Scores

Durability

When considering the long-term usability of these devices, their release timeline and software support are key factors. Both the Galaxy S21 5G and S21+ 5G were launched in January 2021. Samsung initially committed to providing four generations of Android OS upgrades and five years of security patches for the S21 series. However, as of February 2026, both models have reached the end of their official software update support, meaning they will no longer receive new Android versions or security updates.

  • Software Longevity: Both devices have concluded their official software support as of February 2026, having received approximately five years of updates since their release.
  • Physical Durability: Both models feature an IP68 rating for dust and water resistance, allowing submersion in up to 1.5 meters of water for 30 minutes. Their displays are protected by Corning Gorilla Glass Victus, offering enhanced scratch and drop resistance.
  • Expected Practical Lifespan: While software updates have ceased, the devices remain functional. Users should consider that continued use without security updates may pose increasing risks over time.
