Hi guys, I LOVE to install different apps, try them, compare them, and then pick those that i like (Geek. ok). The problem is that i'm afraid that many installations and un-installations will make the OS very slow (not to mention that i also want to experiment with installing different ROMs and MODs). In windows I use a sandbox software and virtual machines to experiment with new apps. Is there a way to do that on android? is there a sandbox or a 'safe' environment to try many apps without affecting the OS, its files/drivers and the fragmentation of the drive? Thanks in advance!
