CQATest (Certified Quality Assurance Test) is Motorola’s proprietary hardware diagnostic environment. When executed, it launches a matrix of manual and automatic system checks. You can individually test the digitizer responsiveness, individual microphone arrays, front and rear cameras, physical volume buttons, proximity sensors, and the integrated stylus pen detection mechanism. It is the best tool to use if you suspect a hardware component is failing. System Configuration and Regulatory Codes

How to Use Secret Codes on MOTOROLA Moto G Stylus Secret codes—also known as MMI, USSD, or Android dialer codes—are hidden sequences of numbers and symbols that unlock deep diagnostic menus, device information, and configuration settings on your MOTOROLA Moto G Stylus. Engineers and technicians use these commands to test hardware components and troubleshoot system errors. Using secret codes on your is like finding
The hidden codes for the Motorola Moto G Stylus open up a world of technical tools, but they are best used with a sense of caution. They are most valuable for checking device authenticity via the IMEI code, running hardware tests on a second-hand phone, and performing simple battery or signal checks. However, it is highly recommended that the general user avoids reset codes or any menu with "engineering" settings, as changing the wrong value could cause performance issues.
Use only for signal troubleshooting; changes may disconnect service.
