Good day. One of the first things you learn about shaders is that color values range from 0.0 to 1.0. This is known as 8-bit “unorm” color, because each channel has 256 color values, is unsigned (meaning no negatives) and normalized to the 0.0 to 1.0 range. Most of the time, we don’t need to think about this because 8-bits is enough for outputting colors to the screen. Sometimes, blending 8-bit colors is just not enough though. Today I want to show demonstration when you should care and what to

iPhone 17 has long-awaited fix for OLED screen flickering problem

9to5mac.com Ryan Christoffel 2025-10-06 15:33:59

Have you ever heard of PWM (pulse width modulation)? Even if you haven’t, this screen flickering issue still might impact you. But iPhone 17 looks like it will bring a long-awaited PWM fix. PWM can be disabled on iPhone 17 models I had never heard the term PWM before today, but as I learned by visiting the ‘PWM Sensitive’ subreddit—which has 16k weekly visitors—it’s a fairly widespread issue, and has been for years. Pulse width modulation is a tactic used by smartphones when brightness is red

Google is changing how Extra Dim works on the Pixel 10, and it’s so much better

androidauthority.com Unknown 2025-10-19 13:56:55

Joe Maring / Android Authority TL;DR The new Pixel 10 series integrates the “Extra Dim” feature directly into the main brightness slider, making it easier to access. This removes the need for a separate toggle, as Extra Dim now automatically activates when the brightness slider is at its minimum. While the feature was tested on older Pixels, it is currently exclusive to the Pixel 10, though it may come to other devices later. Google’s new Pixel 10 series introduces some surprise display upgr

Satellite Companies Like SpaceX Are Ignoring Astronomers’ Calls to Save the Night Sky

There are more than 12,000 active satellites circling Earth at the moment, a growing figure that has nearly doubled in less than three years. This recent boom in the satellite industry has been a major headache for astronomers, with bright satellites appearing as streaks in telescope images of the universe and tarnishing views of the night skies. A new paper reveals that satellite constellations are brighter than the recommended limits set forth by astronomers, with only one company adhering to

Android finally lets you control your Pixel phone’s flashlight brightness

Mishaal Rahman / Android Authority TL;DR Android has finally added native flashlight brightness controls from the Quick Settings panel. Google added support for controlling the flashlight brightness in Android 13, but there was no way to do so from Quick Settings. This feature is available in the latest August 2025 Android Canary release and may arrive in Android 16 QPR2.

This excellent Samsung Good Lock feature should come to all Android phones

Hadlee Simons / Android Authority Say what you will about Samsung One UI, but it makes a strong argument for being one of the most feature-rich Android skins on the market. That’s in large part due to the company’s Good Lock suite of apps, which allows you to deeply customize various aspects of your phone. The latest Good Lock app is Display Assistant, which was released at the tail end of 2024. After recently downloading it, I’ve discovered a feature I’d love to see on all of my future Androi

Honorable Mentions There are so many good TVs available, we can't add them all to our top list. Here are some great options that either missed the cut or got knocked off our top list by their replacements. Hisense U8QG: The U8QG (7/10, WIRED Recommends) is a great buy at its lowest price (around $1,000 for a 65-inch model) and a solid pick above that price, especially if you want eye-searing brightness above all else.

Robert Triggs / Android Authority Google Pixel 10 rumors are coming thick and fast these days as we close in on the launch date in just a few months.

High PWM (Pulse-Width Modulation) rates aren’t new to smartphone displays; we’ve already seen phones boasting thousands of Hz.

Pixel phones may finally get native flashlight brightness controls, years after Samsung and Apple

Mishaal Rahman / Android Authority TL;DR Google may add native flashlight brightness controls to Pixel phones in the next quarterly release of Android 16. While the hardware has long supported it, Pixel users currently need to use an app to adjust the flashlight’s intensity. The new feature, discovered in the latest beta, will likely make the Quick Settings flashlight tile expandable.
