LG G3 w/ Android 6.0 Marshmallow Antutu Score: 56,071

This ROM will give you a beastly performance, I got 56,071 on Antutu benchmark test, which is unreal for an LG G3!  Besides benchmark numbers, the ROM runs super fast!

Overall, this is an excellent Marshmallow ROM that will give you latest LG G5 software features, Android 6.0 Marshmallow, root, and customization.  So definitely give this ROM a go this week(end) and do let me know what you think!

    How does Fulmics 5.0 compare to Cyanogenmod 13.0?

    • Simon says:

      It’s better, much more stable and actually faster, against all my expectations. The biggest boost is in battery life though, I get at least an hour more of SOT.

  3. Ian Tuite says:

    Hi

    You say on your site above, that “No Gapps required for this ROM!”
    but further on down it says ‘if you don’t have Google Play Store’ to download it from ‘the post above’.
    ???? I don’t see it.
    Do you mean the Google Play Store fix is in the ‘3G/4G LTE Fix’ post ??

    I love Fulmics ROM on my G3 (D850). The ONLY issue that I currently have right now for the MM ROM is that you have to install Fulmics 5.1 and get your phone configured and then download and flash Fulmics 5.2-5.3. Other than that, it’s a great ROM.
