IPhone 13 Pro - Rear Glass Protection

Hello everyone.

I was wondering if there is company that makes quality protection for the rear-glass of iPhone 13 Pro; something like the tempered glass that so many companies make for the front.

i do always have my phone in a case, but I get concerned because when I went to register my iPhone XS for trade in and double check the back by taking it out of the case I had found it was cracked all over and I handle it with care and never take it out of its case….given that it isn’t covered by any insurance either for cracked rear glass and is considered totaled I thought it worthwhile to investigate additional protection beyond a case and tempered front glass protection.

I did find a few on Amazon.com but they all appear to be brands Lacking established credibility.

Thanks in advance,

Sean
