How to encrypt your Android mobile and what do you get with it

25 mayo, 2021

Android security It is an issue that worries both Google, the owner of the operating system, and all its users, although each one for different reasons. The user wants to be sure that their data is safe, while those of Mountain View want the operating system to be secure so that companies can trust their services.

Our phones, as technology advances, are capable of storing more and more of our data, be it photos, videos, text files, information about our economy, and so on almost to infinity. That is why one of the features that Google introduced a few years ago is power encrypt our phone.

But what does that mean to encrypt?

With “encrypt” or encrypt your mobile we mean make the information on your device much less accessible usual. This is achieved by making sure that to get to certain information that you have stored you have to enter a password, so that if the phone falls into the wrong hands, you have some peace of mind that your data is not so exposed.

Once your mobile is encrypted, the music, videos, photos and application data will only be accessible if you enter the password or PIN code that you have configured before starting the process.

Eye, This does not mean that it is impossible for malicious people to access this data.It will simply be much more difficult, so much so that you can only get what you want if you know your password. Even if you manage to extract the data by passing it to the PC or in some other way you will be able to understand what you have, you will only be able to do so if you get the correct key.

What do I stick to if I decide to encrypt my phone?

Obviously, every process has a series of advantages and disadvantages that we must assess before carrying it out. Even something that gives us as much security as encrypting the phone has disadvantages, so we are going to list the best and worst of doing this.

The good thing about encrypting your phone

We have mentioned the main advantage of encrypting your mobile a little earlier, and it is that your personal data will be safe from almost any malicious attack. This means that, first of all, you can have the peace of mind that your data will only be seen by you and, furthermore, you will decide who will see it and who will not.

Even if your terminal is stolen, the criminal in question will not be able to access your personal data (photos, videos, bank accounts, etc.) if you don’t know the password for it. If you extract them, the only thing you will get is to see a lot of characters that you will not be able to understand.

The downside of encrypting your phone

As we said, even this has its disadvantages, but they may not be serious enough to put you back. The one that can affect you the most is that the performance of the smartphone is somewhat diminished, something that can be noticed especially in low-mid-range mobiles. In the current mid and high range this decrease in performance is probably not even noticeable.

The other problem, to call it that, is that on some smartphone models it is a process that cannot be easily undone, just doing a factory reset. Therefore, as soon as you encrypt your mobile, each time you turn on the screen you must enter the password to be able to use your phone and access the information it contains.

How to encrypt an Android mobile

Moving to the heart of the matter, we will now explain how can you encrypt your phone. In all versions of Android the process is very similar, the path in which this option is found may vary, but it will be very similar regardless of the brand of your mobile.

How to encrypt the mobile


First of all, we recommend that the phone be plugged into the power during the process, because it’s quite long. Second, you must have a PIN or password as a screen unlock method, facial recognition, pattern or swipe are not worth it.

Once you have configured a PIN or password, you just have to go to the Security section (the situation may vary depending on the Android version) in the settings of your smartphone and click on encrypt phone. After this you must confirm the PIN or password and wait for the process to finish, which it may take an hour approximately, and not interrupt it.

In case the phone has a microSD card, the data it contains will also be encrypted, so if you pass it to another terminal you will not be able to use them unless you first decrypt it (in case the phone allows it).

Encryption in Android Nougat

Android Nougat

In Android Nougat this encryption does not have to be for the entire phone, but you can run a small selection of applications as soon as you turn on the screen without having to enter the password. It can be useful if what you want is, for example, to make a call, but to access downloaded applications you will still need the password in question.

This is what is called file-level encryption, and its biggest advantage over the previous version is that in old phones that have updated to Nougat the process is faster because they do not have to decrypt a large amount of data at the same time.

As we have seen, encrypt the phone it is a fairly simple process, although quite long, which can last an hour in total, but offers you the peace of mind that your data is almost inaccessible. The biggest disadvantage is low-end devices, whose performance can be reduced. Are you one of those who encrypt your phone or do you prefer not to carry out the process?
