I have been runnung Plutonium for a long time, and Neodium from time to time. I have not seen the big difference in speed that some have noticed. I find both versions speedy and efficient.
Earlier this week, I decided to give S2U2 a try and installed the latest version. BIG mistake! The phone became laggy for the first time and it even crashed. Needless to say, it's gone now and all is well.
That made me wonder how many of my fellow VINdows enthusiasts have experienced the same. Perhaps Plutonium would run smoother for some willing to let go of the offending program .... or perhaps it's an isolated incident?
just sayin'.
