Featured ROM Review: The Grouper gets Liquid Smooth!

October 17, 2012 - Written By Alexander Maxham

Here we are, back with another ROM review. This time we’re talking Liquid Smooth RC5, which was just released on October 11th. As always, we’ve put it through our normal tests, and been running it for about a week or so on my Nexus 7. So let’s jump into the full review!

Name: Liquid Smooth V2.0 RC5 for the Nexus 7 (Grouper)

Description: Liquid Smooth is a custom ROM for a handful of devices (listed below), with plenty of customization. The development team behind Liquid Smooth has used some cherry picks from Cyanogenmod, AOSP, AOKP, Codename Android, and Team EOS. As far as battery life goes, it’s great on the Nexus 7 but we’ll get into that more in the battery life section below.

Available on which devices?

  • Samsung Galaxy Nexus (Maguro)
  • Verizon Galaxy Nexus (Toro)
  • Sprint Galaxy Nexus (Toroplus)
  • Samsung Galaxy S3 (I9300)
  • Sprint Galaxy S3 (d2spr)
  • Verizon Galaxy S3 (d2vzw)
  • T-Mobile Galaxy S3 (d2tmo)
  • AT&T Galaxy S3 (d2att)
  • US Cellular Galaxy S3 (d2usc)
  • Google Nexus 7 (grouper)
  • Samsung Galaxy Note (GT-N7000).

Opinion: I’ve used many custom ROMs in the past few months since the Nexus 7 hit my doorstep after pre-orders started shipping. And Liquid Smooth is my favorite so far. But it’s probably mostly because of the great battery life I’ve gotten from running this ROM. I especially like the ability to add a “kill all” button in the Recent’s tray.

Battery life: Battery life was great on Liquid Smooth. I didn’t flash any custom kernels, did not underclock the processor or undervolt it at all. I was about to get over six and a half hours of screen-on time. Probably could have pushed it to seven hours though.




  • Speed (5/5) –   Overall the ROM was pretty speedy, but as I said above I did not mess with the clocking of the processor so it probably could have gotten even speedier.
  • Features (4/5) – Nothing too much out of the ordinary. Something I’ve talked about a lot in my reviews is the ability to customize the softkeys, including which buttons are there, the color and more.
  • Theme (3/5) – It’s just the default Jelly Bean theme, but it does have the Theme Chooser, so any CM10-based theme should work fine on the device.
  • Development (3/5) – Doesn’t seem like there are new builds all that often. But when the ROM is this stable, who needs newer builds?
  • Battery(5/5) I was very impressed by the battery life on this ROM. I don’t think I’ve ever gotten that much on-screen time on my Nexus 7 with any other ROM or ROM/Kernel combo.
  • Overall (4/5) – Between the awesome battery life and great speed of the ROM, I’d have to give it an overall rating of 4 out of 5.


  • Plenty of Customization to go around, even for those that want extensive customization
  • Great Battery life
  • Android 4.1.2 on board
  • Very stable


  • Not many nightly builds, so crack flashers like myself will get bored quickly
  • Comes with stock Jelly Bean Kernel

Conclusion: Overall the ROM gave me a great experience and I’ll probably be running it for quite a while. Or until something new comes out for the Nexus 7, that catches my eye. Like I’ve said before the battery life on this ROM is amazing. Somehow Liquid Smooth has been able to put in more customizations than Codename Android, which I thought had a lot. So if you’re looking for a nice and speedy and battery efficient ROM, give this one a shot!
