PROTECTING PRIVACY
Android M will be compatible with fingerprint scanners so device users can verify their identities by pressing a button instead of entering a passcode. Apple's iPhones began using a fingerprint reader in 2013.
Besides supporting fingerprint scanners, Android M will make it easier to users to prevent mobile applications from grabbing their personal information. Permission will only need to be granted to each app if the access is needed for a specific action. That means Android users won't be asked to share information about their contact lists, photo rolls or locations until an app won't work without it.
