Why Microsoft has pre-loaded software?
Android 6.0 : Marshmallow
Android Marshmallow is a version of the Android mobile operating system. First unveiled in May 2015 at Google I/O under the codename “Android ‘M'”, it was officially released in October 2015.
Android Marshmallow introducing :
A new permissions architecture
A new power management system that reduces background activity when a device is not being physically handled,
Native support for fingerprint recognition
USB Type-C connectors: The ability to migrate data and applications to a microSD card and use it as primary storage
Doze: Doze is an intelligent battery management feature that recognizes when your device is not is use, like when it has been lying on a bedside table for a while, and enters hibernation.
App standby: App standby identifies apps that haven’t been used in a while and puts them into a deep sleep, which is basically the same thing as disabling them in the settings.
App permissions: The Android system now offers user-facing controls over some, but not all, app permissions. User will be asked to grant individual app permissions the first time an app attempts to access them.
Automatic app backup: Marshmallow can now automatically back up both your apps and data, so any apps restored from a backup will be the same as they were before – you’ll be signed in and right where you left off.
Network security reset: Network security reset is a nice little feature in the Backup and reset settings which allows you to quickly and easily remove all passwords, settings and connections associated with Bluetooth, cellular data and Wi-Fi.
Text selection: Instead of getting a temporary edit/share toolbar when highlighting text, in Marshmallow you’ll get a localized floating menu that offers three simple options: select all, copy or share.
Delete screenshots from notifications shade: previous versions of Android, when you took a screenshot the only option you had straight from the notifications preview was to share it. In Marshmallow, you can now delete it too.
Direct share: Direct Share is a new feature. It doesn’t work everywhere yet, but the idea is that when you hit the share picker, instead of just seeing a list of apps, you’ll see some contacts at the top as well. Theoretically you can instantly share the content with that person rather than head to an app in which you then need to choose a contact.
Chrome custom tabs: This is basically a Chrome-based in-app mini-browser that developers can use to display web page content within their app rather than having a user bounce from their app to a web app and possibly not make it back. Developers can color and brand the Chrome custom tab to look as much like part of their app as possible.
Marshmallow makes Android easier to use than ever before. At the same time, Android 6.0 adds a layer of advanced features for those that want to make use of them. There’s also a lot of tidying up and straightening out of Lollipop’s kinks.
Marshmallow makes more sense than Lollipop and improves on its predecessor in terms of performance, battery life and feature set. Marshmallow isn’t perfect, but its beauty is more than skin deep. There’s a lot beneath the surface for those that go looking.
