We all cannot afford expensive mobile phones like Huawei Honor, Samsung Galaxy or Sony Experia. Those of us who do not have the budget to buy these highly sought after phones compromise with some features and have to stay content with lower end mobile phones. There are two main problems with such low end mobile phones – the manufacturer almost never updates the Android OS to latest version (so if you bought an Android KitKat phone, then it will never get updated to a newer Android version like Lollipop or Marshmallow) and the hardware of the low end mobile phones gets worn out easily.
Take my Android KitKat mobile for example – its volume up hard button does not work and the power button has to be pressed a little harder to make it work. These buttons are of cheap quality and they wear out easily after being pressed only a few hundred times. An easy way to prolong the life of these hard buttons (basically the power button, volume up button and the volume down buttons) is by avoiding their use on a regular basis. The free app (or rather a widget) called ZERO Lock Screen can help you do exactly that.
This app really does nothing but locks the screen of your device – just as you would do by short-pressing the power button. This app has no options at all and there is no user interface to be seen. But you can drag the icon of this app on the home-screen of your Android device and touch it whenever you want to lock the screen. This way you are avoiding having to use the power button of your phone and thereby extending its life by roughly a factor of two.
The ZERO Lock Screen app does not automatically prolong the life of the power button in Android devices, unless you get in the habit of using it every time you need to lock the device.
