Why is half my touch screen not responsive?

Hi Mathew,

Has anything happened to the phone recently, such as being dropped, banged or exposed to liquids? It sounds as though part of your touch screen has failed; there are fairly delicate connections between the flex cable that goes to the motherboard and the circuitry printed on the glass. It's fairly easy to disrupt those connections in the case of a physical impact of any sort, resulting in a failed digitizer - even though there may not be any break in the glass.

Your best bet for fixing the issue - assuming you've tried resetting, restoring and/or booting into safe mode - would be to replace the screen assembly that contains the digitizer. Sorry to say, iFixit doesn't have a guide to that repair for your phone, but the Spanish site NadieMeLlamaGallina.com has just what you need. The site is, as you might guess, written in Spanish, but if you use it with a browser that does translation like Chrome, it is quite usable no matter what your native language is.

Your phone is similar to many Android phones in that there are two ways to replace the screen. The one shown in the guide I linked to is the recommended way, which is to replace the screen and midframe as one piece; the screen comes already attached to the frame, so replacement essentially consists of gutting the phone and moving all of the internal components to the new frame. This isn't really as bad as it sounds, as the phone is designed to make that fairly straight-forward; far easier than it would be on, say, an iPhone.

The other method is to replace the screen alone without the midframe, but that requires an entirely different set of instructions; you can usually find something on YouTube. I've found that the price difference between a screen alone and the screen+midframe assembly is usually minor; most of the time the price difference will be offset by the need to buy glue to hold the new screen on, and then you have to rubber band it or put weight on it till it dries. The first method gives you better water resistance, as the screen is already glued to the frame for you.

Good luck with your repair, and be sure to come back and let us know how it all turns out for you. If you do go ahead and replace your screen, take lots of pictures as you work, and once you're done you can use them to create your very own iFixit guide for everyone who comes after you with the same problem!
