Just recently my phone was laying on my night stand, and I revived a call at 3 am it woke me up and it was a wrong number but after that call I couldn't lock my screen, I didn't think about because it was 3 in the morning but then next day I couldn't turn my screen on, so now to get my screen on I have to plug in my charger, is there anyway I can fix this or do I have to take it to the store?
