Samsung phones suck
Imagine you buy a car.
It is a brand new car with shining reviews.
You walk up to it and try to get in - but you cannot find a door!
The salesperson tells you that this is such an advanced car that it does not have a door because you do not need it - you teleport
So, you press a button and - you teleport inside! And when you are done, you teleport outside.
You are excited and delighted and you use the car.
And then the car gets dirty - you know, crumbs and trash &c - and you want to vacuum it.
So you bring out your vacuum cleaner and ... THERE IS NO DOOR.
You can teleport inside, but not when the vacuum is plugged in.
So, there is no way to clean up the car - it remains dirty and you hate it.
When I connected my Motorolla Droid phone to a computer via USB, it behaved like a USB flash drive - any OS would connect to it and I can transfer the files to and from it as I see fit.
Now, Samsung phone are not like that. You have to download a special application (which, of course, exists only for THIS and THAT OS, but not for THOSE OSes) which has about 10% of functionality a normal file browser has.
Whoever designed this, I wish that you can never open any door yourself. You should always have to call Samsung tech support and have a technician visit you on-site and open the door for you.
