1148100 2010-10-27 07:56:00 So I've finally purchased a Samsung Galaxy S, and I absolutely love it - jaw-dropping SAMOLED screen, Android 2.1 is a joy, and now that I've applied the lagfix that changes the filesystem from RFS to EXT4 it's blisteringly quick; stock benchmark score on Quadrant was around 830 - now 1677.

GPS is still a bit on the slow side, but that should be fixed with a firmware update.

Roll on Android 2.2!

So has anyone else got one of these?

...changes the filesystem...to EXT4...
This is likely to significantly shorten the life of your SD card - ext4 is a journalling filesystem.

I strongly recommend you use something like ext2 instead.

Yes, the nice chap in the Vodafone store tried to sell me one after he'd discovered they had no Galaxy S's in stock. :p

Just out of interest Erayd, could you explain exactly what the following quote from the Project-Voodoo lagfix site means:


Galaxy S hardware is different from previous generation’s Android phones.
To extend /data partition, the place where all your apps are installed and personal data are stored, Samsung use 2GB from the internal SD card.

There’s nothing wrong with this approach, but they use the proprietary RFS filesystem they build as a legacy FAT, adding journalisation and POSIX permission. Both are required to run safely Android.
Unfortunately, this filesystem tries too hard and don’t provide a consistent experience with many applications installed or a few days uptime.

And here comes Voodoo lagfix to the rescue :)

By replacing the faulty RFS filesystem with the Linux-standard Ext4 filesystem,

I see references to journalisation and POSIX-permission a lot, but have never really got a succinct answer on their meaning or importance.

Among other things, they require user/group owners on a file, and r/w/x user/group/everyone permission bitmasks on inodes.

Journalling is a method of maintaining filesystem consistency without requiring a full verification of the filesystem contents every time fsck is run. It's essentially a way of making filesystem operations transactional - this means that the filesystem can always be opened in a guaranteed consistent state, but has the downside of dramatically increasing the number of write operations to the underlying medium. On a traditional storage device such as a hard disk, this doesn't matter - but on a flash device, this can cause it to wear out a lot faster, especially if it has a poor wear-leveling implementation.

Yes, it will be soon - for now, just using it mostly WiFi, which is great on my 802.11n network.

Hows the text quality when surfing the web? I have played with the iPad and found the text to be a little pixelated (not sure how you spell that :o ). Post some screenshots perhaps
