If you are looking out there to wake up your phone without touching any buttons then you have come to the right place. You can do so by Double Tap To Wake, Camera Wave, Raise To Wake, and Voice Commands. While the names of these features may vary between implementations, the principle behind them remains consistent. Let us look at these features and see how they work.
Now before starting with them note that if you have a lock screen password or pattern lock, these features will wake the phone to the corresponding security login screen.
If not, you’ll be taken straight to the previous screen, which is either the app that you had opened before locking the device or the home screen itself.
How to Wake Up Android Phones Without Touching Any Buttons?
1. Double Tap Method
The double Tap method of waking phones is common in HTC Android phones and few others of such kind. Many Android phones call this feature knock-on or Motion launch system or ease of use. Whatever name you can call, this double tap feature allows you to wake up your phones through a simple double tap.
To achieve this task, the phone’s digitizer is constantly monitoring your input. When two taps occur in quick succession in roughly the same place on the screen, the system wakes up the device.
The main advantage of this feature compared to alternatives is the ease of use: double tapping the screen to wake the phone seems natural, especially if you’re a Windows user who is used to double clicking.
On most smartphones which support double-tap, you can also double tap the home screen to have the phone enter sleep mode. This means that you can both unlock and lock your phone using the system. Though only some smartphones can only be woken up using a double tap it is quite a convenient and intuitive method.
To avoid accidental triggering as it may happen when you keep your phones in the pocket or usually happens when the display touch sensitivity is too high, it is advised to have a lock screen password or pattern set up to give it a login system.
2. Raise To Wake Method
With stock Android Lollipop, Google introduced a new feature called Ambient Display. In principle, the gyroscope and accelerometer detect that you’ve picked up the phone and wake the phone up to reveal your notifications. Like in the new iOS 10, Apple has introduced a similar feature called Raise To Wake.
What is in a name as their implementation is fairly simple: you just need to raise your phone to have it wake up. This feature works fairly accurate, as there is little chance of accidental triggering because you rarely raise your phone without trying to activate it.
Also, this seems to be the best way of waking the phone up without touching any button, although the feature doesn’t work when the phone is lying on the table. Furthermore, Ambient Display can lower the standby battery life of Android phones by up to 20%, which is quite a lot.
3. Wave To Wake Method
Another method is Wave To Wake up without picking it up. In fact, with this method, you don’t even need to touch your smartphones. Instead, you only need to wave at the proximity sensor, which is usually located above the display near the front-facing camera.
There are times when your hands are too dirty to touch your phone but still need to wake up the device (to check the time, for instance), which is where this alternative wake-up feature proves its utility.
Samsung first introduced this feature on the Galaxy S5, but devices such as the Galaxy Note 4, the Galaxy S6 series, the Galaxy Note 5, and the Galaxy S7 series have received it as well in the meantime. Whether it’s called Air Wake Up or Gesture Wake, the feature had the same functionality on all of Samsung’s devices.
In more technical terms, the software is constantly monitoring data coming from the proximity sensor and will wake up the phone when it detects that your hand is close to the screen. Also, the best of these systems also pull data from the gyroscope, meaning that they won’t activate the device if it’s not sitting it isn’t laying on a flat surface.
4. OK Google or Voice Command Method
With the Google Assistant in Android Google Pixel or voice commands in Windows, devices can be woken up through voice. On most Android phones, you can invoke Google Now’s voice search from any screen following the corresponding setup procedure. On a limited number of devices, the OK Google command also works when the screen is off.
This feature was first introduced with the original Motorola Moto X but has since been made available to devices such as the Nexus 9, the Nexus 5, and the Samsung Galaxy Note 4. Unfortunately, no current-generation device supports voice activation when the screen is off.
The only disadvantage with the voice-enabled wake-up is battery loss. To be able to interpret your commands when the screen is off, the device needs to be constantly monitoring the input from its microphone. This requires much more resources compared to double taps and camera waves.
You can now choose any of the above methods or try all and see which becomes your favourite to wake up your phone without even touching any physical button.
