CEIR Zimbabwe’s cell phone diagnostics are tests that check the hardware and software health of a smartphone, covering components like the display, battery, camera, sensors, and connectivity. These tests help identify issues and can be used for performance analysis or when buying a used device. Diagnostic tests involve a constructive examination of a mobile phone’s overall working condition or functionality using software tools. The test checks how well different parts of the smartphone perform and can help you detect problems in its functionality.

A diagnostic test encompasses a deep analysis of the device’s different software and hardware features, including the performance of its processors. Important phone features like the battery, speakers, microphone, haptic feedback, sensors, camera, wi-fi connectivity, screen pixels, etc., are adequately examined during the test.

Diagnostic tests can also help you check whether the smartphone has a clean ESN (unlocked) or a bad ESN (locked or blacklisted). Furthermore, it can help you identify SIM locks, mobile device management locks, cloud locks, etc.
