Having problems with your Android getting slower as time goes by? Do you experience rugged motion, frequent lags and hearing your Android device crying out for enough memory? Do you frequently use Task Killer that sometimes make your app become corrupted? If your answer is yes, maybe you need to try this android ram optimization script. This script is ready to put some speed to your device, thanks to Juwe11 of xda-developers.

He had finally completed the long days of testing his script that will solve your Android problem. Juwe11 pointed out in his post that Android works with memory much differently from other OS so having a lot of free memory is not good. That is why he is trying to create the best balance between free memory, multitask, speed when launching apps and internal system speed.

The trick is that having enough free memory that your Android device currently needs. He also confirms that the script does not kill the app automatically when minimized. To run this script, you have to make sure that your Kernel supports init.d and that you have rooted your device. Basically what the script does is to write optimized values to different system files.

To install the script, you have 3 methods listed below:

METHOD #1

1) Make file and add this code to it, if you make this script on Windows, set EOL to UNIX, then save file and name it for example “S97ramscript”, if you have in your init.d other file with “S97″ in name so use “S98″ or “S96″, etc., the name of file must be without extension

2) Then put your file to /system/etc/init.d with Root Explorer and set perm to 777 (rwxrwxrwx), if you have in your init.d other script for RAM management for example Darky’s rambooster, so delete it

3) Reboot your phone

METHOD #2

1) Download attached file (Juwe_RAM_Script.zip) unzip it and put it to /system/etc/init.d with Root Explorer and set perm to 777 (rwxrwxrwx), if you have in your init.d other script for RAM management for example Darky’s rambooster, so delete it

2) Reboot your phone

METHOD #3
