Samsung Calculator is the standard application for performing different calculations on Android devices manufactured by Samsung. Once you launch this small app you will notice the straightforword user interface and you can start by making simple operations. The default mode has the calculator in a simple mode, but you can change it to a scientific calculator where you can perform complex calculations such as cosines, sines, tangents and more.
Even if you close the application while being in the scientific mode, after you launch it, the calculator will be back to simple calculations. The nice thing is that if you have the screen rotation turned on and you launch the application while having the smartphone in landscape position, this calculator will go straight into scientific mode. Another feature that helps a bit is the ability to clean the history of your operations.
There's not much to say about this simple tool. In case you need a calculator, this one is quite good and you can perform different types of calculations.
