Google calendar event reminder sound is too short and I can't hear it One of main google's calendar functions is to remind people their events, with a scheduled sound alarm. The problem is that this sound, I know how to change it, but it only lasts for 1 second, so I don't hear it. Instead, when they call me, the sound lasts for very long until they hang up the phone, so I realize I'm being called. I would like if the alarm sound lasted longer, how to do it?

By the way, I have the same problem with google keep reminders.

I imagine some people like short sounds because they don't want to get disturbed, and probably they get reminded when they check their phones and see the notification. I want to know if it's possible to make it work like I specified, a longer loud sound like a call.
Go to "My Files" and then copy any mp3 or sounds that sounds longer to be your reminder. Then go to "device storage" look for "notifications" folder and paste it there.

Now go to your S Planner and go to "Settings" now you'll see your mp3 as the choice in the notifications tone options. Now you'll have a longer reminder tone 
Hope this will help
