iPhone Diagnostics is a suite of tests that examine your iPhone's hardware components. It covers a wide range of functionalities, including:

• Touchscreen

Types of Diagnostic Tests

iPhone Diagnostics offers two types of tests:

• Sequential Tests: These tests run a series of comprehensive checks on multiple hardware components simultaneously.

Interpreting Test Results

After running a diagnostic test, you will see a report with the results. The report will indicate whether each component passed the test or failed. If a component fails, it means that there may be an issue with that particular hardware component.
