I have a Xperia e1 device. Recently on my phone 'phone' app doesn't work properly. I can open the app and go to contacts and recent calls but when I rereceive a call or I gave a call 'phone' app is start to crash. The app is close down and showing a popup massage 'unfortunately phone has stopped' This massage shows until the sender ends the call. But I can't answer to the call. I reset my phone but the problem didn't solved please help!
