S8 is laughably slow - Samsung Galaxy S8 Questions and Answers

I have an unlocked s8 G950U (US snapdragon) model and it's laughably slow. For instance I can have an app open and the phone will grind to a halt when a call comes in unable to accept or reject it for 5 seconds or so. It runs fine but the responsiveness is not there.
Typically I would take a phone flash a custom rom on it and tweak the kernel to get it to work right. It's my understanding that the locked bootloader will greatly limit what I can do in this regard, so the best I can do is flash the same factory rom again.
Does anyone have any recommendations for this issue? Am I expecting too much?

Mine runs unbelievably fast I even have it underclocked some bassicly stock rooted and debloated
only lag I ever see is opening the notif bar

no such issue here for me, one of the fastest and smoothest phones i've ever held in my hand, would recommend a factory reset or at least cache clearing from recovery, it helps to do it from time to time

I'm sure that would help but the phone is 2 months old. Factory resets every two months would be horrid, at least we have an SD card slot so I can keep all my documents there during the reset..

if the phone is only 2 months old then there is something wrong, my first factory reset was after 8 months of purchasing the device and it wasn't out of lag or it not being responsive, maybe you should try a factory reset or maybe a different firmware ( an official one ) to see if the problem is solved even after 2 months of using
and you don't have to necessary lose your data, with smart switch you can backup everything, except apps data itself, but pretty much everything else from call logs to apps, photos and music on both phone and SD card can be backed up and restored in minutes

No such issues here. The phone is smooth as melted butter. Am on Oreo beta. SE 9.0 is much better than SE 8

try a settings reset in settings, might help, together with clearing cache.

Than hold one oneplus5T haha kills the s8

It's pretty sad that the user who paid close to a thousand dollars has to resort to wiping their data, because Samsung is so incompetent at creating software that stays smooth after use...
My device has never been wiped and I got it on the 20th of April last year, battery life is excellent as always, but app opening animations are 20 fps and the UI stutters when doing normal things like switching between apps. It'll be interesting to see what the Oreo / SE9.0 update does for smoothness, I might even think of doing a factory reset if performance doesn't improve after the update.

i didn't really like it. its not a matter of just how smooth and fast the device runs, but for me as for overall features, s8 is the best phone in the market right now

Why HK users have so many issues after upgrading to ICS?

Hello, I have been waiting for Samsung HK to release the ICS before purchase. Within a day after the release, lots of users in HK have complained several issues. I tried a Galaxy Note with ICS in a local store, the response of that device was like 50% slower than that before the upgrade. How come even the hardware is the same, some users have more problems than the others (with respect to locally and globally)?
Probably because those ppl upgrading didn't wipe after the ICS upgrade.
When I tried out the LPY rom without wiping, it did really feel like everything was noticeably slower.
Wiping sorted out the performance issue for me. Of course, Samsung should really ensure that users don't really have to wipe to get peak performance post upgrade to ICS..

Just keep going on and tell ppl to wipe with the buggy ics kernels..........
Samsung might send you medal of honour for that..
I read that they have the following problems. At this stage, do you recommend buying the Note only if it has ICS pre-installed or wait until Samsung HK has fixed the bugs? (Not sure if the Note with ICS pre-installed has these problems.) Why Samsung does not release the same ICS to different countries?
- "Google Map always force close during the time of GPS location "
- Cannot receive signals from routers of 5GHz
- Front camera changed from 2M pixels to 1.3 M pixels
- Very slow response over all. (My experience is about 50% drop in speed overall.)
- Poor battery performance
- High RAM usage
- Becomes very hot easily
- GPS disappeared (not sure as I don't read Chinese well).
- Some kind of mess up with music files (not sure as I don't read Chinese well).

Like dude above said, wiping throught cwm or even stock wipe/factory reset on any ics, except cm9 is not safe. It can brick your phone.

I often read the word "brick" in forums related to Android phones. Is that the same as breaking the phone into an useless state?

