Around two weeks back, Samsung rolled out Android Marshmallow update for Galaxy Note 4 in India. And, just four days ago, Samsung rolled out April security patch for Galaxy Note 4. Now, Samsung is rolling out May security patch for the Galaxy Note 4 in India.
The April security patch was 360 MB in size, whereas, the May security patch has a size of 378 MB. Not much has changed from the last security patch, just some bug fixes and performance improvements.
This update is rolling out over-the-air and will eventually reach all the users. If you haven’t received the update yet, you can check for it manually by going to Settings > About device > Check for updates.
