Tweak the Adaptive Brightness on Your Windows 8 Device

Automatically adjusting the screen brightness depending on ambient light levels, also known as adaptive brightness, is a pretty standard feature on modern smartphones, tablets, PCs, and anything in between. This is most definitely the case for Windows 8 and RT devices such as the Microsoft Surface RT and Pro (check out the review here), Asus t100, and the Dell Venue 8 and 11 Pro tablets. But if you’ve been having issues with the pre-determined screen brightness levels of your Windows 8 device, or you’re simply not satisfied with them, there’s a fix that may help you out.

Developed by XDA Forum Member antys86, this tweak rids you of the default setting that only offers three brightness levels. As a replacement, it introduces a more flexible brightness adjustment that adapts to any light condition. The adaptive brightness changes according to the brightness level you’ve manually set, which means if the level is set at 0, there will be no automatic adjustment in brightness.

Additionally, the tweak shortens the time between adaptive brightness changes from three seconds to only 0.1 second (100 milliseconds). This will not drain the battery faster, as the tweak does not interfere with the sensor refresh rate. Rather, it simply modifies the time between changes in brightness.

This fix is easy to install, requiring you to simply download the provided registry key, run and confirm it, and reboot your device. But as always, make sure to backup your original registry key just in case you want to revert back to the original settings.

Samsung Galaxy S6 Edge Drop Test

The Samsung Galaxy S6 and Galaxy S6 Edge are already proving to be amongst the head turners of 2015. From favoring their inhouse Exynos 7 SoC over the Snapdragon 810 SoC (which ended up causing issues to its main rival); to ditching the removable battery and micro sd card slot in favor of a more "premium" device, the flagship duo have a lot going on for them at this stage. Regarding the premium redesign which replaced plastic with metal and glass,...
