Ok so since the 4.3 every now and then when i try to answer the phone the swipe button is not working i can see the thing moving it see my finger getting dragged to the edge of the answer circle but when it touches the circle is like it never dose it just like i would lift up my finger and sometimes even more funny it actually answers the phone but the screen still shows me i still need to answer after a few seconds of this the call is interrupted like the phone things i did not answer and this is getting really annoying, it happen today about 3 or 4 times out of 15 calls or so.
