As a result, you might have concerns that your private information and data could be lost or compromised. When connecting to another device, you might also worry about who can see that data, and how to keep it secure.

At Samsung, we’ve thought of all this and made it is our mission to provide you with a secure way to share.

Private Sharing with Quick Share

Ever been in a situation like this? You want to share pictures of your newborn baby, or a video from your recent holiday, but don’t want to risk them somehow ending up online or visible to anyone other than those you intended.

Samsung Galaxy has a built-in solution to this problem: Quick Share’s Private Sharing¹, a privacy-preserving file-sharing function that lets you share your data with peace of mind.

With Private Sharing, you and you alone own the data. You can ensure that only the designated recipients can open the files you send – no one else. You can also set permissions and expiration dates for the data, so it’s only viewable for a limited amount of time. Further, you can give read-only access without the ability to re-share; revoke the data access whenever you like; restrict screenshotting, and see when the recipient received and opened the file.

Private Sharing makes it safe and easy to share your content, and you can share up to 20 files at once with a total size of under 200MB². And of course, all your files are encrypted when shared, courtesy of blockchain-based encryption technology.

To use Private Sharing, select the file you want to send and tap the Share icon. Tap Quick Share, followed by the three dots for more options in the top right corner. Then select Turn on Private Sharing. Once the message has been sent, you can check what you’ve sent and change the expiration date or revoke sharing permissions.

With Quick Share’s Private Sharing, you’re in control of your data and whom you choose to share it with, and you’ll be kept up to date every step of the way.

Enhanced Data Protection with End-to-End Encryption

Galaxy’s Enhanced Data Protection secures your data in the Samsung Cloud.

Enhanced Data Protection is a function applied from One UI 6.1 and tablets after Tab S9 including Tab S8 with Android 14 OS update. Enhanced Data Protection offers additional protection for Galaxy devices when you sync or back up your data with the Samsung Cloud³. This feature mitigates data loss via end-to-end encryption, which means data can only be encrypted or decrypted on your device and cannot be seen by anyone but you. In other words, you can connect to other devices while staying secure, and your data will be kept safe even if a server is compromised or account details are stolen.

When you activate Enhanced Data Protection, you’ll be prompted to write down a recovery code to help prevent the loss of your data in the event you lose your device.

To use Enhanced Data Protection, open the Samsung Cloud app, tap the three dots for more options, choose Settings, and then Enhanced Data Protection. From here, you can choose to encrypt backup or synced data. Alternatively, you can open your device Settings and go to Security and Privacy to find this feature.

End-to-end encrypted data is only accessible on devices using the Enhanced Data Protection feature, and cannot be accessed by anyone else, including Samsung.

We know that our users want to be able to enjoy their lives safely with the knowledge that their devices and data are protected. Galaxy enables you to do just that – so you can safely go out there knowing we have your back.

Our powerful Galaxy security solutions provide multiple ways to protect you from cybersecurity threats by securing your device and helping control your privacy. Auto Blocker and Message Guard are two of these safeguards.

Auto Blocker

Auto Blocker is all about choice — providing an opt-in package of additional security measures, so that you are completely in control to choose whether you want to explore the customizations enabled by Galaxy’s ecosystem. Auto Blocker will protect your Galaxy device and personal data in various ways by checking for malware and other cybersecurity threats and blocking malicious activity.

One example of Auto Blocker in action is the prevention of downloading apps from unverified sources.

Auto Blocker can also stop harmful commands from entering your physical USB port — which could come in handy when charging your phone through an outlet at a public space like an airport.

Turning on Auto Blocker is a quick and simple process that takes less than a minute. Open Settings, go to Security and Privacy, then tap Auto Blocker and select On.

Message Guard

One threat that is becoming increasingly common is the zero-click attack, which exploits vulnerabilities in your device software. This can take place any time an image file is received and does not require any action on the recipient’s part.

Samsung’s Message Guard acts to neutralize such threats by trapping the file in an isolated space on your device. While this file is put into quarantine, Samsung Message Guard checks it — processing it in a controlled environment to prevent infecting your device

Message Guard works with a range of popular messaging apps that you probably already use. You don’t need to worry about initiating the process either, once Message Guard is turned on, it runs silently and 24/7 in the background without needing to be activated in any way.

Although there is no doubt that cybersecurity threats will continue to evolve and become increasingly common, Samsung’s priority is to always keep with strong security. However, you choose to live your life, Galaxy is there —ensuring you stay in control.

Security Updates for Longer

While it’s important to have robust security features, it is also crucial to keep them up to date so you are protected against the latest threats. That’s why Samsung is providing up to seven years of security updates and seven years of operating system upgrades, starting with the Galaxy S24 series.¹  This is the longest period of software support currently available for mobile devices, allowing users to keep their phones safely and more reliably for longer.
