I've just switched from a Sony Xperia Z3 (6.0) to the Samsung Galaxy S8. On the Sony I could set Do Not Disturb mode for a specific time (15 mins, 30 mins, an hour, 2 hours and so on) using the Quick Settings menu.
This was a really useful feature when going into meetings, presentations, movies etc. But I can't find this feature on the S8 - there's only the option to enable DND mode (and leave it on) or schedule it between specific times.
Is there anyway to get the great 'DND for 15/30/60 etc. minutes' feature in the Quick Settings on the S8?
