So the 4.3 Firmware for the International S4 came out today. With android 4.3 google implemented FSTRIM support for eMMC flash storage.

Users are reporting "snappier" performance especially in the launcher. So I put together this FSTRIM package which is flashable in a custom recovery.

Basically this is what it does https://play.google.com/store/apps/details?id=com.grilledmonkey.lagfix&hl=en

BUT this app is semi-defunct and was made for nexus devices/htc devices primarily (used it alot on my old phones).

What it does:

1. FSTRIM's your /system partition upon flashing.
2. Flashes an int.d script and the FSTRIM module (someone compiled this module for me a while ago, so credit goes to them) to your device and runs it on each boot.
3. Makes your device "snappier".

This is not needed on a 4.3 based FW and YMMV.

Tnx for this. This has really solve the occasional lag on my gs4. I have tons of app in my phone and this trim down memory usage. This is more noticeable when using browser, app drawer and app manager. Tnx. I tried everything and this was the only one that works. ;)

Any way to see if this actually loaded? Pardon the ignorance, but I can't seem to find what init.d scripts are loading.

A simple way to know is to look at your ram usage with some app. I used temp cpu v2 widget which shows cpu, ram, temp & battery usage. Before applying this mod I could easily see my ram down to 200 and below with tons of apps I have and would experienced lag in app drawer, browser and app manager. but now it is up to 600 and above and no lags what so ever even with multi tasking.
