I apologise if this has been answered but I can't find a reference to it, if so:
Do I need to be concerned by "this build was signed with public keys" and "SELinux is not enforcing"?
Is there any way to rectify this? If not, advice on what I should not be doing on my Tab A6 in order to reduce risk?
Grateful for any help.
You shouldnt be concerned. If you are not installing weird apk you will have no risk.
And even with selinux enforced you will have the same risk
