Touch
I have an iPhone X and it didn't fall out, however, right next to the edge of the right part of the screen, the touch works poorly ... I know how to solve this problem, it bothers me the most because of the keyboards

If you're sure that nothing (cover or screen protector) is obstructing / interfering with your touch screen (should be this case, remove them), try a forced restart of your iPhone, as per these instructions:--> Force restart iPhone – Apple Support.
If the issue persists, make an appointment and have your device inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> Apple – Location Selector
After checking it out, they'll give you all the available options.