A brick is a building stone for your house, slang for unusable. In case of ics it can render broken mmc chip, thus making it nearly impossible to fix for ordinairy consumers.
You have softbricks and hard bricks. In case of ics chance of hard brick is higher

Just from my personal experience, I haven't noticed any of that even though I installed ICS without wiping/factory reset. My Note is no slower since upgrading from GB, it gets no hotter, GPS still works with Google Maps, the battery lasts the same as it did on GB, the RAM usage is no higher, the front camera looks exactly the same in Skype, and my music works just the same as it did before.

Somewhere in Hong Kong. I live in Shanghai, but I didn't want to buy the Chinese model Note, so I got my brother-in-law to buy it for me when he went to Hong Kong in April.

Yes, definitely. There were a lot of changes (fonts, face unlock, Settings in the status pulldown menu, etc) and of course it says Android version 4.03 in the 'About Phone' section of Settings.
My gf's phone is a rooted Note. Yesterday she saw a notification for firmware upgrade, which I dismissed just in case. If I install the update, will it lose root/CWM? How could I re-root it back? Is this software update affected by the brick thing when you wipe? Thank you!

Excuse me! I am new to Android. What is mean by "wiping"?
I suppose "rooting" is similar to "jail breaking" in iPhone term. Am I right?
Do people who have "rooted" their phone have more issues after upgrading to ICS? Thanks.
My first time upgrade from 2.3.6 to 4.0.3 = lagging like hell and battery hog!
Then I had it reset to factory settings from menu. = no more lagm or lesser lag i should say. But battery hog still.
Then i did a hard reset (pressing volume button + power button + center button when my mobile off) = battery works a bit better now but still a bit hog.

Yes, you will lose root and CWM. You can root and get back CWM after updating if you choose to. dr. ketan's mega thread explains how. I rooted after updating but chose not to install CWM.
For those of you who still haven't received the update, you might not get it OTA (from my personal experience). My phone found no update OTA, but instantly informed me of the update when I checked with Kies, so make sure to check both methods.
I didn't wipe after upgrading to ICS, not sure I want to yet. My personal observations are: battery life is a lot better (phone switches to sleep a lot faster now), reception/signal is much better, and the stylus accuracy is better. I've noticed no bugs with Maps or Music (though I haven't tried using GPS with Maps yet).
The bad things I've come across: 1) I've noticed so far is some very noticeable lag/sluggish touchscreen response, especially when clicking apps/buttons on the screen and any scrolling gestures. It's especially noticeable after waking the phone. 2) RAM load is also noticeably higher than before under normal usage (~100-200 MB more). 3) The phone takes a lot longer to perform "media scanning" after turning on. 4) A minor thing I've noticed is the phone takes a couple of seconds longer to shut down lol. Other than these 4 issues, my phone has been fine.
EDIT: I've found minor bug with the Music player - custom playlists randomly get deleted by the phone...major pain to redo them all. And I can't find where the phone saves them so I could at least try to back them up.

Something better for my S5?

I have to say, I am almost done with vendor/carrier Android phones. I have had the S2, LG G2x, S3, HTC One X+, and now the Verizon S5, which was my choice of over the iPhone 5s for my corporate phone.
I have not done anything to my S5 yet, haven't installed a boat load of apps, nor does my company run any fancy, MDM work/play management software, and still this phone already feels bloated after a couple months of use. The lockscreen sometime takes many seconds to show up, only then to immediately disappear before I can even enter my lock pattern or swipe my fingerprint. And boy, does the fingerprint reader really blow compared to the iPhone. Try unlocking the phone while on the go with the fingerprint read... nearly impossible. The camera, wow sometimes takes over 20s to load. I thought going from a 1GB RAM phone to 2GB phone would make a difference. Needless to say the Samsung and Verizon bloatware finds way of eating resources up fast.
I'm stuck with this phone, and once again, it looks like I'll need to root and load a custom ROM to get this POS to run like a respectable smartphone. I'm capable and have done this to all my Android devices before (except my Nexus 7), but quite frankly I am tired of this and all the time I have spent, unlocking, downloading, backing up and loading and unloading ROMs. I only wish, there was a Google Play edition for Verizon or, I should just buy my own Nexus 6 when it comes out.
In meantime, what is the best recommendation of the clean/stripped/no frills ROM that will make my phone run and look most like a Nexus device?
Sorry for the rant, I'm not planning to go over to the fruity side either. So you guys are stuck with me.

