To update the Sprint Galaxy Note 4 to Android 5.1.1, users have to go to the “Settings” option on their device and tap the “About phone” option. After that, users need to tap the “software update” option to proceed.
In case any custom recovery like TWRP is installed on the device, users will have to remove it and replace it with the stock recovery to be able to install an over-the-air update.
