Had my phone since Tuesday night. The only actual problem I've seen:
WiFi issue - it appears to be connected to WiFi traffic is not going anywhere until I disable and re-enable it
Edit - OK - just happened again. This wifi thing is really starting to get annoying to the point where I cannot reliably keep the phone on wifi at home. I have never had a problem with my N1 nor any other wired or wireless devices. I used fing to help see what's going on and the phone is associated to the wifi but is unable to ping/scan anything and likewise, I'm unable to ping the phone from another host. I need to see if it does this at work too. I've not paid enough attention there yet.
Other issues I've seen that I'm not sure are "problems"
- Playing Draw Something, the line sometimes does not keep up with how fast I'm drawing, like if I'm filling something in by scribbling.
- Loading pages in the Reddit app, I sometimes have to reload the page or change from portrait to landscape to get it to display.
- The camera app wouldn't open for me one time - rebooting fixed that
- The auto-brightness does not tone the backlight enough when in a very dark environment - i actually manually set it to the lowest setting.
Edit2 - when playing Pandora, it will play a song fine, then once it gets to the next track it will play a second or two, pause, then skip to the next track, play that one out then repeat at the end of that one
Other than that, I love the phone. Worlds better than my Nexus One.
