I have an issue with my 5. I'll try to tell it as best as I can:
I can only have my phone at my mom's (my parents are divorced), and my first order of business when picking up my phone after arriving for the weekend is clear my notifications.
I open the notification center and switch to the Notifications tab. I tap the "Clear" button and the notifications from that day are removed.
I continue to spam the Clear button and at one point it seems as though it altogether stops responding. It then proceeds to delete my notifications, which would be fine if not for the issue where it shows notifications for a split second before showing the next one, only to delete that one as well (rinse and repeat).
Does anyone know if this has been fixed in Beta 4? At the time of posting this I don't have access to my phone, so yeah.
EDIT: Whoops, didn't add in the information:
Model: 32-Gigabyte iPhone 5
iOS version: iOS 9.3 4th Public Beta
