We would like to apologize for any inconvenience. I don't have a Samsung A5 here with me, however, I was able to test your form with an Android phone that has Version 6.0 (Marshmallow) and the calculation seems to be working as expected.

Please allow me to create a screenshot and I'll get back to you as soon as possible.
