Bull cr@p
ZR does not have that issue. I have dropped my ZR twice from waist level and sat on it several times. No damage at all.
Umm dude did you even read what issue i posted?
I said Xperia Z series has self cracking screen issue not fragile glass or something
self cracking screen issue is a design flaw of the bezels of the phone,not the glass
so i was not talking about dropping etc ,the glass cracks on its own without any incidents etc
heres proof that ZR also suffers from this
Regd: Xperia ZR Screen (PDA) warranty - Support forum
Sony will repair certain cracked displays for Xperia Z series suggests leaked info | Xperia Blog
maybe it wont affect everyone but its not just a stray issue,its still a concern though
