The history? In order for the history to save something you need to hit =

For example
1+1 you will see the answer 2 but it will not make a history about it
1+1 and you hit = it'll just show 2, but it will create a history of you hitting 1+1 and the answer 2.

@userRjLnuywOrw This happens after you clear history of the calculator. The clock (history) icon will appear once again after you complete a transaction on the calculator.
