Restart your iPhone, iPad, or iPod touch - Apple Support
If a force restart doesn't help : Backup your data, then Use iTunes on your Mac or PC to restore your iPhone, iPad, or iPod to factory settings - Apple Support. After that, set up the device as new (not using the backup). Test the device. If it still presents the issue, it's a hardware issue. You can go to https://getsupport.apple.com/ and to learn which service options are available in your country.

Have not done a re-set yet, but a local phonr repairer that I trust has said that it is a hardware issue, and the screen needs replacing; cost is £40 (GBP), which is a reasonable price over here. Will probably do this.
