Chosen Solution

The long and short is that I ran my phone over with my bike. Had I had a slighty more durable case, everything would be fine. The phone is otherwise flawless - a testament actually to the durability of the phone (something I thought I’d never say…). In any case, I see there are the lens replacements (with bezel) available from the store (see link). However, there are no guides to actually do this procedure. Is it worth my time or should I just install a new lens?

It’s not something you’ll want to do if you don’t need to. It’s a very delicate procedure. You’ll want to heat up the adhesive of the broken bezel enough so you can carefully remove all the broken glass and adhesive. Be very wary not to scratch the camera lens during glass removal. If you’re worried about scratching the camera lens, you can remove it prior to chipping the glass. Clean it up a little more with alcohol. Once the surface is clean, putting the new bezel on is pretty straight forward.
