Hi Luthfie, Take a look at this guide, step 14, to reseat the connections, like Ben recommended. I think Ben is right. If you have followed Ben’s instructions but the problem is still there, you have to replace the digitizer/LCD. The corner that is not working any more might be the corner that hit the ground. So, this part of the digitizer might be gone. I would like to encourage you to at least try a repair yourself. You don’t need to be a real professional to do that. Just follow this guide here on ifixit. Give it a shot! Always keep in mind: First switch of your iPhone and then remove the battery next.
