And #my favourite is unlocking the phone with your face without even swipe Screen as I know till know in every rom we need to swipe the screen to apply face lock but in Cosmic we only need to wake the screen and just show a face that’s it. isn’t it cool haha I love this feature. By the way, its completely depends on your gapps package, I always use Micro not nano or pico and I prefer you to use Micro it comes with Gmail and face lock option or you can use any as you like.

        • LOS is simple and good , SOT is always different from user to use brother few are hardcore gamer user they hardly get 5-6 h Sot in any rom but generally normal user get max SOT

      • Latest NoS is buggy on whatsapp, it happens when you see video status.. The video is strecthed.. gotta see 4 your self.. moving on liquid temporary while waiting for latest Cosmic

  1. Hi Ranjan
    I think Oreo ROMs have a bit laggy scroll (also in status bar) .
    But I’m not sure.
    What you think?
    Is any rom without this problem?

  2. How to disable fullscreen keyboard on landscape mode sir? Like a liquid remix auto disable fullscreen keyboard. Sorry for bad english 🙁

  3. Stable rom !! No Heating , good battery , good performance , no network issues , so far so good !! Thanks Devs for these oreo roms .

  4. Excellent Rom

    I think this is the very stable rom in OREO, I am using since 15th Feb from released date, I am not encountered a single problem excluding video call.

    very smooth, nice camera, and excellent battery backup for me.

    please make more customizations like RR, CR, AEX roms, Thanks a lot for making a stable rom,

  5. Hey why my android when booting then pop up a lock screen where need a pin, then the keyboard is not out (bad English, thank you)

    • back to twrp. go to “advanced settings” and tap File Manager. go to data/system/locksettings.db.delete it and .key file too.

  6. Hey Sir, did you know what is the problem if my phone always rebooting after flash this cstom rom?

    my phone is on MIUI 8
    and android 6.x

  7. hy sir..
