Galaxy S6 was my first smartphone, i didnt bother to get iphone 3g when it first came out It was fine at first, but i noticed some minor issues after using a few weeks, like: - bad auto focus when taking pic - it restarts itself secretly when im not looking - 6 months later, battery keep draining like shit, brought to samsung center, they said its common issue(yea google it), and replace a battery for me - another 6 months have passed, the battery problem came back, no longer under warranty, i had to pay for another battery, they said it will be fine after update - another 2 months, the battery problem happens again, i had to carry a brick size powerbank like an idiot with me all day for years
