Living with CyanogenMod 7 for Samsung Galaxy S

My phone, a Samsung Galaxy S, has been running CyanogenMod 7 for the past week or so. The first week was a bit rocky. The phone ignored vibration settings at first and would vibrate when ringing, and when I hung up. In one call I couldn’t hear the caller at all! It also ignored my ringtone setting and used the first mp3 on the phone (not so bad, it was a Fun Lovin’ Criminals track!)

Anyway, I practically had to upgrade. I was running an earlier version of the Voodoo rom which unfortunately didn’t behave. Wifi kept turning itself off and I used my allowance of 3G bandwidth a couple of times. I did try to update Voodoo but screwed up and had to do a factory reset. Thankfully I had a backup done with Titanium Backup! After restoring my apps I decided to take the plunge to CM7. Why? Gingerbread!

CyanogenMod is an aftermarket firmware for a number of cell phones based on the open-source Android operating system. It offers features not found in the official Android based firmwares of vendors of these cell phones.

Initially I installed the 7.1.0 RC1 but there were problems as I mentioned above. There are nightly builds however and they’re supposed to be fairly easy to install. I screwed that up too but eventually got everything working! I’m now running nightly #67 and things have been fairly smooth.

CyanogenMod 7 is a very good mod. My phone is flying along and while it does offer advantages over the stock kernel (updated more often plus other features) you do miss out on the excellent Samsung Camera app, and battery life is slightly worse. The FM radio doesn’t work either but I haven’t bothered to investigate that as I rarely use it.

Flashing a new rom isn’t for the unadventurous. If the idea of rebooting into recovery mode, possibly changing radio drivers and knowing you might run into a world of pain scares you, don’t do it! Gingerbread, the latest Android firmware for phones, is making its way to the SGS and if you haven’t got it yet run KIES and you may find it waiting for you. The advantage of using CM7 is that they can move to the very latest Gingerbread (2.3.5 at the time of writing, my phone company only offers 2.3.3). Nightly build #70 introduced that version of the OS. You might want to keep an eye on this thread on the XDA forums too. There are problems with the nightlies but of course most of those who have no problem won’t be posting there so you’re bound to see a concentration of negativity. #67 works fine for me. YMMV!

How fast is my Samsung Galaxy S now? I ran Quadrant Standard three times, with progressively better scores.

  1. 1612
  2. 1977
  3. 2015
For comparison, the original Samsung Galaxy S had a score of 750. I would be very interested to hear how the stock Samsung Galaxy S with the Samsung Gingerbread firmware compares.

It’s still not quite as fast as the Galaxy S with the venerable “One Click Lag Fix” I benchmarked a while back. That used EXT2 however, a filesystem lacking journaling features important to maintaining data in the event of a system crash or problem.

Would I recommend CyanogenMod 7? If you’re a techie and can live without the Samsung Camera App then yes. Go for it. If you’re an Open Source fan who hates proprietary software you should definitely go for it. You even have to install Google Apps separately because they are proprietary software!

If you just use your phone to take photos, check Twitter and make phone calls, then don’t go near CyanogenMod 7 (or any firmware TBH!) just yet.

  1. I upgraded to nightly #77 this morning, and then updated my bootloader from a Froyo one to a Gingerbread one with help from this post.

    My phone was charged fully and it feels like it’s not eating through the battery charge as fast as it did before. It’s been off the charger for more than an hour and battery is showing 97% which is quite good. Of course most of that hour was spent with the screen locked, and since I use Juice Defender Plus the 3G and Wifi radios were shut off.

    I have to admit, using heimdall to flash the bootloader was a little scary. First of all Windows had the driver for my phone installed 4 times already so I had to remove them and reboot. The touchpad on my laptop isn’t working right now after the drivers for it had to be reinstalled but I don’t care, my mouse is better!
