I fear now that I'm gonna have to return it because of one major design flaw. That is, the use of the EXT filesystem.
When I try and copy a selection of folders full of photos to the Nexus 7 whether via USB MTP or Wireless, every single file has had it's timestamp changed to the exact time/date the copy operation occurred. This for me, is a complete nightmare.
I have loads of folders with photos that I need to keep in chronological order, if the timestamp is changed (without actually modification of the files) I am unable to sort them date descending (so the newest files appear first).
I have even tried copying a test selection to my Dropbox and using FolderSync to sync the photos back down to the device - however, this doesn't work either. As soon as the files are on the device the filesystem modifies the timestamp.
I could of course just leave the photos in the Cloud and view them that way, which I don't mind but I have yet to find a photo gallery app that is able to view photos via Dropbox and provide slideshow capability without downloading them to the device.
Everything works just fine on my SGSII (running ICS 4.0.4) when copying data as all timestamps are retained. I believe this to be down the use of the FAT32 filesystem as opposed to EXT and the fact that USB Mass Storage works and not crappy USB MTP as used on the Nexus 7.
If anyone has a successful workaround to retain timestamps of files I would appreciate it. I can't believe its so difficult to copy a few photos to the device.
I don't want to send it back as I love the Nexus 7 and Android in general but I think I'm gonna have to if I can't get it to work the way it should.
