Sony’s flagship Xperia 1 VII smartphone is back on sale after a temporary halt in distribution initiated in July 2025. The initial pause stemmed from reported system issues and concerns regarding the device’s overall stability, following its launch aimed at competing with premium Android devices like the Samsung Galaxy S25 Ultra.

Root cause Identified: Humidity and Temperature Sensitivity

An internal investigation by Sony has pinpointed the source of the problems to defects developing on the Xperia 1 VII’s motherboard during the manufacturing process. Specifically, exposure to fluctuating humidity and temperature levels during production appears to have compromised the integrity of the boards.

Production Adjustments and Enhanced Quality Control

To prevent recurrence, Sony has implemented adjustments to its production procedures. These changes aim to mitigate the impact of environmental factors on the motherboard assembly.Furthermore, the company has instituted stricter quality control measures designed to identify and resolve potential issues before devices reach consumers, a direct response to the widespread motherboard failures.

Replacement Program Available

Customers currently experiencing issues with their Xperia 1 VII are encouraged to visit the official Sony website to determine their eligibility for a replacement unit. This program was initiated alongside the resumption of sales on August 25th, demonstrating Sony’s commitment to addressing the initial concerns and restoring consumer confidence.
