An SMS OTP protection feature delays SMS retriever hash delivery for most apps, preventing hijacking attempts. Users now have the option to customize the shape of their app icons. Improved garbage collection in the ART engine should result in better performance and battery life. Health Connect gains native step tracking using device sensors, simplifying step tracking code.
