I tested Samsung's Auto Blocker and Google's Advanced Protection; you'll want both on

Two security features on Samsung Galaxy devices, Samsung's Auto Blocker and Google's Advanced Protection, were evaluated recently. Initially, it seemed redundant to have both, but upon enabling and exploring their options, it was found that they barely overlap, and using both offers better protection.

Auto Blocker is a Samsung security feature with a default standard level and a stricter maximum restriction level. The standard level prevents unauthorized app installations, blocks USB commands, hinders malware images in messaging apps, and stops software updates installed over USB. The maximum restriction level provides even tighter security. Auto Blocker is enabled by default unless turned off, with a toggle that automatically re-enables it after 30 minutes.

Advanced Protection, introduced with Android 16 for Samsung devices, is designed for high-risk users like public figures and those handling sensitive information. It consists of device protection and account protection. Unlike Auto Blocker, it is not enabled by default. To activate it, follow specific steps.

Both features block sideloading and 2G networks, but Advanced Protection goes further by blocking Chrome, Google Messages, Play Protect, and automatic restarts. Auto Blocker handles USB connections, dial codes, Message Guard, and Samsung-specific apps, while Advanced Protection manages Google apps and automatic restarts. Neither feature interferes with the other, but using both together leaves fewer gaps in protection.

While each feature doesn't cover everything independently, together they provide comprehensive protection. Auto Blocker safeguards the physical and Samsung-specific aspects of the phone, while Advanced Protection focuses on daily Google apps. For enhanced privacy on Samsung Galaxy devices, both features are recommended.
