Essential Phone PH-1 have just started receiving the latest Android Security Patch. The company is doing really a good job by giving the monthly security updates.
Arriving in with build number NMJ51B, the update brings Android Security Patch for the month of December to the device.
Aside from this, the update does bring some bug fixes and improvements but there aren’t any new features.
As usual, its an OTA update will roll out gradually so be patient. Meanwhile, you can head over to the Settings menu of your device to manually check for the update.
Before downloading the update make sure your device is charged up to 50 percent and is connected to a decent internet connection.
