Scope: Community-documented methods to access developer/engineering options on MG4 Electric infotainment (Android Automotive OS 9, MT2712), enable installation from unknown sources, sideload apps (notably Nova Launcher), and work around SAIC’s default launcher behavior. Differences between SE/basic and Trophy/XPower/higher-end trims are noted where known.
Safety & Warranty: Proceed at your own risk. Do not interact with the infotainment while driving. Some functions may be disabled by updates, vary by region/trim/firmware, or affect warranty.
Primary discovery threads: XDA starter post and MGEVs forum posts describing the keyboard-trigger trick and trim/version notes.
