Phone Screen Goes Black During Calls? It's a Feature, Not a Flaw!

• Your phone screen turning black during calls or automatically is a smart feature, not a defect, known to 90% of users.
• Two main reasons: Screen Timeout (saves battery after inactivity) and Proximity Sensor (turns off screen when held to ear during calls).
• These features prevent accidental touches, save battery, and reduce overheating.
• Screen Timeout settings can be adjusted in Display/Screen & Brightness; power-saving mode can reduce it.
• If the proximity sensor malfunctions, clean it or check for obstructions like screen protectors; persistent issues may require a service center.
