Apple said only nine customers complained of bent iPhone 6 Plus in response to reports of problems with the svelte but large smartphone.
The company defended the new phone's design as both "beautiful and sturdy," noting that its enclosure has been constructed of a special anodized aluminum that is tempered for extra strength and subjected to rigorous testing.
"We chose these high-quality materials and construction very carefully for their strength and durability.," Apple told Re/code. "We also perform rigorous tests throughout the entire development cycle including 3-point bending, pressure point cycling, sit, torsion, and user studies. iPhone 6 and iPhone 6 Plus meet or exceed all of our high quality standards to endure everyday, real life use."

Apple said that it's rare for one of its smartphones to bend — and just a tiny fraction of the 10 million devices have reported an issue. The company urged consumers to contact the company if they experience a problem.
