This is my second shot at CM7 on my Galaxy S GT-I9000. This time around I installed the 18.03 nightly build, which was the most recent available in the CyanogenMod repository and is also much improved over the 11.03 build that I had tried last time around. The improvements are very substantial, from a daily use point of view the difference is night & day.
As last time, I ll simply list out all of my observations and thoughts on CM7, starting with the positives.
- Since installation of the 18.03 build, CM7 is as stable as it could ever be. I ve had zero reboots and zero force closes of any application thus far. Skype runs fine on this build.
- The phone feels fast, really fast. In my use of the phone so far with CM7, I’m yet to notice any UI sluggishness. The screen ON/OFF animations never get old.
- The display gamma problem that I had alluded to in my earlier post is also fixed. My dark themed wallpapers look great.
- Other display glitches, like the screen not redrawing sometimes after a button touch(which leaves the pop-up in the middle of the screen slightly faded) are much reduced now. This used to happen quite often in the earlier build.
- All the other shortcomings still remain like the barebones camera, mediocre phone app, inability to record 720p videos, choppy 3D benchmarks in Quadrant(but still high scores). Auto-brightness is as before, screen doesn’t dim enough in low light.
- Last time I had not bothered to take any look at the battery performance of CM7 what with the instability and all. With the 18.03 build, I get manageable battery life. With few calls, a bit of surfing and having background updates ON, I get just about a days worth of juice out of it. Mind you, I’m sporadically connected by WiFi and usually tend to keep cellular data OFF, so the results are still a bit skewed. Also, keeping the phone idle with WiFi turned ON causes substantial battery drain – I observe about a 15% drop overnight. Not impressive in the least but I can live with it.
To me system stability and UI slickness are the most important factors while deciding on a ROM. Having a feature packed ROM which makes my phone feels sluggish or reboots once a day is no good.
Overall, therefore, I’m very impressed with CM7 and recommend it whole-heartedly to anyone who is on the look out for a slick Gingerbread ROM for their Galaxy S. Although still in Beta, it is stable and has just about enough battery life to be used on your primary phone. Things can only get better hereon for CM7. Now that the platform is stable, the developers of the ROM can focus on the 3D graphics driver and fine-tuning the ROM. And once the debug code is pulled out, the battery life should also be much improved.
These are exciting times – going through different builds of CM7 during its development and to see the great strides the development team is taking to bring out the most popular custom ROM in the Android world for Galaxy S. I cant wait for the day when the final build is officially released.

All the required files and builds for CM7 are available here. Enjoy installing it!
Update: After having used CM7 regularly over the past two weeks, another issue I ve come across is that when a call is answered, the calling party can barely hear me. I guess it has something to do with the microphone experiencing severe attenuation for answered calls. It works fine if I make a call instead.
