radio in many peoples opinion for speed and connectivity. It is gb based, but that shouldn't be an issue. I was using it with ics for a long time

Thanks, I will give it a try.
Well that didn't seem to help. Any other ideas?
Thanks

Can I get my device to auto-connect to WiFi without internet?

Hi everyone,
I own a Nexus 5 and I am running stock firmware, Android 6.0 MRA58K, unrooted and bootloader locked. I use this device at work and frequently connect to a WiFi LAN that has no internet connection (by design -- I use it to talk to other devices on the network). In older software versions (I believe back in the KitKat days if I recall), I could simply turn on the WiFi slider on my phone, and it would automatically connect to the network, and I could immediately start talking to the devices I need to (this was excellent!). Then when Lollipop first rolled around, it would still connect to the network automatically, but it would realize that there's no internet connection, so it would then prioritize the Cellular Data network, preventing me from communicating with my network devices. So I had to do an extra step by disabling my data connection, then things would work properly again. (Of course, this also meant that when I wanted to jump off the Wi-Fi, I would need to re-enable Cellular Data.)
Nowadays, Android seems to remember that my WiFi network doesn't have an internet connection, so it never joins it by default (very frustrating!). So every time I want to jump on the network, I need to turn on WiFi, then manually select the network to join, then go into the Data section and disable cellular Data, and then things would be working fine. Of course, if I ever walked away from the Wi-Fi range and then came back, I would again need to manually select the network.
And now with this lastest Marshmallow update, a new Notification pops up every time I join the Network that says:
"Wi-Fi has no Internet Access. Touch for options." When touched it says, "This network has no Internet access. Stay connected? Yes/No" There's also a checkbox that says, "Don't ask again for this network". Every time I check that box, and say YES to stay connected. And yet each and every time I connect to the network, this notification appears again! (The checkbox seems to do nothing). I've looked at the Advanced options in the Wi-Fi settings, and nothing there seems to help.
So my question is, is there a way for me to go back to the "good 'ole days", where I can get my phone to automatically join this WiFi network, and still prioritize it over cellular data?
If need be, I'm perfectly fine with rooting/unlocking my phone, if I need to install some custom firmware or whatever.
Thanks in advance for any suggestions you might have!
-Tom
