Can you send more information to our e-mail ProjectWorldOfSisters@gmail.com about your device type and system android version please? We know that some devices do not give the game 4Gb of ram it needs and for example give it 2Gb which is not in some android versions enough for unpacking textures for example. On most android devices game runs, still it is challenging to pack 60Gb of assets into 1Gb of .Apk And sadly some phones do not decompress textures as efficiently to let it run within limited ram of the phone. We would like to investigate deeper.
