Just updated my Samsung S7 to Android 7.0 but TouchWiz Home crashes non stop. Help please.

[AC Question]

I just updated my Samsung Galaxy S7 to Android 7.0
My phone now has no home screen and I can't access any apps. All I can do is access apps that appear in the notifications bar. I've tried to clear TouchWiz data and restart the app however it's not listed under All Apps in Application Management. The new update must have removed it. I've tired a partition cache wipe and still no luck. Any help would be great.

Samsung has rebranded Touchwiz to 'Samsung Experience' starting with Nougat so take a look in your Apps menu/ALL. Try doing 'Force stop' and then 'Clear data' of the app and then reboot your S7 and see if things are working normally again.
