Sometimes a creeper doesn't make the hissing sound when it walks up behind you before it explodes. I know this has existed for a while, at least dating back to 1.13.

@unknown Please make a report on the MCPE project if you're experiencing the same issue there. Make sure to search before reporting however as your issue may have already been reported by another user.
On Bedrock 1.16 PS4 this bug still exists. Twice so far I've been killed with no warning before the explosion.
