Why Is My Samsung Phone Lagging and Hanging So Much?

why samsung phone is lagging thumbs

If you have been using a Samsung smartphone for more than a decade, you have probably owned quite a number of Samsung smartphones. You probably have noticed that due to slight slowing down of Samsung smartphones roughly from 18 to 36 months duration or onward, it became the millennial’s habit to just change new phones assuming that phones are supposed to slow down as it is given the mentioned duration. Perhaps millennials are getting used with new marketing tactics, advertisements, and sorts of attractive offers along with the habitual social status for recognition.

It’s obvious that slowing down any smartphone can affect our emotions throughout the day. It gets more frustrating especially when we need to use the phone as simple as making a call, but it keeps hanging and slow till you feel it’s not usable. There are times where we would want to slam the phone on the floor whenever the phone hangs at the urgent time.

To prescribe the solution to fix Samsung phone lagging issues, we should understand why the phone is getting slower.

1. Samsung Was Powered With Two Different Processor:

Samsung comes in with 2 processors varied from countries dependent on the market. If your phone was powered with the Exynos processor, that can be the reason why it slows down and lag occasionally when compared to the other superior powered processor called, Qualcomm Snapdragon. Although both processors were compared most of the time, the faster superior Snapdragon variant in Samsung phones would feel smoother compared to Exynos powered Samsung phones.

Since Samsung’s plan is to avoid shortage of chips globally, therefore they implement Samsung phones to be powered with their own manufacturer’s CPU Exynos , instead of having an only external supplier of CPU Snapdragon from Qualcomm. This is why before you buy a Samsung phone, you should check on this post so that you are getting the one that suits you.

2. Samsung Operated with the Culprit of Android OS :

Samsung devices were operated with the Android mobile operating system. Android OS was developed by Google using JAVA programming language which is considered a resource consuming of a program language. If you are not a technical person, a simple way to say Android OS made from JAVA programming language for Samsung phones would generally require a significant amount of processing power and RAM. In comparison with Windows Mobile and Apple’s iOS system, you would be surprised that Android OS needs nearly double the processing speed and RAM to perform the similar task.

Android OS has another crucial drawback which is its heavy processing power utilization. The perfect example is Android’s user interface (UI) was not prioritized, reason being that when background apps or data was running, the UI data would run concurrently that leads to more processing speed needed. When that happens, the UI data gets little amount of processing speed left for when background apps data gets loaded heavily. Therefore, you may notice the UI data gets laggy, the icons, windows, graphic menu, gesture movements and more UI gets lagging eventually.

This issue obviously caused more lag eventually to newer phones, which is why you noticed RAM and CPU speed was drastically increased to cattle this issue for Android devices. You would eventually feel the new fast flagship Samsung phone after a year or more, it starts to get lagging when running more apps. Samsung’s direct competitor, Apple iOS, uses 1GB of RAM and could process more than what Samsung phones with 3GB RAM could do.

The most obvious cause of lag often does not come from CPU speed degraded over time, instead it’s caused by increasing software requirement over time, whereby more apps or software developers taking advantage of the advance speed in CPU, RAM and graphic performance. Therefore an older CPU on Samsung phones would eventually be required to do more work to run newer generations of apps and eventually gets to a point of too much limitation to handle, not to say how heavy Android OS with JAVA programming language crawls for CPU speed & RAM compared to iOS.

In most cases when a social media app such as Facebook or Tik Tok was running in the background silently updating newer feeds, while RAM was used as well in the background for this purpose. With more apps running in the background, when a much heavier app was loaded, you may expect to get a hang phone or ask to force close because of insufficient memory.

3. Samsung’s OneUi is Consuming Some Speed:

Samsung does not come with the default stock Android UI, they are implementing One UI on their phones. OneUI is known as the skin with icons, wallpaper etc. to differentiate Samsung Phone from other Android competitors.

Though with newer OneUI on most latest Samsung phones, it’s better than previous TouchWiz UI or Experience UI. However, most UI added to smartphones are known to be an extra skin and etc. of UI data implemented that would consume extra CPU speed and RAM size.

4. Software Optimization Was Not Prioritize:

Samsung puts its focus more on hardware rather than as a software company. Due to lack of understanding of the essential reason of software importance, code optimization on their device was not their highlight in long term.

