Decent, but oddly buggy

I've only had a couple cell phones, and don't really consider myself a connoisseur, nor do I go for high-capability cell phones (I bring my laptop everywhere).
This one, though, has already rather dramatically let me down, in a couple ways.

First: It has, without exception, crashed every single day. Several times, usually.
I've had it for about two weeks, the fact that it's crashed this often does not bode well for the future. "Crash" being defined as a random reboot. If I'm going through menus, updating contacts, checking my bluetooth status, or even dialing for a new phone call, it'll suddenly reboot. The more I click buttons, the more it crashes, though it seems to happen only on the menu-like buttons (never number keys, thus far). It especially happens when I'm trying to be quick about my clicking, and click "OK" for screens that haven't yet appeared. More on that later, though.

Second: sending vCards to my phone through bluetooth is very... shall we say, "questionable".
It seems Samsung just does not know how to implement bluetooth very well. Though the bluetooth communication icon will appear, and it'll flag my computer as being connected, it simply will not actually do anything with bluetooth unless I initiate the file transfer while viewing the bluetooth menu screen. The entire process will simply sit and do nothing for several minutes, until my computer decides it's timed out, and cancels it itself.

Third: everything. is. slow.
My comparatively-ancient ex-phone allowed me to click through menus at high speed, though granted, I had very little to actually go through. Most of my friends older, newer, more expensive and/or cheaper cell phones move through menus transparently instantaneously.
This one? Nope. The default theme has visual glitches while changing menus or selecting menu items (it uses a blue highlight to show the current choice, but doesn't move it smoothly and randomly drags the previous / next menu choice text along with it in the transition in a very broken manner (either it's a glitch, or the designer / QA team is/are blind)). Even going to the only other, non-animated menu theme (garish greenish colors and red contact pages... ick) only sped it up slightly, and there's still a perceptible (and functional) lag between clicking a button and the screen updating.

Fourth: as far as I can tell, the outside mini-screen is useless.
There's no way to keep it always on, as far as I can tell.
It turns off after about 1 minute.
It does not turn on unless the hold-key status changes, which takes a couple seconds of holding the hold button to apply, or the clamshell is opened. To the best of my knowledge, there is no way to get it to display what the camera sees.  It's blank the whole time the clamshell is open, no matter what settings I toggle.
I would use it as a clock, but it doesn't show anything when I look at it. Its external existence is entirely useless until the clamshell is opened-and-closed. The entire point of using a phone as a clock is slowed down, when it could be nearly instant. All they would have to do is to have an option to keep it on, or have it "wake up" from any button press. But it does neither.
WTF?
It should be functional for the music controls, but I don't have that use for it, and it should have more than one use.


On the plus side, it does one thing my previous phone didn't. It can send & receive all of my contacts in one operation, instead of sending a maximum of 10, and receiving a maximum of 1.
It also exists. I've lost my previous phone. Existence is usually a positive thing.


EDIT: further notes after having for a while:
It's crashing a bit less often, though the frequency that it forgets that I had locked the keys (even when sitting on my desk overnight) implies that it is still happening.
Locking the keys: Why do I even do it?  All it affords me is a few seconds where the media buttons on the outside don't respond.  All the side buttons respond whether it's locked or not, in exactly the same way.  That's not a lock button, that's a "feel-good" button that doesn't make me feel good, because I can't trust it.
Best features: hit a key or two and press up to search contacts (272 => brings up Brad and Brannon contacts).Technically, this should work with the menu when you press down, but it only works after about 1/10 crashes.  Not reboots, as rebooting does not make it work, only the occasional, lucky crashes.
