The Long Goodbye: Installing a Custom ROM on the Sony Xperia 5 III
The Sony Xperia 5 III is a device that shouldn't work in the modern smartphone market. It is tall, narrow, and refuses to bend to the will of massive displays. It has a 3.5mm jack and a dedicated shutter button—artifacts of a bygone era. But for the enthusiast, it represents the pinnacle of compact engineering.
