How To Make Your Cell Phone Safe

Protection against Hackers and Viruses

Smartphones today are small computers and thus susceptible to viruses and hacker attacks. But many users are not worried about it – with just a few measures, security can be increased.

Mobile phones are now more small computers than mini-phones. Nevertheless, most people – unlike their laptop or PC – do not worry about viruses on their smartphone. Users do not take security and privacy as seriously as they do with their personal computers. And smartphones are just as threatened!

In most cases, just a few measures are enough to protect the mobile phone from viruses and hackers. The notes are sorted by the difficulty of their implementation for the smartphone owner.

1. Activate the Screen Lock

The screen lock is especially important in case you lost your smartphone or it was stolen. This feature also helps to prevent anyone from gaining access to the data on your smartphone.

Set a PIN of at least 6 Characters

If possible, better use a six-character PIN instead of just four. A short PIN is far too easy to guess and easy to remember for a stranger watching the input. If your device does not have the functionality of a six-character PIN, then activate one of the other security measures presented below.

Biometric security

Many modern smartphones today have a fingerprint scanner, some even a retina scanner. Although the biometric sensor of the scanner can be tricked, this security measure is better than a PIN or password. It provides good security without unduly compromising usability.


Just like on a PC, a password is the hardest to work around and crack. A good password is a combination of uppercase and lowercase letters, numbers, and characters.

2. Install an Antivirus Program

You need an antivirus program for the minimum protection. These apps detect threats such as spyware, adware, ransomware, sometimes even certain types of phishing emails. There is absolutely no excuse not to install an antivirus product. Virtually all security manufacturers provide free versions of their programs (freemium or completely free). Just search for terms like “antivirus” or “security” in your app store and you’ll have many apps to choose from. Before installing an app, please take a look at the installation base and user comments. A good app must have at least 4 stars and a few million users.

PS: You will not find any antivirus for Apple iOS. However, there are dedicated security solutions for Apple, which include other features to increase your security.

3. Use Encryption

All modern smartphones come with the functionality to encrypt the internal memory of the device and the SD card. Encryption is needed to prevent anyone from reading your data in case your phone is stolen.

4. Don’t just install any App

There are millions of apps. Here are a few simple rules that will massively increase your security and protect your privacy:

Only install apps that many other users have installed before you and that have mostly positive reviews
Do not install apps from app stores that you do not know and trust. Never enable the installation of applications from the SD card or other app stores.

Be suspicious if an app calls for dubious permissions. Use common sense and stop the installation if you see that a game, for example, needs access to your photos, emails, or text messages.

5. Activate the Location Function of the Smartphone

This feature requires a network connection and allows you to transfer the location of the phone. Various apps make it possible to remotely take pictures with the front and / or rear camera when losing their smartphone, which are then sent to a cloud service. With these images, you can either identify the thief or find the place where you forgot your phone.

6. Activate functions such as remote “lock” and remote “delete”

The remote lock feature allows you to remotely lock your device. With the remote erase feature, you can remotely erase all your personal information from the device. So you can sleep at least quietly, if you lose your phone.

The device remains locked despite the complete data deletion. Note that these features are not available on every version of Android. Nevertheless, they are available in almost all security products for Android.

7. Activate the Automatic Backup

Mobile devices may be stolen or lost (and in that case you should use the “remote lock” and “remote delete” functions) or be damaged irreparably. In such cases, it is better to have all your data (settings, accounts, documents, pictures) stored in a safe place from which you can easily restore them at any time. Best of all, this feature comes completely free of charge from Google and is also integrated into almost every device.

8. Do not be easy prey for Internet Criminals

Never forget that your data is just as vulnerable on a mobile device as on a regular PC. Malvertising (malware through advertising) and phishing can still be a problem. Luckily, in almost all browsers, the pop-up windows are blocked by default and some have anti-phishing filters built in as well.
