  So, that you have complete information about your smartphone and you can take additional steps to fix it. There are several ways to assess the overall health of your device, from internal menus accessible with secret codes to apps capable of complete hardware and software analysis.

  Methods for performing a complete diagnosis on Android

  In the Android universe, users have two main ways to diagnose the mobile: Using hidden codes that enable advanced options or using applications that provide comprehensive hardware and software reports.

  These codes are primarily used for technical testing by support services and provide options for checking various hardware components.

  Preliminary considerations on secret codes

  • Each manufacturer may use different codes.Some codes may not be compatible with your model. Just install it, accept the permissions, and choose a Quick test or complete analysis, which includes up to nineteen tests such as touching the screen, checking the accelerometer, testing microphones, cameras or proximity sensors.

    In addition, TestM offers additional options such as checking the device's technical information, quick access to the IMEI, internet speed test, detailed battery information, and the ability to locate nearby repair shops in case of a fault.

    AIDA64

    AIDA64 It is a veteran application that offers advanced information on hardware and software for Android.

  Helpful tips for using diagnostic codes and apps on Android

  Hardware diagnostics are very useful, but you always have to take some precautions:

  • Do your research before using any secret code: Not all codes perform harmless tests; some can reset data or activate dangerous functions.
  • Do not change advanced settings without knowing: In engineer mode or internal menus, changing parameters without knowledge can negatively affect the phone.
  • Always use apps from trusted sources: Download from Google Play and check out other users' reviews before installing any diagnostic app.

  When you finish a diagnosis, the results may be:

  • All components are OK: Perfect, your phone is healthy!
  • A component fails or gives strange results: For example, the touchscreen is unresponsive, the battery is in poor condition, or the proximity sensor is not working.

  What to do if you find a fault?

  • Simple solution search: If it's software, try restarting, updating, or resetting to factory settings.
  • Replacement or repair: If it's a physical fault and the phone is under warranty, contact an authorized service center.

    It's also ideal if you want to know all the technical details of your phone, as it detects the CPU frequency in real time, displays information about the GPU, Wi-Fi networks, and even the apps installed on the system. Another reliable alternative is to use an external app or tools like Phonecheck.

    • Sensors: gyroscope, accelerometer, light sensor, proximity sensor, digital compass.
    • Network and connectivity: WiFi status, Bluetooth, 4G/5G, network signal and speed, GPS, NFC.
    • Audio: speakers, microphones, volume buttons, connectors and headphones.
