Common Galaxy Z Flip 4 issues we check at inspection

  • Inner screen crease wear/damage. The crease on the foldable display can develop micro-cracks, delamination, or become more pronounced over time, affecting touch sensitivity or visibility.
  • Cover screen unresponsive or cracked. The smaller external display can suffer from impact damage (cracks) or touch input failures.
  • Hinge mechanism stiffness or failure. The folding mechanism can become stiff, noisy, or fail to hold position, especially after drops or prolonged use.
  • Battery health significantly degraded. The 3700mAh battery, after 2+ years of use, often shows significantly reduced capacity, leading to poor battery life.
  • Charging port issues (lint, damage). The USB-C port can accumulate lint or suffer damage, leading to slow charging or failure to charge.
  • Cosmetic wear on aluminum frame. The Armor Aluminum frame can show scuffs, scratches, and dings, especially around the edges and corners.
