It doesn't happen on the Samsung Galaxy Notes
I've had the Note 1 and Note 3 (and will get a Note 5 next year) on the day of release.
I have constantly had the phone in suit & jeans pockets will no ill effects.
Making a phone rigid with a brittle screen larger (to copy other manufactors) and even more expensive to repair & insure will just mean the already significant number of folk with cracked screens will be joined by an increasing number of bent phones.
What with the raised camera-nipple it was never going to sit flat anyway.
