Smartphones have become an inseparable part of our daily lives. This device likely carries records of our private conversations, photos, internet search history, and other personal stuff. Hence, increasing privacy and protecting your data are quintessential. Although it’s impossible to keep our privacy entirely secured on any smartphone, there are plenty of settings we can adjust to increase your security and privacy. Here’s a quick guide and tips on how to protect your privacy on Android smartphones.

Set a Strong Passcode

Phone Passcode

Passcodes provide the first line of protection against unauthorized access to your smartphone and personal information. This one’s a no-brainer. Passcodes can protect the highly personal data on your smartphone, including private messages, contact information, and even mobile banking data. Locking your smartphone also prevents random strangers from being able to get into it, and it keeps your data secured if ever your device is stolen or one of your friends borrows it.

Check App Permissions

You can allow some apps to access various smartphone features, such as your camera, location, storage, contacts, and more. An app will send a notification to ask for permission to use features on your phone, which you can Allow or Deny. Moreover, you can also change permissions for a single app or by permission type in your phone’s Settings.

Privacy Settings

To do this, go to Settings > Privacy > Permission Manager and read through each section to make sure no apps have access to services they don’t need.

Check out the list of permissions below and see what they do when turned on for an app.

Body sensors – Get sensor info about your vital signs.
Calendar – Use your default calendar.
Call logs – Access and change your call history.
Camera – Use your camera to take pictures or videos.
Contacts – Access your contacts list.
Location – Gets your device’s location.
Microphone – Record audio.
Nearby Bluetooth devices – Apps can discover and connect to nearby devices.
Phone – Make and manage phone calls.
Physical activity – Get info about your activity like walking, biking, step count, and more.
SMS – Access incoming and send outgoing text messages.
Storage – Get photos and other files on your phone.
Files and media – Use photos, media, and other files on your phone.

Keep Your Smartphone’s OS Updated

Software Update

It is also essential to keep your software up-to-date. If you don’t keep your phone updated, you are opening yourself up to vulnerabilities hackers can exploit to steal your data. According to the Federal Communications Commission, updating your phone’s operating system when notified to do so helps patch security gaps and improve your device’s overall performance.

On Android devices, you can update your software any time by going to Settings > About Phone > System Update. Remember that you shouldn’t miss the latest security updates!

Consider Using a Third-Party Messaging App

Messaging Privacy

Messaging apps are some of the most frequently used apps on our mobile phones, and this is where we mostly communicate with people and share information, even sensitive ones. That’s why security is very important when it comes to messaging. Instead of using the default messaging app on your smartphone, consider downloading a more secure option with self-deleting messages and other more vigorous privacy options like these chat apps.

Keep Your Sensitive Notifications Private

Notification

Other than locking your screen, make sure that you keep your sensitive notifications off your lock screen; they should not be publicly accessible. It is important to customize your phone notifications to hide private information. You have to consider private messages, company emails, or texts meant for your eyes only. Everyone has the right to digital privacy!

Browse in Private

Private Browser

If you don’t want Google Chrome to remember your activity, you can browse the web privately via Incognito mode. By browsing privately, Chrome won’t save your browsing history, cookies and site data, or information entered in forms. Otherwise, you may opt to use a browser other than Chrome like Firefox Focus which deletes your history after closing it.

Don’t Click Suspicious Links

Yes, you should be vigilant about everything you see and don’t just click any link you see or was sent to you. Randomly clicking links or going to unknown websites on your phone can put you at risk. Moreover, when you click on unverified links or download suspicious apps, you increase the risk of exposure to malware.

Phishing

Phishing is widespread, and it is usually used to hack into accounts and obtain sensitive information. According to Statista, phishing was the most commonly reported cybercrime in the U.S. in 2020, with 241,342 complaints. Your chances of being targeted by a phishing attempt are high, so you should be ready to respond if you accidentally tap a malicious link on your phone. But, remember, prevention is better than cure. So be mindful of suspicious links.

There you go! Make sure to maintain security by doing these things! Of course, completing all these is the ultimate goal, but every step you do adds to your online security and privacy.
