Not sure what you're saying. To paste I just tap to position cursor and long press to paste. Text selection on android is also less cumbersome without the manifying bubble like in iOS.
For ring tones just copy to the media folder and it will show up in selection. Or to remove just delete from there. Very simple without going through complicated itunes steps.
A nice thing especially with Samsung Androids is the Clipboard function, where you can copy multiple items without the latest erasing the previous item copied, some Android keyboards like TouchPal support this to, so that means I can copy multiple bits of texts and images e.g. when I copy/paste articles or quotes to a forum, to WhatsApp, Twitter etc... Without having to go back and forth, I can sit and paste all that I copied, my damn iPad can't do it thanks to limited iOS, but this has been a function since the Galaxy S2 in Samsungs.
EDIT:
Lets not forget Smart Select and Image Clip in the Note series, I can copy text and images from images, widgets, posters, FB, Twitter, Instagram etc... Anything that is on the screen I can copy without having to take a screenshot, I just highlight exactly what I want and boom, its in my clipboard, it will take what I select and break it down to Images, Text, Numbers etc... So if I go by a poster e.g. on FB, I can smart select the whole thing, my Note 4 will recognise contact numbers, Images and Addresses, and give them to me each broken down, so if I want just the address, I click on it and Google Maps opens up, I want the contact numbers? Hit Contact will allow me to save, call or share that number.
