|Knowledge Article Number||000198647|
Salesforce1 for Android version 5.3 added a new section called "Call History" which is accessible within the left-hand navigation screen. It will show your recent calls made on the device and assist with logging those calls or creating contacts.
You can disable this feature for all Android devices using Salesforce1 in your organization by adding a custom attribute to the Connected App section.
