I request Samsung to add a app lock feature to any apps, like in other OS. We know we have secure folder, but it makes a new space. So having a primary app lock is a must. To ensure privacy and security. The ui can be very easy, like the once in secure folder or in upi apps, where a small window pops up from bottom, with face/fingerprint/etc options. This is hands down the simplest and cleanest app lock ui there can be.
Please consider adding this feature in the earliest upcoming future updates.
