Iphone SE ios 15.7.5 "clock" tile does not respond

Hello phil1131,

Thanks for that info and for choosing the Apple Support Communities. If we understand correctly, you are having an issue with the Clock widget on your iPhone. A good first step to isolate this is to remove the widget:

"Remove a widget from the Home Screen

1. Touch and hold the widget to open the quick actions menu.

2. Tap Remove Widget (or Remove Stack), then tap Remove."

Then restart your iPhone: Restart your iPhone - Apple Support

Then add the Clock widget again:

"Add a widget to your Home Screen

1. Go to the Home Screen page where you want to add the widget, then touch and hold the Home Screen background until the apps begin to jiggle.

2. Tap  at the top of the screen to open the widget gallery.

3. Scroll or search to find the widget you want, tap it, then swipe left and right through the size options.

4. The different sizes display different information.

5. When you see the size you want, tap Add Widget.

6. While the apps are still jiggling, move the widget where you want it on the screen, then tap Done.

Tip: A Smart Stack (with dots next to it) is a set of widgets that uses information such as the time, your location, and activity to automatically display the most relevant widget at the appropriate time in your day. You can add a Smart Stack to the Home Screen, then swipe through it to see the widgets it contains."

And those widget steps are from here: Add widgets on iPhone - Apple Support

If you are still having an issue after following those steps, please contact Apple directly for further investigation: Get Support

Cheers!
