Touchscreen not responding

[Guest MiLiPa]

Hey guys,

 

Today, when coming back home, I dropped my phone and a thin (not that deep) crack appeared on the upper right side of the screen.

 

As the phone had no battery left, I just left it charging and tried to turn it on - the touchscreen isn't responding anymore.

 

It's not the first time it happens, mind you, last time it happened the phone had no battery and when I put it charging it wasn't responding. I figured it could be the same thing this time, but as it fell I'm worried...

 

I'm studying in Brazil right now, and I've got to use a smartphone to use WhatsApp and be in contact with everyone at home/people here, as free SMS aren't a thing in this place. I hope there's a way to fix this, so, let me know. And I'm not buying one here for overprice/warranty reasons.

 

I'm even willing to buy a new screen and try to fix it, but first I want to know about alternatives. Is there some sort of diagnosis I can make?

 

Thanks.
