i rooted my samsung galaxy i5801 yesterday and started playing around with it. i downloaded an app called droid tweaker. it had an option to change the dpi on my phone saying it would make the screen look higher quality, so, foolishly, i set it to its highest setting. my phone rebooted and when it turned on it was zoomed right in and i couldn't click on very much, and droid tweaker said that i no longer had root access on my phone so i couldn't get back on that to change it back. I've tried everything, even a full factory reset! is there anything i can do????
