I have just updated my Samsung S7 device to Android Version 7.0, Security Patch Level Feb 1 2017. But unfortunately the user experience sucks despite my expectation. New Address Book has a very bad user experience. I have to double tap to go to a contact detail. It was one tap on the older version. If my contact has two different numbers it is too hard to choose to ring the number which i decided to. I have to drill down to find the other number! On the older version i do only one tap then it goes to contact details then i choose one of the numbers. But at the new versin i tap on a contact then i click on "detail" button then it goes to contact details! It is not a good user experience!!
