From more than 50% of all mobile devices investigated by the FBI from October 2016 till September 2017, could no data be retrieved due to the encryption. FBI Director Christopher Wray admitted during a police conference in Philadelphia that more than 6900 devices couldn’t be accessed.

And where are the warrants to verify this?
