i have a samsung s21 ultra dual sim model, but only use 1 sim, when connected to a wifi without internet connection, like a camera, or vacuum cleaner, the app installed in the phone does not switch to mobile data, even when the option is active in wifi configuration to switch to mobile data when wifi coneection is slow or inestable, in my old non samsung device it works fine, and in the iphone of my wife works fine, why in this brand new samsung device that option is not working?

i tried an option in network configuration where you add the app that use mobile data always but not working

when enter on wifi direct settings the device is not showed, i just connect to my camera as an access point, but is absurd that on my old huawei device i could connect to mobile network data connected to a wifi without internet access

i tried the option on developer option show as "Mobile data always active", but not working, even when the 4g icon is active when connected to wifi with no internet access, i thinks is a software related issue

i contacted samsung support, and they said that samsung does not do the things like other manufacturer, so they don't provide a solution, i cant use my video cam or configure my vacumm cleaner with my expensive S21 Ultra
