This S20+ is quite delightful in the first few days. A lot of nice little things make this a great upgrade.
Pictures are quite good. The Live Focus seems a bit unnecessary in most cases as the natural bokeh provided by the lens does a pretty decent job. The pictures seem to have great color saturation, etc. Focus has been acceptable to me, seems a little slow on the draw in some situations. I find myself having the tap the screen quite often for it to focus on the right subject. The Single Take mode is pretty nice as I've tested it with the kiddos quite a bit. Not sure how much I'll use it in practice, but perhaps at kid parties and whatnot it'll be nice to have.
I realize that there was obviously something wrong with my S10+'s wireless charging as the S20+ has no problem using all my pads. I frequently had a hard time finding the sweet spot on the S10+ for "fast wireless charging" but the S20+ doesn't have an issue. I bet I had a failing or failed coil on my S10+ in retrospect.
Can't speak to use with the screen protector as I took mine off immediately, but the finger print sensor seems as fast as the S10+. Quite an adjustment to the placement of it, but muscle memory will adjust soon. I do appreciate the less curvature of the screen on the edges, makes edge swipes easier to do and app text doesn't get distorted on the edge as much (like SCP was bad).
The 120Hz screen and scrolling is just so, so, so smooth. I enabled it on all 4 of the phones I set up this week, so the users don't really know any different. They're all pretty impressed by the speed. I do miss the crispiness of the higher resolution but will not go back to 60Hz, ever.
I thought I would hate the button arrangement of everything being right side now, but it's far easier to deal with one handed. OH MY GOODNESS is Samsung being Samsung though with the Bixby BS on the power button. Obviously it can be disabled to be a regular power button, but for people like my 70 year old parents, this is a real confusion and something I didn't realize was even a thing until after I set up their phones. Who in the world would think the power button wouldn't turn the phone off??? stupid to have it to Bixby by default. Just go away Bixby, nobody likes you.
I still have some data issues leaving WiFi and hopping on some Sprint towers here in town, but I didn't think that was particularly a phone specific issue. I have had much better signal when on mobile data (we do not have 5G) and could even use it in the Mall last night which is an absolute data pit. Friggin dog ripped my down jacket sleeve (on accident) so I had to get a replacement!
As mentioned the vibration motor is quite nice and something you perhaps don't value until you have a nice one. Definitely nicer on the S20+ than the S10+.
A big improvement I see is the recognition of the voice-to-text on device. It's far more accurate and can hear me better in the car, which is where I need it most. Must have improved the top mic more or something, but overall great.
Battery life has been great, even in the first few days of phone use. I forget all the apps I need to exempt from the optimizing like bank apps and such to get purchase notifications, but slowly I'm getting it all set back up.
I'm not sure why Samsung didn't take the partition model of updates like the Pickle phones. Instead for system updates, we still have go through the blue android screen of waiting and the "optimizing apps". I thought that was an option for all Android OEM partners to use? Maybe it's Pickle specific, idk.
