In this day and age when our data is always under foreign threat whether it be malware or our phone getting into the hands of pickpockets. We tend to neglect simple practices that help us secure android phone.

Hence, It is essential to safeguard this single most important entity in our lives that not only carries our personal information such as social media credentials, contacts, banking data but also photos and videos of our moments with friends and family. The whole thing could become a painful experience if someone would sneak into our android phone just because we did not activate the most essential security features that came pre-installed in our phone.

Although, there are some customized security features that mobile phone makers introduce with the help of telecom operators but in this tutorial, we are going to explain the first security boundaries that we must play with and implement before thinking about extra measures for keeping the phone away from potential threats. We will try to list down all possible built in features that come with the gadget to show you the way to secure android phone.

We are taking into account 3 phones from different manufacturers including Oppo F5, Huawei Mate 10 Lite, Infinix Note 4 that have a common OS, Android Nougat, on them. Rest of the manufacturers integrate almost similar built-in security features to their respective phones.

For your data’s safety, it is advisable to go through the setting area and activate the security features whenever you buy the phone or if you are already using the one, make sure you checkout any unattended option to secure it.

1- Locking your phone, the first thing

This is the utmost important and the basic measure that most of the users still don’t adhere to. If you are starting the device first time, the system will ask you to activate the lock.

The simplest way to lock your phone is by setting up the standard modes, the pin codes, passwords, pattern or fingerprint scanners — though, the latter one is more popular today. But face recognition is also inspiring users and after having featured in flagship devices, it is finding its place in some middle order phones too, though, the accuracy to scan faces in this price category is not as strong as in top phones.

But, we still many people stick to the pattern lock. It is just a matter of personal preference whichever you choose. All of them will lead to a secure android phone.

Following images depict the steps to set up security features to secure android phone:

  • Open setting in your phone
  • Scroll to the security options
  • Tap security icon
  • Select the options for device security
  • Choose a suitable mode for your password

The above steps are almost similar in all three mentioned phones.

In different android phones, there are brand specific features. As you can see above Huawei Mate 10 Lite and Oppo F5 provide additional features such as facial unlock as opposed to Infinix note 4 which only provides fingerprint scanner and passcode options. In comparison, the other two provide extra security features.

However, while registering your thumb impression the end user is always required to create a pin code. It allows to access the phone if the fingerprint scanner or face recognition fails. It is advisable to either use Pin code or password as a means to secure android phone rather than only relying on facial locks and thumb impressions. The right form of combination would make it less likely to be hacked. Here are ways to make your passwords stronger and stay safe online.

2- Utilizing device encryption

What is device encryption by the way?

Prior to going through the steps concerning device encryption, it is important to know what exactly it is and how it could secure your android phone. The above picture we took from Chrispacia may help us understand that the plaintext we usually type on our screen is converted by the phone software into ciphertext, a random and meaningless text for the user and then decrypted again by the software when someone wants to access that data.

If you are WhatsApp user, you must have noticed the encryption message sometime on the screen which shows that your message are getting encrypted at the time of leaving your mobile phone. These big tech companies encrypt the user’s messages since they find it very important for the safety of data.

Device encryption converts the data stored on your phone in a state which can be read with authentic credentials. Hence every time you reboot your phone, there is a requirement to enter a password or a pin code to decrypt the data stored on your phone. Well, after encryption, you can call your gadget a secure android phone.

If the phone is lost then the only way to enter into your phone is through the encryption key.

Steps to keep in mind while enabling encryption

  • The phone should be either be plugged into a socket or it should be fully charged. If the battery is low there’s a possibility of data loss.
  • It is advised to backup data on your phone to any external memory storage or cloud service.
  • To initiate encryption one has to open settings
  • tap security
  • scroll down and find the encryption tab

11- Direct boot

According to the Android security centre, the direct boot would verify that the phones software has not tampered which is crucial for a secure android phone.
