Out of the many features that the Pixel 4 has to offer, one of the most popular features is the “Smooth” 90Hz display that Google now offers on both of their flagship devices. We began to see phones with smoother displays beginning with Razer Phone, and then became main stream when it hit the iPad Pro. More mainstream phones began to carry higher refresh rate screens as of recent, with the OnePlus 7 Pro being one of the most recent Android phones to carry that type of screen.
Google knew this would be something that people wanted on their phones, so they added it to their new Pixel 4. Google has made many surprising decisions when it comes to the Pixel 4, like the battery size and no wide camera, and it looks like the display has another surprise as well! Kellen over at Droid-Life.net, has been noticing while using his Pixel 4, the screen drops from 90Hz back to 60Hz when using the phone under 75% brightness.
This isn’t great for the Pixel 4 at all, since the older OnePlus 7 Pro doesn’t with its display no matter what level of brightness you have it on, which proves that it is not a hardware limitation. Hopefully Google is able to fix this through a Software Update, being that Google doesn’t need any more negative slack for their Pixel 4. For now, check to see if when you Force 90Hz through developer settings, it doesn’t drop.
