The latest version of the iPhone system iOS 15.4 arrived as promised, just like the previous rumors, the biggest highlight is to support mask face unlocking, this system push contains
and above models. However, it is slightly embarrassing that because the Face ID of the iPhone 12 and above has twice as many dots in the formation as the old model, this mask face unlock function only supports iPhone 12 and above models.
iOS15.4 enable push support mask face unlock
The iOS15.4 update capacity is 1.21GB
In addition, iOS 15.4 version on the iPhone XS and later models, Siri supports providing time and date information when offline. I personally don't feel much about this feature.
In addition, this update also adds 123 new emojis (emojis) including pregnant men, melted faces, and trolls, is half of the 1.21GB update package occupied by memes? iOS for new model updates I think will become the norm, Apple also expects to promote users to buy new iPhones through iOS updates, which would have been understandable, but for most of the old model users do not have much use of the feeling of improvement, there is no incentive to upgrade.
