As a Roblox developer, it is currently too hard to intuitively test mobile device inputs within Studio.
A big problem with mobiles is that clicks will never be as precise as a mouse, and the emulator gives you the preciseness of a mouse, rather than a touch input. It also allows me to see how UI looks on a phone rather than through the emulator, though this isn’t as big of an issue.
Another issue with the emulator is that you naturally hold a phone with your two thumbs at the bottom, it’d be nice to test how reachable different buttons are from the phone directly, instead of a mouse (which removes this input problem).
If Roblox is able to address this issue, it would improve my development experience because I could start a team test session, then join it on a mobile device from a QR code or join code., to test mobile inputs more intuitively.
