Samsung has changed my mind! Finally, I own once Galaxy S7 Edge that has been unpacked in Barcelona in February 2016. As you know, I have worked for Samsung company more than one year. It is neither short nor long time but enough for me to change my mind. I am going to tell you WHY IS THAT? Before that, I was a tester in Vietnamese Software company and I had experience in both kind of platform both Android and iOS. Honestly, during that time all Android platform really made me disappointed. When the Dev. team released each version app for testing, at that time I had to test this version for all devices which I had. I always detected more bugs on Android than iOS devices. In fact, Android OS is one of the most popular open-source operating system and is available on many different companies using different hardware. In other words, it is made in such a way that it can be used on multiple devices. So, it is really a big challenge. Android is as "tweakable" or "customizable" as iOS. This means that it can operate outside of it's fully tested configuration and can surface more bugs. During that time, I thought if I had money I had never invested Android for myself. And now everything has been changed. Samsung high-technologies has been researched and applied for smartphone that is very amazing. All of them convinced me such as design, convenience and technologies. Samsung Pay is one of them. It is the first mobile payment that's accepted almost anywhere you can swipe or tap your card. Add your credit cards, gift cards and even your loyalty cards and cruise through checkout. It makes transactions super easy. It also keeps your payment information separate and doesn't store or share it so you can pay without worry "No wallet. No worries". Now, I am waiting for a day Samsung Pay will launch in Vietnam. I hope that Samsung will have many great innovations in informatics technology and become the first company of smartphone in the world.
