If you're using a Samsung Galaxy Note 4 on Verizon, you may want to check for an update. The carrier has just begun pushing out an over-the-air update to the phone, bringing it up to date with the June Android security patch.
The current software update gives you the most up to date Android™ security patch on your device.
Once updated, your Note 4 should be up to software version MMB29M.N910VVRU2CPF3 with the latest security patch installed. If you haven't yet been prompted to install the update, you can check manually through you phone's Settings menu.
Have you nabbed the update yet? Let us know what you think in the comments or on our forums!
