    Hi All,
    I m using a Lumia 720. And its been six months. And suddenly the keys at the bottom(the back key, home key, and the search key) is not working for a particular period of time. There is no response for almost two to three days and after that, it behaves normally for a week and the same problem continues.
    Can you please help me what might be the issue and whats the solution??
    Thanks in advance

    Hey can you please post your OS and firmware version , and try a soft reset by holding volume down + lock button at the same time until your phone vibrates and reboot itself (ignore the black screen to power off the phone ).
