Is there a way I can unlock an Android phone by using a fingerprint?

    The Motorola Atrix 4g has a true finger print reader built into the power button and it works great.
    the phone can be unlocked with a code or a swipe of your finger. Iphone was not first. I was hoping the Moto X would have it too, but sadly it does not.

      There may be a point of patents for this technology

      Thanks to respondents. There is conflicting point between respondents. May be a questions about patents!

    I'd like to note also that if you try any of the fake fingerprint scanner lock screen apps, there is a chance that it will lock you out of the phone until you figure out the trick and sweet spot for finger placement to "scan" your finger. Plus, most of these apps have adware and very questionable permission settings, making them unsafe to use. Best suggestion would be to use the pin code unlock option in the phone settings, and use something like Lookout Mobile Premium and enable the Lock Cam feature since it will take a photo of the person trying to unlock your phone after the third failed attempt. https://www.lookout.com/news-mobile-security/lookout-lock-cam-update

    I'm not aware of any phone out there having a touchscreen, button or camera capable to scan and distinct fingerprints. (The recently announced iPhone will be the first.)

    Basically all the Apps available on the market right now (including the ones listed above) are "fake", entertainment apps. They don't actually scan fingerprints but simply lock the screen and require some "trick" to bypass.

      Thanks. Appending a subquestion based on your reply for a cordial debate : Cordially asking you : But pl tell how is it proved that they "do not" use finger print technology. Is it hear-say or a proven evidence which you may weblink?

      I could ask you to search for the touch screens make and model and look it up but this information is mostly buried if available to the public at all. Nobody really cares about the details of the touch screen as long as it works, right?

      Most touch screens use capacitive technology which means it doesn't record an image of your finger put only detects distortion in the electrostatic field. Your body is a conductor and therefor whenever you touch it you introduce an distortion.
      Don't get me wrong, capacitive fingerprinting is technically possible but it is a work in progress.

      Or, why does Apple implement the fingerprint into the new iPhone 5S home button (which usually brakes before the rest of the mobile) instead of using the screen? Simply because a screen that size capable to produce the resolution to scan a fingerprint costs a little fortune.

      Also imagine the legal issue if smartphones were found out to be able to collect biometric data? In most parts of the earth you actually need legal approval or the persons approval to gather their biometrics. That would be a lost law suit – unless it was stated somewhere in a legal document shipping with the device which someone would have surely made public by now.

      Thanks. I understand your details about original fingerprint feature.

      You realise these are fakes right? A SCREEN cannot scan a fingerprint!
