Dude, shut your trap. I've been using my xperia z1 for the past 6 months and I haven't once experienced any sort of lag or stutter (or SLUTTER as you call it) on the stock launcher even when I used a live wall paper. As for your opinion that
"high End hardware is not worthy untell we dont have better Sofware" that is entirely BS. You can't exactly hope to run windows 8 which is a "better software" than its previous iterations on an age old computer that has Pentium II and has 256 MB of RAM and achieve high performance. Good Hardware is the most important requirement of any electronic device (Sony is the company that provides apple close to 100 million camera sensors that are used in its iphones). A software is built upon the hardware to utilize it in the most efficient way possible. That is the basic idea of software.
Your opinion about the z2 is of minor concern. No one cares what you think. People are going to buy a device based on its features, design and build quality all of which samsung (maker of plastic pieces of **bleep**) fails to provide. Samsung introduces features that are of little use to anyone in the real world and claims that these are new innovations just like what apple did when it introduced iphone 3gs with the ability to capture videos(WOW! what an innovative feature. No wonder samsung is being sued by apple) Most of the time, Samsung's stock bloatware is not used and the few times that a person actually does open these apps is due to mis-click(or touch). This survey by Strategy Analytics shows that these bloatware are mostly left unused. In fact, it clearly states that an average US user spends less than 6 seconds per month on its most trumpeted chat on app.
Coming to Design, You've stated that the Z2 is "just screen relacement and minor Design". What do you mean by that? Is it that the z2 Doesn't have any major changes in its deisgn compared to the previous flagships? If that is so, then what are we to make of Samsung(once again, the maker of plastic pieces of **bleep**)? It's design language hasn't changed much since the Galaxy S3 ( Galaxy S2 had an awesome design when compared with S3). Every phone that came out of samsung's(the maker of plastic pieces of **bleep**) factory ever since has had the same **bleep** design. While the same Plastic back doors, same curved edges and faux metal frame have remained the core of samsung's design for the past two years (22 months), Sony has seen an improvement in its product design. It has gone from the near **bleep**ty design of the xperia s to the most sexy omnibalance design of the xperia z, z1 and the z2. This clearly states sony's intention to modify and perfect their design unlike samsung( again, maker of plastic pieces of **bleep**).
As for the display, its not exactly a minor improvement. In fact, the display in the xperia z2 is light years ahead of the one in z1. The new display is much sharper, more vibrant, has better color reproduction and also higher contrast when compared with the display of the xperia z1. As an added bonus the new display also allows for wider viewing angles( which I care little about) than that of the z1's.
And also, Sony's build quality is top notch because the construction of the entire device is sturdy and uses premium materials when compared with samsung that uses the same piece of **bleep** plastic it always has. This shows samsung's reluctance to provide its customers with a more premium device because of its excissive greed to maximise its profits.
Finally, SONY's release of updates is less frequent because each update from SONY introduces major changes( compared to samsung) unlike the updates from samsung which are introduced for no other reason than to bump up the Android Version and Build number.
In conclusion, Every device has its own flaws. No device is free from them. You can't exactly be satisfied with a device when you already have pre concieved notions about how the device is going to be and how its going to perform just based on the company's past performance. I still hope for a day when I get to see samsung change its design language ( Galaxy s5 is a major disappointment) and to finally see samsung devices that actually make some sense ( Galaxy camera, Gear fit).
