ZTE Blade A31 Plus Disassembly Guide: Full Teardown Step by Step

This is a full disassembly (teardown) guide for the ZTE Blade A31 Plus, based on the teardown reference. Use it to open the phone for a screen, battery, charging port or mainboard repair — the ZTE Blade A31 Plus runs on the Unisoc SC9863A and secures its internals with 18 screws securing the back cover. Work slowly around the ribbon cables (FPCs) and the 3000 mAh battery.

Tools you need

  • Anti-static gloves and an anti-static wrist strap
  • Tweezers
  • A small Phillips screwdriver
  • A plastic housing opening tool and a thin plastic card
  • SIM/microSD card tray eject tool

💡 Opening the phone breaks the anti-dismantle tag and voids the warranty. Check the warranty and waterproof tags before a warranty repair.
