Touch Screen NOT working Apple Watch 9

The first (and simplest) thing to try if something isn’t working right is to restart your Apple Watch and its paired iPhone. If necessary (device not responding), try a forced restart. Both methods can be found here:

Restart your iPhone - Apple Support

If that doesn't help, the next steps would be to unpair and pair your watch again and restore from the backup just created. This should result in no loss of data. It deletes all temp and corrupted files and re-indexes the file system.

As a last resort, follow the above procedure for unpairing and pairing the watch, but do not restore the backup. Set the watch up as new instead. There should be no loss of Fitness data or Awards since those are stored on the paired iPhone, not the watch.

If none of the above helps, there may be a hardware problem with the watch.

If you still need help, contact Apple Support.

If the Watch touch screen is not responding, and the water (screen) lock is not set, you’re headed for repair or replacement.

You’re still headed for diagnostics and potentially a repair, given all of what you’ve already tried.
