I dropped my iphone and now its gone funny? What's happening?

Okay i got the glass on my phone repaired today and i just dropped my phone again! Anyways the screen went white with lines and then i held the on/off button and tried to switch it off. The white lines went then i went to turn it back on and now the screen is completely black and my phone keeps vibrating every 2 seconds. My parents are going to KILL me because they payed a lot to fix both sides of my phone this morning. Please please please can somebody help me

The connection has come loose

There's probably nothing you can do, take it to a phone mechanic get it repaired and when you get it back, get a good case and a screen protector for it.

Don't tell it you parents. Go to the previous shop again and tell him to repair it again for free
