Sony Mobile claims Xperia Z5 family won't receive Meltdown and Spectre patches
Although many smartphone companies have already patched their flagships, Sony Mobile has a completely different approach (if any). In a reply to an Xperia Z5 Premium owner, a Sony Mobile rep said that the smartphone won't get a security update to patch Meltdown and Spectre exploits.
Since the Xperia Z5 Premium won't receive the security patch, it's likely that neither of the Xperia Z5 family smartphones will get it. It's unclear why the Japanese company has decided not to patch its handsets against these exploits, but since we're not here to judge, let's just say that it's a weird decision.
