Smartphones have become an integral part of our lives. And for many of us, heavy use can result in a bit of wear and tear—especially on the moving parts (i.e. the buttons). In case of Android, almost all hardware button functions can be performed using on-screen controls or third party apps, but losing the power button can render your device practically useless.
Without a power button, you can’t turn the screen back on once it times out unless you restart the device, which isn’t practical, especially on devices without removable batteries. You can also connect the device to the charger or a USB data cable to wake it, but that severely limits your mobility. If you choose to disable the screen timeout feature, the battery will run out quicker than your wallet runs out of money. If you own the Sony Xperia T or TX, and find yourself with a malfunctioning power key, we’ve got something for you that should save the day.
XDA Forum Member recoba23 made a mod that allows you to wake the screen of your Sony Xperia T or TX using the volume keys. As you would expect, this mod requires you to have the screen on to be able to flash it, but you can do it via the USB method if your power button is already dead. It can also come handy if you simply prefer to use the volume keys to wake the screen.
