When Samsung unveiled the Note 9 a year ago, I was surprised by how much I liked it. Sure, it didn't bring many fresh features -- mostly just refinements in areas where the Note line already excelled. There was more power than before, longer battery life, a larger display and more built-in storage. Plus, some camera improvements made the Note 9 more capable in low light. These upgrades are pretty much a given with any new smartphone, though.
