Same goes for the frame? that people are getting cracks/breaks in, due to temperature changes I feel. If this is true and the trend continues and escalates in future S phones, Samsung will have rough years ahead.
The key is probably the display itself is providing a lot the actual structure support due to less bezel and more glass. This means the kinetic energy gets displaced even more to the display. Since glass is the weakest structure as far as elasticity on the device- crack attack!
Added: A case would be a good investment for the S4.
