    Fast - Thin - Powerful

    #1 - the screen recorder is excellent & the editor is great. #2 - the ability to take UHD images that allow you to put on acrylic is pretty sweet. I got the 12ram | 128. You need to get a large sim card. If you take pics in 108mp mode and shoot in 8k, you'll drain quick. I'm a nerd, this thing is awesome and worth the 1.5k. Questionable: i have 12gigs ram, but it runs with 3.8-4.5 regularly.

    Great phone once you get past the flaws & hype

    Here's the truth about the GS20 Ultra...it was marketed on gimmick features instead of the core features and I think that was a mistake. The screen is great, the battery life is great, it's fast, and the cameras are great with an *. The core features shine but the gimmicks are where this phone comes up short and that's why reviews are mixed. Here are the cons: - Great screen that makes watching videos and movie content look amazing. Best screen of any smartphone. - Great battery life if you turn off the 120Hz refresh rate and use the highest resolution. - The new Snapdragon chip makes this phone fast and smooth. With plenty of RAM I've had no slowdown or lag. - The cameras take great pics that show lots of details. I gave the cameras an * though because I'm not a person who zooms in when taking pics. So far the zoom pics are ok but not as good as advertised. - Comes with the ability to get 5G service. Right now 5G is very limited though and hard to find. Cons: - The price of this phone is very high and probably a deal breaker for most. I was given a $300 trade in plus a $300 store credit. Without those discounts I'd pass on this phone. - Too many advertised gimmicks that fail to live up to the hype. 100 times zoom photos are grainy and bad, 8K videos can't be seen in 8K unless you go buy an 8K TV, and the 108MP photos barely look better than the 12MP photos. The 120Hz refresh rate is cool but after 2 days your eyes get used to it and you don't notice it. The iPad Pro has a 120Hz screen but it doesn't make 60Hz screens seem "slow". - Only available in 2 colors right now. - Samsung is slow with bug fixes and software updates especially compared to the iPhone. A new iPhone always has access to the newest and most current version of iOS but new Samsung phones don't get the newest version of Android for 6 months so they tend to run old Android software. Bottom line...buy this phone for the screen, battery life, speed, and cameras but don't buy it for the advertised gimmicks and "special features". I own the iPhone 11 Pro Max also so I have no bias and focused on the user experience instead of focusing on which phone is "better". By the end of the year this will still be the best overall Android phone and that matters when you are paying this much for a phone.
