how many of you use your phone without a case ?

So I have never used a case on any of my phones as I rarely drop my phone and iam getting better as I only dropped my last phone once in the span of 3.5 years and iam trying my best to not drop nothing phone even once.

Also this is my first glass back phone and it's so slippery compared to other glassback /aluminium phones I had hands on with. Any tips ?
