Common Galaxy A21 issues we check at inspection

  • Screen damage (cracks, dead pixels, touch unresponsiveness). The PLS TFT display can be prone to cracks from drops, and touch input can become unreliable or cease to function in certain areas. Dead pixels are also a common complaint.
  • Battery health significantly degraded. As a 2020 device, the 4000mAh battery is likely to have lost a significant portion of its original capacity, leading to shorter battery life.
  • Charging port issues (loose connection, not charging). The USB-C charging port can become worn or damaged over time, leading to intermittent charging or complete failure to charge.
  • Software glitches or performance slowdowns. Older software versions or accumulated data can lead to lag, app crashes, or general unresponsiveness, especially on mid-range hardware.
  • Cosmetic wear (scratches, scuffs on plastic body). The plastic back and frame are susceptible to scratches and scuffs from everyday use.
  • Camera module issues (blurry photos, focus problems). The camera lens can get scratched, or the internal focusing mechanism may fail, resulting in blurry or unfocused images.
