Hi all, I am just new to the Galaxy 551 which I got from Bell as an upgraded hardware. This thing is completely different from my old phone which is already 7 years old. I wish to find out: 1) How do I know whether an optional SD card was installed on my phone?? I cannot find any SD card slot on the side of the phone but I was told that there is one installed. 2) How do I find out whether the pictures/video are stored in the phone's memory or the SD card (if one is installed) ?? 3) If I take any pictures/video with my phone, how do I find them & review them on my phone? Thanks for your patience!!
