Very regualrly, if I attempt to type in a web address into the address bar on the S7+ using the OEM keyboard, the first letter I type makes the cursor jump to the beginning of the line and start the second letter at the beginning. So, if typing google, as soon as I type the g I end up with oogleg. Hitting the arrow key won't let me to the right to delete the end g. If I click on the address bar to edit, the whole address typed disappears.
This happened on my S4 keyboard also. I'm beginning to question why I bought another.
