Just got to use a bunch of brand new Galaxy S5's at work, and HOLY **** THOSE PHONES SUCKS BALLS, AND TOUCHWIZ IS A DISASTER OF A MESS.
I know the S5 is a year old, but my work just got a bunch of new S5's for the office today, and I had to set them up, and holy Jesus, does the S5 Touchwiz UI just blow. It felt like something from an S3 made three years ago. Super laggy, very ugly and outdated looking UI, like something from the Android 2.1 days.
I seriously had to check the phones, to make sure they were indeed S5's and not some S4 or older phone. They just felt so slow, ugly looking OS.
Granted, this is a fresh out of the box Sprint Galaxy S5, so it's needs updating, and a brand new phone is always laggy during setup, etc... But my God it just felt like an awful experience. No frigging way would I take an S5 for free. Just makes phones like the OnePlus One feel like light years apart, phones following more of the stock vanilla Android OS seems so much lighter, smoother, and overall look nicer. Why did Samsung keep this butt ugly Gingerbread theme in Touchwiz, even on the S5 ? And the menu is confusing on the S5, not straightforward like stock Android.
My point is, the new S6 better have a majorly revised Touchwiz, and completely all new UI, otherwise I don't care if the S6 is made from diamonds and sapphires, the Touchwiz UI will bring it down, if it's anything remotely close to horrible S5 Touchwiz.
