Okay, please be gentle as I am new to posting but not new to reading the forums. I've seen a lot of postings saying MightyRom has the lowest RAM usage out of the custom Roms. However, I was wondering if it lower than the standard vzw rom? I find it extremely annoying to always be running at 73% usage with the vzw rom. Any feedback would be much appreciated!
