The other day, my launcher kept restarting every time I pressed the home button. So I checked the running services and very few things were running. When I looked at the memory bar at the bottom however, it said 57mb used/1mb free. This device has 512mb of RAM supposedly, so something is obviously wrong here.
Since then, I have been checking the RAM usage bar in running services more often, and adding the used and free values together. From this I've noticed that the amount of total RAM varies wildly, I've seen values between 220 and 350. My RAM seems to just disappear and reappear randomly.
Does anyone have any ideas what could cause this to happen?
