[Q] mobile data does not work at first try - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi,
I have the exynos version of the note 4.
Has anyone encountered this?
1. I enable mobile data
2. Notification bar shows I'm connected to 4G
3. In browser, I'm unable to connect
Disabling mobile data and enabling it again does not work, too.
So i tried to enable Airplane mode, and then disable it. It would work everytime i do this.

I get the exact same. Exynos version on stock. In and out of Airplane mode is the only thing that gets it working. Hopefully somebody has an idea why.

Try wcdma/gsm if you work.

airplane mode, auto ap, and wifi

Just got the new nexus 4 and I'm trying to set it up like my galaxy nexus. I have tmobile's $30 / month plan and use sipdroid at home to make wifi calls so as not to go into my 100 minutes.
It seems like auto AP does not work on the nexus 4. In addition, when I manually toggle airplane mode it turns off all radios and I cannt reactivate wifi (even manually in settings). Any fix for this?

You do know the point of airplane mode, right? It disables EVERYTHING.
If you want ONLY wifi, disable data in your phone settings. In 2.3.6 (N4 today!) it's wireless and network settings, mobile networks, uncheck "data enabled"
You could also get a toggle app like widgetsoid and disable background data sync, or settings, accounts and sync settings, uncheck background data and auto-sync.

Right but on my galaxy nexus I could enable airplane mode turning off everything, then turn on wifi. All I'm looking to do is disable the cell connection whenever I'm connected to wifi.
This happens on my Nexus 4 as well. I had my Nexus S setup this way as well. I use CSipSimple + PBX account, etc. Anyways, 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 wrote this a while back: http://forum.xda-developers.com/showthread.php?p=29219003
You can try to see if those apps work.
AutoAir for automatically toggling airplane mode when connected to wifi (doesn't check if there's an actual connection to the Internet though. don't know if your app does)
Plane Mode Tweaker for allowing wifi and bt to be usable in airplane mode. It can also make it so wifi/bt don't get disabled upon entering airplane mode if they were enabled previously.
Y5 for automatically toggling wifi on when in range and off when away. Since it determines location by logging the cell towers you're connected to, the phone should not be in airplane mode initially. Walk around the house and anywhere you have wifi since you may be in range of multiple cell towers. It's best to leave the radio on for a few days so it can learn all the towers. After that, it works very well.
With that battery of apps, everything becomes pretty seamless. I have it set to always use Google Voice. This way, I don't have any additional prompts when using the native dialer, and the other party sees my GV#. When I go home, Y5 turns wifi on, AutoAir sees wifi and enables airplane mode, and Plane Mode Tweaker prevents wifi from being taken down again. The native dialer will automatically trigger Sipdroid, and again the recipient sees my GV#. Leave home and lose wifi and airplane mode is disabled, then wifi gets disabled. Seamless. Only problem is calls won't handoff between sipdroid and cell obviously.
I'm kind of assuming the apps may be calling the same functions/methods/whathaveyou and it may not work either.

[Q] How to restart network services without reboot

Every now and then my Nexus 4 forgets (?) my home and work wifi, and a re-scan does not even show them in the list of available networks. The only way to find them again is to reboot the phone, and then all connections work fine for a couple of days, and then the problem repeats itself. The problem seems to happen whenever i switch off WiFi and then switch in on again. If I do that, only a reboot solves the problem.
Is there a way instead of rebooting, to just restart all network services? I found an app that says that it does that but it does not work (https://play.google.com/store/apps/details?id=com.dazbradbury.restartConnections&hl=en)
Any other app, hack, setting I could use?
I am running the latest Cyanogenmod (android 4.2.2) with Kernel 3.4.0-perf-g4857f9b
Thanks all!

Dreadful AT&T GS7 Edge Quick Setting Toggle

Alas the same fate from Galaxy S6 the dreadful no Mobile Data toggle is not there anymore, please tell me there is some sort of program that will fix this I don't want to deal with this again after kitkat and marshmallow.
I don't know of any quicker way than to drill down into the Data Usage settings (unless you want to turn off mobile voice too, in which case you can toggle Airplane Mode and then optionally toggle WiFi back on, which will also give you WiFi Calling if you have that enabled).
Just out of curiosity, why do you toggle Mobile Data so often as to benefit from a quick setting for it?
Thing is I don't like using my data when there is Wi-Fi but for some reason the data is still used while the Wi-Fi is connect, and no the Wi-Fi booster option you can use isn't on. It's quite annoying repetitively going into the connections and what not to turn it off rather than having a quick button to use in the notification dropdown.
And when I do turn it off it has that absurd mobile data turned off in the notifications it won't let me swipe it away just sits there in sure that bothers someone else. I have tried to make it go away but nothing works. Other than that I just would like to know why there isn't a mobile data toggle

I can see how a mobile-data toggle would be a useful workaround for that problem. But have you tried to fix the problem itself? Has it occurred on more than one WiFi network? When you turn off mobile data and use WiFi, does the Internet connection ever drop out?

Yes it has, no the internet connection doesn't drop out at all, I don't know what's going on but yes a mobile data toggle would be great I just don't see why AT&T supposedly removed it.
If you could get your data bug fixed, there wouldn't be much need for the toggle. Is it any app in particular that's using mobile data despite having a WiFi connection to the Internet? Or does everything on your phone do that?
Everything on the phone, and yes a mobile data toggle would still be required whether it's fixed or not, as I said having to repetitively go into the settings to turn it on and off is quite annoying especially when I need to use it.
try using Usage Manager app to toggle data..its faster than going through settings.
May I ask what are you talking about a usage manager

It's a system app. Think it has a widget, too.
Did you happen to purchase the phone from Samsung itself?
If you use nova launcher u can add a widget thru nova actions that takes u strait to mobile data settings.
Alright thanks for the help guys I had to snoop around to find usage manager apparently it was disabled on the phone, that is much better and faster

Galaxy S8 WiFi disconnecting problem w/metro pcs carrier

I have a galaxy s8 threw metro pcs and have been having this WiFi problem that seems to happen only when using an app or game that uses WiFi. The WiFi disconnects, reconnect and does this randomly and often. I know it's not my router and have seen the same issue with other phones. I have tried using service mode to disable WiFi power saving mode by dialing *#0011#, tapped the pull down menu at the top right and hit WiFi. But it then takes me to a menu where all i can do is test ping and see no option for disabling the WiFi power saving mode. I've looked everywhere for a solution, deleted my system cashe and app cashe along with other stuff, nothing has worked. Im trying this solution that I've read works for many, but can not figure out how to disable the WiFi power saving mode. I've heard the menu in service mode may be different with different carriers and I use metro pcs. If anyone knows how to solve this problem, or atleast how to disable the WiFi power saving mode (not the regular phone power saving mode), please let me know.

WLAN to 4G problem

Hi,
I got a weird problem and hope for a solution other than resetting the phone.
I have the latest updates on Android Pie. Stock Rom, rooted.
1. I`m in an area where 4G is available and working
2. I activate WiFi and connect to it
3. I turn off the display
4. I turn on the display and I deactivate WiFi
5. The 4G-Symbol is showing but mobile data is not working
until I do the following:
1. I go in options and change to 2G/3G only
2. Mobile Data is now working with 3G
3. I go in options and change to 2G/3G/4G
4. Mobile Data switches to 4G and works again
until i connect to WiFI, turn off display and diconnect WiFi again.
When theres no 4G near, theres no problem, with 3G and WiFi theres never a problem. I tried resetting wifi, mobile data and bluetooth but that changed nothing. Is that a bug with the stock rom? Any suggestions?
