AgreedOk. Are you going to post ANYTHING constructive or is this the total knowledge you have on the subject?
For instance. In my extended family (grandparents, brothers, sisters, nephews etc) there 18 phones of which 5 are Iphones. The rest are Android of various types, sizes and ages. Only one person who owns an Android phone knows what a "launcher" is, or what "touchwiz" is, never mind understanding rooting and roms. These are the usual owners of Android phones - they don't root, they even change the launcher because they don't know how and don't see the point. They are quite happy with what came with the phone when they bought it.
The average Android user you get on this forum makes up a tiny percentage of the android market so don't judge based on this community.
So for 99% of Android users "tweaking" is moving the clock widget up a row , or adding a calendar to a second page. that's it. The other points about Ios being the best OS available - Well that's all subjective and perfectly fine, but it's an opinion, and not fact.
Most people who have the S7/S7 edge at work would look at you funny if you asked them what launcher you have on your phone or if he asked how you are finding touchwiz.
