iPhone 6 Plus users are reporting bending problems with their devices just a few days after the launch.

After the iPhone 6 Plus was unveiled by Apple, the main concern among potential buyers revolved around the size and whether or not it would fit inside pockets, writes Lisa Eadicicco of Business Insider.

"Now, as it turns out, those who can fit the phone in their pocket are reportedly complaining that the phone bends after being stored there while sitting," says Eadicicco in her article.

Several commenters in the MacRumors forums report having their iPhone 6 Plus devices bent after carrying them around inside their pockets.

"I received my iPhone 6 Plus 64GB spacegray at about 3pm on Friday and set it up, but haven't worn it out that day, so it wasn't in my pocket. Yesterday, I left at 10am with the iPhone in my left FRONT pocket of my suit pants... in total, the 6 Plus was about 18 hours in my pocket while sitting mostly," writes a commenter in the forums.

"As I lay it on the coffee table and sat down on the couch to relax from the drive (yes, sitting again ), I saw the reflection of the window in the iPhones slightly distorted. Now I lay it flat with the display side on the table, take a look. Maybe at 5.5" it is too thin?"

The blame can be put mostly on the materials used to build the iPhone 6 Plus, writes Sean Buckley of Engadget.

"Some say that extra-tight jeans are to blame, but it's really an issue of building materials -- the iPhone 6 and 6+ feature an aluminum chassis spread over a wider area than any previous iPhone," Buckley writes.

"Aluminum is a naturally soft metal; with enough pressure and leverage, it's going to bend, and some owners reported similar issues with the iPhone 5. Metallurgy aside, though, it's still a potential drawback for Apple users thinking of upgrading."
