And even if flash custom ROMs I have this lag feeling, and not only feeling sometimes. I will be more accurate.
1) When I install apps or uninstall apps, I have some lags, now OK the phone is doing a big task but it is a bit too laggy.
2) Switching between apps can be laggy some times, and not just with big apps.
3) I have noticed that even having not much apps working background, the phone give me this impression of lagness, I have 1gb ram and a quad core, I get angry if it start to run slowly only for some apps working background, I mean the hardware is powerfully enough.
After all I must say that I have tryed these ROMs.
Carbon, slimbean, liquid smooth, and CyanogenMod (that is a bit better on performance).
My favourite is slimbean because I feel it stable.
And I have tryed most of the kernels, like werewolf, optimous prime, and iodak at last, and I like this last one.
Can someone help me understand this? Thank you guys!
Ah, sorry for my not clear English :S
