Understanding the Possible Causes
Before we dive into the solutions, it’s essential to understand the possible causes of this issue. Here are some of the most common reasons why your Galaxy S8 screen might be turning off:

Q: Why does my Galaxy S8 screen keep turning off?
The Galaxy S8 screen may keep turning off due to various reasons such as a faulty proximity sensor, screen timeout settings, or a software glitch. The proximity sensor is responsible for detecting when your phone is in close proximity to your ear or face, and it may cause the screen to turn off if it’s malfunctioning. Additionally, if the screen timeout settings are set too low, the screen may turn off frequently.
Other possible causes include a software issue or a third-party app interfering with the screen’s functionality. It’s also possible that the screen is turning off due to a hardware problem, such as a faulty screen or a loose connection. To troubleshoot the issue, try adjusting the screen timeout settings, cleaning the proximity sensor, or restarting your phone in safe mode.
Q: How do I adjust the screen timeout settings on my Galaxy S8?
To adjust the screen timeout settings on your Galaxy S8, go to Settings > Display > Screen timeout. From there, you can select the desired screen timeout duration, ranging from 15 seconds to 10 minutes. You can also set the screen to stay on while the phone is charging or when you’re using certain apps.
Additionally, you can also adjust the screen timeout settings while the phone is in a specific mode, such as when it’s in a car dock or when it’s connected to a Wi-Fi network. To do this, go to Settings > Advanced features > Screen timeout, and select the desired mode. You can also set the screen to turn off automatically when you’re not using it by enabling the “Auto-lock” feature.
Q: How do I clean the proximity sensor on my Galaxy S8?
To clean the proximity sensor on your Galaxy S8, start by locating the sensor, which is usually located near the front camera lens. Use a soft cloth and gently wipe the area around the sensor to remove any dirt or debris. Avoid using harsh chemicals or abrasive materials that may damage the sensor.
Once you’ve cleaned the sensor, restart your phone and test the screen to see if it’s still turning off frequently. If the issue persists, try calibrating the proximity sensor by going to Settings > Advanced features > Proximity sensor calibration. Follow the on-screen instructions to complete the calibration process.
Q: What is safe mode, and how do I restart my Galaxy S8 in safe mode?
Safe mode is a diagnostic mode that disables all third-party apps and services, allowing you to troubleshoot issues with your phone.

Immediately release the Power button and hold the Volume down button. Keep holding the Volume down button until the phone boots up in safe mode. You’ll see “Safe mode” displayed on the screen. In safe mode, test the screen to see if it’s still turning off frequently. If the issue is resolved, it may indicate that a third-party app is causing the problem.

To disable adaptive brightness on your Galaxy S8, go to Settings > Display > Adaptive brightness. Toggle the switch to the “Off” position to disable the feature.
