The investigators of the Texas Church mass shooting have stated they cannot unlock the shooter's phone. They are not revealing what make the phone is to avoid promoting the brand of phone.
It no doubt is a modern iPhone. Most Android phones do not ship with built in encryption. . . and there are unlocking tools for those that do. However, Apple can provide the data backed up on the iCloud with an appropriately structured search warrant, which it did for the San Bernardino terrorists, and would have been able to unlock the terrorists' iPhone had the FBI not CHANGED the use's AppleID before checking with Apple for advice. That succeeded in permanently locking it. The data the 3rd party got was extremely limited.
