Here's what I've done to all my phones.
Tossed them like bricks or balls in the air, missed many catches, no wonder am making cellphone companies rich.
I use my phones with oily hands, while eating chips or food (over here we eat with hands
)
Many a times, i pick many nose and then navigate on the phone, probably play angry birds.
I keep many keys and coins in the same pocket I keep my phone.
I don't apply a scratch guard, infact the first thing I do is remove a scratch guard from the phone.
Keep it on the edge of tables, with a vibrate + ring mode active.
Keep it on the table at hotels, a glass of water is curious to see my phone.
Honestly, I've done NONE of those and will never do, specially picking nose and touching phone, yuck!
But its true that over here we eat with hands and not forks/spoons, its preferred.
I apply a good screen guard, and a jacket (if I can find one coz I use models which aren't commercially avl. here) to my phone
, I don't let anyone touch it nor do I apply greasy or oily hands to it.
I periodically brush off the dirt on my phone.
I keep my current phone (Xperia T), inside a pouch in my right trouser pocket, nothing else
. Xperia has a full body gadgetzshield applied.
I am sure I must have caught a lot of attention.
