Android is an open-source operating system that’s built on Linux. It was created by Google in 2008, and it’s the foundation for many other mobile operating systems, including Chrome OS and Amazon Fire OS. What makes Android unique is its ability to adapt over time through updates. These include both security patches and new features.

Material Design

Material Design is a design language that Google introduced in Android 5.0 Lollipop. It’s based on paper and ink, with bold colors, shadows, and animations that respond to the user’s touch. Material Design uses a set of principles for creating consistent experiences across platforms and devices. These principles include:

• Material surfaces – Surfaces are made of layers of paper or cardstock (or similar materials) stacked together with space between each layer; they have real-world physical properties like gravity and friction; they also react when touched by an object or person (like pushing through a stack of papers).
• Responsive interface – The interface adapts its layout to different screen sizes as needed so users can interact with it seamlessly regardless of what device they’re using or where they are within the app’s environment (such as zooming out when you need more room).

Doze Mode

Doze Mode is a new battery-saving feature in Android 6.0 Marshmallow. It’s similar to airplane mode, except that it doesn’t completely turn off your device–it just puts it into a deep sleep state where it can still receive notifications and calls, but all other activity is restricted until you wake it up.

Turning on Doze Mode will preserve more battery life when your phone or tablet isn’t being used much because its screen has been off for a while (more than 30 minutes). You can enable Doze by going into Settings -> Battery & power saving -> Battery optimization and tapping the slider next to “Don’t optimize.” This will prevent apps from running in the background while they’re not being used by you or anyone else who’s signed into your device with their Google account

Now on Tap

Now on Tap is a new feature in Marshmallow that allows you to use your device’s Google Now functionality from any screen or app. When you press and hold the Home button, Now on Tap will analyze what’s on your screen and provide information about it, as well as suggestions for related content. For example, if someone texts you asking “What time is your flight?”, pressing and holding down the Home button would pull up live flight times at airports near where they’re flying out of (if available).

If there are multiple options for what you want to do with Now on Tap–for example, if there are several restaurants nearby–you can also use voice search by saying “OK Google” before issuing commands such as “call” or “text.”

Settings Menu

The Settings menu has been cleaned up, and it’s much easier to find the settings you want. The options are now organized into categories, which makes it even easier to scan through the list of settings available. There’s also a search function present in case you can’t find what you’re looking for right away!

The new Settings menu has also added a way to access your apps and files directly from within this menu as well as improved organization and design throughout the entire system.

Data Usage

Data Usage is a new feature in Android 6.0 that allows you to view and limit your data usage on a per app basis. You can set limits for yourself, or have the OS warn you when you’re getting close to exceeding those limits.

If you find yourself running into overage charges each month, this may be a useful feature for keeping track of how much data each app uses so that it doesn’t go over your plan’s limit.

Battery Life

Both the Android 5.1 (Lollipop) and 6.0 (Marshmallow) have a battery life of around 24 hours, but there are some differences between them.

• Android 5.1 has Doze Mode which helps to save battery when your device is not in use by putting it into deep sleep mode when it’s not moving or being actively used for an extended period of time (like when you’re sleeping). This feature was included in Google’s latest update to Lollipop and helps make sure that your phone is still getting charged even though it may not be being used for long periods of time.
• On the other hand, Marshmallow has a Battery Saver Mode which automatically activates when your battery drops down to 20% so that you can continue using apps without having them close due to low power levels.

Security Updates

The latest versions of Android both come with monthly security updates. The difference is that Android 6.0 Marshmallow is the first version of Android to have them, while Android 5.1 Lollipop does not have monthly security updates but has some security updates.

As a result, if you’re looking for a device that will get you up-to-date with the latest in terms of security patches and fixes from Google, then you should consider picking up an Android 6 device instead of an Android 5 one (unless it’s something like the Nexus 5X or Nexus 6P).

The two versions of android are similar, but there are some changes.

Android 5.1 and Android 6.0 are similar, but there are some changes. Material design is the same in both versions of the operating system, but doze mode and now on tap are new features in Marshmallow. The settings menu has also been updated; it has a different layout from Lollipop’s version of this section of your phone.

The data usage section has been updated so that you can see which apps have used the most cellular data recently (or all time).

We hope that you found this article helpful. If you’re still trying to decide which version of Android is right for your device, we recommend downloading the latest update from Google and giving it a shot. Don’t forget that most new phones will come with Marshmallow pre-installed so if you want something new without having to wait too long then upgrading now may be your best option.
