A friend of mine was recently questioned by the FBI in regards to a potential crime that his employer allegedly committed (I can't go into the details). They asked him to give them his phone and unlock it. He asked them what if he didn't want to unlock it. They told him they would hold him down and use his biometrics to open it. As soon as he told me this story I disabled biometric unlock on my phone. It's really not that much of an inconvenience. I can still use my fingerprint to login to banking apps and stuff, it's not that big of an adjustment to put in my code every time I have to unlock my phone.
