Is your Android phone secure? President Donald Trump’s favorite smartphone reportedly is an older Android device. Security concerns flared recently, following indications that he sent some tweets from it. Of course, the president has been given a special secure device, but it’s not clear whether he is using it. My question is, if the president is not secure using an ordinary phone for his primary wireless communications… are any of us? This is the same security dilemma President Obama faced when he took office eight years ago.
