The iPhone SE of 2022, the third generation, has a 4.7 inch Retina display with a Touch ID home button, and when its touch screen is unresponsive, jumpy or registers touches that are not there, the cause is usually water, a screen protector, software or damage, and the SE's small size and long life make age-related faults worth considering. Begin by cleaning and drying the screen with a soft cloth, because moisture, sweat and grease confuse the touch layer; wet fingers and a damp screen produce ghost touches.
The checks in more detail
Take off a thick or cracked protector, which is a common cause of laggy or uneven touch, and see whether the response improves. Remove a case that presses on the edges of the display. Restart the phone by pressing and releasing Volume Up, then Volume Down, and holding the side button until the Apple logo appears. If the problem continues, look at the software. Update iOS in Settings, General, Software Update, because touch bugs are fixed in updates. Check Settings, Accessibility, Touch, for settings that change how the screen responds, such as Touch Accommodations and AssistiveTouch, which can make the phone respond oddly if turned on by mistake.
Test in Safe-like conditions by closing all apps and testing in the Settings app and then a game; a fault in one app only points to that app. Charging while using the phone can add electrical noise that causes ghost touches, so test off the charger, and try a different charger, because a poor one can cause erratic touch. The SE 3 is a small phone, and a drop can damage the display or its connector even if the glass is not cracked.
A touch problem that follows a drop, that affects a band of the screen or that does not change after a restart and an update points to hardware, and a screen replacement through Apple or an authorized provider is the fix. A swollen battery can push the display, so look for a screen lifting at the edges and stop using the phone if so. Back up the iPhone before service. Contact Apple Support with the serial number if the touch problem persists after the steps above.
