[Samsung Galaxy Nexus] Galaxyninja66:
I remember wanting to write a continuously updated guide like this back in 2016 When I was running CM9.1 on my old AT&T Fusion 2 (3.5" TFT, Snapdragon S1, and yes, this was 2016)

I tried out kitkat on the Gnexus and it was alright, slow but alright. However, I bought this phone to run ICS on and that is damn well what I plan to do!

Now first thing is first, the OLD CM9.1 (Android 4.0.4) CM link: https://web.archive.org/web/2014100...d.org:80/get/jenkins/7070/cm-9.1.0-maguro.zip

Also Gapps (old school ones too!): https://devfiles.co/download/4DW4yYPf/gapps-ics-20120429-signed.zip

And now for the list of tips from me!

First of all are my display settings. What I noticed that CM9.1 has that CM11 did not was the Galaxy Nexus display tuner settings near the middle of the menus.

Display Settings I use:

My settings are as follows:

Color multipliers is set to - Dark Sett.

Color gamma is set to - CM Sett.

Color Hack Presets is set to - Nothing, when I change this is ruins my settings

With these options colors are much more punchy and dark.

Performance Settings I use:

Governor - Conservative

Min freq - Default 320Mhz

Max freq - 920Mhz

IO Scheduler- not available in stock options, it is most likely CFQ

16Bit transparency and surface dithering are off, as are memory management options. This is just my preference, but you may enjoy them on.

Kernel is the default, stock CM9.1 kernel.

Attached is the stock Galaxy Nexus rainbow wallpaper, or that one you see in all the stock photos. Can't find that blue bubble one anywhere : (

Battery usage/life:

I am a light user, by all meanings of the word. End of day my SoT rarely exceeds 30 minutes, let alone a couple hours. I rarely play games and most of what I do on my phone is text, and check the time. Sometimes I make calls and take pictures but for most things I use my Nexus 10. As of writing this my Galaxy Nexus is at 48% after me pulling it off the charger at 7AM, and right now at 5:51PM. My SoT as of now is 41 Minutes. Attached are the two screenshots confirming this.

Finally, app support. Last on the list because of length. You are going to be using apk mirror for the majority of this. Some links to old apk's that somewhat function are listed below, along with ones that are confirmed to be some how dysfunctional. As with all things, your mileage will surely vary.

List of apk links to old apps:

Instagram 7.10.x (4.0.3+ - I had issues, you might not. It loaded a bit then crashed) https://www.apkmirror.com/apk/insta...ease/instagram-7-10-0-2-android-apk-download/

Greenify 2.7.1 (4.0+ - works fine so far) https://www.apkmirror.com/apk/insta...ease/instagram-7-10-0-2-android-apk-download/

Spotify 3.2.0 (2.3+ - Crashed at start up, but seemed to work on all other devices where the latest didn't work. Also some people prefer the old spotify) https://www.apkmirror.com/apk/spoti...ease/spotify-3-2-0-1197-android-apk-download/

ES File explorer 4.0 (2.0+ - Classic ES file explorer, before they added all that new stuff that bogs it down) https://www.apkmirror.com/apk/es-gl.../es-file-explorer-4-0-0-android-apk-download/

Twitter 5.95 (4.0.3+ - Old but not ancient twitter, should run well on the Gnexus) https://www.apkmirror.com/apk/twitter-inc/twitter/twitter-5-95-0-release/

This list is meant to expand as apps are updated and people link apk's they are currently using!

I do plan on expanding this post more as I get more at home with CM9.1 and my Galaxy Nexus, and with anything anyone links or shares with me! :)
