Do they make anything better?
Depends. There are a slew of new phones, but some people say it never gets better than the D1.
They'll send you another D1 as long as they have them in stock. Good luck with this new one! Never know, might get a winner this time!
They sent me a refurbished droid1. The speaker on it is busted/buzzing even though I can hear what's going on. Do they even test these phones or just send them? I'm thinking about calling them back to tell them I want something that actually works correctly.
I think they do a visual inspection, replace what's scraped/dented/bubbling/cracked, power it up to make sure it boots, then ship it out.
Send it back. A buzzy speaker like that is reason enough to get a replacement.
