Someone had problem with this security patch(A415FXXU1CUH2)? Problems with IMEI empty and my sim card that can't be read?
On official security update / software update via your phones software update section wouldn't clear the phones imei.
I would suggest to reach out to a Samsung Service Centre for support.
