How to test the screen and sensors of a Samsung phone
A cell phone sometimes has a lot of sensors, but some of them are almost never used. Often only a few sensors are used, such as fingerprint, face recognition, iris and proximity.
Have you ever thought about whether the other sensors in the phone are fully functional? For example, sensors for steps, brightness, heart rate and others that are supported by the mobile phone.
On Samsung phones, all supported sensors can be tested on the device a place. This is a great way to tell if the phone is in good condition or not. And it’s not just a sensor that can be tested, it’s screen touch, color and so on.

Sensor test
Menu items SENSOR You can test almost all supported sensors on the phone. Such as accelerometer, brightness, proximity, fingerprint, gyroscope and others.
For example, try putting your hand on the phone’s proximity sensor. Vibration will occur later when the sensor reacts. If you don’t understand the proximity sensor, it is usually used when making a phone call, where the phone will automatically darken the screen when the screen is near your ear.
Camera test
There is also a menu for testing the camera functionality, which is divided between the front camera (FRONT CAMERA) and the rear camera (REAR CAMERA). This is of course to check whether the camera is working properly or vice versa.
An example of an incident where you need to test the functionality of the camera is when you cannot take photos properly. So you can find out if the error is caused by the camera application or even the camera of the cellphone.
