Features of Android 9.0 Pie Operating System

There has been made a keen versatile makeover cum touch up over time in the Android Oreo to design and carve Android 9.0 Pie. With a number of significant new additions and developments, it has got a comparatively longer list of features. Some of which are highlighted below:

Flexibility in Brightness
You will be amazed to hear this, but this is true! Google is actually aiming at making smartphones smarter by making it learn from your habits and adapt according to your preferences.

So Android 9.0 now sports a new mechanism called ‘Adaptive Brightness’ that learns your preferred levels of brightness in different surroundings. By tracking user adjusted brightness, it will automatically set the screen brightness levels for you. Now don’t act like you weren’t impressed!

Slices is one of the best Android P features which comes in handy at several places. It lets you perform basic application activities outside the app. Let’s say you search for ‘Lyft’ in Google Search. An interactive Slice appears on screen that displays price and time for a trip to work so that you can quickly book a ride. In other words, Slices are fully functional User Interfaces that can be embedded externally in other applications to provide a variety of options to the user. Just like tons of other segments in Android, this feature also performs a deep analysis of your inputs and contexts to show you the best parts of the apps you use most of the time. Personally, i absolutely love this feature.
Improvement in Messaging Apps
Speaking of messaging apps, although today they are considered traditional and used much less as compared to earlier times, maybe for this one reason, Google has made a hell number of improvements to enhance the experience of texting. The images have been made viewable in the notification shade of all incoming texts. Apart from this it also has got another cool feature named Smart Reply through which you can reply quickly to messages through the notification shade and use suggested responses that are created by analysis of the incoming messages.
Default HTTP for Apps
The internet browsing works on two protocols: HTTP and HTTPS, with a major difference being the encryption feature of the latter. But not all apps use the secure protocol for communication which can expose you to potential dangers. Now all the apps built for Android P will communicate data via HTTPS by default. This will ensure the safety of your data while sending or receiving data from the app’s servers.
Art Improvements
Some Additional Changes in the OS will improve the Android Runtime (ART) resulting in a significant performance and efficiency boosts. This implies that apps can launch faster and consume less memory on your phone with Android Pie. Now is not that cool?
Notch Compatibility
Not everyone would prefer this, however, every smartphone manufacturer is following the trend of notch displays. And Google seemed a little unprepared since Android 8.0 had no support for a display cut-out. Henceforth, Android P features an edge-to-edge screen support with an option to “Stimulate a display with a cut-out.” The new feature will encompass different types of cut out modes like narrow, tall, and wide to suffice different notch dimensions. This option can be found after enabling the developer options. After doing so, follow Developer options > Drawing > Simulate a display with a cutout. Finally, choose the cutout size.
Gesture Navigation in Android Pie
Just as similar to iPhone X, Google has revamped the way you navigate the operating system by introducing Gesture Navigation in Android Pie. In place of three buttons set on the home screen, you get an option to use a new single home button that allows you to swipe up to view recent apps along with a UI that suggests apps you might use. It can surely send a chill down your spine. Sliding too far left and right across the device would showcase recent apps and letting you quickly switch between them.
Notify on Call Recording
Undoubtedly the Call recording feature is quite good, but what is better is its ability to notify all parties whenever a conversation is being recorded. As the call recording starts, the system will play a tone at an interval of fifteen seconds to alert the other person.
Zoom in Text
We can now get rid of the annoying mistakes of selecting incorrect text. Android P will now support Zoom lens feature. Basically what happens here is, when you long press a phrase, it will automatically magnify at the pointer. Not to mention, this will help you read small text and selecting words precisely. Maybe this is not sounding as much fascinating to you, but you have to trust me this feature is a boon especially for people who prefer reading books online.
Do Not Disturb Mode
For all our dear insomniacs and videophiles out there, Google has brought for you a gift you missed on Christmas otherwise. Wind Down is a feature that will allow you to turn on the night lights and Do Not Disturb mode as well at whatever time you want it. It not only silences the phone calls and notifications but also all the visual interruptions like notifications that frequently pop up on your screen.

Another gesture-based Android Pie feature called ‘Shush’ makes it easier to distance yourself away from calls and notifications by enabling Do Not Disturb mode.