Samsung keeps on releasing various ranges of smartphones every year. To catch up with the fast pace of Samsung phones release, the software engineering department was being pushed to deliver their task on time. They are required to fix any software bugs encountered expediently in order to meet the fast deadline. This is the reason why most software bugs are fixed quickly without proper optimized code. Therefore leading Samsungphones to laggy experience by just fixing issues primarily without keeping closer care of software performance optimization.

5. Samsung was Pre-installed with Bloatware:

Every OEM manufacturer including Samsung who wants to use Android OS with Google Play installed, they are mandated by Google to come with Google Apps that includes GMAIL, Google Drive, Chrome, Youtube, Google Maps, etc. Therefore to stay competitive in the Android OS in SAmsung smartphones, they came preinstalled with Samsung Internet Browser, Samsung Store, AR Zone, Samsung Cloud, Samsung Assistant (Bixby), Samsung Notes, Galaxy Theme and more. Moreover, you get the pre-installed third party apps that you are very familiar with such as Facebook, Your Phone Companion, OneDrive and few more, which are quite annoying that they can’t be uninstalled. If you care about sparing more storage or reducing memories, these bloatware are going to do the opposite for you.

These extra apps that run in the background would in fact slow down your Samsung phone a lot by consuming more RAM and CPU processing power. Bloatware for most smartphones on Android are known to be redundant because they should give options to uninstall it instead of forcing users to stick with it.

6. Samsung Abandon Ongoing Update After Certain Period:

Some of you may not know that Samsung phones only promise to update for at least 2 years. They mostly focus on newer smartphones which means 2 years older Samsung phones will not receive any update anymore.

You may have noticed continuous updates on Samsung phones for the first few times, where most updates fix the bugs happening in the OS which they have not yet fixed before the release. As the fixing of all bugs were near completion, the main focus would jump to newer Samsung smartphones substantially. Due to non-optimize code they release, the bugs on certain software may not be solved in some Samsung phones. This means there are some bugs that have not been fixed and it slows down the phone in the background crucially. Although Samsung is trying their best to fix any bugs happening on most phones, but some software bugs that users couldn’t reproduce it can be some bugs not being paid attention to and left behind to be fixed, while that as well consume some of the CPU power and RAM in the background undesirably.

7. Samsung is Slowing Down Phone Automatically:

You should understand that all smartphone’s batteries will deteriorate over a period of time and that is the nature of lithium ion batteries. As your new Samsung phone’s battery was new at first, eventually it would deteriorate and the Samsung phone would slow down its processor automatically to protect your phone’s battery. This automatic slowdown is to protect your battery’s life span.

There is nothing you can do with this kind of slow down intentionally to keep the battery’s health span longer. The only way to fix this is to change the battery into a new one. If not, your Samsung phone would get laggy with the decrease of CPU speed and expecting to hang at everytime when using your phone is a frustration.

8. Samsung Slow Down CPU If Battery Temperature Raised:

Most phones with powerful CPU and bright high refresh rate display would get too hot whenever being used for a period of time especially for those power intensive apps such as high end setting graphic intense games, high resolution photo and video editing. The battery temperature would as well increase caused by these parts which would trigger Samsung phones to automatically reduce the CPU processor speed to allow the battery to cool down. With such a factor, you are expecting Samsung phones to lag and hang to force close whenever in an intensive consumption.

Here are numbers of Top gaming phones that can cool down for intensive high end games.

9. Sluggish Performance When Apps Stored In MicroSD Memory Card:

Samsung phones allow the options to slot in a microSD memory card to extend the storage size. These microSD cards would face decrease in performance over a period of time with slower read and write operations. Whenever apps that were installed and stored in the microSD card, that could slow down the apps and can take longer than usual to load completely. This is why the iPhone does not condone the use of expansion of storage with a microSD card.

Best smartphones that come with large internal storage size 512GB to 1TB.


To summarize that, you could experience slow down and hangs while using Samsung phones, often due to various reasons. However these issues are common and always come with solutions to avoid Samsung phones from slowing down. Though there are various marketing strategies to prevent Samsung or Android phones from being laggy over some period of time, there are ways to counter that with a great solution. If our favorite smartphone brand is reliable and has been using them for such a long time, there is no reason to jump to its competitor thanks to Samsung’s continuous innovation to keep the fans excited.
