Hi. i noticed something strange. i only wish i could pinpoint when this behavior resurfaced. A few versions of IOS ago, Voice over would take a long time to click off, after it was done speaking. You would only notice this if your ear were next to the speaker, say if it were lying on your pillow. Well in a subsequent version this wait time for lack of a better description was drastically reduced. Until now with IOS13, i noticed that it took i'd say a full two minutes after i stopped interacting with the screen. Let me give you an example. The screen is set to autolock in one minute, and you've just finished swiping over an app and just wait. You will hear "screen dimmed", then the chirp when the phone locks itself. Then if you are very quiet, you will hear the hiss of the internal speaker for as i said about another minute. i didn't count so i could be off, but I know this wasn't happening in a previous version of IOS By no means is this something to be worried about, I just happened to notice so I thought I'd see if anyone else did.
