Hi,
I just started my vacation in Spain but I've run into a problem with my cell. Upon arrival I notice that the phone won't connect to mobile data. Both mobile data and roaming is turned on, and it gives me the message of loosing the data connection if I turn it off, but I don't get any connection. What's even more weird is that I can't connect to WiFi either. All other devices here manages to but not mine. When connecting to the router it reads Connecting... but it stops and the access point reads Saved, secured with WPA/WPA2. Now and then I also get the popup notifying me that there are available networks to add to my annoyance.
Does anyone know what the heck is going on? Back in Norway both mobile data and Wifi worked flawlessly. I'm running RB 4.0 on a Samsung s3 (i9300)

Hi,
I've noticed atleast 4 times that my phone doesn't connect to a mobile network from data when away from a WIFI connection.
So when I'm at home, the phone is connected using WIFI and all works fine. When I leave home, the phone should be connected via a mobile network (i have Settings>Wireless & Networks>Mobile Network set), but it doesnt seem to connect when I try and use the browser. If I restart the phone or unset then set "Mobile Network", then the phone seems to pick up the mobile data connection and function normally.
Has anyone else seen this?
Cheers,
Ash
Sometimes, mine will switch automatically but very often it will not. It hasn't been a problem for me but I agree that it should switch over without us having to manually turn Mobile Network off and then back on again. Anyone have any ideas? I'm using the Bell stock, unlocked on AT&T.
I know this thread was originally started some time ago but I thought there would be others with similar issues as mine and mashed_ash but. Please, post if you have any ideas. Thanks.
As the title states i am having issues everytime i leave my wifi connection. I use my tab at home via wifi all the time but when i go out i am having connectivity issues over 3G. I am runing Straight Talk which runs on ATT network. When i experience the problem my 3G connection shows active and full bars but if i want to use either a browser, youtube,Tunein Radio, Google Play or any app that requires an internet connection i get an connect error message. I have tried disabeling inabeling the mobile data but still a no go. What i need to end up doing is i need to restart my tab to restore full 3G connectivity. On the flipside if i come home my tab connects to wifi with no problems. So anyone know why this could be happening?
It happened 4 times on my Note 3 in the last 10 days. I'm home or at work under wifi. Go out and try to use mobile data and I get an error message that I have no connection. Yet my LTE signal shows 50% and above in signal strength. I tried to turn on airplane mode to turn it off to force my phone to latch onto the closest cell tower and it's still doesn't fix the issue. If it happens while I try to upload some files, I check my email or try to browse the web and it confirms that I have no working connection to the web. I end up rebooting my phone and it fixes the issue. It's as if the phone is still looking for my wifi connection and "forgets" to switch to cellular connection once I leave the building. I know there is a setting under wifi that says to auto switch between wifi and mobile network but it doesn't seem to make a difference.
I'm running the official BTU 4.3 release on my I9505
I've noticed two issues with 4.3
a) Wifi
From time to time, perhaps daily, my phone loses connection to my home wifi. I get a notification which says something about being disconnected -- don't remember the full text. When I click on it I get taken to the list of wifi networks and underneath my local wifi network it will say "Sign-in is required".
It may be working as designed - checking my newish BT HomeHub 5 I can see the PPP session recycled twice overnight. Oddly this was initiated by upstream admin according to the logs, not a vdsl failure.... since the hub will intercept pages when ppp is down it's possible this caused the confusion
b) Security policy
I sometimes see a notification that an app required access to system, but didn't have permission - yet when I click on the notification I get taken to a full list of apps -- how do I find out which one was trying to be naughty?
The WiFi problem can be quite annoying.
I think this is not an improvement over the previous functionality.
The idea seems to be that as soon you have to manually log in to a WiFi network Android switches to the cellular connection to make sure you are always connected.
The thing is that at my work place this means every time I get somewhat out of range of WiFi (elevator, toilet, staircase) and walk into range my WiFi stays disconnected until I remember to reconnect it.
I only have to actually sign in once a day, but as Android thinks it is a network you have to sign in to it will not automatically reconnect to that network.
Meanwhile the phone is using up my data allowance....
I'm here because I have exhausted all other options beside returning the phone. This thing disconnects from my work's WIFI when the screen is off, but it mantains connection on other WIFI's. This has not happened to me with many other phones I've had while working here, just this one. Phone mantains a connection to WIFI while screen is on, then it shuts off when screen is off. I come home, connect to my home's WIFI and alas, it works screen off. I go to Burger King, no problem. I go the mall, public WIFI, no problem.
I am the sysadmin at my work. What gives?
Already reset the phone, already called Samsung (told me to return it for another one)... I've checked various settings... just want to see if I missed something, because it all points to an issue with my work's WIFI, but why don't I have that issue with any other phone except this one?
I just checked with another person's phone, and it mantained connection screen off. I'm stumped.
8/11/17: Samsung tech indicated to wipe cache. Wiped cache / data, reconnected to wifi at home no problem screen off, came to work and screen off disconnects wifi. Used a Samsung Galaxy Express Prime with no SIM card connected to work's WIFI and no problem screen off, connects beautifully and streams no problem. S8+ screen off simply disconnects from this particular WIFI. Can't receive notifications on any app while connected to work's wifi - again, can connect screen off to other wifi's. I have this other phone that can connect to my work's wifi no problem (as well as others at my workplace). Any advice?
You have WiFi set to always on? or on while charging?
It could be the access point you use at work, an incompatibility with Samsungs Wifi sleep configuration
Hello, thanks for answering!
Well, it's set to always. I have a Samsung Galaxy Express Prime also, and it has absolutely no problem connecting to my work's many AP's and maintaining a connection (I'm currently using it with no SIM card).
