Image becomes color to B & W

[VivekThummar52]

Hey there, I'm using this project for a long time almost 1 year and it works well but many times I have seen one issue, when I crop the image, sometimes it becomes black & white after crop, I don't know why this is happening but it's a little awkward situation because this problem not occurs in every device.

EDIT: DEVICE - VIVO Y21L VERSION - LOLLIPOP

I'm posting some sample images so that you can understand the case:

1. This one is before crop:

2. This one is after crop:

As you can see, before the crop original image was colored and after the crop, it becomes B & W. Please solve this issue ASAP, Thank you.
