ui system

    hi all. I have a Samsung Galaxy Note 4. it was working fine untill a couple of weeks ago. the problem is that when someone rings me it will not let answer the call. it displays a message saying unfortunately ui system has failed
    does anyone know how to fix this as it is quite annoying. thanks


    No. But I'd back it up, factory reset and rebuild it.

    Try a factory reset.

    Did your previously installed apps redownload? might be one them causing it.

    Hold volume up or down with power button and boot into recovery mode.

    Try booting inro safe mode and see if it happens.

    If it works fine, could be a recent install causing it to crash, maybe an app accessing the dialler.

    Also clear the cache in the recovery options, I am 90% certain it will fix the issue
