Samsung’s latest flagship Smartphone duo Galaxy S6 (G920I) and Galaxy S6 Edge (G925I) Indian variants are now started receiving the Android 5.1.1 Lollipop update. The update sent out in batches through Over-the-air (OTA), so it might take few days to become available all the devices out there.
The update brings ability to Sorting apps alphabetically, ability to remove the Quick Connect as well as S Finder shortcuts from the notification bar, exposure control and support for RAW image capture, bug fixes, performance improvement and more. But the RAW image capturing isn’t supported on the native camera app now, so user will need to download a 3rd party app from Play store that supports RAW image capture, like- Camera FV-5.
When the latest update will be available for your device, the Software update notification should automatically pop-up on your notification bar; you can also try to check it manually by heading to Settings -> About Device -> Software Update.
