cracked back screen

[newandroid]

Got my phone on the 24th november, great phone and livebit but when i set it down earlier (with no force, not onto any object etc) and when i picked it up again the back has cracked about 2 cm up from the bottom on the right handside, i have no idea why as i didnt drop it! Will i have to pay for this? Im baffled as to why it has cracked 😕
