I read through the linked article and an article on smex.org and there was nothing about "remote control backdoor access".

It complains about inability to uninstall from the manufacturers handset which is a manufacturers decision.

Again both articles manufacture controversy simply by nature that the Appcloud is associated with an Israeli company, not by what the app actually does or not by the fact that nobody forced Samsung to install this app on their handsets.

If you have information showing that Samsung is selling phones that are remote controlled by another government or corporate actor, that would be extremely newsworthy. Please share these news when you find them
