Hi Scott, You've been a GREAT help, as have the others! I'm back to working with the original libmtp, with VLC working just fine (but I'm not sure how to test rhythmbox as I've never used it). I'm confused how to explain the idealized setup since it took a few reboots and gyrations to get it to work again for me once I reinstalled the original Centos libmtp, and especially because we (apparently) have to plug the phone in to see the MTP/PTP setup screen, and once we do that, we again have to reboot, so, this sequence below is idealized as I went through a bunch of reboots in the process, and I forgot to unlock the phone a couple of times also. With that caution as the caveat, I "think" the simplest procedure for connecting by wire on Centos 6 is the following: 0. DO THIS ONCE! Connect the Samsung Galaxy S3 Android 4.0.4 phone by USB cable to your Centos 6 PC in order to put the phone permanently into PTP mode (as explained earlier) and then (I think) you MUST disconnect the phone and reboot the Centos PC! 1. With Centos booted, no phone connected, and the phone already in PTP mode, make sure the phone is unlocked! <== very important step! 2. With the phone unlocked, connect it by USB cable to the Centos PC. 3. The phone will beep, and your "Places" menu should have "SAMSUNG_Android_SGH-T999" and your file browser should open up to location "gphoto2://[usb:003,003]/". Voila! At this point, you can copy and paste picture and screenshot files from your phone to your Centos PC! I just tested that sequence, and, as long as both the phone is unlocked at the time of connection, and a reboot (or two) occur after the libmtp was put back to the original, it works as desired (for me). Since a user new to this thread won't have touched their libmtp, they won't have to do all the reboots that I did. Note: It seems to me there should be no need to install the new libmtp (since we're using PTP instead); hence vlc and rhythmbox should be unharmed; however, this sequence worked with both the old libmtp and the new libmtp; but, of course, neither rhythmbox nor vlc worked with the new libmtp, so, that's why I re-installed the old libmtp (and this won't work unless you reboot after messing with the libmtp - for reasons wholly unknown to me). Whew! Sorry for all the confusion. Things are only simple when they make sense. Thanks for all your kind support, patience, and help! I'm amazed at both how hard it is to figure out this workaround ... yet - how easy the workaround is - once you know to both keep the phone in PTP mode and to ensure it is "alive" when connected. Note: The "real" solution is to get MTP to work, which is the point of Ljubomir Ljubojevic's post earlier today.
