Where is the GPS chip located?

Hello, I want to know where the GPS chip is located on the A51 (4G version). Indeed, after changing the screen unit, my GPS no longer works. Having damaged a sheet of the intermediate frame during the operation, I thought it came from there. So I changed the intermediate frame, but the problem persists. So I would like to know the situation of the GPS chip, to be able to change it. Thanks in advance,

Regards.
