Keyboard key registers my touch on the key below it. What to do?

[htcemeight]

I have a Verizon HTC One M8 and recently the keyboard letter O registers my touch on the letter below it (K). It does this in the portrait mode, but not landscape mode. It also does it when the keyboard is switched to numbers, and then the 9 key (in the same position as O) registers my touch on the key below it (the ?). It appears to only happen when I touch in the direct middle of the letter, if I touch near the top of the letter square, or the bottom or either side, it seems to work correctly. I have recalibrated the keyboard, Ive tried an app keyboard (swiftkey), Ive cleared cache, Ive uninstalled and reinstalled, and Ive done a factory reset and nothing has solved the problem. Has this happened to anyone else, and what was the solution that fixed it?

Welcome to Android Central! Do you have a screen protector on?

Thanks! No I dont have a screen protector.

Edited to add that I've downloaded Screen Touch Test app and it is showing that dots are appearing in the K key area (which is below the area I physically touch which is where the O key would be), supporting my thinking that the touch registration is offbase in that particular area. Sometimes a dot appears where it should in the O key area with no dot appearing in the K key area, and sometimes the touch does not register in the the O key but only registers in the K key area.

It might be a hardware problem with the digitizer, then, which might require the digitizer/screen to be replaced. Does it happen in Safe Mode as well? https://support.t-mobile.com/docs/DOC-10853

Thanks for the link. Yes it still happens in safe mode. I tried typing in Google, messenger, and Calendar and got the same results.

I think you may not have any other choice but to bring it to a repair shop. Sorry!
