Ten sposób chyba już nie działa, dostaję błąd:
"Processing changes to: Error: java.lang.SecurityException: Neither user 2000 nor current process has android.permission.MANAGE_USERS."
A na forum xda znalazłem cos takiego:
"Seems like with the latest security updates (Sept. 2016 and on) the pm hide/block commands can no longer be run successfully unless the device is rooted. Welcome to the new world order folks, unless someone finds a workaround without root"
