Hello, For Android / ARM, detection of CPU features is done by "detect_cpu_features()" in the file "pixman-arm.c". It relies on Android NDK functions and only checks for ANDROID_CPU_FAMILY_ARM. Whereas, it exists also ANDROID_CPU_FAMILY_ARM64 for ABI arm64-v8a ( https://developer.android.com/ndk/guides/cpu-features.html#functions ). Which means NEON implementation is not activated for this ABI.
Cheers, Sylvain
