What is a Google Pixel smartphone?
The stock Android interface
Google develops the Android operating system and the Google Pixel smartphones. As a result, they work well together. A Pixel smartphone runs on a basic version of Android, which is called stock Android or Pixel UI. That's a clean version of Android with a simple interface that's easy to use.
Software and updates
Because Google develops the operating system by themselves, you receive software and security updates the minute they come out. Many manufacturers adjust Android with, for example, pre-installed apps, a different design, or special functions. As a result, it takes a lot of time and money to adjust (security) updates. This isn't the case with Google Pixel, so you'll receive security updates every month for 3 years. You'll also receive 3 updates to a new Android version. With other brands, these are usually no more than 2.
Little 'bloatware'
Other smartphone manufacturers often install their own apps before you receive it. Think about the Bixby assistent by Samsung. You don't have this with Google Pixel smartphones. They don't have many unnecessary apps preinstalled by Google. You only have the usual apps, like the Play Store and Google Maps. That way, there's a lot of room for your own apps and files on the storage.
