Foldable smartphones can experience unique issues due to their complex mechanical design. This troubleshooting guide covers common problems and solutions.

Display Crease Becoming More Visible

If the crease in your folding display becomes more noticeable over time, first clean the display thoroughly. Oils from your fingers can accumulate in the crease area, making it appear more prominent. If cleaning does not help, check for software updates that may include display calibration improvements.

A crease that suddenly becomes much more visible or develops a bump could indicate internal damage. If your device is under warranty, contact the manufacturer for inspection.

Hinge Making Noise

A clicking or grinding sound from the hinge is a concern. First, check if debris is caught in the hinge. Use compressed air or a soft brush to clean around the hinge mechanism. If the noise persists, it could indicate hinge wear or damage. Contact Samsung Care or your manufacturer’s support. Most foldable hinges are designed to last the device’s lifetime, but physical damage from drops requires repair.

Screen Not Opening Fully

If your foldable does not open to a completely flat 180-degree position, debris in the hinge is the most likely cause. Clean the hinge area thoroughly. If the problem persists, the hinge mechanism may have internal damage from a drop or impact. Avoid forcing the display open, as this can damage the flexible screen.

Touch Issues Along the Crease

If touch sensitivity is reduced along the crease area, clean the display. Oils or screen protector bubbles can interfere with touch. Check if the issue occurs only in specific apps (which may not support the crease area properly) or system-wide. If it is system-wide and cleaning does not help, a factory reset may resolve software-related touch calibration issues.

Cover Display Not Responding

If the cover screen becomes unresponsive, restart the phone first. Check for display protection mode that may have been triggered. If restarting does not work, boot into safe mode to check if a third-party app is causing the issue. If the problem persists, a hardware fault may require service.

Summary

Many foldable smartphone issues are related to debris, software glitches, or normal wear. Regular cleaning and software updates prevent most problems. For physical damage to the hinge or display, professional repair is typically required.
