from my reviews during a purchase for my son, there were MANY issues with the LG phones, in particular the Neon, with the phone turning off on its own, connections being lost during calls, some issues with the touchscreen dialing, and quite a few related to keys not working after 6 months of use. By keys not working I mean some keys needed to be pushed twice or stopped working reliably.
Many of the LG models seem to share the "auto turn off" feature which might relate to power problems or battery contact issues. I never saw any conclusions drawn on that but it was model wide so could be a manufacturing quality issue.
Yes, I do agree with oblaP that the first generation Neon had alot of problems, just as the first generation Rumor devices had just about all the same problems, but when the Rumor 2 came out, there were alot less problems with the phone, which is why I have more faith in the Neon 2.
LG do make some bad phones every once in a while, but they usually fix the problems when it's a second generation device.
