I don't use Instagram much since "Facebook" buys it. The new update includes a fix for the front facing camera while using the advanced camera and some additional fixes for the photo filters for certain Galaxy Y and Ace devices.
If you’re still using it as well, head on over to the Google Play Store and check for the latest version, numbered 1.1.1 — the update should already be there waiting for you. If you’ve been living under a rock and haven’t installed it, or you’d like to go back to the app and give it another try.
