Hi,
i recently had this issue on my android device ( Moto Z2 ):
04-23 10:49:32.513 19263 19289 I trace : Main.hx:37: time(NULL)=1556009372
04-23 10:49:32.513 19263 19289 I trace : Main.hx:38: Std.random(1000)=266
04-23 10:49:32.513 19263 19289 I trace : Main.hx:39: Math.random()=0.647641502087936
…
04-23 10:49:54.143 19367 19393 I trace : Main.hx:37: time(NULL)=1556009394
04-23 10:49:54.143 19367 19393 I trace : Main.hx:38: Std.random(1000)=266

This happend only in one of my apps, so i tested a bit and found that <architecture name="arm64" />
caused it. Without that line, it works fine. I hope this will help
