Re: i can't find my pictures on my android 4
Welcome to Android Central! How were you transferring the files? Did you use the Copy command or the Move command? If you used Move, and if something went wrong with the transfer, then the originals may have been deleted already (which is why Copy is always safer--when you're sure the transfer was successful, go back and delete the originals yourself).
Go to Settings>Storage, Unmount the card, remove it, and insert it into your computer. Use Windows Explorer to look at the card and see if the photos are there.
