Hello Rose,
which version would be recommended and is quite up-to-date (security level)? I honestly don't care about Android 10 or 11.
Do you know where these versions come from? The 4.24 there seems to be newer than 4.8, which makes it confusing.
sourceforge.net
It's built by a different developer and there are others like crDroid, LOS etc. also available. Magicxavi had reservations about the ROM which he had posted in the Havoc TG group : "Sadly i though there are nice new people started building for kenzo, i didn't check before pin the rom, that's my fault, but better late as never, so i WARN you all, the kernel used by default "bolt" contains some **** changes like PMIC (power manager IC) and other, and no commit history, whole kernel is literally 3 commits. So use it or not, make you own decision, but i WARNED you all about it. "
I didn't want to use Havoc A10 because of Permissive SELinux but in A11 iorap.cmd.compiler was a big hindrance draining battery and heating the device. If the device is rooted one can manually kill it but it comes back randomly sometimes multiple times a day. It was removed from AOSP codebase in 2022 so Havoc 4.24 is not afflicted with it. I used it for a few days and everything was fine barring the strange issue of Paytm app not working which is an issue for Indian users and deal breaker in my case. So I moved back to Havoc Unofficial 4.8. Havoc 4.8 doesn't use much more battery than 3.12 in my case if at all. In AEX 4.6 as well battery consumption had increased quite a bit which ultimately forced me to try A10 and finally staying on A11. I had to flash MIUI to fix an issue with sensors and in that battery life was much better so battery was still in good condition.
