Samsung has introduced a new security feature called ‘Auto Blocker’ as part of its One UI 6 update for Galaxy devices. Auto Blocker is an opt-in feature designed to prevent the side-loading of potentially risky apps (APKs) downloaded from sources outside the Galaxy Store and Google Play. This move aims to protect users from social engineering attacks that might lead to malware or spyware infections. Importantly, Auto Blocker is not enabled by default, allowing users to maintain flexibility for installing APKs from unofficial sources.
Another significant aspect of Auto Blocker is its ability to conduct app security checks, powered by McAfee, to identify potential malware. However, it’s worth noting that this feature is not currently available on U.S. carrier models. Additionally, Auto Blocker adds a layer of security by blocking unauthorized commands and software installations via the USB port, ensuring the safety of users while charging their devices at public stations.
As part of the One UI 6 update, Samsung has also improved its Message Guard feature, expanding support to popular third-party messaging apps, including Messenger, Telegram, KakaoTalk, and WhatsApp. Initially focused on protecting against zero-click attacks in Google and Samsung messaging apps, it now provides enhanced protection in a broader messaging app ecosystem.
Auto Blocker and the updated Message Guard are accessible on Samsung Galaxy devices running the latest One UI 6 version. While the Galaxy S23 series has already received the update, many other eligible devices are expected to follow, strengthening security for a wide range of Samsung users.
While these built-in security features provide valuable protection, users seeking robust security should also consider using a third-party mobile security solution from a reputable vendor to complement their device’s defenses effectively.
