I know, a premium phone can provide better camera photography,better music sound,better UI design,but .....
The calling function is the same !! It's a phone. not a multimedia device.
Maybe it's my habit matters.I don't want to do any extra things on my phone,except calling and texting a message. I prefer to playing games,watch videos.search the internet on my laptop or tablet.And listen to music with my Mp3 player while running.Take a photo with my Nikon while hiking outside.
Anyway,both budget phones and premium phones get their own users.They're just adjustable to the whole phone market.
I bought an iPhone 5s and it's stolen,big lose of money.And later I tried iRULU,Blu,Elephone,kinds of budget phones.Love them because they have basic requirements and battery life goes longer !! Everything gets simple ! Now I'm still using an iRULU V1,feels great.
