Currently, Android smartphone makers need to include Chrome and Google Search to offer their customers access to the Google Play Store and its library of apps that millions of people use. Without access to the Play Store, an Android smartphone is destined to fail due to a lack of apps, as mobile app developers usually only make apps for Apple's iOS and Google's Android.
After 90 days, Android phones may no longer come with Google Chrome or Google Search should an Android smartphone maker not wish to include them. Instead, smartphone makers can exclusively pre-install their own web browsers and search apps, without needing to include Google's Chrome or Search apps.
This might not affect anyone who usually uses whatever default browser is on their smartphone, like Samsung's Internet app. But anyone who would actively want to use Google Chrome and Google Search on an Android smartphone that doesn't come pre-installed with those apps would need to find them in the Google Play Store and install them manually.
Smartphone makers could still include Chrome and Google Search, but they wouldn't be bound to do so. Many Android smartphone makers already offer their own web browsers as the default browser, but they also include Google's Chrome as an option, often hidden within a smartphone's app library.
Using Chrome has several benefits if you use other Google products and apps, as they can be synchronized together for ease of use and automation. Google also gets more ad revenue from Chrome users.
As for Google Search, Android users wouldn't necessarily have built-in native access to things like Google Assistant artificial intelligence (AI) voice assistant or the Google Search bar that often comes pre-installed on an Android phone's home screen. Google Assistant is currently one of the company's highest priorities, as AI is seen as the next frontier in tech.
Specifically, omitting Google Search would give other voice-activated assistants, such as Samsung's Bixby AI assistant, a higher chance of being used over Google's Assistant.
