My phone took a tumble while driving at work and everything was fine except the "d" key became super sensitive. Once pushed just repeats constantly until I hit a different key or get out of the app I'm in. It has even started repeating without me pushing it at all. Touching "e" or "x" is really dangerous! Makes typing near impossible. I'm seeing people talk about fixing the "p" key problem. Is this the same problem I'm now having with my "d" key? And if it is, is it fixable without replacing the whole keyboard?

The warranty is out of date. I've not had a problem I couldn't figure out on my own since it expired til now...

How much ould it cost to fix it if I have to replace it?
