Overview

• Sony restarted Xperia 1 VII sales in Japan on August 27 as a gradual relaunch, following an earlier return to select European markets.
• The company says random reboots, shutdowns, and power-on failures stemmed from circuit-board defects caused by temperature and humidity conditions during manufacturing.
• Process changes now include tighter control of temperature and humidity in production and comprehensive inspections of related manufacturing steps.
• Sony has introduced a strengthened quality-control framework with a new management system to verify and evaluate manufacturing risks, already applied to replacement and current-sale units.
• Customers who bought the Xperia 1 VII before July 4 are eligible for a free replacement, and Sony has issued a public apology for the disruption and delays.
