Earlier, Sony launched the Xperia 1 VIII mobile phone in Hong Kong. It adopts a new appearance design that is different from previous generations. According to earlier Japanese media reports, it may be revealed that the mobile phone seems to have been replaced by a Taiwanese manufacturer.
According to earlier reports by Japanese media, they checked the FCC certification documents submitted by SONY for the Xperia 1 VIII and found that the address of the device testing company was changed from Shenzhen to Taoyuan City, Taiwan.

Although this change does not necessarily mean a change in the production location, considering that the Xperia 1 IV/V/VI were previously outsourced to American companies for testing when they were OEMed in Thailand, and the VII’s Chinese OEM was also switched to domestic testing, this time it brings relevant inferences.
Mobile Magazine’s short comment: The article also mentioned that there was a hardware defect in the Xperia 1 VII last year that led to a large-scale recall. Therefore, it is understandable that the new generation of the new machine chooses to change the OEM to ensure that the product quality is up to standard.
