The SMS notification behavior is inconsistent on the Samsung Galaxy S2 after upgrading to 4.0.3 ICS. When receiving a text message, the phone does not make a sound or vibrate, regardless of the notification settings, and regardless of the sms app used (including the default). The screen will turn on. This problem will go away after rebooting, but then it will return after time. This is a problem that has been discussed in several forums.
Is there a fix for this? I'm open to rooting my phone. I have already done a factory reset since upgrading from Gingerbread to ICS.
