Sony Xperia 5 Iii Custom Rom 〈Fresh〉

You likely flashed a ROM built from a source that didn't include Sony's AIDL fingerprint service. Try flashing a different vendor image or switch to crDroid (which has the best FP support).

A custom ROM is a modified version of the Android operating system that's designed to run on a specific device, in this case, the Sony Xperia 5 III. Unlike stock firmware, which is developed and maintained by the device manufacturer, custom ROMs are created by third-party developers and enthusiasts who aim to provide a unique set of features, performance enhancements, and customization options. sony xperia 5 iii custom rom
