So....after 40 minutes on hold for Tier 3 support, I finally spoke with someone. I told him exactly what the issue is, how I moved from a BBerry to this phone and had good data reception on that phone, but not on this. I also let him know that I've spent 6+ hours on the phone with Sprint tech support and we have re-set everything and it didn't help. AND, I told him how I even took the phone into the Sprint store, where they noticed the same data issue with their display phone, but not with the BBerry or the Motorola Photon phones.
He IS Tier 3 - highest level of tech support one can go - and he said their team has NEVER heard of this issue until my call.

He said he can troubleshoot the phone, but not the network (Sprint). I told him that the issue is not with the network (hello, other phones listed above are getting fine data reception). And, I added that I have friends all over the country (NY, Boston, Florida) who have the same phone and have the SAME EXACT issue with data connection, and have been through the same troubleshooting steps with no change in data connection status (particularly indoors).
He said he doesn't know what to tell me, except perhaps the phone doesn't get reception in MY area (um, didn't I just tell him the same is happening to friends in other states?). He suggested I perhaps have a "bad" phone and to exchange it. I said a few friends HAD done that and it didn't help. I told him there are people all over Android Central and Sprint community forums from all over the
country complaining of the same issue...and he said, "I don't know what to tell you...this is the first we at Samsung have heard of it". I said Sprint reps on the community forums had said Samsung was aware of this and was working on a "fix" and he said he can't speak to what Sprint reps are saying (in other words, he can't say Sprint is outright lying), but that he was at the highest level of tech support and no one had heard of/or was working on a "fix" for this issue.
Well...then I became snippy (because I'm annoyed with their lack of "support"). I said, "So basically, you're Tier 3...and I've been on hold for 40 minutes while at work, only so you can tell me...you don't know what to tell me?" I'm not proud of getting snippy, but this is so annoying that neither Samsung NOR Sprint want to take responsibility for their part in a REAL issue.
He said he can certainly write a report about this and forward it to their product analysts, but as far as personally being able to help me...he couldn't, because this is the first he'd heard of it and Samsung was not aware of this being an issue with other consumers.


Seriously?? And Samsung wants to beat Apple with a product like that? (I know, Apple has its own issues)
So I said...I have asked my friends (and people on this forum) to call Samsung tech support and complain about the same thing, so if he hadn't heard of this issue until ME, he will after me..and what will Samsung do then? He said, "I don't know". Great. But he did say it would be a good idea if other people call...so they have as much info as they can on this. It's a case of being the squeaky wheel, I guess.
I suggest everyone call, please. Don't let my experience above discourage you from calling...Samsung needs to HEAR this is a REAL issue so they will have to put out a fix.
This type of irresponsible behavior should not be accepted by consumers. If Samsung can't figure it out or even look into a serious issue such as this...then they deserve to have everyone return their phone.
End of rant. Everyone...
CALL!
