According to a forensics detective, Android encryption has made it harder to crack Android phones as compared to iPhones. This is a reversal from the norm.
Cellebrite — one of the most prominent companies that government agencies hire to crack smartphones — has a cracking tool that can break into any iPhone made up to and including the iPhone X. The tool pulls data such as GPS records, messages, call logs, contacts, and even data from specific apps such as Instagram, Twitter, LinkedIn, etc., all of which could be incredibly helpful in prosecuting criminals.
However, that same Cellebrite cracking tool is much less successful with Android encryption on prominent handsets.
