1. The main problem is not with Samsung but Android.
Android doesn’t process data related to User Interface as a priority like iOS. Instead it lets UI data process along with general data. (In technical jargons, the UI thread isn’t processed as a priority). This leads to hiccups (lag) when normal data takes up more processing power and leaves little room for UI data to be processed and thus a delay in showing up the results of the input.
This is the prime reason for all that lag you face.

Another point related to Android’s UI is that it is developed using JAVA.
The problem with using JAVA is that it is very resource intensive and has problems with the way it processes garbage values in Android while UI and apps run, therefore requires much larger processing power than the contemporary OSs like Windows or iOS.
This over time exhausts available RAM and thus slows down the phone.

This is the exact reason why iOS and Windows run super smooth on low RAM but you always see Android flagships carrying 3GB of RAM. Users think it is for them to use whereas the reality is that it’s a fault of OS itself. It just can’t run smooth without using all of that RAM. Larger RAM needs larger battery life too. That’s why bigger batteries are found in Android handsets than in the other OS mobile phones.
All this just adds up to cost with no actual benefit to the user. Thus an Android Flagship costs significantly more than a Windows one. Pricing of iPhone is a different story. Their philosophy is to sell stones at the price of diamonds and make users feel special.
Yep! So the next time you see all those glossy advertisements smeared all over a newspaper’s page telling you how big their battery is and how cool they are to offer you 3 Gigs of RAM, remember that much of that isn’t for you to use. Android even after the recent Lollipop update just can’t run efficiently on low specs.

2. To top this, Samsung’s own UI i.e. TouchWiz further loads the mobile a lot and adds up to the lag.
This is why Android handsets from other OEM like Asus or custom ROMs like Cyanogen Mod based on stock Android UI continue to run smoother as times passes compared to Samsung’s having same specifications.
3. The app store is flooded with millions of applications. Many many of them are not properly optimized and efficient enough in the way they handle their cache.
Now the UI, apps etc. all run on JAVA byte code which requires translation to native language every time it is run. This increases the time frame between giving a command and Android displaying the results. This isn’t the case with iOS or Windows.
4. The type of flash memory used in modern devices is NAND/NOR driven (logic gates). This type of memory has limited life cycle and tends to get sluggish after repeated usage.
5. The last reason would be lack of optimization. 98% of Windows Phones are Lumias and all iOS mobiles are iPhones, designed and manufactured under close supervision of the respective companies i.e. Microsoft and Apple, which created the OS in first place. They optimize all the aspects of the handsets to make them run the OS smoothly and efficiently. Android is made by Google and manufactured by OEMs all over the world who further modify it. This adds up bloatware and less optimization leading to inefficient use of resources (RAM & Processor) thus Android starts to lag over time.
Edit 1: For the inquisitive minds who want clarification as to why Nexus devices don’t slow down as much as Samsung’s despite running Android, the answer is that Nexus devices are developed by Google itself. Google gives the contract to different OEMs (LG last year and Motorola this year for Nexus 6) and closely supervises the development and optimization of the device thus ensuring better performance. To top that, Nexus devices don’t use skins like TouchWiz etc. either.

Edit 2: New phones run smooth and get slow with time because they are simply new. They are running the best available OS version and all the apps are optimized for that version.
As time passes you update the OS and run Lollipop on a 2-year-old mob* with the specs that were capable for ICS. You start using Apps that are more demanding now because they have evolved to make use of those better specs**. Also not to forget how rubbish data keeps on accumulating in the memory too***.

*The date on which the mobile was announced is taken as the date of inception of product and not when you bought it. This is the ideal method, I’m not improvising. Often the latest mob you buy is already old by 2 months; at least in India where region specific product launches take time.
**Better specifications keep on trickling down to low end mobiles and thus a budget mobile starts to possess the specs of a high end mob. The updated apps treat these new specs as the base mark and ignore the fact that two-year-old low end isn’t the same as the present day low end mobile.
Take WhatsApp for instance, it got a complete makeover this May 2015 and introduced voice calling feature too. Added new animations. Apps just keep on evolving but your mobile phone doesn’t.
***Apps often leave traces of files/settings in the phone memory even after uninstalling them and thus a hard reset helps remove them and fasten mob.
And here you have the reasons why mobiles slow down with time but not instantly.
