Lately my Tmobile SGH-T989 becomes sluggish at times, it freezes from a couple of seconds to several (10 secs or more) if I wait I can keep using the phone normally after that, sometimes I had several apps running when this happen, maybe that's the reason? The Tmobile phone includes a widget that shows the amount of RAM being used by the phone, with no apps running on the foreground it shows 590/768 of RAM being used. When I press "Clear Memory" "14 apps closed" appears for a second and the RAM goes down to 540/768 but slowly climbs up again. I went to 'Settings, Applications, Running' and I have about 30 apps running in the background, some like "swipe" I think is the keyboard and its ok, but there's others like: Slacker, Social Hub, T-Mobile video chat, etc. So what is a "normal" amount of RAM when no apps are open in the foreground and what app you guys recommend to keep some of the apps from running in the background since these I would think are using some of the RAM also. Any suggestions are welcome, thanks.
