data connection droped after 4.1.2 update

After updating (OTA) to 4.1.2 mobile data connections started to drop a lot.
Basically it works fine after a reset and most times after switching airplane mode on and off.
When keeping data connection active, there is no problem either.
However, after some idle time the connection is switched off doesnt get on again.
Even if I turn off/on the mobile data connection option.
Most of the time I would have to reset the phone.
This was fine before the update. (4.1.1)
Is anyone experiencing anything like this?

[Q] Force 3G on before leaving WIFI out

Hi,
You probably already noticed that by your self..
When you're downloading something over 3G, and you turn the WIFI on during the process, there is no problem because it authenticates and connects the WIFI network and meanwhile keeps the 3G still alive.. it only shuts it off when the WIFI is completely connected and therefore the download is not hanging off..
Unfortunately it was not programmed backward.
When you are on WIFI and turning off the WIFI to move to 3G, or perhaps when you were at home and now walking away the range and so it automatically disconnects it, so it leaves the WIFI first and few seconds later it trigger the 3G and connect it..
During those few seconds you lose the connection and if you were on downloading process it hangs off..
So I was thinking, why not force the 3G on, connects, and only then, hang off the WIFI..
Any app that can do that? or any developer that might wanna pick up the glove?
I'm sure it will help few others but me..
Thanks ahead!

Wifi Issues After 4.3 Update......

I was reluctant to do the update to 4.3 but decided to go ahead and give it a whirl. Things went smoothly, and all worked out as planned.
However, I'm now experiencing a constant drop in my wi-fi connectivity.
My employer provides an open wi-fi. The signal strength is a little weak in my office. Before 4.3, I was able to auto connect to the wi-fi and stay connected all day with no issues. Post update, I am constantly having to tell the phone to connect. Even though auto connect is checked. It seems like if the signal strength dips at all.....the phone drops the signal. Then instead of reconnecting, its sits unconnected until I open the wi-fi setting and force it to connect.
Do you guys know of some setting I'm missing or something that keeps this darn thing connected ??

WiFi disconnects randomly though it's turned on.

My wife has a stock G3 and for months we've exceeded our data allocation because her phone will automatically and seemingly randomly switch to mobile data even though WiFi is turned on and she's home. Turning off WiFi and back on again will show that our home WiFi network is saved, but won't connect. Turning on airplane mode and back off again will get the WiFi to reconnect, but that's not something my wife will remember to check and these data overages are getting ridiculous. Is this a known bug, or should we try to get a replacement device?

Maybe check your apps? Some apps ask for permission to turn on and off Wi-Fi to save battery or when your phone percentage goes down to a certain level. Of not that, then get a replacement. This doesn't happen to me

Did she accidentally save any other networks nearby or have you connected to them? I had a low signal WiFi saved at my house. I had to forget the network because it kept trying to switch networks, then dropping completely. When I only had the primary network saved, it suddenly was a strong and stable connection.
I noticed with other devices that they will drop connection when searching for networks and there are too many nearby open networks too.

Data not connecting after WiFi?

Whenever I leave home, and the phone disconnects from WiFi, it fails to establish a data connection, and requires a restart of the phone.
I have tried toggling the data connection and airplane mode in the hopes of resetting the connection but it fails every time. I have also turned on the aggressive transfer in developer options, but this hasn't helped either.
Any ideas?
Same here when I switched to "Prefer 3G" in settings. When switched to "Prefer LTE" everything is back to normal.
