There are loads of comments about bloatware on this thread, I have asked this question before and never got an answer. What does bloatware do to the phone that affects it's performance that much that it will stop people buying the phone? All apps can be hidden so what is the big deal. Can some one please point it out to me. It is a serious question.
I've posted an answer to this a lot of times in this thread
Surplus apps that can be disabled or uninstalled are not the issue.
It's the hidden services and legacy that is underneath the hood on Touchwiz that contributes greatly to the big system overhead memory wise. A lot of these legacy apps and services actually have no correlation to apps available that once needed them.
Under the hood you have at least 50-60 direct Samsung services that run away whether you have uninstalled Samsung apps or not.
Much of these are from 2007!! Samsung Push for example was once used when ChatOn was their primary messaging app and yet still is there chugging away despite ChatOn being officially dead.
All this utter detritus under the hood contributes to why Samsung devices require 3x as much system ram allocated compared to a stock device or even HTC device.
These services are the ones that the makers of debloated Roms target and I've seen Roms where over 100 files like these were removed and it didn't affect the existing apps at all - which begs the question, why are they even there?
The answer is simple Samsung hasn't cleaned it's underwear in 7 years. Instead it simply puts on a new shiny pair over the top of the old one. Leaving crusty stained poop that should have no place in a modern OS still lurking.
This is the bloatware I object to. This is the bloatware you can not remove without rooting or running a custom rom.
Whether Samsung have one note or S-Voice on is not an issue, but this detritus hidden beneath is.
HTC were once heading in the same direction with Sense, however with the launch of the M7 they literally built their OS Sense 5 back up from a clean slate. They dumped every old rubbish under the hood. The result is Sense 5,6 & 7 run with about 400-500mb of system ram.
My Moto X 2014 runs around 250-350mb of system ram
Compare that to Samsung which routinely can have a device running at 1.4-1.8gb without any other app open .. You have a clear indication of what wearing dirty knickers does.
This is where Samsung needed to clear the slate instead of relying on bigger processors and faster ram each year to muscle through the septic tank beneath.
Sadly S6 & S6 Edge appear to have same stuff under the hood - Samsung has given Touchwiz another new shiny exterior - but again still same crusty pants below.
Now that doesn't mean the S6 & S6 Edge won't be fast - because clearly they are super fast processors and memory will power through the clogged drain without issue.
But devices like the S5 with 2gb did suffer - whilst the GUI is smooth enough at 95% of the time - after you open more than half a dozen apps - the S5 will often have to refresh the content of the older app aggressivly. Simply because of the OS without anything open sat at 1.4gb of 1.76gb available. Now imagine if they have brought the OS overhead down to 500-700mb - that would have left 5-6X as much free ram to users to keep apps open without having to refresh.
The S6 should be OK with 3GB - despite the overhead for system simply because that extra 1gb should fix a lot of issue the S5 had.
