I bought their flagship cellphone, hoping to see an amazing performance. Not only the battery life was notably shorter than my earlier/older/cheaper phones, but also it became hot easily and also due to its non-smart design, it was not possible to fit a glass screen protector on it. I was using it with a wallet-type case when I dropped it from 80 cm to ground and unfortunately, the screen hit some gravel particles and the glass on it shattered. I finally figured out that I could send the unit for repair to Samsung, for a cost equal to a couple of cheaper smartphones. I sent it on October 10th. I could not see any progress on my phone, until suddenly on October 30th I see in their website that they claim that they have delivered my phone to me. Obviously, they have not delivered it to me and I even checked my mailbox. There is no tracking number or so. I regret trusting Samsung with my money and I am rethinking my plans of buying other Korean products.
