I tried to change my lock screen yesterday, and turned off the screen. Later, when I tried to turned it on, the screen was frozen and seem dead. I tried to do the "press the power and volume button" trick, and it shut it down. I tried to turned it back on again, but then the screen was frozen on the home menu. It's still connected to the internet cause I still recieve notifications from LINE. The clock on the screen is also updated, and the alarm also still works. After I turned the screen back off again, I can't turned it back on again, it just frooze black. The phone keeps vibrating tho, i dont know why. Can somebody help me?
ps: i'm trying to fix it myself before i have to go to a store
