Last month, Sony gave a summary for the cause of the issues that affected its Xperia 1 VII phones. To reiterate, the company blamed it on a faulty manufacturing process. More recently, the company shared a bit more details as to what went wrong. Then there’s the usual promise that this won’t happen again, but we’ll get to that in a bit.
According to a machine translation of the Japanese statement, the company says that the defect was caused by temperature and humidity fluctuations during the manufacturing process. This then caused issues to the circuit boards of the Sony Xperia 1 VII. In turn, this caused the affected devices to randomly power down or restart, or be unable to turn on.

For what it’s worth, Sony goes on to say that it has conducted a comprehensive inspection of the manufacturing process. In addition to fixing the issue, the company also vowed to strengthen its quality control for the production of future models.
The statement ended with saying that sales of the Sony Xperia 1 VII “will resume gradually from 27 August”. Which is interesting as the company started selling the phone in the local market on 25 August. Worth reminding that if you buy one before 5 October, you’ll also get the flagship WH-1000XM6 headphones forth RM2,099 for free.
