I agree with everybody--this is one of the worst androids ever. I got it for $50 from VM because I'm old, broke and cheap. I needed a new phone. If this ROM is any indication, Samsung needs some software engineers. I have never experienced anything so bloated, slow and unresponsive.
I finally got it rooted and flashed the Mirage kernel, but still experience *constant* reboots and CTDs. And memory notices... I partitioned and installed Link2SD and now that problem is somewhat better. But I'm going to have to install a Rom that is more sleek to stop the reboots. Every time I push the power button to get to the home screen, I get a black screen--SAMSUNG, and the bootloop begins. I have to either pull the battery (which, unbelievably, does not always work), or boot to CWM and then reboot again from there.
I sent Samsung a particularly venomous email, explaining that unless I could successfully root and install another OS, I would be sending the phone to them to cherish as a keepsake. What turds....
