Xiaomi Redmi 9AT/9i MIUI 12 Android 10 Features

There are plenty of features added in the Android 10 based MIUI 12 version compared with the MIUI 11 version. Here I mentioned some important features. MIUI 12 comes with both exclusive Xiaomi and Android 10 general features.

MIUI 12 Features

Here I will mention only features that are not available in other mobile manufacturers’ Android 10 versions, exclusive to Xiaomi mobiles.

Improved Privacy features

From Android 10, every mobile manufacturer takes privacy as a serious concern. But MIUI 12 is more accessible, and you have complete control over system apps. Xiaomi also has security features.

Mi Share

It is an Airdrop alternative from Xiaomi. You can send the files to Xiaomi, Oppo, Vico, and Realme phones. The list will increase to other manufacturers in the future.

File Manager Memories

File Manager can now show Memories like Google Photos. Based on your Photos and video date, It can produce random reminder-based videos or slideshows.

Ambient Display Customization

The ambient display views necessary notifications and time while saving battery power. Because of this, most of the mobiles stick with minimal setup. While preserving the power in MIUI, you can customize the display.

File Manager Improvement

With the new File manager, you don’t need third-party apps to open the document files. It can spread most PDF, Word, and other document types without additional apps.

Tasks Tab in Notes

Now you can add tasks in your Notes app. You can use Notes for simple reminders and shopping lists. We can use functions before travel preparations; they may not have features like Google Keep and Tasks. But We can use native apps for minimal tasks.

Disable All Sensors

Putting your mobile into Flight mode will disable the Network antenna and other sensors. But It will not disable all sensors. In rare situations, you may need to disable all your mobile Sensors. Using this new MIUI feature, you can do the process. Even if it may not help most users, the part is there.

Live Caption

You know this already; if you turn on Subtitles on Youtube, It will auto-generate the captions. It Doesn’t require Wi-Fi/ Data. We can work on the Same functionality all over your device videos. This feature is not yet available. But, It will be rolling out soon.

The language limit depends on Google Data.

Smart Reply

It is already available in the Pie version. But it is limited. Now you can explore more actions when you get the messages. You can Open Links, Open Apps based on the Messages.

Sound Amplifier

You can do many things like Reduce noise, Enhance the Tune like that. We always do this using Third-party apps. Now we can adjust the Volume and Tune, Equalize using the in-built feature.

Enhanced Gesture Navigation

The True Gesture Navigation has finally arrived. It may not be best compared with OnePlus devices, But It is way better than the Pie 9.0 version. If you swipe From Left to Right, It goes forward. Right to Left goes Backward. Home button work as usual. You can access recently used apps By Swiping Quarter Screen to the Top. Simple Navigation to avoid confusion.

Dark Mode

It is not like Night Mode. It didn’t add a filter on display. If you have OLED Display, It will surely save your battery power from 5-30% based on your usage.

Privacy

Google always added enhanced Privacy features in every Android version. In the 10th version, You can handle your privacy a lot better. It will always tell you when your installed apps access your location in the background to manage whether you need that permission on Always or During the app usage.

Direct System Updates

Unlike regular OTA updates from your Manufacturers, the frequent patch updates will be handled by Google After you update to the Android 10 version. The update will utilize the Google Play App. If you have Custom Skin OS from your Manufacturer, Google will not change the UI. They will handle only Patch updates. The direct Security patch update is one of the most critical steps taken from their side. It will help all the users who are tired of their manufacturer’s Late updates.

Focus Mode

It can be an additional function of Digital well-being. Now you can Pause some apps to avoid the Notifications For a short time or a Long time. Some mobiles are made based on this scenario. To avoid distractions and get focused on what you are doing. Think you are Studying, and a Single Whatsapp message can redirect you. With the help of this feature, you can use only Study apps during your Study time.

Family Link

It is like Parental Control. You can control the App Timings within your Added Google Accounts.

Other improvements and changes

HEIF Image, Monochrome Camera Support.

New Set of Emoji.

Enhanced Adaptive Battery Improvements compared with the Pie version.

Contaminant Detection- Your mobile will alert you if any moistures are in your USB Ports.

Attentive Display- If you look at your mobile, It will always wake.

You can use three-finger gestures to take a screenshot.

Final Words

If you are in Stock firmware, Use the Internal memory or Stock recovery-based method. It is comfortable and safe; You can update it like a Regular OTA Update. But if you were already using Rooted devices, You can try TWRP based method. Don’t download any third-party apps; sometimes, it may trigger the updates process. There are a lot of new Gestures available in this update; try them also. In my opinion, When you hate MIUI, You can try to root your Xiaomi Redmi 9AT/9i and install custom ROMs. They are better compared with some other Custom Skin OS. But the new MIUI is better. So try to use this OS instead of a Custom OS. But the decision is your choice…:)
