    Okay so, I bought this used iPhone 5s today and I found out it has a bizarre problem. It simply has trouble making and receiving calls. In the video you can see that it lags or something when I pressed dial, and once it starts dialing nothing happens (doesnt actually dial).
    I should add:
    - it receives calls but once the call is answered it will remain vibrating for an extra 10 seconds and nothing happens after.
    - the mic and speaker work well as I've tested them on Skype.
    - the phone reads the sim card as seen in the top right corner of screen.
    - it sends and receives texts perfectly fine.
    - 3g/4g works fine.
    - I've tried a hard reset and also restored the phone.
    - tried a different Sim card.

    I'd appreciate if anyone can help!

    brother it happened with one of my friend too, i have tested removing any other calling app, if u have any app for making calls then remove it, or else just use DFU and update the whole phone with new firmware.
    here is the link for DFU
