    EdenH, Jul 17, 2019 :
    I was navigating using Google Maps and suddenly the phone turned all blue and stuck on it until I hard reset it using the power button and volume up.
    When the phone turned on I noticed that the ring-tone has changed to default and also the custom ring tones (contacts) were deleted completely from the phone :(

    Please help

    As I mentioned, not all of my data was deleted, only the ringtones.
