How to add google search in home screen?

This is quite straightforward. On most Android phones, it is very easy. Simply long-press an empty space on your home screen. Then, tap on the 'Widgets' option that appears. You will need to scroll and find the Google app section. From there, just select the search bar and drag it to your desired spot.

For an iPhone, the method is also simple. Press and hold your home screen until the apps jiggle. Tap the plus (+) icon, which is usually at the top. Search for the Google widget, choose the search bar style, and add it. This gives you instant access to search without opening any app. Hope this helps
