Clients liability to pay for apples defects

So if your iPhone X has hardware issues, that is a manufactured defect and nothing to do with keeping my software up to date. My face recognition doesn’t work and my phone ghost touch’s all the time. Now I have to pay +-R12000 for something that I did not do wrong. For a world leading brand and product, this is the best you can do? Sorry we messed up and now the client has to pay for that. No not how it works.
