On the other hand, unlocking opens up opportunities for deep customization, from redesigning the kernel to installing a full-featured Google Camera. However, remember: Redmi 8 Pro on the Snapdragon 655 processor has a unique feature – when unlocked, the encryption of data is reset, which leads to the loss of all files on the internal drive.
