I have seen this happen on two separate S2x phones. When you're within the Instagram app on android (latest jellybean update), the icons to apply filters to pictures as well as do things such as rotate, etc.. disappear.. If you rotate the phone to landscape or portrait to change perspective, the icons flash for a second and then go away again. You can still select them, just have to try to remember where/what each one is.. Anyone else experiencing this or have any ideas on how to resolve it? Complete uninstall/reinstall doesn't help at all. Thanks in advance for any assistance. I can try to get a screenshot off of my wifes phone if that helps. I had the same issue on my phone but have since upgraded to an S4 which works fine.
