I have yet to come across a glass screen protector for curved screens which is viable. There will always be the issue of the protector eventually peeling off at the edges. Best option is to get a screen protector which covers the whole flat surface. This covers the 5T very well. The flat surface is mostly covered, with only the curved part of the screen not covered. The screen protector could have been slightly bigger to cover the whole flat surface, though this is being very picky. For the OnePlus 5T, this is the best protector by far. I've used 2 official OnePlus 5T protectors and both times the protector started peeling off.
