There are some instances in life where there is no trial run – when the time arrives, one has to bite the bullet and go through it. One example would be giving birth – you can have all the theoretical knowledge, but the day baby wants to make an exit from mother’s womb, then all of that theory would not offer much comfort. Other things in life, however, can be tested before the real deal, such as answering past year exam questions to get a gist of how things might be like. Another would be testing out a smartphone or tablet to see if it suits your lifestyle or not before making a purchase decision. Samsung knows this, which is why they have just introduced a 21-day trial program.
