Hi, I personally encounter a similar issue with my MX4 from the beginning (OTA 8 I think), but upgrade after upgrade it becomes more and more significant. I didn't notice this for Wifi, but for mobile networks (not only 3G). I also didn't pay attention to the sleeping time. But after a long sleep, only SMS are available. I lose the internet connection and I cannot call. Switching the airplane mode off/on re enables the internet connection but I have to reboot to be able to have a phone call. In previous version, it rather occurred when the wake up took place after a move (ie. I get a train to go working) But now it becomes more and more frequent even if I stay in the same place (ie. When I use my phone on the morning). What kind of information do you need to investigate ? Eric

Example: I reboot the MX4 and when it powers up all is working I get WiFi and Mobile Network 3G working great. I press the button to turn off the screen and leave it off for 2 or more minutes, when I turn it back on and unlock the device the Data network is not working. I can make calls and SMS but MMS and Data has no connection, at this point i can toggle the Data switch in the mobile configuration or put the phone into airplane mode and back into active and it works until next time.
