Update 1 (12/02/2020 @ 07:10 AM ET): OnePlus has renamed OnePlus Game Space to OnePlus Games. Scroll to the bottom for more information. The article as published on November 18, 2020, is preserved below.

Soon after OnePlus released its first Android 11 developer preview, the company started rolling out redesigned versions of its stock apps for older OnePlus devices. Over the last few weeks, the company has released updates for three apps — OnePlus Weather, OnePlus Notes, and OnePlus Gallery — all of which introduced the OxygenOS 11 design refresh. Now, OnePlus has started rolling out OnePlus Game Space v2.5.0 via the Play Store, and it too includes the new OxygenOS 11 UI.

As you can see in the attached images, OnePlus Game Space v2.5.0 features a new design that's more in line with the overall OxygenOS 11 aesthetic. Much like the OnePlus Weather app, it now has a lot of empty space at the top, and most of its UI elements have been moved closer to the bottom of the screen for easier access.

The game carousel on the app's home screen has been replaced with a simpler list, which shows an expanded card for the topmost game with two buttons — one to access settings like remove, uninstall, and shortcut, and the other to launch the game. However, the Game statistics page and app settings haven't received any major changes.

As mentioned earlier, the updated OnePlus Game Space app has started rolling out to users via the Play Store. But since our tipster is enrolled in the beta program, we aren't sure if the rollout is limited to the beta channel or not. In case you haven't received the update notification yet, you can manually check for it by following the Play Store link below. Make sure you drop a comment below if you've received the update on the stable channel.

OnePlus has renamed OnePlus Game Space to OnePlus Games. The announcement post goes on to detail some of the features of OnePlus Games, like the new UI, mis-touch prevention, notification control, and Fnatic Mode, but these have been available to Open Beta users for some time.
