Google's Pixel smartphone is one if not the best Android smartphone on the market. It regularly gets updates and Google is really trying to keep it as a top choice for Android smartphone users. One of the new things that Google has released for its smartphone series is a new emergency dialer.

Once the service is enabled on the device you can swipe up and tap Emergency call without unlocking your phone or you can press and hold the power button for five seconds and tap Emergency.

If you have a Pixel smartphone go to the Google support page and follow instructions on how to enable this service. It costs nothing and it could potentially even save your life.

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.

• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 3 – Try to update or reinstall the display adapters

You might also want to update the drivers for Display adapters and Monitors or you might also have to update or reinstall your NVIDIA driver if you’re using one. To update or reinstall the display adapters, follow these steps:

• Tap the Win + R keys to open the Run dialog box and then type in MSC and tap Enter or click OK to open the Device Manager.
• Expand the section for Display Adapters.
• And then select the Display Driver and right-click on it.
• From the drop-down menu, select the Update Driver option and follow the on-screen instructions to install the latest version of the Display Driver.
• Restart your PC after the installation.

If you find that updating the drivers does not help, you can try to reinstall them. How? Simply follow the steps below.

• Tap the Win + X keys and select the Device Manager.
• After that, look for the affected driver in the Device Manager window. And if you see a yellow exclamation mark beside it, right-click on it and select the option “Rollback” to roll back the driver.

When we are working on our computer, we have tendencies to make it look and behave to our best needs and however, best suits us. The Internet has crawled into our lives and made itself a must-have in modern society, internet browsers as a crucial piece of software for viewing the web have also grown and made themselves to be more open for user settings and personalization, Chrome, one of the most popular browser has the option to open a specific set of pages one it is opened and that is what we will cover today in this tutorial. No matter would you like to by default open some online store, maybe an email or news website, you can open each of them or all of them once Chrome is run, making your daily routine more enjoyable and stress-free. The first thing, of course, is to start Chrome itself, once Chrome is up, click on three dots in the upper right corner of the Chrome window and select settings. When you are in settings, on the left side move toward the bottom until you run into a tab that says On Startup and click on it. On right, a new section will open, click on Open a specific page or set of pages. You will be presented with the option to add a new page by typing its URL or getting it from bookmarks or using a specific opened one. You can repeat this process until you have added all pages that you wish to be automatically opened once Chrome is opened for the first time.

BONUS:

If you have noticed right above the setting that we have used for opening a specific set of pages there is the option Continue where you left off, this option will open each page exactly where it was when Chrome was shut down letting you keep viewing where you have left off. This is useful if by any chance your battery ran out or you had to quickly turn the computer off for whatever reason.
