Scope and common interpretation errors
For external electronic-device covers, without changing the device's existing safety or protection claims.
Opening stretch, camera-hole location and sidewall thickness affect the key zone. Local internal projections or grip deformation may continuously press a button.

Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Check installed geometry | Compare free and installed holes, sidewalls and key clearance. |
| 2 · Check resting preload | Observe button travel and system state without intentional operation. |
| 3 · Include grip conditions | Test agreed handheld, side-squeeze and pocket-compression scenarios rather than only a unit resting on a desk. |
A comparison to avoid misinterpretation
If the installed button rests near actuation, investigate thickness and stretched positioning before asking software to ignore unintended inputs.

Frequently asked question
Does enlarging the button opening finish the correction?
Also assess feel, protection and edge durability.
