[MIUI Central] XDARoni:
While MIUI 12 brings many new features to explore, one of the most important updates comes in the form of the new camera app. The features available will be dependant on the Xiamoi phone that you have. So if you don't see a feature that we listed below, it might just be that your particular phone doesn't support that function. I am running MIUI 12 on my Xiaomi Mi 9T and I'll be going over everything new that you can expect to find in the MIUI 12 camera app.

App info:

App name: Camera

Version: 4.0

APK name: com.android.camera

What's new?

Customizable interface

The new customizable interface gives you more control over the layout of your camera app. When you open the app, you'll find quick shortcuts running along the bottom of your screen. These will give you instant access to things like video, portrait mode, pro mode etc. When you scroll all the way to the right, you'll find the more option. This will bring you to a list of all of the features in your camera app.

With the next MIUI 12 update, you'll find an edit button in the more section. When you select this option, you'll be able to drag features around and place your favorite ones on the app start screen. This makes it much easier to have quick access to the most used features on your camera. The feature I use the most on my Xiaomi 9T is the 48MP shot. Now I can go grab that feature and put it as the first option in my camera app. This makes it much faster to select that option quickly.

Pro Mode Settings

Pro mode is done in a very interesting way that makes things a little easier in MIUI 12. On most phones, you'll find the full list of pro features right on the bottom of the viewfinder. In MIUI 12, only the essential and most commonly used settings will be shown on the bottom. Additional settings are in a menu in the top right. Once this menu is expanded, you'll have access to the full array of settings on one screen.

This new layout is very effective at making pro mode simpler to use. Previously, it could be difficult to navigate pro mode with so many different settings in one spot. I've found myself using pro mode much more often than I normally would, thanks to the new layout.

Magic Clone

Of course, there are some really fun new features as well. Magic clone is a very nifty mode that lets you clone yourself in a photo. This option can be found in the more section of the camera app. In this mode, you can duplicate yourself in a photo or video. This trick is actually pretty effective at what it does. While I doubt I'll ever actually find myself using this for anything, it's kind of fun to mess around with for a while.

Subtitles

A feature that I was not expecting to find, is the fantastic new subtitle system. While filming a video, you'll be able to put subtitles on that video in real-time. Your camera app will be able to transcribe your speech and create a complete subtitle track. This makes it very easy to quickly make a video that can be viewed with no volume. There are many times where a friend sends me a video, and my environment might be too noisy for me to hear it properly. This solves that issue in a very effective way.

It also comes into play for social media sites like Facebook, which automatically start playing a video with no audio. Now your video can start playing with subtitles, and the viewer doesn't need to turn on the sound if they're in a public spot. If you've ever spent time adding subtitles to a video, you know how much of a time-consuming process this can be. It's great to see this simple solution that can save so much time.

I would like to show you this feature in action, but it doesn't seem to be available on my Mi 9T yet. I will update this thread if I ever get that feature. If anyone else has this feature working, please leave a comment with some screenshots.

Shoot in Fullscreen Mode

Your new camera app will have a new update called fullscreen mode. This mode lets you extend your preview display to the corners of your screen. Normally, your preview window will be a smaller screen in the middle of your phone, leaving room for your controls and settings at the top and bottom. Now you can extend this window to the entire display of your phone. Settings will overlay the preview window and still function as normal.

This is a good way of enlarging your preview and making things a little easier to see.