First thing I did out of the box was root, install Titanium Backup Pro and freeze everything that was not system dependent. I run supersu and Xposed framework with Wanam and some other modules. The phone has zero lag and the battery life is insanely great ... I've never had an android phone (my 4th) with such incredible battery life. I am so far beyond impressed with this phone it's un-real.
Good point. And my point is, ultimately I am needing to at minimum as you suggest root and freeze with Titanium backup, which at least a bit less of time waste than installing a new ROM. That said, I mind as well while I'm at, since I really don't find anything redeeming about Touchwiz. The bigger point, I can't imagine a non-technical user wanting to do this over-and-over again for each Android phone they get.
I agree battery life is very good, even stock. I'm running in power saving mode. That is the only redeeming quality I have found so far...

Power savings mode throttles down the CPU around 30% and dims the screen. This is no way should cause the lockscreen to take over 5s to pop up or the camera 20s to load. I am not playing any 3D games or anything like this. I'm pretty sure it's just bloated software eating away at the 2GB of RAM.
My HTC One X+ never slowed to a crawl like this on power saving mode. The issue with that phone was the battery life and hence...power savings mode.

Not experiencing any of the problems you have man. INSANE battery life, extremely snappy performance, I personally have grown to like touchwiz alot. Why dont you at the very least just do a fresh flash with stock firmware and it'll fix alot of your issues or go install one of the roms like SLIMHYDE and youll never have those issues again unless the above poster was right and you just have a bad phone, which is easy to get replaced.

Probably only a slight possibility my phone is defective. Usually things speed back up if I reboot the phone. But things slow to crawl usually after about 2 days of use.
I can definitely try to do a clean reset, freeze apps, install new ROM, etc. My point is, I really shouldn't need to do this for a top of line smartphone. Again, the only Android device that hasn't presented these issues and I am happy to run stock is my Nexus 7. I guess I should save some pennies for the Nexus 6 phone...great way to suck more $$ out of me.

Dude, I feel your pain. This will be my last Samsung device because of their dogsh*t software and locked hardware. The phone slows down over time, there is no doubt. The only great thing about the S5 is the hardware, putting CM would have made it by FAR the best phone out.
Regardless, I have rooted and debloated. I have enabled Wifi tethering, enabled voice recording, etc. For the most part I am pretty satisfied right now.
I am waiting for the next version of the LG phone, G4 maybe? Or a clean Google phone on Verizon.

Anyone else having performance issues with their S7 edge?

I got my S7 edge a few weeks after release, and it's always performed worse than my other phones; however, in the last few weeks, it's become extremely slow. There are tons of frame drops, and my other phones (2015 and 2016 flagships) consistently perform better. For example, I sometimes have to wait 2-3 seconds for recent apps to load after I press the recent apps key. I'm on the latest update, just reset the phone, and don't have any particularly intensive apps.
Do you guys have any tips to make the phone quicker?
Yeah me too. While the phone is awesome to look at and hold and it takes awesome pics the user experience isn't all that great. It is no quicker or snappier than my G4 or M9. Actually it's quite slower at times and the memory management sucks. I'm constantly getting freezes and lags and for a while random reboots. Probably a TW/bloat thing because the hardware is more than capable. Once or twice a day I've been booting into Recovery and wiping the cache. That seems to help some.

