      "reviewTitle": "Wonderful upgrade from the S21 Ultra! Display is good straight-on and up to 30% off-axis.",
      "reviewText": "SUMMARY: BUY IT! I didn't like any of the newer S series phones enough to buy until this one, plus the Android/OneUI OS updates recently ended for the S21 Ultra. \u2022 The S26 Ultra display looks great, better than the S21U, if viewed straight-on and up to maybe 30% off-axis with the privacy display off. I use my phone like this most of the time and have no need for the \"privacy\" feature, so a win. Farther off-axis though, or with the privacy display \"on\", the nicest thing I can say is \"it will do the job until the S27 Ultra is released with hopefully Privacy Display V2.0\". \u2022 The dithered 8-bit to make 10-bit display (Frame Rate Control tech) looks fine visually. I\u2019ve read that the iPhone 17 also uses the 8 to 10-bit FRC. A true hardware 10 bit or 12 bit display would take more power - Samsung would have to solve their small battery problem first. I'm hoping for a 10-bit to make 12-bit FRC display, with a much higher (than 500Hz) PWM display-dimming frequency to reduce eye strain, and at least a 7000 mAh silicon-carbon battery in the S27 Ultra - all 3 things as in current Oppo phones. :/ \u2022 The 25W wireless charging works so well that I can see I won't be using the 60W wired charger (EP-T6010NBEGUS) much. Same 25W rate as my wired S21U charging, but the S26U battery fills faster at 25W for some reason. The wireless charger puck\u2019s magnet ring strongly locks right onto my Otterbox Defender Pro XT case's (Amazon B0GD2KS743) opposite-pole magnet ring. The Samsung 25W wireless charger kit is labeled \"Magnet Wireless Charger | 45W Power Adapter\", a 25W wireless puck AND a 45W charger in the same box (EP-P2900TBEGUS). The puck requires the 45W charger (EP-T4511NBEGUS by itself), it says, even though it puts out just the 25W of charging power. The 15W wireless charging on the S21U was nearly useless (I even threw the pad away) due to no magnet for coil alignment and the lower charging rate. Problem though: no rubber strain relief on either end of the 25W puck\u2019s cable. It won\u2019t last over time, IMHO. \u2022 You can simply unplug the 25W wireless charging puck ^^ from the 45W adapter it comes with (USB-C), then use the wired charging cable in the S26U box to get a full 45W charging rate, about 2x as fast (real-world tested) as 25W! 2 charging rates in one box. :) The S26U display shows: \u201cSuper fast wireless charging\u201d for 25W from the puck; \"Super fast charging\" for the S21U's 25W wired adapter; \u201cSuper fast charging 2.0\u201d for 45W wired charging; & \u201cSuper fast charging 3.0\u201d for a wired connection with the 60W wall charger. I\u2019m finding the 60W & 45W wired chargers are charging at nearly the same rate if the battery is already mostly full. Seems the 60W rate would only happen (for a while) if the battery is very low. The 25W wireless & 45W wired straight cable S26U charging is really all many people would likely need, unless their battery gets full-cycled (mostly discharged) often, then the 60W would help. \u2022 The S26U's 5000 mAh battery is lasting much longer for a given time period than the same in the S21U, likely thanks to the higher efficiency of the 3nm Snapdragon SoC vs 5nm in the S21U. The charging battery-life-extender \u201cstop %\u201d setting in the S26U is adjustable from 80\u2013100%, vs. fixed at 80% or 100% in the S21U. Mine is set at 85% now. I can go to bed with 85% showing on the S26U, then wake up with 81% - and that is with the two cell carriers running (see below). Awesome. :) \u2022 The S26U uses higher 15V and 20V charging voltages than some past phones, such that it only needs 3A vs 5A of current, resulting in less bulky (than 5A) 3A charging cables. S26U 25W (S21U charger) = 2.77A*9V; 45W = 3A*15V; 60W = 3A*20V. Some older phones (S23 Ultra) used 5A*9V = 45W; so their \u201c45W\u201d wall adapter wouldn\u2019t give 45W S26U charging with only 9V & a 3A cable. The Samsung S26U 3A straight cords have nice rubber strain reliefs at the ends (3ft 3A = EP-DA705BBEGWW; 6ft 3A = EP-DX310JBEGUS). \u2022 The 45W USB-C port on the Samsung #EP-L5300 car charger works with the S26U 25W wireless puck (EP-P2900BBEGUS, puck w/o adapter) AND straight cable 45W charging (tested!). Plus it has a 15W USB-A port for something else. \u2022 App start-up & switching between apps is much faster and smoother on the S26U than the S21U, given the 2X faster performance SoC with better vapor-chamber cooling. App & OS updates go fast! Only having the UFS 4.0 on the S26U vs. the (pre-release rumored) latest 4.1 isn\u2019t making much difference. The 2nm 8 Elite Gen6 Pro SoC expected in the S27 Ultra is slated for UFS 5.0, twice the bandwidth of V4.0, and LPDDR6 memory. Will be a beast. :D \u2022 The dual SIM radios in the S26U work well! I'm now running Cricket (AT&T towers) on physical SIM IMEI1 and Spectrum Mobile (Verizon towers) on eSIM IMEI2. The S26U is fully set up for switching the call, messages, and data independently between carriers, sim1 and sim2 in the quick panel. The upper left of the lock screen shows \"cricket * Spectrum\" for carriers, and the signal strength bar adds a new row of dots underneath to show the signal strength of the other carrier too, plus showing both strength bars when the quick panel is pulled down. If you travel to different parts of town where one carrier\u2019s signal is much weaker, and/or has a \u201cfull tower load\u201d signal drop-out, and/or only one carrier has 5G mmWave antennas in an area (\"5G+\" display), and/or you want to use your data quota on a specific carrier, this is great. Two chances at getting a good connection. \u2022 Better weight/size distribution. Only 1 oz less (9 oz vs 10 oz), with cases, than the S21U, but the S26U literally feels 25% lighter, being slightly larger. Kind of a magic trick! \u2022 The Wi-Fi 7 works well as does the 6 GHz band. In my TP Link BE 550 Pro router/AP (from Amazon! B0DM6RF34J) I had to change the 6 GHz bandwidth from the default 160 MHz to \"mixed 160/320 MHz\" (or just 320 MHz) to have that band show as Wi-Fi 7 on the S26U vs Wi-Fi 6E (symbols for both on the display). I recently read that iPhones don't even have a 320 MHz bandwidth option on 6 GHz, so those users are apparently left with 6E on 6 GHz. \u2022 The S26U Wi-Fi switches between SSIDs VERY well, automatically, based on signal strength, when walking around a spread-out house with different wired Wi-Fi AP\u2019s, as is my case. The S21U usually didn\u2019t, requiring frequent manual SSID changes walking around. I\u2019ve noticed the S26U even turns the Wi-Fi back on when I get home (SSID recognition), after I\u2019ve turned it off while gone in the car. \u2022 The \"3D\" fingerprint reader on the S26U works very well! Nearly every time. That is without even turning on the new \"improve accuracy\" additional 10x scan option, too. The \"0D\" (lol) fingerprint reader on the S21U was useless, at least with my worn and scarred fingerprint. I gave up early-on with the S21U reader and used PIN codes ever since. The \u201cSamsung Pass\u201d app is usable now with its required fingerprint bio-ID. \u2022 I've shot some 4K and 8K video and it looks fantastic! Samsung's new APV encoding standard, a modern competitor to the older Apple Pro Res, is good with claimed 10% better storage efficiency. The phone will record 4:2:2 internally, supports Log recording, and can record to external SSD storage on USB via the port. 4K60fps APV 422HQ generates 12GB/min; 422LQ = 6GB/min. Hoping for a full 1\" camera sensor on the S27U! I love the natural \"true/accurate\" colors with the S26U cam vs. the processed \"happy bright\" colors of past Samsung phone cams. The S25 Ultra doesn't have APV, or the amazing new video Horizon Lock feature, so right there along with true color are 3 good reasons to get the S26U if you are a video fan. \u2022 The low light camera ability of the f/1.4 wider-aperture S26U main cam (vs. S25U's f/1.7) is also fantastic. I wind up with a *lot* of low light situations where I need to take photos. Couldn't do it with the S21U most of the time. I would have to use my large Lumix GH7 & GH5 MFT cameras with a fast lens. \u2022 The camera lenses do stick out in the back though, unlike the S21U where they were flat (and recessed with the S21U Otterbox Defender case). The S26U Otterbox Pro XT case mitigates that to some extent by having a plastic ring around the lens area that is slightly taller to help keep the lens from scraping on things when the phone is set down on its back. Lens protectors are a good idea (Amazon B0G7STMFKY). \u2022 The speakers/audio on the S26U can go a bit louder (and clearer) than the S21U, which was needed. Hopefully the S27U will support 32-bit float audio recording, like the Lumix GH7 cam and iPhone 17 Pro Max support, for zero concern over recording levels! Samsung really needs to update their new APV codec to support 32-bit float audio, like Pro Res can \u2013 this is a big Samsung omission, IMHO. :/ \u2022 The Bluetooth V6.0 in the S26U works better (stable, less lag, faster connect) than the S21U BT V5.2 with my car entertainment link (Lexus RX350) and PreSonus Eris 4.5BT desktop speakers. Unfortunately the S26U\u2019s SoC chip doesn\u2019t support the latest low-latency (Nov 2025) BT V6.2. I\u2019m hoping for that and a 10 Gbps USB 3.2 gen 2 port in the S27 Ultra like the iPhone17 has (S26U only has 5 Gbps gen 1 USB port). \u2022 The S26U adds Google Messaging via satellite connection to the emergency SOS satellite feature in the S25U, both only operational when no cell or Wi-Fi service exists. Spectrum Mobile does have satellite service via Skylo that comes included with the plans. I haven't been able to test since I always have cell & Wi-Fi around here. :( T-Mobile apparently offers S26U satellite via Starlink. The S26U allows up to 5 additional eSIMs to be stored & swapped out with the 2 active SIMs as needed. Future satellite-only monthly add-on plans (Starlink?) could be added as a (stored) eSIM 2. \u2022 The Samsung Smart Switch transfer app - the default that comes up when you power up the S26U - from the S21U took about 45 minutes to transfer 72GB of apps and data using the cable in the S26U box. The S26U had 69% battery out of the box, then the 45 transfer took it down to 55%. Keep in mind the SSS app completely re-installs the phone\u2019s apps from Google Play & Samsung Store, not just copying them over, then re-loads their data. Works extremely well! ZERO problem with the transfer, but of course passwords have to be re-entered everywhere. Any discontinued apps (I had one) or side-loaded apps have to be handled later, manually. \u2022 Can't comment about the AI/Bixby and stylus. I don't use either, maybe in the future. The S26U has a 40% faster NPU than the S25U, if you do use the phone\u2019s AI. Remember that Claude & ChatGPT do all their computes in the cloud, at data centers. They don\u2019t use a phone\u2019s (or PC\u2019s) NPU at all (at least currently). \u2022 And *great work* Amazon in getting the pre-ordered phone to me right on the promised March 11 release date!
