The latest OnePlus app to be decoupled from OxygenOS and moved to the Play Store is the OnePlus Game Space. It blocks notifications while playing, gives you quick access to optimizations like Fnatic mode and lists all installed games.
The latest version offers some additional functions. It comes with instant games. This feature allows users to play games without installing them first. Therefore, you can try out new games without the usual effort.
Another feature added to the app is Game Statistics. It shows the games you play most frequently and lists statistics on how much battery has been used by each game today and in the last week.
However, the app is exclusive to OnePlus devices. You can install the app by clicking here.
