Can't make calls, dial button does nothing, two "Phone" apps in app list

[DemiB]

Hi,

I've been searching for a similar problem all over the web and found nothing even a bit similar to this one.

I was still on kitkat on my xperia z2. One day, when trying to make a call, I just couln't anymore. Basically, I can bring up my contact list, recent calls etc. But when I go to press a contact, which would usually start ringing them, it does nothing. If I manually enter a number with the keypad and press the dial button - the keypad disappears and it isn't dialing.

I tried restarting my phone, which will then allow me to make calls as usual, but as soon as I close the "phone" app and open it back up again, same problem - pressing contacts/ dial buttons etc will just do nothing. Every time I restart my phone I can pretty much call someone once and that's it.

I went in to my apps list and founf something very strange - two standard "Phone" apps. I have no idea why there are two now, they are also different sizes (one is 1.11mb and the other is 2.0mb). I obvioustly cannot disable or uninstall either of them. I don't know if this is the problem.

I have updated to lollipop, thinking maybe that may help, but everything's exactly the same.

It's very frustrating as making a call is the ONE job I expect my phone to do without problems

Any help / suggestions are appreciated.

Thank you

I'd suggest that you do a PC Companion phone repair, this will do a clean installation of the latest firmware and will also wipe your internal memory.

Open PC companion -> Support zone -> Phone/tablet software update -> Repair my phone/tablet (blue link style). Follow the steps given, do not connect your phone until prompted to press volume down while plugging USB cable.
