  • Hi zammwee03

    Thank you for your asking. Kindly provide the information below so that we could better assist you.

    1. Your current firmware version

    Settings>System>About Phone>Software information>Build Number

    If you try to update to the latest version, does the issue still remain?

    **My ZC554KL return and recent buttons work well in WW-15.2016.1907.519

    2. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.

    3. Does the issue appear after any system/apps download or upgrade?

  • Try to restore factory reset ur phone.Last week my phone experienced this and after alot of trial and errors to fix it i eventually decided to reset my phone and it worked.If its not fixed after that it might be a hardware problem.

  • If u are hesitant to factory reset it because u will definitely lose alot well just transfer ur important files to otger phone using shareit and pass it again after reset.
