Internet and MMS services stop working after an hour of restart
After I upgraded my Sony Xperia S to Android 4.0.4 after an hour or so of not using my phone and/or when I leave a WIFI area I cannot use any data services on my phone from my network without restarting the device. I can reconnect to WIFI again without a problem.
I've tried resetting the phone, checking the power saving settings and reinstalled my network providers MMS and 3G settings.
Any idea guys and thanks in advance.
