What custom Android firmware is security-focused?

Question

Android

I don't like the constant holes in Android, but I really like its features. I don’t understand custom firmware, but I would like to read something about those in which security is primarily monitored, preferably without greatly infringing on the capabilities of Android and the availability of Google Play?

Answer 1

cyanogenmod, silent OS

Answer 2

What do you mean by holes? when you are asked:
Will you install the program? she asks:
and do you agree?

Answer 3

I just read the ordered articles by Kaspirsky on the mail

Answer 4

The presence of Google play is a huge security hole in itself. With such a requirement, custom firmware will not help much.
