Is updating to iOS 15.4 worth it with its highly valuable upgrades?

For tech enthusiasts who love having the latest features, this update is a must-not-miss. Let's explore the new aspects of iOS 15.4 right away to answer the question of whether updating to iOS 15.4 is worth it or not.
1. New feature on iOS 15.4 - Unlocking Face ID while wearing a mask
Previously, one of the inconveniences of using Face ID facial recognition on iPhone devices was the inability to recognize when you're wearing a mask.
iOS 15.4 supports unlocking FaceID when users wear masks.Currently, wearing a mask when going out or even indoors is common, and having to pull down the mask every time you unlock your phone is inconvenient. Does this mean we have to resort back to traditional passwords?
Should you update to iOS 15.4 when this version allows unlocking with Face ID while wearing a mask.

When enabled, Face ID will recognize 'distinct facial features' around your eyes for authentication instead of identifying the full face.
With such an upgrade, you can easily unlock your iPhone in any situation without having to remove your mask. It's truly an extremely useful feature, isn't it? It secures your phone while also protecting your health.

2. iOS 15.4 adds many more emojis for you to express your emotions freely
Emojis are like GenZ's tool for expressing emotions, and the richer the emoji selection, the easier it is to express your feelings, isn't it?

3. What upgrades does iOS 15.4 have for the voice of virtual assistant Siri?
The iOS 15.4 update brings a new voice that can make interaction easier. According to Apple, the new voice does not clearly distinguish between male and female and has been recorded by a member of the LBGTQ+ community.

After the launch of iPhone 13 Pro models, users noticed that third-party apps didn't display all images at 120 Hz, which was quite annoying and diminished user visual experiences.
