Hi @foxcode7, thank you for reporting! We have seen this issue before and it is caused by the developer option "Enable view attribute inspection". Please make sure that option is disabled. Also the layout inspector in Android Studio can cause this and sometimes a device can't recover from this state (you would have to factory reset it). As far a we could find and from our experience, this can only happen to developers, so users of a production app should be safe
