The Xiaomi Focus Pen can not work in third-party games on the Xiaomi Pad 7 Pro because third-party games do not fully support smart pens. These games are often designed with traditional touch controls in mind, which means they can not be compatible with stylus input.
By default, the smart pen is disabled when game turbo is turned on. Game turbo helps enhance the gaming experience by optimizing performance and reducing latency, but it also disables features like the smart pen to avoid interference. To help ensure compatibility, game cloud control maintains a whitelist of supported games, which includes most popular titles from the Play Store. However, not all third-party games are included in this list.
