I have warranty and need a camera lens repair( it’s cracked) is that covered

Not typically. Only if it's a stress crack that doesn't look like it's been dropped. Otherwise it sounds like it was accidental, which isn't covered by warranty.

My 3x camera zoom seems to be broken without any drop or accident kindly help me out does it repair in warranty and in case doesn’t repair in warranty how doesn’t it cost plz help it only seen when 3x zoom or above
