Went to Verizon and played around with the Maxx HD, including camera. While I wasn't blown away by the camera but I thought it was decent enough. It definitely takes better pictures than my D2G. I tried to find some low light shots (hard to do in the store) but got some that I thought were acceptable. Of course they were kind of underexposed and noisy but so were the same shots with the Galaxy S3. The S3 might have had a slight edge by having a bit less noise but with the phones tethered to the counter about 8 feet apart I could not get exact side by side shots. I got the reassurance I was looking for in that I know I can live with the camera in the Maxx HD. I think I'm going to love burst shot mode!
Other items: The Maxx HD was showing signal strength of -62 dB on 4G whereas the Galaxy S3 was -72 dB. BTW, I also looked at the Razr M and it had signal strength of -68 dB, also beating the S3. The Maxx HD had an incredible 62 MB/sec download rate on SpeedTest; the S3 had 43 MB/sec download tests. I asked S-Voice on the S3 a couple of questions which it couldn't answer, "Where do I find the network signal strength meter on the Galaxy S3?" and it had to refer me to the internet. After playing with the Maxx and the S3 I messed around with the iphone5. Honestly, after looking at the screens on the Android phones, the iPhone5 looks like a toy. It does have a beautiful looking screen and I love the way it responds to finger swipes, but really, it's a dinky little phone. I couldn't find Siri on it!
I can say I'm no longer on the fence--it's Maxx HD over S3.
