iPad Air 4th Generation (Model A2072) was dropped onto tiled flooring. The top-right aluminum corner is bent inward against the glass, causing extensive diagonal cracks across the display. The top power button is slightly wedged in the bent frame. Seeking confirmation on whether the screen is laminated and whether Touch ID functionality can be preserved.

iPad Air 4 uses a fully laminated 10.9-inch Liquid Retina display where glass, digitizer, and LCD are fused as a single assembly. The top power button houses the cryptographically paired Touch ID sensor. The bent aluminum corner must be reshaped using specialized corner milling tools to relieve pressure and prevent the new glass from cracking upon installation.
1Do not pry against the wedged power button with knives or screwdrivers, which tears the delicate Touch ID sensor flex ribbon.
2Reshape the deformed aluminum housing corner using specialized G-Tool hydraulic corner matrices and dental micro-burrs.
3Carefully heat and release the original Touch ID power button module, preserving the original ribbon cable and seating it securely into the reshaped frame.
4Install an OEM-grade laminated Liquid Retina screen assembly and cure under regulated spring clamp pressure for 2 hours.
Parts Standard: OEM-grade laminated Liquid Retina display assembly with wide color gamut (P3), True Tone support, and Apple Pencil 2 latency response.
Workshop Turnaround: 3 to 4 hours bench service including regulated clamp cure time at St Marys workshop

Dented aluminum corners are the most frequent challenge with dropped iPads. If a shop forces new glass into a bent corner without milling, the screen will crack within days from chassis tension. We reform the aluminum corner precisely and transfer the factory Touch ID button so biometric security is preserved.
