Question:

Why does my mouse cursor lag when using the DeX for PC feature?

Answer:

The mouse cursor lag you're experiencing while using the DeX for PC feature is likely due to limitations in the event handling capabilities of the open source Android code provided by Google (AOSP). This issue arises when too many events are processed simultaneously, causing delays in the user interface. However, rest assured that Samsung is actively collaborating with our partners at Google to improve this situation in future versions of the Android operating system. We aim to provide the best possible experience for our users without any unnecessary inconveniences.
