I've got a samsung galaxy s7 for more than a year now and I didn't have any problems with that.
It's really resistent to drops since I've done that a lot of times and I'd also recommend one cover that you can find when you search for "samsung clear cover". (pic: (you need an account to see links))
Seriously it's one of the best covers ever, you don't even remember that your phone is wearing it and it's also very resistent, it helped me a lot.
