On its Japanese support page, Sony has given detailed instructions for the update process for the affected models. If those steps don’t resolve the problem, Sony’s advice is to contact its customer service center. Interestingly, Sony’s advice suggests that the issues could be fixed with only a software update, but the company still says that it is currently investigating the cause of the problems. The announcement states that the company will provide more information once it is available, and recommends that people back up their data.I think Sony doesn’t really know what’s causing the Xperia 1 VII to experience these types of issues, and the software update is more of a precaution. The best option for the owners of the faulty units and Sony would be if everything could be solved with only an update. However, there’s also a chance that all this is caused by hardware problems, which could be the final nail in Sony’s coffin. The Xperia 1 VII is already more expensive and less compelling than virtually all its competitors, so a major hardware issue and sales suspension could prove critical for Sony’s mobile ambitions.
