When I wake my LG Magna with the power button, why does my LG Magna turn off?

[AC Question]

When i wake my lg magna with the power button my lg magna turn off?

When i wake my LG Magna with the power button my LG Magna turn off immediately, if i press the power button again and the my LG Magna turn off again. Even i force to release the battery and turn on again it doesn't change. Seems like the knock mode error, any solution? P.s 'I buy that phone just 2 days ago'. Thanks before

Welcome.

Return it to where you bought it.
