Gapps optimized for mediatek
A-GAPPS 6.0 MARSHMALLOW -----> https://forum.xda-developers.com/android/general/gapps-gapps-6-0-1-minimal-t3276606
Installed the rom few days back.
working perfectly fine. the battery backup is wonderful.
I am primarily using this phone as a backup phone for my extra sim cards.
as this rom comes with gapps preinstalled, no need to install gapps separately.
I've wiped everything in TWRP and installed using the USB OTG.
