Why I returned my V20 for an S7e

I traded in a device for the LG V20 and took advantage of the $200 trade in credit At&t is offering. After 4 days with the V20 I am in the process of return it. The main reasons are battery life, lag and at times an unresponsive screen particularly when the phone is laying on a flat surface such as a table. I'll be trying out the iPhone 7 Plus, I am not particular when it comes to today's device software.
No phone will be a winner for everyone. I hope the iPhone will be a winner for you.
