Increase Sony Xperia Arc, Arc S Internal Memory Without Losing Performance [ LT15, LT18 ]

How to increase my Sony Xpria Arc LT15 or Sony Xperia Arc S LT18 internal memory? This is a big question for most of the Android user. Now it’s possible. Using a init.d script we can increase the internal memory as we want. It can be 1GB, 2GB or even more. This method requires the root permission, SD card 2nd partition and a custom recovery.

However this method doesn’t increase the RAM. This mod work on android 4.0.4 ICS and android 4.1 jelly bean ROM. If you have class 6 or higher value micro SD card, your performance increase, but if you have class 5 or lower, it makes lag. If you have a lower class micro SD card, its better follow this Link2SD method to increase internal memory. This method developed by the XDA forum “XtremeSilencer“.

If you already use Link2SD, you can’t use both of these method. You have to select either one method.
