I'm using 2.3.6 on my first Android phone. I moved some photos from my PC to the phone (no SD card) and during the copy process I received a message - "may not be compatible with device". I can see them in my gallery but get no response when I try to select one of them for wallpaper.
If I tap it, the photo is isolated and that's it. No response from menu icon. There are forward/backward arrows at bottom of screen and tapping them just gets me the date I copied the photo to the phone.
Thanks for your help.
