[Galaxy Grand Prime Original Android Development] Alando123:
Havoc-OS is an all new ROM based on LineageOS.

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

Just flash and enjoy...

General:

System-wide Rounded UI

Spectrum support

Razer Phone lock/unlock sounds

We'll not support users and answer questions from users which:

are running a custom kernel

have flashed mods

modified system files

didn't follow our intructions word by word

are unfriendly

And most important: DON'T READ THE OP

BUGS:

Same as Lineage OS 15.1

Turning on AutoBrightness disables the adjustment of brightness manually, even when turned back off; To fix this, download this app from here and play with the brightness adjustments for about a minute then reboot, you can uninstall the app once brightness adjustment is fixed in statusbar (CONFIRMED FIX)

Another fix is Settings-> Havoc Settings-> Status bar then enable Brightness Control then in Settings-> Havoc Settings-> Quick Settings change Brightness slider to "Hide" option, then you will be able to slide your finger across the status bar to adjust the brightness. (CONFIRMED FIX)

Changing system font in Settings -> Havoc Settings -> Interface causes bootloop

[NOTE]:

If you couldn't take screenshots, go to /system/vendor/lib/hw, make a backup of android.hardware.graphics.mapper@2.0-impl.so somewhere else, then delete it from this folder

The camera preview will freeze and you can't capture or record after this. To restore original camera function (but will derp screenshot again), restore the backed up android.hardware.graphics.mapper@2.0-impl.so again to /system/vendor/lib/hw

First time installing Havoc OS to your Galaxy Grand Prime, or coming from another ROM?

Install latest TWRP Recovery MUST USE VERSION 3.2.2-0 OR ASSERT ERROR OCCURS

Reboot into Recovery using 3-button-combo (Vol-up+Home+Power)

Do a Nandroid backup! (Optional and only if you weren't running TouchWiz before)

WIPE (wipe data/factory reset + wipe cache partition + format /system partition)*

Install the ROM from sdcard using TWRP Recovery

Optionally install the Google Apps ( get it here: https://opengapps.org ) (pico GAPPS recommended) (*)

[NOTE]:

If you're about going to install GAPPS with ROM, install it right after you've installed the ROM, else you have to do a factory reset if you've booted the ROM first
