On the iPhone 7 Plus, sends sliders are difficult to handle. No issues on iPad Air 3.
When trying to move send sliders on iPhone, it often doesn’t move at all with my thumb (being too large). I have to use a thinner finger to move them easily.
Very hard to move send slider with large finger, have to use thinner one.
Should be easily movable, the slider itself is graphically too thin, it should be modified or the touch interaction zone should be wider.
