App Store 2.4 rejection: Hardware compatibility

The reviewer may be using a device you didn’t test. Apple’s 2.4 groups several hardware concerns together, so start with the exact subrule, device model, and operating-system version in the notice.

Reproduce the device conditions

Try the submitted build on the reported device or a matching test configuration. Check layout, touch targets, memory use, battery behavior, and any instruction to change a system setting. We’d separate an iPad layout bug from excessive background work; they need different fixes.

For mobile apps, the relevant pages below cover iPad compatibility, resource use, and unnecessary device changes. Apple also has TV- and Mac-specific rules, which this phone-and-tablet library excludes.

Verify the actual correction

Repair the layout or resource use in the build, or remove an unrelated setting requirement. Test the corrected flow on the affected device and on the phone configuration you originally used.

Include the tested device, OS, and steps in your reply. A compatibility claim in the description isn’t evidence that the reviewer can complete the task.
