Xiaomi Redmi 9C/NFC MIUI 12 Android 10 Features
There are plenty of features added in the Android 10 based MIUI 12 version, compare 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, and it is exclusive to Xiaomi mobiles.
Improved Privacy features
From Android 10, every mobile manufacturer takes privacy is a serious concern. Xiaomi also has security features. But in MIUI 12, It is more accessible, and you have full control over system apps.
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 videos date, It can produce random reminder based videos or slideshows.
Ambient Display Customization
Ambient display is to view 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 any third-party apps to open the document files. It can open most of the 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. Tasks can be used before travel preparations like that; they may not have features like Google Keep and Tasks. But Native apps can be used for minimal tasks.
Disable All Sensors
In rare situations, you may need to disable all your mobile Sensors. Putting your mobile into Flight mode will disable the Network antenna and other sensors. But It will not disable all sensors. Using this new MIUI feature, you can do the process. Even if it may not help most of the users, the part is there.
You know this already; if you turn on Subtitles on Youtube, It will auto-generate the captions. The Same functionality can be work on all over your device videos. It Doesn’t require Wi-Fi/ Data. This feature not yet available. But, It will be rolling out soon.
The language limit depends on Google Data.
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.
We always do this using Third-party apps. Now we can adjust the Volume and Tune, Equalize using the in-built feature. You can do a lot of things like Reduce noise, Enhance the Tune like that.
Enhanced Gesture Navigation
The True Gesture Navigation has finally arrived. It may not be best compare 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.
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.
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 updated 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.
It can be an additional function of Digital Wellbeing. 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.
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 compare with the Pie version.
- Contaminant Detection- If any moistures are in your USB Ports, your mobile will alert you.
- Attentive Display- If you are looking at your mobile, It will always awake.
- You can use three-finger gestures to take a screenshot.
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 9C/NFC and install custom ROMs. They are better to compare 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…:)
