Since the update from yesterday, it seems that the contacts from my Sim card aren't recognized any more in the Phone and SMS app. I double checked the sim card's content with the SIM Card Manager app and they are all there.
So why doesn't the SMS and Phone app recognize them? When I choose 'Show contacts > Sim Card' it shows 0 contacts, which should be more, because as mentioned earlier they are still on the sim card.
I'm using a Medion P4013, which is using Android 4.0.4
