GUIDE
1. Choose one ordinary control, such as opening Settings. Record whether missed touches occur across apps or in only one app before changing anything.

2. Check the screen is dry and clear of surface debris. Do not press on cracked glass or a separating display.
Sources: https://support.apple.com/en-us/102567; Screen clean and free of debris or water
3. Disconnect Lightning accessories. Repeat the same action; a cable-dependent improvement belongs in the accessory comparison.

4. Remove only a safely removable case or protector, then repeat. If removal would disturb broken glass, stop and seek service.

5. If touch permits, hold either volume button with Side, use the power-off slider and wait 30 seconds, then hold Side to start. Compare the same action after restart.

STOP CONDITIONS
Stop using and charging equipment with swelling, casing separation, smoke, a burning smell or suspected battery damage. Do not open or press on it.
Set damaged accessories aside. Do not open mains adapters or force connectors.
Do not erase, reset, flash firmware or bypass a lock as a default diagnostic step.

OUTCOMES
Comparison recorded: Save the condition that improved touch and repeat only during normal use. Keep any implicated charging accessory out of use pending its own checks.
- Same control tested in each condition
- Whether disconnection or covering removal changed response
- Single-app versus system-wide touch failure
Complete the missing preparation: Complete a safe dry-screen and disconnected-accessory comparison before interpreting touch.
- Use a safe intact screen and an ordinary non-sensitive control.
- Same control tested in each condition
- Whether disconnection or covering removal changed response
- Single-app versus system-wide touch failure
Discuss the recorded result with support: Ask Apple to review persistent touch failure with the exact app/control and accessory conditions.
- Same control tested in each condition
- Whether disconnection or covering removal changed response
- Single-app versus system-wide touch failure
Keep the unknowns in your handoff: The covering or restart condition was unavailable; that comparison remains unknown.
- State whether the uncovered or unplugged comparison was skipped and why it was unsafe or unavailable.
- Same control tested in each condition
- Whether disconnection or covering removal changed response
- Single-app versus system-wide touch failure
Stop powered checks: Stop using or charging damaged equipment. Do not open or press on the phone or handle hot or smoking equipment. Contact Apple or an authorized provider; use local emergency help for immediate fire danger.
- Tell the provider about lifted or cracked glass; do not press it back into place.
- Same control tested in each condition
- Whether disconnection or covering removal changed response
- Single-app versus system-wide touch failure
