Answer 1

Unlock Android phone with broken power key

Your Android smartphone has a broken power key and you don't know how to unlock the screen? There are several applications that help us and stand as an alternative solution to the now broken power button.

It is important, in these cases, to avoid turning off the phone as some models have the ability to turn on only via the dedicated key.

Unlock the smartphone with the volume keys

One of the first alternatives we have is to use the volume keys as if they were power keys and therefore have the possibility to unlock our device using a physical key anyway.

There are two methods:

• Check your device settings and see if this option is present
• Use a free app

The application that I recommend is Volume Unlock, tested on various devices and on an old tablet where the power button no longer worked and has always been an excellent solution.

Application to unlock with volume keys - Download

Double tap on the display

The last option available is that of double tap on the display to unlock the device.

Some phone brands, such as Xiaomi, implement this feature by default and just activate it in the settings, so you can unlock and lock the device using the screen and avoiding the faulty power button.

If your device does not have this function then you can use a free app: Double Tap.

Hardware repair

Another possibility is to try to repair the power key, in some the key is only moved and just open the device and realign the plastic of the button with the key on the motherboard.

You can find videos on how to do this on YouTube by typing the name of your smartphone + repair power button or similar phrases (looking for it in English you will have a wider choice of videos to follow).

Answer 2

At the request of a visitor to the blog. I created this guide to show you how we can repair the button to turn off and turn a smartphone with Android. In this case we will see how to repair the button to turn off and turn on a htc mytouch 4g (T-mobile MyTouch).

Well when the button to turn off / turn does not work, obviously something has, in many cases what happens is that a particle of metal that makes the smart garment is dropped or damaged. Look at the particle of which I speak.

    Now look at the MyTouch 4G phone without this particle. In this we can see that only two metal parts shown in which the particle through His metal unites As we press the button to turn off.

The best way to repair this device would put a particle equal to function correctly But it is not easy to achieve this. I found an old phone because he had another wash it off. But if you do not have one old man eh solution I found is to hit a piece of foil of the same size as the original particle.

We can also do the following. Button you can turn off and paste this piece of foil with clear nail paints. Wherever we stick foil.

  Well folks this is all that is about as repairing the button and turn off. If you have a better solution please share it with us.

  Missing say that this guide can be applied to other phone that is having the same problem. Recall that something has to be a new phone because other oldies bring different button power cycling.
