tushar1204, Jan 12, 2019 : Hi, I am not able to customize my Do Not Disturb Section's Exceptions. Whenever I go to Settings>Sound> Do Not Disturb> Exceptions, I am not able to customize the Calls & Messages, events and reminders Section. Whenever these two menu options are being selected, the Settings app crashes. When restored to factory settings, it works again, however, if back up is restored, it again fails. What's the root cause of this? Any tentative solution?
