    Yes, unlocking the bootloader on a Realme device typically voids the warranty — at least officially.

    📜 Realme's Policy (as of recent years):

    • Unlocking the bootloader is considered a modification of the software environment, which Realme states voids the warranty.
    • Even if you relock the bootloader later, signs of prior unlocking (like a modified bootloader status or tamper flags) might still be visible to service technicians.

    🇮🇳 In India (and some other regions):

    • Realme previously had a bootloader unlock tool (now discontinued for newer devices), and even then:
      • They clearly stated that unlocking would void the warranty.
      • You might still get service, but not for motherboard or software-related issues under warranty.
