Slim ICS Makes Ice Cream Sandwich on Galaxy S Pretty Snappy


Page content:

Samsung’s announcement a few weeks ago, that the original Galaxy S and its variants won’t be getting the official bump to Ice Cream Sandwich, seems to have had no effect on the rate at which  quality custom ICS ROMs are being developed for this phone. The latest on the block being SlimICS, a light, AOSP based custom Ice Cream Sandwich ROM cooked up by XDA developer krarvind.

The developer has stripped off quite a few apps, making the base ROM really light, just 73.2 MB, which is pretty good for an ICS ROM. Of course, he has also provided a link to a file containing removed apps & Google add-ons, should you want to flash any of them separately.

Have a look at the features, known issues & removed apps, below, quoted from the developer’s thread:

Built from AOSP 4.0.3 sources, with device folder and kernel from Team Hacksung


  • 5 Languages ( en ( us, uk), fr, it, de, es)
  • Zeam Launcher ( stock ICS launcher provided in addon package)
  • Basic Google Stuff Included ( 4.0.4 Gmail,Talk, Calendar and Contacts sync)
  • Market 3.4.4
  • Team Hacksung Kernel ( for now, flash any 4.0.3 kernel of your choice)
  • Rooted
  • Easy to customize.
  • 182 DPI ( use 240 for any incompatible apps or check here for market workaround)

What Works:

  • GPS
  • Bluetooth
  • Front and Back Camera/Video
  • 2G/3G Toggle
  • Wifi/Data
  • USB Tethering
  • Phone Call , they do need to work don’t they

What doesn’t:

  • Wifi Tethering?
  • You tell me

Removed Apps:

  • Email
  • Exchange
  • Galaxy4
  • Launcher2
  • OpenWnn
  • PinyinIME
  • QuickSearchBox
  • VideoEditor
  • Videos

Other Android 4.0 Ice Cream Sandwich Galaxy S Stuff

Btw, as you may already know, this is not the only ICS Galaxy S Rom available. Others being:

  • Cyanogenmod 9 – successor to CM7
  • Onecosmic’s ICS port – hugely popular and constantly developed by bunch of cool devs, and has been ported to other Galaxy S devices too, like Samsung Vibrant, Samsung Captivate, etc.
  • New AOKP Galaxy S Rom – A port on Galaxy S by Bhuvan, of the Rom made by team of devs under the Android Open Kang Project (I personally like this rom way too much, so would suggest to you guys too)

Do share you experience about SlimICS with us in comments below. And if you have also tried any other ICS rom, do compare them between each other and let us and other users know which is best according to you.
