No apologies necessary. We are all inept when we do something for the first time.
Power off your phone.
Press and hold down the following 3 keys simultaneously. Volume up, Power and Home.
Keep holding the keys down till you see a bright blue line of words (power rebooting) on the top of your screen.
Let go of the keys.
Be patient in all the remaining steps.
You will then see a circle with the words ' installing update' followed by a fairly reasonable period where you will see the android dummy lying flat and the words 'no command' on the screen. Be patient.
The screen will now change with lines in gold followed by lines in blue. The top Blue Line will be highlighted with a blue background 'Reboot system now '. Be careful now.
Use the lower volume key to move the highlighted line down to 'Wipe cache partition'.
Once this is highlighted press the power key.
The window will change offering you 'No' and 'yes' options. Use the lower volume key to highlight 'yes' and then press the power key.
The window will change with 'Reboot system now' highlighted. Press the power key.
Your Samsung will now reboot with the system cache cleared.

Will this fix the dynamic calendar icon as well? It worked with 6.0. I use nova launcher and stealth icon pack
