OxygenOS 4.0.1 rolls out

OnePlus promised to deliver Android 7.0 Nougat to the OnePlus 3 and OnePlus 3T handsets by the end of 2016, but slightly missed this self-imposed deadline. OxygenOS 4.0 arrived last week as the first Nougat-based firmware for these two flagship devices. Now, a small update comes to fix some issues that were probably missed while rushing to release last week's big update in time.

Probably most users are still using a Marshmallow-based OxygenOS build since OnePlus added the new Nougat features to the list of improvements for the latest update as well. These are the highlights:

Upgraded to Android 7.0 Nougat

• New Notifications Design
• New Settings Menu Design
• Multi-Window View
• Notification Direct Reply
• Custom DPI Support

Added Status Bar Icon Options

Improved Shelf Customization

Updated APN Settings for select Carriers

Fixed Proximity Sensor bug during calls

Increased System Stability

Unfortunately, it looks like the new firmware still has some problems. According to the official OnePlus Forums posts about this update, downloading apps from the Google Play store might not work, WiFi connectivity could be unstable, while APN might cause mobile data issues. However, when trying to download via Data Roaming and failing, users encounter a known Google issue and not one bug added by OnePlus to the software.

As usual, this is an incremental update that rolls out in stages. Since it still has some problems, we will probably see at least a new version coming out by the end of the month. Those who want to grab it now and did not receive the automatic notification yet should go to Settings > About phone > Software updates to check manually.
