S4 Constantly lagging

Hello,
I've had my Samsung Galaxy S4 for a number of years, since it came out actually, but I noticed within the last month, the phone has been lagging, A LOT.
The phone lags when I try to unlock it for use. I hit the home or power button and the screen quickly flashes on and goes off. I have to let it stay for a minute before it actually catches up with itself before I can unlock it and use it. Same when I try to lock it. I hit the power button and the screen freezes for a minute, and again, catches up with itself before locks and goes black.
It lags when I'm texting as well. The screen freezes and can't type anything, and again, have to let it stay for a bit before the phone catches up with itself.
Things to note or already tried:
-Factory reset. Issues still remains
-Photos, videos, music are all on the SD card (32gigs, 5gigs left of space)
-Internal memory card has 3.9 gigs of space left.
What could be causing this issue and how can I solve it??
Thanks!

I would suggest completely wiping the phone and internal storage, and then flash your current ROM with Odin.
If the problem persists, try a custom ROM.
I also heard from somebody that Facebook Messenger's chatheads make his phone lag.

pretty much to echo what @Pwnycorn says
pull SD card for testing;
factory reset and dont install any apps, just setup wizard.
check if lag persists.
install a few apps. does it occur yet? install more, try again, repeat
you'll track it down.

I heard custom ROMs are better and pretty much rid any problems that come with the phone. I just have no idea how to do it, as one tiny mistake and your phone is a brick.
I did turn off all animations. but I noticed since I changed keyboards to the Gboard (Google Keyboard) the phone's lag time has reduced significantly.
Only time it lags is when I switch to the default Messaging app.
Asides that, it works again. Strange how a keyboard can cause all this?

It's not necessarily the keyboard, it could be a certain update that went wrong.
And TouchWiz itself is a resource hog, ask anybody and they will tell you the same, except for TouchWiz fanboys.

Is it me or is the s8 slow?

I've been using my galaxy s8 (G950U) for about two weeks now. I feel like I've been ripped off. This thing gets warm just from streaming music via Pandora. Geekbench scores are better on both my Exynos s7 edge and my old note 5. Then there's the USB C audio lag. As soon as I plugged in usb c headphones, my s8 basically froze to the point of unusable. Anyone else having these problems or did I just happen to pick up a bad phone?

Havent noticed any of your issues.

I haven't tried USB-C headphones, but I am actually very satisfied with my phone apart from the battery. It's fast, responsive, handles everything I throw at it. Don't rely too​ much on benchmarks, it doesn't always represent the day to day use.

Haven't had it as long as you but i'm on day 4 and so far so good. Hopefully it stays that way.

I had an AT&T version and now an Exynos UK version. Both are incredibly responsive the latter more so. I spent hours yesterday with my phone connected to SideSync configuring it. Not a stutter or stall in anything I did. I can see how an S8 via Dex can emulate a PC. Your issues seem like a one-off. Most likely due to some combination of apps you have installed, something you've disabled or frozen, or a utility run amok (EG: Bixby re-mapper). Do you use SmartSwitch? Some apps don't like to be restored vs. installed fresh. As for USB-C I used it all day yesterday connected to a USB 3.0 port on my PC and regularly to connect my phone to Android Auto. The phone's performance never changed.
Here's how I configure my U.S. phones (it's not necessary on imports):
From a fresh restore from recovery I skip signing in to my Google and Samsung accounts.
I uninstall or disable all the carrier junk and any other apps I won't use.
I don't disable Samsung core apps because they're interdependent and can create problems and battery drain when they look for each other and they aren't there.
I sign in to my Samsung account and disable the syncs I don't use and then update all my pre-installed Samsung apps and download optional ones I use.
I sign in to my Google account and disable the syncs I don't use and quickly disable auto-update in the Play Store so I can control what's installed or updated.
Only after all my apps are in place do I start to play with the settings.
I backed up my AT&T S8+ to Samsung Cloud and only restored my apps, music, photos, documents, phone logs, and MMS history. Moving settings over is a crap shoot if something from the old phone incorrectly overlays something on the new phone. It's more time consuming to do it this way but (knock on wood) I've never had battery drain issues or any other funkiness with a new phone and I go through many. Good luck.

No problem
No problem here, really good performances overall.

Mine runs really well too. Very happy customer

Everything is ok here.. very fast

I have similar experience. My exynos S7E is way faster than this Snapdragon S8. Though I did get the UFS 2.0 version. Probably going to sell it and pick up another exynos.

Mine runs as slow as my galaxy s1...

