If you have problems with your Samsung Galaxy S (all versions) after you updated from 2.1 eclair to 2.2 froyo, you’re not alone. Turns out that there’s a problem with Samsung and their Galaxy S’s, and many people are experiencing lag, or general slow-ness, when using their phones.
Android 2.1 was pretty okay for me, but after I updated to Android 2.2, things got horribly slow. Mail and messages would take ages to load, and apps would take forever to run. It got to the point where I was about to switch phones. Fortunately, I found a solution online. If you’re facing the same problems and have not tried this solution, I highly encourage you to give it a shot.
If you’re not sure if your Galaxy S is slow, go to the Market and grab Quadrant. Run the tests, and if you’re not getting somewhere around 1800, your phone is slow. When I ran Quadrant initially, my Galaxy S only clocked in at around 800-900. After this fix, it’s doing 1800-1900.
Step 1: Z4Root
Download Z4Root. This app allows you a one-click method to root your phone, which is kind of like jailbreaking for iPhones. With rooted phones, you can grant superuser access to apps, which allows these apps to do things that they normally couldn’t be able to because of permission restrictions.
Problem is, Google pulled Z4Root from the Market, so you’ll need to visit the Z4Root page on XDA Developers forum, and manually grab the file there. Some people may face a problem with obtaining a file from that forum, so I’m going to host it as well. You can download it here: z4root.1.3.0.apk
Once you get the file, either use Dropbox, or transfer the file to your phone via USB. Next, run the app “My Files” (should be a default Samsung app) and run that .apk file that you’ve just transferred to your phone.
Important: Do not apply the temporary root option because it has a high chance of bricking your phone.
Step 2: OCLF
Go to Market, and download OCLF. It’s free, but donate to the developer if you can, because this app will save you so much frustration. After it’s downloaded, run it, and wait for all the checks to complete. Then install the EXT2 tools. After that’s done, you should see a message saying that it’s successful, so press back to go back to the menu, and wait for the checks to complete again. You should now see that the option to install the “One click lag fix” is enabled, so choose that. It’ll take a while to set up and your phone will reboot automatically, but once it’s done, you should have a much faster Galaxy S.
