When I got my P7 initially, it was so bad that after a couple of days I threw it in a drawer and went back to my old phone.

Then someone said you have to lick your thumb or rub it on your forehead before you register it. So I did both. And now it works like 95%. The other 5% I have to lick it again to get it working. Don’t ask me why. Yes, it is stupid. Yes the old one on the back is still better, but it’s not terrible anymore…
