Let's delve into various ways to check Samsung devices, including testing Samsung phones. In this article, we continue exploring checking and testing Samsung hardware using specific codes.
Checking Samsung Phone Hardware with Unlock Codes
To perform hardware checks on Samsung using codes, follow these steps:
Step 1: From the Samsung phone's home screen, access the Phone app as shown below. On this dialing interface, initiate the process of checking Samsung phone hardware using codes.
Step 2: Next, input the code *#0*# as shown below. Instantly, the system will transition us to a menu to perform hardware checks on the Samsung phone.
Now, we will proceed with the steps to check Samsung hardware as follows:
1. Check Samsung Screen
To perform the Samsung screen check, we can choose various options as shown below.
Instantly, the screen system will display the corresponding color you selected to examine if the screen reflects the correct color. Most importantly, carefully check for any dead pixels on the screen.
2. Check Screen Backlight
Next, we will examine the screen backlight by selecting the Dimming option.
If the device displays brightness appropriately for real-world conditions, the product is normal.
3. Check Camera
For Mega Camera (main camera) and Front Camera, these options allow you to inspect the device's cameras.
To assess the camera's photo-taking capabilities, move the camera, change its position from near to far relative to a specific object. Observe if the camera focuses well, captures accurate colors, and check for any camera issues like vibration, blurriness, or distortions.
4. Check External Speaker
Select the Speaker option to examine the speaker component on your phone.
The system will play a piece of music for you to assess the condition of the external speaker on the phone. Check for stability, distortion, or any audio issues.
- Additionally, with the Receiver option, you can test the external speaker on the phone.
5. Check Touchscreen
Similar to checking the Samsung screen above, testing the Touchscreen will inform you of its functionality.
Specifically, swipe the screen along the edges and various areas. When you draw a blank space, it should not display green at the drawn location.
6. Check Accelerometer, Gyroscope, and Compass
Select the Sensor option to test these features. If the device runs through the items to measure sensors, compass, etc., as shown below.
If all these items work, the sensor component on your Samsung is stable. Conversely, if any item fails, it indicates an issue with the sensor component.
7. Check Physical Buttons
The Sub Key option allows you to test all physical buttons on the Samsung phone for stable functionality.
Press each physical button such as volume up, volume down, power, home, back, and tasks to test. If pressing a button doesn't change the screen color, it means there is an issue with that button on the phone.
8. Check Vibration
Select the Vibration option to test the vibration component on your device.
At this point, your device will vibrate as a notification. If the screen goes black and vibrates, this feature is functioning well.
So, we have just explored the quick and convenient steps to check Samsung phone hardware using codes. This allows you to view the Samsung configuration without the need for any supporting applications or devices.
