How To Fix Screen Does Not Turn Off / On During Calls on Galaxy S23 Ultra

If your Galaxy S23 Ultra screen does not turn off or on during calls, there are a few things you can try to fix the problem. Here are some solutions to choose from:

1. Restart your phone. A simple restart can often fix minor software glitches that may be causing the problem.
2. Check your proximity sensor. The proximity sensor is responsible for turning off the screen when you hold the phone to your ear during a call. If the proximity sensor is not working properly, the screen will not turn off. To test the proximity sensor, go to Settings > Battery and device care > Diagnostics > Phone diagnostics and tap Sensors. 
3. Update your phone’s software. Samsung regularly releases software updates that include bug fixes and performance improvements. Make sure that your phone’s software is up to date to see if that fixes the problem.
4. Reset your phone’s settings. This can sometimes fix screen problems caused by incorrect settings. To reset your phone’s settings, go to Settings > General > Reset > Reset settings.
5. Perform a factory reset. A factory reset will erase all of the data on your phone and restore it to factory default settings. This should be a last resort, but it can sometimes fix screen problems that other solutions cannot. To perform a factory reset, go to Settings > General > Reset > Factory data reset.

Additional tips:

• Avoid using cases or screen protectors that cover the proximity sensor.
• Make sure that your phone’s screen is clean and free of fingerprints.
• Try using a different earpiece.

If you have tried all of the above solutions and the problem persists, contact Samsung support for further assistance.
