Will updating from KitKat to Lollipop delete my data? I have a LENOVO A6000 running KitKat and I want to update it to Lollipop. I have important pictures and videos on my mobile.

Will my data be deleted or remain the same if I update my mobile?
If you're updating through your phone via an official update, the data will not be deleted...

However, if you're trying to update it manually it MAY be erased and you will need to take a backup
