RE: bionin pics & vids
here are a couple ideas that might help you out:
1)If your computer has an SD slot, have you tried removing the memory card from your phone & seeing if your computer recognizes it? I've had a problem with other Android devices in the past not cooperating with my Windows laptops, and this was generally a good starting point to troubleshoot.
2)Does your PC have a bluetooth connection? It takes forever and a week to transfer anything, but it may work for you to fully transfer the files properly.
3)If this doesn't seem to work, do you have any aftermarket programs such as Winamp, iTunes, Zune, GOM, etc that you could try opening the files in? I've had problems with the stock Windows software, in general, agreeing with the formats that Android uses. Things like WMP, paint, etc are hit or miss sometimes. For videos, I've had much better luck getting my computers to read them when using other programs like VLC, Gom, etc.
The last thing I'd check is the data cable you are using. If it wasn't completely plugged in, or has a bad lead, you may end up with faulty file transfers.
If you're still having problems and you've tried all these, I'd take the phone back to the store, and have them trouble shoot it. I've never had it happen, but I've had friends who took pics and their phone said it saved them, but all their files were corrupted and lost. Good luck.