I'm satisfied with mine. It's a beauty inside and outside ?

I only have the AT&T bloatware installed. I also transferred the same apps from my s7 edge to my s8, so I doubt it's any extra apps I installed. Could me having a UFS 2.0 have an effect?

Coming from a Google Pixel, I'd say animations and general smoothness/responsiveness are definitely not up there.
It's not slower, it's just jerkier. I wish Samsung gave the same attention to software polishing as it does with hardware.

it's the bixby button remapper apps
mine was fine, then i installed one of those. then the phone was so sluggish and jerky when scrolling
disabled the remapper, and it's buttery smooth again

it must be something you have installed.
do you have any other apps showing in settings>accessibility>services?

Mine is smooth and fast. I disabled the bixby apk's, but only so I didn't accidentally hit the bixby button, not because there was lag or anything. I turn off all animations/etc in developer settings on all my phones since the animations seem pointless. Fastest phone I have had to date, with the Note 7 right there with it. The s7E also very fast. Now going back to my Note 4 - BIG difference in speed, the Note 4 felt sluggish as any 3 year old phone would in comparison.

Very smooth. As fast as iPhone 7 I have.
Try Factory Reset

Phone is awesomely quick even on power saving mode.

I think this is your problem: some people reported issues when transferring programs and settings from one device to another using smart switch and claim all was well after resetting and installing everything fresh. I can't confirm it, since I didn't transfer anything from my old phone except phone book, but then I don't have any issues either.

very slow AT&T Galaxy S8

As you can see by the title, my S8 has been running very slowly recently. This problem has come up recently. Cleaning the memory through the settings only seems to be a temporary fix, and I would rather not root because I don't want to trip Knox. Is there any good apps or methods I can use to really get a good cleaning on my phone and speed it up?

Uninstall apps you don't use, use the device maintenance app built into the phone, clear cache and dalvik in recovery. That's pretty much all I can say without knowing exactly what you mean when you say "my phone is running slowly"

What is slowing my phone

my att galaxy s7 edge is running very slow from past few weeks, I tries to uninstall all new app but with no luck, is there way to figure out what is causing phone slowness.
Thanks

It's a Samsung device. It's part of the experience...
However, you can boot into recovery and clear the cache, which often restores normal performance. When you get back into the OS, you can finish by using Device Maintenance to flush the remaining caches. I try to make sure to do that at least twice a month or as needed.
Other than that, check the apps on your phone. Some apps are known to cause devices to slow down. I disabled Facebook, for example, and noticed an immediate improvement.

It just feels like the same issue as iphone has - where apple deliberately slowing down the system to preserve longer dying battery...

Why Galaxy S5 gets slow gradually?

My Galaxy S5 was getting super slow. Often I had to wait 10 seconds or so that it reacts to my touches. I had the latest manufacturer rom installed.
I reinstalled Kitkat manufacturer rom and the device got as fast as original.
So my question is why the device got slow or how could measure what is causing these problems? I have noticed similar effect on other phones, when the same rom is installed for a long period of time.

Too much cache and datas. Try first of all wipe cache from recovery mode and do it once a week. If neither this will work, wipe data (factory restore) always from recovery mode and the phone comes responsive like new untill to much data and caches will slow it again. Don't install to many apps, even this slowers the phone. This happens even on KitKat.

You could also try to install an app called KernelTuner and see if the cpu is always on high load.
Is the battery draining fast or is the touch screen just unresponsive? But there are a lot of possibilities for this issue and if everything is falling apart you could switch to a custom Rom or buy a new phone.

I have the same problem with G900F which is SUPER SLOW after official Marshmallow 6.0.1 update. Stock Rom. It is the worst and slowest Android exprerince I've had so far. Is the solution installing custom Rom if there is any reliable and safe one?

Just install lineage os or debloated stock problem solved

There was/is an issue with the contacts db blowing up to gigantic size which had/has an impact on performance & stability.
My S5 was not affected, and i've been using 6.0. 1 for at least a year.
But today you can expect such behaviour on various occasions with a phone that has only 2GB of ram and a Snapdragon 801(which should still be competitive with the MediaTek SoCs in cheap phones, at least.).
E.g. my fav weather app WetterOnline becomes a resource hog sometimes on my S5 till the dreaded "app not responding" message, but not on my more powerful LG G6, and on other occasions the app runs super smooth again.
Something as basic and simple as a weather app should perform well on any device except the oldest or most basic ones.

My S5 became snappy after downgrading to Lollipop. Keep in mind it came with Marshmallow when I bought it brand new.
