Yesterday a # iPhone mask unlocking came # of topics on the hot search, mainly is Apple officially released iOS 15.4 official update, mask unlocking feature finally online, while adding new Emoji emoji, wallet widget, etc. Digital Gaijin is also recommended for iPhone 12, 13 users to update.

It should be noted that to turn on the mask unlock function, you only need to enter the system settings and select "Face ID and Password", turn on the "Wear mask to use face ID" switch, follow the prompts to enter the face ID, and then you can wear the mask to unlock the iPhone.

To know the current iOS version of each update will have some bug problems, this time there are a lot of trolling coming, many people are trolling the update of iOS 15.4 after the official version of the phone storage reduced a lot, some reduce about 1GB, some actually reduced about 10GB.

The most exaggerated is that some large-capacity at once reduced by about 20GB ~ In addition, the signal seems to be a little floating for a while 2.3 cells, a while full cell, the rest are good, the health is still 100 (before some official version of the upgrade after the crazy battery health degree).

We have been looking forward to the arrival of the official version from the beta version, after the update, wear a mask in the indoor unlock speed, but wear a mask in the sun unlock will be much slower, and even have to move the angle of the phone to unlock, in addition is the phone memory has become more used, I do not know why, but it is not so exaggerated, at least more occupied about 1GB of memory.
To sum up the real experience of some more authoritative digital bloggers, after updating iOS 15.4, the memory will be about 1.2GB less, the battery health will not change, in addition, the mask unlock and wear glasses unlock is still very silky smooth, but occasionally the user will be prompted to look down, etc. iPhone 12, 13 users rest assured that the update.

Finally, the editor suggests that the iPhone 12 or below is not recommended to upgrade, does not support mask unlock, the phone is hot, storage capacity plummeted, etc.. But to be honest, every version of the iPhone will have such and such problems, we rationalize, but for the mouthpiece unlock this point, iOS15.4 official version are worth upgrading.
