Who uses on the new Samsung Galaxy S7 the preinstalled calculator might have problems with the calculation in percent. In the calculator version which was installed on smartphones like the S4, S5, S6, one could calculate the following calculation:

• 400-10% = 360

Mathematically, this input is absolutely not correct, but you could quickly do percent calculation. Typing the same "formula" in the calculator on the Samsung Galaxy S7, so you will gain:

• 400-10% = 399.9
