Yean, I hate it too. The difference to selecting text on a desktop system is night and day especially because with a proper mouse you can shift click the desired start and end points and don’t even have to drag.

I’ve found that zooming in generally makes it more precise but that doesn’t help if it means that you now need to scroll the screen because of the zoom. For some reason drag-selecting text upwards also yields better results for me than downwards.

Another trick is to request the desktop version of a page instead of the mobile version and see if it’s easier there.