Indoor navigation with Wi-Fi RTT
Android P now supports IEEE 802.11mc WiFi protocol which is also known as Wi-Fi Round-Trip-Time (RTT). It’s one of the best features that Android fans are waiting for. This new feature allows us to find our way across short distances within malls and large buildings i.e. indoor GPS style tracking by determining your location within a building and facilitating turn-by-turn directions to help you navigate indoors.
Vibration on pulling the notification drawer
A customizable feature- Vibration on pulling the notification drawer down. Hence allowing you to choose from options.
Revamped Settings App
The Revamped Settings App with options and features icons made more colorful than earlier.
Option to pair with up to 5 Bluetooth devices
Unlike Android 8.1 Oero, where you had the choice to simultaneously connect two devices via Bluetooth. In Android P, you can pair up to a maximum of five devices. It is crucial to note that this new feature is not for simultaneous playback, however, it works well with the new media panel. Which is another great feature?
157 New Emoji
Android Pie is now with 157 new emojis added and some revamped emoji designs. These emoji already existed in the Unicode Standard, but Google is now following its guidelines more closely. This also marks the removal of gender-neutral blobs. The new pack of interesting emojis includes a cold face, hot face, mango, and llama. A new line of redhead emoji is also added in Android P.
Pixel Launcher Dock
There is quite a transparent and corners with rounded shape of the Pixel Launcher Dock.
Picture in picture
Shortcut in the form of a gear button in PIP(Picture in picture) Mode screen that opens up the device Settings. This will help enable/disable the PIP effect on a particular App.
Clever Notification Panel
The notification channels on Android P have been redesigned and it now allows you to block the specific type of notifications from popping up on your phone.
Ambient Display
Battery percentage visible on the Lock screen- Ambient Display. A much-requested feature to show battery charge percentage on the Ambient Display has now been added to Android P.
App Actions
App Actions: To tell you in simple words, if you connect your headphones to your smartphone, App Actions will ask if you’d like to continue listening to your favorite playlist on Spotify, thus allowing you to skip several steps in the process. Such actions show up throughout the OS such as Smart Text Selection, the Play Store, Launcher, the Google Search app, and the Assistant. Hence anticipating your future action based on the current one.
Screenshot button
Screenshot button has been added. Press the power button and along with Power related options, it will show the screenshot feature. Another handy Android 9.0 feature is the addition of the screenshot button to the power menu. Thanks to this feature, you no longer have to struggle with the power + volume down buttons.
Multi-camera API
Multi-camera API to create a fused camera stream to automatically switch between two or more lenses. This allows for zoom, bokeh, etc features.
HDR VP9 video and HEIF image
HDR VP9 video and HEIF image compression support. The High-Efficiency Image File Format (HEIF) is a new image format developed by the MPEG group. Its advanced compression method retains higher image quality than JPEG images and creates smaller file size.
Enhanced Privacy Security
Along with the dates moving further and issues of privacy concerns like Facebook tracking your activities, it surely would be a great relief to know that Android has renovated its privacy factor in the latest version. Until now was a method that once you allow an app to access your camera and mic, it can use them whenever they want.

But Android 0.9 Pie will block apps running in the background from microphones and accessing the camera. If an app tries to use your camera without seeking your permission or without your consent, it will be shut down and receive system errors whereas apps that attempt to record audio will capture blank sound until you open the app. This indeed is something new and safer.

Android Pie also brings with it restricted access to call logs for better visibility and control to apps that need information like phone number identification and phone call record access. If an app needs call log access, it must explicitly request these permissions. Similar restrictions have been applied to phone numbers, WiFi location, connection information, etc. When we speak of further restrictions on the background apps, sensors like gyroscopes and accelerometers that use continuous reporting mode don’t receive events. Same applies to on-change and one-shot reporting sensors like step counter, proximity, and heart rate sensor, significant motion, etc.

Smart Replies
Smart replies in the message. It is the same as in Google assistant you get to select a few actions suggested by the Assistant
Neural Network
Now runs Neural Network API 1.1.
A Dark Theme
In the earlier times, Google automatically applied a dark or light theme based on the wallpaper’s color tone. But Android P features a notable option to manually change from different themes. Under the display advanced settings, you can select whichever theme you prefer. Again, the theme settings will only apply to the app drawer and the notification shade.
Doze Mode
Refinements have been made to Doze, App Standby, and Background Limits that aims to improve battery life. It learns to prioritize battery power by observing apps and services you use the most, thereby helping you get the most out of your battery, and make it last for a longer time. To further improve your battery saving experience, improvements have been made to battery saver feature. Now Android Pie doesn’t wait for an app to be idle and puts an app in standby mode more aggressively. Also, background apps don’t have network access and the limits are applied to all apps–it doesn’t matter if they target Android P or not.
Auto- Rotate Button
The addition of new contextually aware button makes auto-rotation a much lot easier and is one of the incredibly handy Android features I have seen. An auto-rotate button appears in the navigation bar when your phone is rotated to an orientation it’s not currently locked to.
Much improved Auto fill Framework with dataset filtering, input sanitization. Input sanitation helps in adding a credit/debit card number properly by adding space after four characters.
Password Managers
Auto fill also brings password managers to use the accessibility-based approach in apps that don’t have full Auto fill support.
Enabled Fingerprint Security
You will now have a more soothing and reliable experience with the Fingerprint security and it will now be more consistent
New Media Panel
Yup! You have read it right. At the end, we all have been heard of. There has been made a complete transformation in the entire media panel. The volume slider is now vertical and shifted to the right of the screen. And *drum rolls* the physical volume buttons will only change media volumes by default. The same media panel also features different volume options when connected to more than one device. This separates the phone volume from the volume of connected devices.
