Havoc OS

Havoc OS Android 10 is based on Google’s AOSP, inspired by Google Pixel. it comes with a clean UI while offering many features that you probably won’t find in any ROM. Havoc OS also comes with a theme customizer that lets you theme your device UI and other performance tweaks.

Havoc OS is the first stable Android 10 ROM for Tecno Spark 2 KA7 that I have booted and works pretty fine.


Well, as you may already have guessed the new Android 10 ROM for Tecno Spark 2 comes with a few bugs which you’re already familiar with. Hotspot and offline charging seems to be the two major bugs in this ROM and other minor bugs which wouldn’t interfere with the ROM overall experience.

You may notice some glitching on the status bar when pulled down too, that would be fixed in coming updates. If you haven’t rooted your device already and would love to install the new Android 10 custom ROM, download TWRP for KA7 and root your device.
