S9+ -- mini overview from my own use:
The S9+ SD 845 model G965U1 Coral Blue, no case yet. Disabled most google apps/services except play store and photos. Using bk disabler disabled many of samsung bloat software and certain features I do not use, like the Edge panel, Samsung pay, etc.
Battery life is excellent. I have a minimalist AOD always on and SOT is at about 5hrs, 2 Exchange accounts, 3 tapatalk accounts, mms/sms/handful of phone calls, web surfing, youtube usage a bit, and about 10 Groove tracks played more or less. Now with total time off the charger of 19hrs or so and I have 34% left.
The display is as we would expect. Samsung uses a proprietary driver I believe along with their display service(s) and panel, and the brightness and color modes compliment each other well. The Sunlight readability is pretty good. But I have not assesed all the panel configurations to see which is optimal for my use/needs. It has done some buggy things though, like prior to the latest OTA update night mode was funky and super orange. It would kick in a couple seconds after unlocking the phone each time I unlocked it while enabled, meaning it was turned off at unlock and turned on after the screen got settled. Another is that more than twice I have unlocked the phone during the day and Autobrightness crapped out and the display was completely dim and would not adjust to a readable brightness.
The Sound from this thing is top notch. The stereo speaker setup and dolby atmost are just great. I thought the Idol 4s was nice and the most acurate with sound reproduction (without and EQ mind you) but the way Samsung did theirs and combined Harmon speakers just works excellently. And you can crank it loud with little distortion. Off the 3.5mm wire I am still trying to get what I think sounds good to my ear but so far the quality and range are excellent.
Call quality is great and it has used Wifi calling mostly. It is fast and snappy. The UI works for me. I download a dark them called sd-Black by aire design and it reminds me alot of the Windows Phone UI now. The finger print sensor is fast and accurate. Samsung has a ton of goodies baked into the OS that I am not sure I have looked at even half of them thorougly. I kninda like the one handed mode double tapping the home button 3 times, but it is not ideal imo. I can provide more detail on that if anyone needs...
The camera is pretty good. I have not fully used it enough to know how to use it quicky and fluidly. I need a case to be able to hold it appropriately and safely when trying to snap photos. However the few that I have taken are good. In low light it is a good shooter too. I have not really used the camera though to make a complete judgement from y view but it works really well and for my average camera usage it is good. I like that it uses a motion photo feature like living images for photos you take.
The phone is a bit thicker, heavier wider and a bit shorter than the S8+. It feels easy to use and should be even better once I get a case. I ordered a spigen liquid air armor case.
The one thing that is really impressive on it so far is the battery life. I did disable a lot of stuff. But compared to the s8+ with the same battery size this is good. It should be expected from the SD 845 anyway right?. IMO the standby drain is where I think it excels the most and why the stamina is so good when it needs to be in use.
It really is a great device to use for me personally if moving from a Lumia. I just hope Microsoft has an Andromeda-like device lined up soon that can replace this hunk of glass though (sorry just had to say it). Am hoping what they want to do with their new device will be something I and others can use and need for our daily lives to replace devices like this most were forced to move to. I moved off Google entirely except gmail and was happy for several years. Now I have to embrace it a bit more unfortunately. I have not decided what I will do with all my Lumias yet. I will try to provide more about my use with this device as it progresses.
