Galaxy S8 or S8+ feels sluggish? Try these 6 basic tips & tricks before you file a warranty claim

Well, stuff happens. You buy yourself a shiny new Android flagship and at first, you're all but awed by the raw performance that feels liberating. It's quite likely that for 95% of all users, the sense of using a proper high-end smartphone will continue for a long, long time. Yet, there is a fraction of the users that might run into specific issues, all of which could be attributed to lag and a general retardation of the handset. That will be especially true if you hog down the storage of the handset with tons of bloaty apps.

Sadly, all of that also applies to the Galaxy S8/S8+ as well.

Power users, tweak aficionados, and know-it-all tech heads, before you grab the pitchforks and torches with the intention of pointing them in our general direction, let us get things straight with a disclaimed - the following guide is mostly aimed at regular Joes and plain Janes that simply don't know their way around that good.

Samsung must revamp the UI again. Used an S8+ over the weekend and it's one of the most laggy current flagships on the market. The Pixel XL runs circles around it from a performance standpoint. I'll admit the S8 is a very attractive smartphone. It also has some great features. But paying ~$800 for a phone that has a lag issue in 2017 is insane. Hopefully they fix this before the Note 8 comes. No phone should require a user to adjust app usage to perform properly. Pathetic, and Samsung should be ashamed lol.

Agreed. When people say they don't experience lag on devices that have well documented facts on permanent issue they are kind of telling the truth. The thing is that they are used to it so they don't perceive it nearly as much. Once you use a device like a Pixel it becomes much apparent.

+1 Yup. It's a serious issue that needs to be resolved. People on this website don't realize how silly it is to pretend as if there is no issue, because then Samsung won't address it. Literally any person that goes from a Pixel or iPhone notices how much laggier a Samsung smartphone is.

One of the main reasons I can't own a Samsung as a daily. My primary phone is an iPhone, but have an Android as a second phone. I'm thinking about picking up a Pixel to add to the collection.

It's important to be objective in one's assessments. Objectivity is not a word synonymous with you.

...or anyone for that matter. All people have some degree of bias, and even your own comment suggests this.

No, you didn't, and no, it isn't. What it is, is the best rated phone in the world.

Nice trolling, you clearly haven't used one.

While I know many will jump to call you a "troll" or a "Samsung hater", I feel that you are absolutely correct in your statement. I like and respect Samsung in many ways. I've used many different phones over the years, and am currently using a GS7 Edge as my daily driver, but I can attest to this (slight) lag. All phones slow down slightly after a year or so of use, but I have noticed that Samsung just seems to have issues in this department a little more than most. I'm not gonna claim that it breaks the phone, or that it's unusable like some may claim, just that I've had to delete and tweak it in order to have it run as smoothly as, say, the Axon 7, which is another phone that I have here as a frame of reference. Again, I don't wanna sound like I'm bashing Samsung, as I feel they make some of the best phones overall, but their software, while truly feature packed and unique, does have slight (and i mean SLIGHT) performance drawbacks compared to other OEM offerings, and especially compared to stock Android.

You are welcome, although no need to thank me because if we're to be objective, then this must be said. I give praise where praise is due, but fairness also means acknowledging shortcomings and giving an honest critique when necessary.

Agreed. Too bad the fanboys won't believe in this and consider any kind of criticism as trolling.

Still no lag on my Galaxy S8+ Been using a OnePlus 3 for the past year and I also use a Pixel C, yet I haven't noticed any lag on the S8+. Strange that.

Having a Samsung phone does not guarantee that you will experience lag, it just increases the chance of it occurring due to their software coding. I did not experience any lag on my S7 Edge for the first 3-4 months either, but slowly, little by little, it started falling behind. Nothing major, but I had to "tweak" to make it as smooth as others. That's all. Still a phenomenal phone overall.

That's BS Skizzo. That's not my experience at all, they normally get faster due android updates. This isn't iOS, the updates improve performance, not make it worse.

I am very happy for you and your positive experience, truly, but saying that my statement is "BS" just because you disagree is not founded. There have been many discussions on the matter, and Samsung themselves have come forward stating that they will be working to improve their software, hence the reworking of TouchWiz into Grace UX, which is a big improvement, but the work needs to continue. I never stated that updates make it worse, only that it slows over time to to software coding (resource management, wriring/reading from internal/external hdd, etc.) So rather than saying that my statement is BS simply because you don't have a problem, let's just agree to disagree. That said, if Samsung continues making improvements to the software like they have been, they may just be completely "lag free" in the near future.

The worst phone I purchased.... Except for the design, screen, and camera; It is a piece of crap. Laggy and slow like forever. Never again, Samsung

Understandably. We all appreciate the honest feedback. I want a Samsung flagship in my phone rotation one day, but this ain't happening until lag issues are fixed. Let's hope Samsung not only addresses the issues, but fixes them soon.

Strange enough, I didn't do any of this and my phone is running almost perfectly. Apart from the stutter in animation that shows sometimes when I open the alp drawer, I'm yet to face any sort of lag this website keeps on talking about. As far as for those trolls in the comment sections who have never owned an S8, I say, try again.

You don't speak for everyone, majerk. Stop with the copout response "it's not a problem because it never happened to me." The S8 has lag in it and that's a proven fact.

Where did I say it run flawlessly? I'm pretty sure it's not me who's living in denial whenever someone talks about a phone from my favorite company having software issues. Every phone, PC, videogame will face lag at some time. It's just that this website and trolls like you act like this is exclusive to Samsung and Android devices, forgetting the fact that Apple releases an update to fix some issue every week or so.

This articles are talking about the frequency of the lag; if it happens every once in a while, it's ok, but if it happens more than a few times, it's no longer ok.

So does the iPhone, and that is a proven fact. So does the HTC U11, and that is a fact. So does...well, every computerized device in existence. It also happens to be minimal on all the devices I mentioned. In the S8 case, the overall package is enough for the phone to be the best rated phone in the market.

No, it still can't beat other phone - who shall remain unnamed - (the "best rated" means it addresses the most users; S8 may be "the best feature packed", "the best Android" etc, but not rated).

I haven't had any problems as of yet except for this site and one other that has all the adds. Adblocker took care of that. I had the same trouble with my note 5 and adblocker took care of it. Loving the best phone on the market, my s8+

Yep.. I never experienced lag on my exynos S8, apart from certain gaming experience (due to app optimalization). But navigating the phone is always a breeze for me.

Install a custom rom (preferably a debloated one) + a custom kernel + pray that it works = profit.

Losing out on things like Samsung Pay and/or Android Pay just to get a performance increase seems like a no-go for a lot of people.

Android Pay (not sure about Samsung Pay) works perfectly fine on a custom ROM (even if the custom ROM is rooted).
