    I would like to ask. I’ve applied this update to my phone but I have a bit of problem. There are images that I’ve taken prior to updating to ICS that are now showing as corrupted. I can see the thumbnails when opening the folders but when I tried opening the images themselves, it becomes just a box with a white icon and thunderbolt. I also can’t transfer them to other folders.

    Kindly advise. Thanks.
