INFO

First of all its being quite a journey with this device....And my first thanks goes God.

We are all by now aware that our device Samsung galaxy j4+ comes with the msm8917 chipset which supports the 64bit architecture by default. Samsung however in their own wisdom decided to bring an arm32 phone to our doorsteps( probably due to 2GB RAM but shouldnt hurt much). It has been my dream and that of many others users to enjoy benefits which arm64 provides. some of these benefits are using ported arm64 apps like gcam, custom face unlock and certain apps only support 64bit functionality. We have also noticed arm64 is slightly faster. Well the journey is partly over... This work wouldnt have been possible with me alone since I used ideas from other devs. Great thanks to

ataberkozen for original arm device trees and other fixes. Many thanks to all testers and all supporters.

If you love my work or me:D you can grab me a drink at donate section

ADDITIONAL INFO: ROM has vendor partition in system due to lack of space on vendor partition and inability to resize it due to bootloader bottlenecks dont expect to boot gsi.

Havoc-OS 3.x is based on AOSP, inspired by Google Pixel.

Has a refined Material Design 2 UI crafted by [MENTION=7578917]SKULSHADY[/MENTION].

So many features that you probably won't find in any ROM.

All you can dream of and all you'll ever need.

Just flash and enjoy...​
