Epic has revealed a number of updates headed to the mobile version of Fortnite, including the already released customizable HUD options and a release window for an Android version.
Voice chat is headed to mobile to allow you to communicate with teammates, even if you’re playing on a different platform. An on-screen button to mute yourself and other players is also planned.
The customizable HUD options allow you to rearrange and place the various on-screen buttons however you like. Buttons can be resized and their visibility can be altered as well. This change has already been implemented and was released in the most recent update.
