Test Samsung phone hardware with Secret Codes
SAMSUNG PHONE HARDWARE CHECK GUIDE
Step 1: On your Samsung phone, go to Phone -> Keypad and enter *#0*# to access the Samsung hardware test mode using a code.
Step 2: Your phone screen switches to hardware test mode. This mode features numerous Samsung hardware testing functions. Focus on the essential hardware test features.
Step 3: Tap on the Red, Green, Blue features sequentially to check for dead pixels on your phone's screen. Your screen will switch through Red, Green, and Blue modes, allowing you to inspect for any dead pixels.
Step 4: Check your Samsung's hardware functionality, specifically the hard drive's performance, within the Dimming section to test backlight brightness.
Step 5: Use Mega cam and Front cam to test the rear and front cameras of your Samsung phone. Apply features like Zoom and video recording in different resolutions to ensure the captured images meet your standards.
Step 6: Test phone sensors in the Sensor section. This hardware test via code reveals accelerometer, sensor, compass functionality, etc. Rotate and move your device to check if the indicators are functioning properly. A non-responsive indicator suggests a malfunction in one of these features.
Step 7: In the Speaker section, a music piece with gradually increasing volume is played to test speaker quality. Meanwhile, the Receiver section requires you to listen through the earpiece (internal speaker) to verify the call receiving speaker's functionality.
Step 8: Tapping on Vibration triggers continuous phone vibration to test vibration intensity. For external button (physical button) testing, select Sub key and press Home, multitask, back, volume up/down, and power buttons to check for any stuck buttons on your Samsung phone.
Completing all 8 steps of the Samsung hardware test using secret codes indicates your device is still in good working condition. For a more comprehensive hardware check, consider using the CPU Z for Android app or the developer-favored PhoneINFO+ app for detailed inspections like hard drive status, manufacturing date, root status, and more on Samsung and other phone brands.
