Electronic devices, like everything that treads this planet, become “old”. This is not only and exclusively that they remain more or less obsolete (certain devices can work just as well with the years that have), but rather that they end up contracting some “pains”: the keyboards have keys that do not work, screens some pixel dead and the mobile phones can show gaps in part of their entry physical. Suppose that this latter case should happen to you, and that the power button on the screen (and the phone in the last instance) it stops working. Does that mean that it can’t be unlock never your terminal? Or a lot less. You may also be interested in unlock the mobile in a more simple and intuitive. Let me show you how unlock your Android device without the power button.

Native methods

Before whizzing off to recommend applications, it is always good to explore what options we give our phone to achieve the objectives that we have raised. Let’s see what we have at our disposal for this particular case.

Through the biometric sensors

In a terminal that has a few years the power button is almost a heritage vestigial. When you can unlock your phone with a fingerprint (or, directly, with your face), or you need to turn on the screen, or a third-party application. Obviously, to be able to use them it is imperative that your phone has them. If it is relatively recent (about five years) and possibly include these functions.

When you do the first setup of your phone, the system asks if you want to set up a fingerprint, as a minimum. If in your time you didn’t and now you’re considering seriously to do so, go to the path Settings > Security and location (the path may vary depending on the manufacturer and your ROM). Beam scroll down and you’ll find the configuration of both things:

Tap Fingerprint and then in Add thumbprint:

Then you’ll have to press against the icon of the fingerprint and lift several times the finger of your choice, until it is perfectly configured.

With this it would be enough to unlock the phone with your fingerprint, but additionally you can set up the face unlock. Again Settings > Security and location and tap Face unlock. You will receive a small warning before you can configure it, indicating that it is more secure to use the fingerprint, a PIN or an unlock pattern, but if you click on Following you can move on to the next phase:

Then you will come to the screen to set up the face unlock. It is as easy as placing your face in the middle of the frame that appears in the camera, and it will be ready:

With these two methods biometric no longer dependerás of the physical button anymore.

With the gesture control on your Android

This method is not as general as the previous two, because not all Android phones will have gesture necessary for our purposes. However, it is worth to check. The gestures that we are interested in are the following:

  • Double tap to turn on.
  • Double tap to block.
  • Lift to check the phone.

Some manufacturers have incorporated the three, others some and others none. All the information about the gestures that your phone brings configured by default is in the paragraph Settings > System > Gestures.

Through third-party applications

If for whatever these native methods are short, you can always resort to the outsourcing to achieve the same thing. We explore below what options you bring to us independent developers to unlock our terminals.

Gravity Screen handles take away off having to turn on or turn off the screen of your phone. Not only does that the power button is completely obsolete, but that does not require any interaction on your part.

And how is this possible? Very simple: through the data provided by the motion sensors of your Android, you can unlock your phone as soon as you take it, as keep it in your pocket, as you leave it on the table. Depending on the action you take, the application turns on or turns off the screen for you.

Start working with her is nothing difficult. In the first place, download and install it. This will be the first thing you see when you open it:

Don’t draw a lot of attention, it is a summary of what the application does. The following is important:

If you have security measures biometric or Google Smart Lock is configured (or the two things at the same time) it is important to say, because, otherwise, Gravity Screen could turn off and lock your terminal when not to. Once past these obstacles, you will arrive here:

Setting Gravity ScreenSetting Gravity Screen

This is the configuration screen Gravity Screen. Here you’ll be able to spin fine with the settings if you so desire, though the ones that come enabled by default are more than enough. One that I recommend you activate is the power to turn off the screen in any direction (very useful if carrying in the pocket) and the protection of accidental power on, but as I said the default settings are sufficient if you don’t want to disrupt your life.

WaveUp, add a gesture to your terminal

Do you remember when above we speak of the gestures to turn the screen of your phone, and that some were not included in all devices? Well, this app adds a gesture to the list of those that come included by default with your Android.

We refer to WaveUp, an application that turn on or off the display of your terminal when you pass the hand over the screen. To do this takes advantage of the sensor that the phone has on the top of the screen, right next to the speaker.

This app it is also very easy to set up. Download it, install it and open it. This will be the first thing you see:

Activation of WaveUpActivation of WaveUp

The first will be to activate it, with the control that you have highlighted. Once you have done this, the app you will be asked a series of permissions with the aim of knowing if you have that turned off when you call by phone, and nothing more. The application itself warns you:

Notice of request for permissions WaveUpNotice of request for permissions WaveUp

Tap Ask and move to the next phase, in which you will have to ensure the permissions:

Granting permissions to WaveUpGranting permissions to WaveUp

This is done, we find the configuration menu WaveUp:

Main menu WaveUpMain menu WaveUp

By default it comes with a few basic options are turned on, but, if you want to lock the phone without even touching the power button, then you will have to activate the option Lock the screen. In the first place, you will be asked to give access to the accessibility options:

Grant it the permissions you ask for. Now you’ll have access to more options that you can enable or disable:

Additional options of WaveUpAdditional options of WaveUp

For me one of the settings more interesting is Apps excluded. If you click on it will take you to your list of applications, with which you can create a “white list”. To include these apps in the white list, what you’ll do will be to avoid the lock gesture of WaveUp to work while you are running:

As you can see there was no difficulty, and it is one of the most useful applications to dispense with the power button.
