In less than 3 weeks the screen failed due to sun exposure. Cannot get a replacement during warranted period due to "mechanical" damage. No glass damage. Small crack visible in the AMOLED screen under the glass. Caused in my opinion by thermal expansion. The phone is flimsy at best and cannot withstand any torsional load. Phone was in an Otterbox case from the time it arrived at my home. I knew better than to get an untested early release product but I figured it was a good product because of the Samsung name. I wrote a letter to Samsung I don't know if they will do anything but it's worth a try.
