Google has artificially limited the brightness of the screen on the Pixel 4. The remedy involves going through the ROOT process

Launched to demonstrate the best of the Android 10 platform, Pixel 4 phones do not quite meet expectations, using them to reveal all kinds of problems and compromises, to the disappointment of fans.

Unexpectedly long for a premium range product, the list of grievances touches on the most diverse aspects, such as the security of face recognition, the wasted potential of radar technology sensors used for gesture control detection, and how Google has chosen to

For example, the Pixel 4 series features HDR technology and native support for a 90Hz image refresh rate (compared to 60Hz on regular screens), promising slower playback of moving scenes. and improving reaction time in Android games. But the technology called Smooth Display has been implemented by Google with a view to saving the battery, the mode of operation assuming dynamic switching between the refresh rate at 90Hz and the standard 60Hz, if the running application does not require a high level of performance. According to the users, the transition is made in a chaotic manner, over a certain level of brightness the screen remains in 60Hz mode.

While the first screen problem was solved with a firmware update, another continues to dissatisfy users who are trying to watch HDR clips. Apparently, the screen of the Pixel 4 phones achieves by setting the maximum brightness a brightness of about 450 nits, almost half of the level offered on flagship models delivered by Samsung and Apple. Looking for the source of the problem, members of the modding community found that Google inexplicably limited the maximum brightness of the screen, far below the phone's hardware capabilities.

In the absence of an official firmware update to permanently remove it, the limitation may be lifted. by entering text commands, accepted only after unlocking the Android version using the ROOT process. The result is a brightness of up to 610 nits when viewing HDR clips, the change for good is easy to spot. Unfortunately, the change only remains until the screen is turned off, so it cannot be considered a permanent solution.

The ones presented above unfortunately lead to another pain point on the list of grievances – the mediocre autonomy of the battery. Thus, even with the screen brightness artificially limited to 450 nits, Pixel 4 phones only offer about 4 hours of continuous screen time, or about one day of battery life.
