Some of the coolest features of Pixel 3 are software related. This means that you can get many of them on non-pixel devices. "Flip to Shhh" is a perfect example of this. This allows you to quickly hibernate your phone by placing it face down. This can be replicated to other Android phones using a simple app.
Imagine that you are in a meeting. Instead of having to go into your settings to enable DND mode, you can simply put your phone face down on the table. Done. You will no longer be distracted from your phone. If you need to rest for a moment, do not fumble with your phone, but place it face down to get a distraction-free zone.
First, download the Flip DND app, which is the best app we've found to mimic Pixel 3's Flip to Shhh feature. It's free and is developed by the same team behind popular apps like Sleep as Android and Twilight:
Step 2: Give Flip DND the Right Permissions  Start the app now. You will be greeted with a Permission Request dialog. This dialog prompts you to allow DND Flip to access DND mode. Click the "OK" button to continue. You will be redirected to the Do Not Disturb screen, which will display a list of apps. Find the "Flip" app and give it access by toggling the switch.
When you press the toggle, a new dialog box opens asking if you want to give the Flip DND app access to your Do Not Disturb permission. If you click Allow, the app is granted the permission.
If you have a Huawei, OnePlus, Nokia, Xiomi, Meizu, Asus, Samsung, Lenovo, Oppo, or Sony device, the software on your phone may automatically exit the Flip DND Service after a while. This may cause the Invert To Shhh feature to stop working. If you need help, make sure that the Flip DND app on your phone is excluded from the battery optimization feature.
Step 3: Customize Your Experience (Optional).
Possibly take some time to change the app's settings. To do this, press three dots in the upper right corner of the screen.
By default, the app has the Vibrate setting enabled. When enabled, the phone vibrates twice when you place it face down on a surface to indicate that it is now in hibernation. When you turn your phone off or on, it vibrates once to indicate that it is no longer in DND.
When the Sound option is on, you hear a "Pssst" when you place your phone face down. "Priority DND" lets calls and messages ring from highlighted contacts while your phone is turned over.
You can manually switch the DND mode by tapping the pink button in the lower right corner of the main menu of the app. This is not necessary. It's just a nice extra feature in the app.
When the app is set up, it also displays a running alert that indicates that the app is active. If you click the "Hide notification" button, you will be taken to the notification screen for Android system apps. Here you can block notifications for the app by clicking the "Block" button. Note, however, that this may cause the app to be shut down by the Android storage management system, which blocks the main features.
Fallen, there's nothing left to do. Flip DND automatically launches each time the phone reboots, and the service always runs unless you click the Stop button on the app's main menu or in the notification. In other words, you can forget that you have even installed the app now.
From now on, simply place your phone face down on a surface and DND mode will be activated. When DND is enabled, you will not receive any audible notification or vibration when someone sends you a text or calls you.
It should be noted that certain phones may have problems with this app if they do not have a gyroscope, accelerometer, magnetometer, or proximity sensor, as these sensors are used to detect when the phone is hidden. In addition, apps that are not in DND system-wide mode on your phone can continue to post notifications. However, for the vast majority of devices and apps, this app is perfect for replicating the pixel's "flip to shhh" feature.