Hmm, okay. Glad to see I'm not the only one with this problem.
Yeah that's always reassuring just sucks because this is almost a masterpiece. It's a shame that TW and other crap is dragging it down and not being able to root without giving up useful functions blows. And from what I'm hearing rooting doesn't help all that much. Not that it ever did for me with Samsung phones. I guess that was the reason I stayed away since the Note 2. There is a program that let's you disable some of the bloat without root and it sounds like it helps. Maybe you can give it a try. I bought the Pro version but been a little wary since I can't just reflash and start over if I screw something up. It's in the Market and it's been featured on xda TV. It's called Package Disabler Pro
Mine just dies really fast after rooting
I am on the U firmware and don't have any of those performance issues. Plus I use nova launcher so idk if that has anything to do with it
None of what you are describing is normal. I have my S7 edge on the 7.0 beta and the only time I have seen that behavior is when download booster is enabled, which is beta related/stable on 6.0...
I also had a friend tell me the same thing was going on with hers, I made sure the T-Mobile app was not running any diagnostics and that all accounts were syncing properly. After checking those two things the stove inside turned off and performance was restored.
tl;dr NO, it's not because of TouchWiz. Something is not right with your accounts or an app.
I don't root my Samsung phones anymore because its not been necessary for me since the Note5, my Samsung devices have performed flawlessly through updates, backups and restores for over a year now including my S7e, Note7:crying:, and after several updates, S6e, on stock unrooted firmware, no PDP either.

Top much lag

Hi my friends, well... I write this thread because I want to know if you are in the same situation. 2 weaks ago my cellphone becomes laggy and I don't know why, it was fast and when I felt that it turned slow I did a factory reset and it didn't works...

Mine did the same thing after the last update, I think android just sucks at not getting laggy, not sure why google wont take this stuff seriously.

That's not a Google problem. There are hundreds of possibilities why the phone becomes slow. Without providing any useful information, help impossible. So better to write some facts about the phone model, bootloader status, and what rom and other things you flashed. Then we can have a look.
I just turned on Battery Saver & Lag Is Gone my phone is flying. I have no idea why (I know it turns some sync stuff). I just find the speed change interesting. I am running Stock 6.0.1 Marshmallow. On a G Plus XT1644.
Try it out Settings>Battery>3 Dots Top Right>Battery Saver> Turn On.

Yes! same as me , but I didn't update anything, just like that boom is really slow, I tried everything, clean storage, wipe cache, wipe dalvik, delete some apps, check wakelocks, I don't know what to do, don't want to factory reset the whole thing!
To be honest, I never found this phone to be really lagging. I always owned budget phones and this has been the best one yet.
Yea the heating issue in sd 617 can't be appreciated much though.
Got serious lag issues with my phone. At times it is zipping fast.. and st times it makes me wait for couple of minutes just to dial a number. Tried everything under the sun

Terrible performance after Galaxy S8 SM-G950U One UI/Pie update

Hi all,
My phone performance is terrible, everything runs slow and lagging since I took the update. Phone performance was very good before. Anyone else experience this and have any ideas to bring performance back to par?
Thanks for any help.
Factory reset or full wipe after updating to a new firmware. Also, do not restore Google apps, just start from a scratch.
I also have serious lag, it feels like a budget phone. I've had this phone since it launched, and installed every update without precaution. This is the first time experiencing these issues.
Frame rate is terrible, especially while scrolling. Delays in pressing buttons or launching apps have grown from milliseconds to sometimes two or three seconds. No other problems(aside from poor design choices). It feels like aggressive power throttling, not memory issues.
As soon as I saw that so much manual power management has been replaced by a "learning" system, I'm skeptical that the usual fixes will do anything for my problems, especially considering there is no other malfunction. Anyone else?

Hi all,
My phone performance is terrible, everything runs slow and lagging since I took the update. Phone performance was very good before. Anyone else experience this and have any ideas to bring performance back to par?
Thanks for any help.

Samsung Galaxy s8 SM-G950W. Yes. Ever since the update, my Samsung is losing files., running slow and unable to use previously used apps. Substranum, fonts etc.
It's Samsung way of saying - "Buy galaxy S10"
I didn't fell any difference at all in performance.

