Problem #2 – Device stuck on Do Not Disturb mode

A temporary workaround that has worked for some is using an third-party app, such as Rotation Control, that will let you manually trigger the switch to the landscape orientations. This seems to be a software issue and is something that Google is tracking, so a permanent fix will hopefully be available soon.

If this is proves to be a hardware issue, the only option will be to pick up a replacement.

This could also be an issue with the accelerometer and G-sensor as well. Download an app from the Google Play Store like GPS & Status Toolbox and re-calibrate the sensors, and see if that fixes it.

Uninstall any apps that were added just before the problem started, and see if that fixes it. If it doesn’t, a recently-installed application is the cause for concern.

To check if this is the case, boot the device in Safe Mode (you can find the instructions below), and see if the problem persists. A rogue app may be causing this issue.
