I have an issue (which has been reduced following a setup as new but still persists) with replying to messages from my lock screen. Not sure if it's common but my message will dismiss even though at this point I'm POSITIVE I'm only hitting the keys on keyboard. I'll be in the middle of composing a reply from the lock screen or a non message app and the message vanishes as if I've tapped blank space to return to the lock screen/app I was using at the time the message arrived. Has anyone else seen this? I'm on a 6S Plus and have tried everything I can think of - reset all settings, set up as new without a restore from backup.
