I have a problem

My cellphone is Meizu M6

when I got an incoming call, the caller's cellphone number was clearly ringing, and I lifted up and talked to the caller and when it was really important, accidentally and right in the middle of the conversation, I pressed the power button until the cellphone restarted itself

I cried in my heart, right when it was important, the call was interrupted because of this

I tried to check the call log .. Oh no ... danger ... it was zero
there are only history of calls from the previous ones


please help from the masters here
can anyone help me how to see the caller's number?

thanks before
