I’m having problems with my zenfone 2 too. Did you built unreal from source? What platform are you targeting (ARM or X86)? Does it work in the android X86 emulator? If it is X86 platform my game and tests shows its not working, they even crash in the android x86 emulator. If its ARM my game crashes after i do some 5 to 6 load new level calls on the Zenfone 2 (libhoudini crashes - Libhoudini is the ARM emulator).
Can you post your tombstone file and the monitor log? The tombstone file is in the /data/tombstones folder (i had to root my zenfone 2 to access this folder).
Has anyone successfully build an apk that uses the android x86 ABI with Unreal 4.16?
