How to set Details page to be default view in Lightning

In Lightning Experience, when we open a record, in the Tabs section, We would like to change the default tab that is visible when the record is opened. For example: Related, Activity, Details, Tasks, View. It currently shows “Related” and I would like to change this to Details page.

We can change the default Tab that is viewable when a record is opened for any Object in Lightning Experience, follow the below steps:

Step-1: Open the App via app launcher and Select the Object and Open any record in that Object.

Step-2: Once Select the record in the object ,Open that record of that Object.

Step-3: Click on the Setup button at the top right corner of the page and click Edit page. 

It should take to the Lightning Edit page (Lightning page builder).

Step-4: Click on Related or Details Tab.

Step-5: On the right side column we can see a way to make “Activity” as default tab.

Step-6: Change the value of Default Tab as “Details“

Click to Save.

Step-7: Now, Click the Activate Option.

Now we can see the details as default when we open the record.
