I just buy durable phones, I very rarely drop them nowadays but if I do the worst that happens is a scratch or dent. Last two times I’ve broken a phone have been jumping in a pool forgetting it was in my pocket (usually buy waterproof for this reason) and falling on a rock with it in my pocket
First one no case would have prevented short of one of the ultra rugged outdoorsey ones, second one only the cases with the front cover flap thing might have stopped
Only time I’ve broken a phone by dropping it is when I had an iPhone 4 handmedown, I swear those things were designed to break
