[Q] No more data either wifi or Cell - Galaxy S III Q&A, Help & Troubleshooting

Hi,
My phone is on Omega V43 (android 4.1.2, rooted).
I change nothing on my phone, and no app update during the night.
Yesterday evening everything was working fine, at midnight my phone goes on plane mode, back to normal mode at 6.30.
When I want to use it this morning, no more data connection (no cell data icon). I try to get into plane mode and back to normal, try to reboot the phone. Remove all APN, and manually add them back.
Nothing work.
If I activate WiFi, I get an authentication error and the phone ask for WPA key. But the WPA key didn't change.
If I put the phone into plane mode and then activate WiFi, the WiFi connection is OK. (used to, but no more working )
Please help, I've no more idea
Thanks,
Seb

It seems to be a cell carrier problem

[Q] No data connection after leaving WiFi range

Hello everybody,
I hope I can get my problem across:
I'm running my S2 on stock Android 4.04, not rooted.
After switching the phone on, I have access to the internet, and this is confirmed by the Edge/UMTS symbols witht the up/down arrows on the top of the screen.
As soon as I enter an area with a known WiFi connection (e.g. home ) the connection automatically switches over to WiFi.
Now for the problem:
After leaving home, the Edge/UMTS connection is not restored, I have to enter and leave flight mode automatically to get it back.
I had formerly installed Llama, but have removed it since, because I thought the problem was related to the program - behaviour has not changed.
I'd like the phone to switch automatically to the best available data connection.
Thanks
Robert

I'm having the same problem with an LG Optimus F6. Did you ever get this resolved with your phone?

[Q] Galaxy W - 3G connection lost after each restart

Hi all,
I've been using my Samsung Galaxy W for quite a while now, but have only recently given any serious attempt at setting up the phone's 3G connection. I have entered the correct APN data for my provider - using Telstra after unlock - and all settings are correct, as I was initially successful in getting a data connection. However, I ran into an issue when I shut down my phone. Whenever I start the phone back up, I get a glimpse of the 3G icon in the message tray, but after Media scanner has done its thing, that 3G icon then disappears. Initially I could no longer connect via 3G, no matter what settings I fiddled with.
Eventually, I found that the only way to fix the error was to dial *#*#4636#*#*, access the phone info menu, and then to manually enable the data connection. Even more confusing is that when I hold down the power button, my phone states that the data connection is already, and always was, enabled. My packet data is also on... and the phone has not put itself in flight mode. Also, as I said, the APN settings are definitely correct.
Does anyone know why I must manually enable the data connection whenever I restart my phone?
Thanks in advance for any assistance.

Phone is rooted and running gingerbread 3.3.6

[Q] Wifi and data on at the same time, limited internet.

Rooted stock ROM Verizon I605 running 4.1.2.
I was in Korea for the past 6 months and just got back the other day. Before I left, I never had any problems, but since returning, my wifi and data are on at the same time, and it's causing me problems. Here's what's going on:
If I just have mobile data on, everything works as it should. If I turn on Wifi, it will connect, but the data connection will also remain, and my internet speeds will become spotty. If I turn on mobile data and just try to use wifi, the Wifi icon appears (with the orange/green arrows indicating activity), but apps don't connect. Facebook automatically tells me "No Internet connection," Opera won't load pages, Google Talk can't sign in, etc. If I turn mobile data back on, things work again, albeit slowly.
The strange thing is if I turn on Airplane Mode and then turn it off, leaving data off, my wifi will work 100% normally. If I try to turn on mobile data again, I get the same issue.
While I was away, I replaced the SIM card so I could use my phone over there. I messed with some APN stuff thinking I would be able to get data on my phone in Korea, but that didn't work out so I returned my APN settings to default. I have a feeling that's the source of my problems, but I have no idea how to fix it. I tried restoring my APN settings to default through the settings, but that didn't fix it either.
Any help at all would be appreciated!
If it helps I have been seeing the same thing. I'm on CleanRom 3.5 (Verizon Rom base) and PB&J kernel. It seems to be hunting between them even when in strong wifi signal.
Interestingly enough it's not doing it right now.
I'll keep a closer eye on it now.
Sent from my SCH-I605 using xda premium
In my case, it's a constant problem (unless I manually go into airplane mode, like explained). It doesn't work sometimes and not work other times.
I'm trying to use wifi at home, so signal strength isn't an issue either.

[Q] Mobile data not working after WiFi signal lost

Hi all,
bought for my wife Padfone S but when she leaves home WiFi, data does not automatically turn on.
If I turn off WiFi manually, data gets connected automatically, but if she just leave the range of WiFi with WiFi still on, but out of reach, the phone doesn't connect to 3G even if I'll turn WiFi off & on, data on & off - only what helps is restart of the phone - then connects to the mobile data without problem.
Phone is new, not rooted, stock ROM.
Shall I send to service?
Thanks for any tips.

My girlfriend and i both have this phone, her's had the same problem in one of the first software versions. Then a restart would help, but after the latest updates this problem doesn't occur anymore.

What software version you have?
I've bought the phone in East Asia and can't update any more. But played with the APN settings & actually it helped - the default settings was strange and now it works.
