S26 series Fabruary 2nd update live india Version: S948BXXU1AZCF / S948BOXM1AZCF / S948BXXU1AZCF Size: 868.11 MB Security patch level: 5 February 2026

The Galaxy S26U uses CoE to improve efficiency, but its reflectance increased from 1.5% to 2.8%, making it similar to the current iPhone

Maybe I'm losing my touch, but I can't tell the difference between the aluminum on the Galaxy S26 ultra and titanium on S25 They feel basically the same

The Galaxy S26 Ultra supports 60W charging, but the cable in the box is only 3A. To get full 60W speed, you’ll need a 5A USB-C cable + separate charger.

The S26 Ultra eye strain: why this might actually be a High-Tech vision test. ​I’ve seen several posts these days followingthe delivery of S26Ultra. People are (allegedly) returning their S26 Ultra because of "instant nausea," "faint headaches," and a "cheap 3D" graininess. Some claim their old iPhone or S25 was fine, and other monitors are also fine, so "the screen must be broken." ​But I’m using mine perfectly. No strain. No headaches. Here is the truth: The S26 Ultra isn't broken; it’s just the first phone aggressive enough to probably expose vision issues you didn't know you had. ​To explain it clearly, my glasses are probably some kind of "S26 Armor" ​I have hypermetropia (farsightedness) and astigmatism. My prescription is +1.50 (left) and +1.75 (right) with a cylinder correction and anti-reflex/blue light coatings. ​If you’re struggling with this phone, it’s because the S26 Ultra has three "eye-stressors" that other phones don't: ​1. The "Privacy Pixel" grain (the 3D feeling). The S26 Ultra uses a world-first mixed-pixel architecture. It has "wide-angle" pixels mixed with "narrow-cone" pixels to support the new Privacy Mode. Even when Privacy Mode is OFF, those narrow pixels are physically there. ​So, if you have uncorrected astigmatism, your brain sees these different light patterns as "shimmering" or "fuzzy". My cylinder correction snaps these two light paths into one sharp image, killing that 3D like nausea instantly. ​2. The 480Hz "Samsung Pulse" where Samsung stuck with 480Hz PWM dimming on the M14 panel. While other brands use 2000Hz+, Samsung pulses slower. Because of that if you have hidden hypermetropia, your ciliary muscles are already "clenched" to focus. The 480Hz pulse makes those muscles "twitch" 480 times a second. My +1.75 power does the focusing work for my muscles, so they don't have to react to the flicker. ​3. Temporal Dithering (FRC) To get "10-bit" colors out of an 8-bit panel, the S26 Ultra uses FRC, which flickers pixels between colors faster than you can see. It’s "visual noise" that your brain has to filter out. My blue light and anti-reflex coatings act as a buffer, smoothing out that high-frequency noise before it hits my retina. ​So maybe stop roasting the phone and visit an optometrist. Yeah, I agree Samsung could do something about that PWM, but that doesn't cancel the fact that you might have vision issues that are just latent or undiscovered. ​If you can use a monitor but not the S26, it’s because a monitor is a "flat" light source. The S26 Ultra is a high-intensity, flickering, dual-pixel engine. It is essentially a diagnostic stress test for your eyes. Before I had a prescription and started wearing glasses, I had headaches and nausea and dizziness from certain devices also. ​If this phone gives you a headache, it’s a gift: it’s your body telling you that you probably need a prescription. 👓
