Hello, I have a Samsung Galaxy A12. The icon on the Samsung calendar app doesn't always change so shows wrong date. I sent it back and got a replacement but this one is doing the same. Restarting the phone makes it change. Anyone else had this issue?
@elly39: A weekly view should be available by opening the Calendar app > Tap the 3 lines in the top left > Tap 'Week' towards the top of the pop up window (options should be Year, Month, Week and Day). Let me know how you get on.
