I am looking for an app for remote control of a device. Something looks like Google Family Link, which also allows remote direct control of the target device. It is not for my children (aka parental control), but for my elderly parents who are not so tech smart (aka to avoid and preventing any threatening from the net).
The controller device will be a Samsung Galaxy A71, the target device will be a Samsung Galaxy A02s. Either are equipped with Android 11. So a specific Samsung app would be suitable.
