    Awesome! Left Apple for good

    Beautiful phone, very smooth and fast. Best camera on any phone period! Battery life seems great, I literally didn’t sit this thing down yesterday and the battery was still going at 1 am. I also think it has the best display on any phone right now. The ar emoji is nothing more than a gimmick but so is apples soo. I’ve been an Apple guy since the iPhone 4 and just had a iPhone 7 that I traded for this, I wasn’t about to get the iPhone X, IMO Apple has been going down hill since Jobs passed away, no new innovation or quality control there anymore. My iPhone 7 was so buggy. I was a little nervous at first but after setting it up for a day, I finally have it the way I want it and love it. Android is different in every way, but I love the customization. If you’ve been thinking about switching like I have been for a year,don’t hesitate on this one you won’t be disappointed

    A Perfected Samsung

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    I have had many Samsung phones, including the S8+ right before this one. I decided to upgrade and turn my phone back into my carrier to get the newest one. I would say this is not a necessary upgrade if coming from an s8, but, this phone is much more than meets the eye. Samsung took customer feedback into consideration and changed a few but crucial things. Fingerprint reader has a much better location. Stereo speakers sound amazing (although not the best out there). The display of course is the best ever on a smartphone. They kept a headphone jack! The 6GB of RAM paired with the need 845 chipset is a noticeable improvement and mitigates some of the laggy Samsung UI problems. A few features in Oreo that I've been using for years were removed so that's a tad frustrating. I hope it's fixed in future updates. I went bold and got the lilac color. I usually get black, but I'm really enjoying the lilac. It's beautiful and is a welcome change Overall, if you're already a Samsung fan you will love this device. It's no pixel 2, but they did an impressive job. I would rate an 8.5/10

    Best Android Phone Today

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    This phone is arguably the best Android smartphone that you can buy today. It's like having a very portable, network-connected computer in your pocket. Plus it has a superior camera to other phones and most point-and-shoot cameras, and it has a superior screen display. I use the camera, Wifi, and Skype extensively when traveling abroad. My only beef (a minor one) is that there are so many apps and options, the processor is so fast and the screen is so sensitive, that you can inadvertently open unintended apps and features. It takes a while to become accustomed to all its features and to customize them to your preferences. BestBuy sometimes has the best discounts. You should also buy a high-quality protector case and screen protector to protect your investment.

    Solid Smartphone

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite Plus MemberElite Plus Member

    I am coming from an S8 so the upgrade wasn't a huge one for me. But I will say, like the S8 this is a great phone. It is a bit faster and I do get better battery life on the S9 even though the battery is the same size. Guess that is some of the power consumption optimizations made to the Snapdragon 845 and Android Oreo. For the most part with a custom launcher you can get an almost vanilla Android experience. The biggest compliant is the Bixby button. If Samsung insists on putting this on all of their phones they could at least let us remap it to something else like the camera or flashlight or something useful like that.

    Samsung Rocks

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    Samsung got this one right -- like the ones in the past. I love the layout, I love the feel (a little more 'solid' than the S7 Edge I moved from) and the speed and memory is good. I wish the battery would last longer. I get 10 hours or so on a single charge. The new charging port (mini-USB) is a pain as no cord I already had will work. And I can't use the same cord to charge my bluetooth and my phone -- now I have to carry around two charging centers when traveling -- I can see me losing one or both with each trip.

    Better than expected

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    I upgraded from an LG G6 and I was reluctant to purchase because of the similarities to the s8, but upon purchase I got the s9 but I found s9+ better fitting in my hand. In terms of my reluctance I'm happy to say they made it new enough that I dont feel like I should have waited another year. The camera is amazing, as expected and the small new features and aesthetic updates are pretty useful. Battery is great, everything is great. I'm very happy with my phone!

    Simply amazing flagship phone!

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    I finally upgraded from the S6 to the stunning S9+ and I am so glad that I did! I had to choose between the 9 and the 9+ and RAM and dual camera made the decision for me. It's very quick, apps open like lightning. The camera, for the small amount I've used it, is stunning! I was so impressed with the low light pictures and the 2x optical zoom with no graininess or loss of quality. Super slick interface and the latest version of OS, Oreo. My S6 lasted 3 years, I expect this will do the same.
