I use the Samsung calendar, I only have my 2 Gmail calendars synced and content is not hidden on the lock screen. I've tested this by adding events for 5 minute , after the 5 minutes is up the event disappears. Upon doing research there are many other with the same issue and it's been identified as either the Google pie update or the Samsung update which makes sense, as my old note was never updated and I didn't have this problem. I've checked all settings, there is nowhere to change this, it just happens with no way to prevent it. I've also noticed my phone no longer syncs calendar events over around a year ago, although they are visible on a desktop on the Google calendar. As far as the alarms go, there are no settings available anywhere in the factory clock app. I've included screenshots of this. The only volume setting is the volume of the ringtone, but no gradual increase option.
