I have a Samsung Galaxy S (AT&T Captivate) that is rooted. I have various ways to tweak the amount of free RAM the OS leaves on the phone. The default is 48 MB, but I was wondering if I could actually go lower without impacting phone performance. Are there guidelines posted anywhere, or that can be deduced based on knowledge of the Android platform? Or should I trust that the default settings are appropriate? I understand that when it comes to free RAM, more isn't necessarily better, but I understand that there is still a threshold that I don't want to dip below.
I'm running a 2.3.6 Gingerbread based ROM. For what it's worth, I'm running the Zeam launcher.
