Common Redmi 3S Call Screen Problems

Understanding the symptoms is the first step toward a solution. Here’s what users typically encounter:

1. Black Screen During Calls

The proximity sensor may malfunction, causing the display to remain off even after ending a call.

2. Unresponsive Touchscreen

The screen fails to register taps or swipes while on a call, forcing users to restart the device.

3. Flickering or Gray Bars

Visual artifacts appear during calls, often linked to software glitches or hardware degradation.

4. Call Screen Freezes

The interface becomes unresponsive, requiring a force reboot.

Hardware-Related Causes and Fixes

Physical components often trigger call screen issues. Here’s how to diagnose and resolve them:

1. Proximity Sensor Calibration

Issue: Dust or misalignment disrupts the sensor.
Fix: Use a soft brush to clean the area above the screen. If unresolved, enable sensor calibration in developer settings.

2. Damaged Display Cable

Issue: Loose or frayed cables inside the device.
Fix: Non-technical users should seek professional repair. Avoid DIY fixes to prevent voiding warranties.

3. Faulty Digitizer

Issue: The touch layer deteriorates over time.
Fix: Replace the screen assembly. Genuine parts are recommended for optimal performance.

Software-Related Solutions

MIUI, Xiaomi’s Android skin, occasionally introduces bugs affecting call screens. Try these fixes:

1. Update MIUI

Steps: Go to Settings > About Phone > System Update. Install pending patches to resolve known issues.

2. Clear Cache Partition

Steps: Reboot into Recovery Mode (Power + Volume Up) and select Wipe Cache Partition.

3. Disable Third-Party Call Apps

Issue: Apps like Truecaller or Google Dialer may conflict with MIUI.
Fix: Uninstall or disable them temporarily to test functionality.

4. Factory Reset (Last Resort)

Warning: Backup data first. Reset via Settings > Additional Settings > Backup & Reset.

User Testimonials and Real-World Fixes

Community-driven solutions often outperform official advice. Here’s what worked for others:

1. Adjust Display Timeout

Fix: Set screen timeout to 30 seconds to prevent accidental blackouts.

2. Use Safe Mode

Steps: Hold Power Off > Tap OK to boot into Safe Mode. If issues disappear, a third-party app is the culprit.

3. Replace the Proximity Sensor Flex Cable

Cost-Effective Solution: A $5 cable replacement resolved persistent black screens for many users.

Preventative Maintenance Tips

Prolong your Redmi 3S’s call screen health with these habits:

1. Avoid Extreme Temperatures

Heat and cold accelerate hardware degradation. Keep your device in moderate environments.

2. Use a Protective Case

A rugged case minimizes drop-related internal damage.

3. Regularly Update Apps

Outdated apps may introduce compatibility issues. Enable auto-updates in the Play Store.

Conclusion

Redmi 3S call screen issues stem from a mix of hardware wear and software bugs. By systematically troubleshooting components, updating MIUI, and leveraging community fixes, you can restore reliable functionality.
