have had this phone 6 months. Since about 2 weeks ago, I have not been able to answer incoming calls. I touch the green phone symbol and nothing happens. I've tried keeping my finger on the symbol, nothing. I try sliding the symbol over to center, but nothing.
Tapping only works sometimes; hitting it hard three times sometimes works
I'm a bit late but my solution will help another person. This was exactly my problem. The answer is really simple, if there's no middle icon to drag, TAP the green icon (don't touch or try to drag it)...thank me later.
