Take out insurance today, wait a few weeks then make your claim saying it's just happened.
I did exactly that a few weeks ago when I dropped my Note 8 face down onto uneven concrete and shattered the screen. It was either paying Samsung £280 to replace the screen here in the UK or pay £75 excess to make an insurance claim. Happy to say the claim went successfully(ish). The repair centre lost my phone and after a week the insurers apologised and paid £879 + the £75 excess directly into my bank account so I could go buy a brand new one myself. Instead of that though I'm buying a Mate 10 Pro which is ridiculously cheap at £530 right now and l leaves me £350 change to go with it.
Just make sure you check the terms and conditions of the insurance policy first as some state you can't make a claim for the first 90 days etc
