o apps2sd + dalvik2sd
o custom kernel (recompiled, ...)What is a Custom ROM?
Custom ROM is a modification of the manufacturer's ROM or ROM compiled from Android sources. "Change/s" ranges from adding/removing default applications up to including kernels, cpu over/under-clocking, enable/disable features (ROOT, HW acceleration, ...), themes (frameworks, color, ...), keyboards and many other features.
A Custom ROM is usually distributed as a signed ZIP package that includes an installation script for custom recovery. This ZIP is flashed via custom recovery tool.Is it safe to install a custom ROM?
Yes, it is. If you are not satisfied, you can just restore your old ROM using a NAND backup. And yes, you can also use backup tools like Astro or Titanium Backup to backup your apps and restore these in your new ROM (NOTE: In this case it's strongly recommended that both ROM should have same or very similar source/base ROM).What do I need to install one?
1) Rooted phone
2) Installed custom recovery
3) Signed .ZIP file of ROM compatible with recovery
#) RECOMMENDED: NAND backup of your actual ROMWhat does custom ROM bring
Custom ROM brings almost every feature you can imagine.
ex:
OS optimization for games, long battery life, calling, texting, playing videos,...
awesome look - changed icons, colors, animations, wallpapers, menu, ....
reconstructed framework - restart button, reorganized menu, shorts, gestures, etc
allow tweaking - overclok/underclok your device, ROOT, ....
It's really not possible describe here every possibility what you can do/get with custom ROM.what is ...
png-optimized -
png files takes less memory, are loads fasterJIT -
just-in-time compilation also known as dynamic translation, is a method to improve the runtime performance of computer programs, but it takes some time to convert into it on start.HW:acceleration -
using of HW acceleration for rendering GUI. Increases battery consumption.VM.Heap Size -
maximum memory an application can consumestagefright -
In Android 2.2 new media framework that supports local file playback and HTTP progressive streaming
