I use the task manager widget and every time I check it shows about 50 mb ram left.. This seems quite low considering I barely use any widgets and programs that run in the background besides the stock programs. I don't like using task killer that much as it kills battery and within 5 minutes it's back at 50 mb ram again. The phone does seem to go slower fast.. How can I check which app is using most of the ram? Is there an app to check this? It's a bit anyoing because others say it stays around 100 mb.. wasn't this phone supposed to have 512 mb ram anyway?
