I got tired of replacing the screens on my Sony Ericsson. The last time I broke the screen on the same day I had replaced it.
That's another thing I don't like about smart phones... I routinely have to replace a flip phone a couple times a year... But it's a flip phone... Who cares, right? It's $25 and a half hour...
Get a few hundred bucks involved in a smart phone and drop it in a 5 of paint... lose it on the trail, leave it out in the rain all night, run it over with a tractor...
Even this S4, which in smart phone world, is already nearly antiquated, cost me 75 bucks... Lose or break that a couple times a year, and it's a whole different thing, not to mention the three or four hundred per phone to get anything decent.
And they don't store well on you either... They are prone to being in the way... prone toward destruction.
I wish you could tie two phones to one number. even if only one could be on at a time... I'd keep a flip phone around for rugged duty and keep that spendy smart phone in a drawer for around the house and town...
