There are no hidden sectors. If a MBR is used, the partition boot sector can be found at the sector address specified in the partition table. The point has been discussed in detail up in this thread.

I reject a SD card from my cellphone it has 153 hidden sector and after a while that I was reading and writing on it through MCU , it's hidden sector has changed to zero !!!!!!! how do you explain it ?
 

Hello!

I reject a SD card from my cellphone

What do you mean?

it has 153 hidden sector

Once again, there are no hidden sectors on an SD card. There are reserved sectors as specified
by the FAT specs, but no hidden.

and after a while that I was reading and writing on it through MCU ,
it's hidden sector has changed to zero !!!!!!! how do you explain it ?

The SD card does not write itself. If one sector changed, it's simply because you wrote it at some point.
