In stock Calculator app for NOTE4, when you type in 31.92×1.2÷1.92=, you got 31.2; while you type in 1.2×31.92÷1.92=, you got 19.95.

The two results should be same, but stock Calculator gives different results.

Confirmed affected NOTE4 models: N910U(up to XXU1ANL4), N9100, N9109W, N910C, N910F, N910P, N910T, N910W8.

Update 01/08/2015: Thanks to Patosbuddy, slink_59 and Redefined301, we now know that when your stock Calculator app showing a dot (.) as decimal mark, you are affected by this bug; when it showing a comma (,) instead, you are not affected. Whether it showing dot or comma depends on the display language of your NOTE4.
