How to Secure Android Phone from Hackers?

1: Use Phone Lock

The first and the most basic step towards securing your phone is setting the phone lock. It is the first thing that all users do when it comes to the security of their phones. So, if you have not done it yet, then do it right now.

Though it is the basic way of protecting your phone, mostly the phones without a lock are more likely to get harmed.

For instance, if your phone gets snatched that have sensitive information, such as your credit/debit card details, etc., and you have set the phone lock, then it will take time for the snatcher to unlock your phone, and meanwhile, you can take all the required actions to block your cards.

So, you see how having a phone lock can protect your Android phone. Now, coming to the types of phone lock, you have multiple options: setting, PIN, pattern, and password. So, choose any of the options to secure your Android phone.

2: Lock Apps & Media on Your Android Phone

You can also lock particular apps or media files to give an extra layer of protection. If you want to hide media files or apps from another person, use apps like App Lock/File Hide from the Play Store.

After locking your files using App Lock, you need to provide PIN Lock whenever trying to open the locked files or apps.

3: Download Apps from Legitimate Source

To protect your Android phone from hackers always downloads apps from a trusted source such as Google Play Store. Before installing any app, don’t forget to check its ratings and user reviews. Also, never overlook the Privacy Policy of the apps before downloading them.

4: Go Through App Permissions Before Downloading It

Another important step for securing your phone from hacking is reading the app permission. Before installing any app from the Google Play Store, you must ensure to read the privacy policy of that app and all other information related to the data the app will access on your phone.

For example, some camera app will ask for permission to access your current location that we know is not at all required. So, use the app that only accesses the required data.

5: How to Secure Android Phone with an Antivirus App?

Though Google Play Protect does a good job of protecting your phone from malicious apps, it is not enough when it comes to secure Android phones against viruses/malware.

There are so many other ways malware can infiltrate your device, hence you cannot only depend on Play Protect. In order to protect your Android phone from malware or any other online threat, you must have reliable and advanced antivirus software installed on the phone.

6: Avoid Using Unsecure Public WiFi

Everybody wants a free Wi-Fi network to access the internet. But remember that every Wi-Fi network or public wi-fi is not safe. There are hackers and cyber crooks who are always seeking the information transferred or shared between the Wi-fi networks.

If you are doing online transactions make sure your wi-fi network is protected. If you are using free or public wi-fi that is not protected then only use it for office use or entertainment, never browse personal or private data such as banking online, shopping online, etc.

How to Secure Android Phone from Theft or Loss?

1: Enable Find My Device Feature

No one can assure you that you will never lose your phone. There could be an instance where you may lose your phone, and in that case, Find My Device can help you to overcome the situation.

IMEI (International Mobile Station Equipment Identity) or MEID (Mobile Equipment Identifier) is one of the best ways to secure the Android phone from theft. All Android phones come with a serial number called IMEI or MEID.

These unique numbers are etched into the phone’s circuits, and unlike other stored information, it cannot alter on the phone. Your phone carrier already has the 15-digit IMEI number that can be used later to put your phone into the missing list of phones.

Even police departments ask for this number when you FIR for the stolen phone. You can find out the IMEI number on your phone box or in the phone’s Settings. Besides, you can also see it under the battery or get it by dialing *#06#.

3: Set a SIM card PIN

Another effective way to secure your Android phone from hackers is by entering the Pin for your SIM card. By doing this, you will have to enter a password every time the phone will restart or when you’ll buy a new SIM card.

As you aren’t going to do it often, entering the SIM card PIN will not be a hassle. It is absolutely worth adding a SIM card PIN to enhance the security of Android phones/tablets.

Wondering how will it secure your phone? Give it a thought what if you lost your SIM card and it went to the wrong hands. If the SIM card is not locked, the thief can easily make a call to find out the number.

And they can use your number on websites, and with the SMS from the bank, they can transfer money. So, you see how a simple step can protect an Android SIM card from such threats.

4: Enable On-Device Encryption to Theft-Proof Your Android Phone

On-device encryption is one of the default security features of Android that keeps the Android device secure from data breaches, leaks, and hacks. This feature uses encryption technology to encrypt the Android device and keep personal data, apps and accounts safe.

To let the encryption work on your device, you must set the phone lock with a PIN, pattern, or password. When the phone is locked, 256-bit AES standard encryption protects the data of the device.

If you are using Android 5 and above, then you can follow these steps to enable the On-Device Encryption:

  • Go to the Settings of your phone
  • Tap on the Security/Security & Location.

Go to Play Store Settings> General > Auto-update apps menu. Also, make sure to check that your OS is updated. To check the update of your Android OS go to Settings > About Phone > System updates.

3: Be Aware of Unknown Sources

Android anyway is a secure OS with advanced security features and it always blocks and notifies users when they try to download any software or files from an unknown source.

However, sometimes users totally ignore warnings of Android and download files from an unknown and untrusted source. But do you know that downloading software or any kind of file from unknown sources comes with its own repercussions?

Most of such files/software carry various types of viruses or malicious executable code. So, please avoid downloading anything from untrusted sources otherwise, you will end up with a virus-infected phone and as result, you will lose your access to data.

4: Don’t Share Your Location with Apps

There are so many apps that request you to share your current location with them. It is perfectly fine with some apps, such as food delivery apps, transport booking apps, navigation apps, etc. Even some apps can’t function at all unless you share the location data with them.

But is it worth sharing your location all apps? Absolutely no!! I mean what could be the purpose of a camera or normal gaming app asking for your location, it doesn’t make any sense. In fact, it is a matter of security concern.

That’s why always make sure your GPS is turned off and only enable it if is required. You can disable your location permission for a particular app on an Android phone by following these steps:

  • Open the Settings on your phone.
  • Go to the Apps.
  • Select the app for which you want to turn off the location permission.

That’s why we always suggest avoiding clicking on unknown links, ads and always have a good antivirus tool on your device.

2: Man-in-the-Middle (MITM) attacks

A MITM attack is a type of eavesdropping attack where attackers interfere in the data transfer or existing conversations. It can be found on the unsecured network.

Once you install the trojan on your device, it starts its unauthorized functions and harvesting your personal data from the phone to send or intercept text messages, connects your phone to a botnet, and many more risky things.

That’s the reason why you should never download any app from an unknown source because most of those apps contain different types of malware that can damage your phone.

4: Keylogger

Keyloggers are a type of spyware and monitoring software that records the keystrokes made by users. It is one of the oldest types of cyber threats. Keyloggers are insidious because without your knowledge they always keep their eyes on your every activity. 

They record all information you type into an app or a website and send these data to a third party. Keyloggers can steal all sensitive information you enter on the phone vis text messages, emails, financial information, browsed websites, login credentials, everything.

5: Mobile Spyware

Once the spyware enters your device it starts spying on your device. Hackers use spyware to spy on your phone remotely, monitoring & recording personal data & activities without your consent.

6: Mobile Adware

Adware is malicious advertisements that pop up on the screen. You must have seen ads showing while browsing websites or even using apps. Not all the ads are malicious but some of them contain viruses.

Once you click on those ads containing malvertising code, your device will get infected and adware enters into your device. That’s why you should never click on suspicious ads as the adware can steal your information and use it for unethical purposes.
