Question about Android

[rado84]

Where Android RAM is concerned, I think it's just wise to reboot the phone frequently... that solves most RAM problems for me; ie I tend leave my phone on and charging for weeks at a times, and it degrades performance, but when I reboot I get that performance back. And I think that's because the nature of Android apps in the sense that once they have been opened, they don't really close, they just going into the background... but still occupying RAM. I used to think that they were eventually closed in that situation... after laying dormant for a certain time... but I'm starting to doubt that now... so I think rebooting is perhaps the only way to truly remove them from memory. But that's just my opinion, and it could be wrong.

Android apps are closed when you drag their title bar down to the bottom of the screen. If you just tap the X button, they go into background.
That's how it works on my best friend's phone.
