[Samsung Galaxy S23 Ultra] smitel:
Where I'm now, in SamsungSystemSupportEngine.log I find the following:

[23-10-21 18:56:16][DBG]SamsungSystemSupportEngine CallbackEx Message:[{"ModuleType":"EasyConnect","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"EasyConnect","ActionName":"GetOnOff","ActionValue":"","ReturnValue":""},{"ModuleType":"BestAP","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"Wired","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"MbnNetwork","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"MbnNetwork","ActionName":"GetValue","ActionValue":"","ReturnValue":""},{"ModuleType":"ContinueApps","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"SamsungMultiControl","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"SamsungMultiControl","ActionName":"GetOnOff","ActionValue":"","ReturnValue":""},{"ModuleType":"System","ActionName":"SupportComputerInfo","ActionValue":"","ReturnValue":""},{"ModuleType":"DolbyAtmos","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"DisplayColor","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"DisplayColor","ActionName":"SupportColortone","ActionValue":"","ReturnValue":""},{"ModuleType":"DisplayColor","ActionName":"SupportDPST","ActionValue":"","ReturnValue":""},{"ModuleType":"DisplayColor","ActionName":"SupportColorMode","ActionValue":"","ReturnValue":""},{"ModuleType":"Amoled","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"DisplayLace","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"Amoled","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"FocusMode","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"ConsultingMode","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"KeyboardBacklightLevel","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"KeyboardBacklightLevel","ActionName":"GetIdleOnOff","ActionValue":"","ReturnValue":""},{"ModuleType":"KeyboardBacklightLevel","ActionName":"GetIdleTime","ActionValue":"","ReturnValue":""},{"ModuleType":"KeyboardBacklightLevel","ActionName":"SupportALS","ActionValue":"","ReturnValue":""},{"ModuleType":"BatteryLifeExtenderPlus","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"USBChargingS3","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"USBCharging","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"PerformanceMode","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"PerformanceMode","ActionName":"ModeList","ActionValue":"","ReturnValue":""},{"ModuleType":"PerformanceModeV2","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"PerformanceModeV2","ActionName":"ModeList","ActionValue":"","ReturnValue":""},{"ModuleType":"BeautyFilter","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"AutoBoot","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"QuickSettings","ActionName":"Support","ActionValue":"","ReturnValue":""},{"ModuleType":"System","ActionName":"SupportComputerInfo","ActionValue":"","ReturnValue":""},{"ModuleType":"System","ActionName":"Version","ActionValue":"","ReturnValue":""},{"ModuleType":"DisplayColor","ActionName":"SupportDPST","ActionValue":"","ReturnValue":""},{"ModuleType":"BlockCamMic","ActionName":"Support","ActionValue":"","ReturnValue":""}]

For a few of a the modules I see "DlgSamsungSystemSupportEngine CallbackEx ModuleType= EasyConnect ActionName= Support ActionValue= ReturnValue= " so it seems like it's not iterating over the entire array. And then in SamsungSettingsApp.log I see "

|Debug|22084|1|SamsungSettingsApp.Model.RequestDataHelper.GetOnOff|Invalid Param : SamsungMultiControl

" for most of the parameters.
