Although the Galaxy A21 was just recently unveiled by Samsung, information regarding the phone’s successor has started leaking already.

Now, a marketing video of the upcoming mid-range phone has been leaked.The video of the phone (SM-A217F) shows two features of the stock camera application: AR Doodle and Live Video. The AR Doodle mode allows users to record fun videos with virtual drawings and handwriting on faces or anywhere else. When the camera detects a face, doodles on the face will follow the face, while doodles in the space will stay fixed in the same place.The Live Video feature allows users to start live video streaming directly to Facebook, Instagram, and YouTube. Needless to say, the leaked video also confirms the final name of the phone, Galaxy A21s, something that was also revealed in the NBTC certification. The phone will be available in three colors: black, blue, red, and white.The Galaxy A21s is rumored to feature a 6.5-inch LCD screen with HD+ resolution, an octa-core Exynos 850 processor, 3GB RAM, 32GB/64GB storage, and a microSD card slot.
