Greetings everyone! I tried finding a solution to the problem below in existing threads, but couldn’t locate one. Here goes… 1) In the Security settings of my Minix Neo X8H-Plus, I turned ON the option “Allow installation of apps from unknown sources.” 2) Tried to install an Android APK, but got the message “Install blocked. For security, your phone is set to block installation of apps obtained from unknown sources.” 3) I then went back to the Security settings and to my surprise, the option “Allow installation of apps from unknown sources” was turned OFF. 4) Tried again, but same result. The problem exists regardless of whether or not I retry the APK install. Any help would be much appreciated. Thanks.