Well, that's what I was waiting to hear. If ppl aren't universally having the issue, then a factory reset may cure the problem. I'll give it a try soon.
Yes i just got bad performance after installing pie (custom rom, so i always factory reset or it wont work) but yeah after 14 days my phone start to slowing down like old smartphone and the apps is not starting correctly (e.g i must start magisk manually or the root wont work (the app cant detect if phone is rooted even when magisk hide is off)).
I try the LightROM and ALEXIS and both have this problem (performance way worse on lightrom). I know this isnt their fault but the samsung fault (maybe because its early relase? Or...).
Note : performance is normal in the first day, but after 14-30 days the phone start to acting weirdly (the apps behave weirdly) dunno why.
Btw i use SM-G950FD
After restarting about 5 times, then manually clearing cache partition, I was able to get smooth performance. Unfortunately, I still have to restart at least once a day to prevent lagging animation. This is with light usage: streaming, facebook, email.
I turned on "reduce animations" in advanced features, and set the animation scales to 1.5 with dev options. This seems to help prolong smooth operation, but I still have to restart daily. Next step is factory reset, I have a lot to backup...
fresh install thru odin and start all over again is really good solution. at the beginning i also experiencing lag
Mine has an issue of having the fingerprint not working after it was changed. I have to do one of the following:
1. Restart and boot via safe mode then if it works, reboot again
2. Restore Settings from synced backup
3. Reset Settings
So much of a hassle.... I am thinking of rooting this soon.

Had the same problem so flashed official firmware (for my carrier, downloaded from sammobile) with Odin. This part can be done without of rooting your phone.
Do this first (back up your data before as clear flash will delete everything), and test after if it works well. If not, root it (https://forum.xda-developers.com/sa...w-to/guide-root-install-twrp-samsung-t3747535) and install adaway from xda labs.
If you root the phone or install TWRP, e-fuse will break and you cannot go back after that. Warranty will be void and the Samsung fit app won't work anymore.
Fortunately, there are workarounds on a rooted phone (https://tinyurl.com/yy37gnwv) so that is not a big deal, at least for me.
Not sure when you root it if wave pay services will work so do some research first.

Has your lag subsided after time? Mine appears after a night's sleep. It never fails: Restart in the morning, smooth scrolling all day. Next morning, laggy, stuttering scrolling until I restart again. I've uninstalled all unused apps and left power mode on high performance. No change. As soon as I wake up, animation lags like a budget phone. Everything else is reliable, just not the animation.
Of course, I don't actually know what's going on, but I'm willing to bet that this new power management system that we can't control is to blame. If I have to go through all the odin, etc steps, I may just roll back to oreo. Pie is prettier, but I want my smooth operation back.

S10e gets similar reception to my A8(2018). When I got the A8 I had a S8 before that, and i don't remember there being any difference in signal. I live in poor signal area, so if a phone had bad signal, I'd probably remember because I owuldn't have any signal at all.
This is really quite unacceptable. I took the OTA update and the lagging began. I've never had an issue with an OTA update. I've never done a factory reset after an OTA update either. Flashing custom ROM is different but this is from Samsung...
Does anyone have a solution that doesn't involve daily reboots or a factory reset? I just find that really inconvenient.

Yes, I agree. It's hard to know at whom who to point the finger. Google, Samsung, or both. Regardless, it's very disappointing, and hurts my impression of both companies.
I'm currently allowing the phone to run for 7 days to see if the root method listed above by robyos may be feasible for my tmo s8.
If manually restarting is the only hurdle for you, it can now be set to restart automatically (I guess they anticipated this?) Settings > device care > three dots > auto restart.
It feels like a duct-tape band-aid, but it's there. After my 7 day test, I'll probably give this auto-restart a try. However, I'm concerned about the terribly annoying tmo jingle at each restart.

I'm thinking the problem may be googles not Samsung's...I had a OnePlus 5 for almost 2 years. At some point after the pie update it would stutter while scrolling or during animations intermittently. Even a factory reset didn't fix it. The phone was still fast but it was aesthetically annoying seeing the stuttering.
I drown the phone in the ocean on vacation this month and had to replace it so I got a used s8. I haven't had the same issue with scrolling but I've only had it for a couple weeks so far on a fresh wipe. It had some "normal" Samsung lag that the OnePlus didn't have while opening apps and it doesn't keep nearly as much in memory (4gb vs 8 GB RAM). But I'm still thinking the problem may be with pie itself since people were complaining about stuttering on both Samsung and OnePlus phones.
Hopefully my s8 is not affected and it's only certain ones experience it.

Wow! It's sad to hear an 8gb phone would still have the same issue. I wonder if this has to do with power management. Perhaps it's squeezing a tiny percentage of battery life out of saving some frames. It drives me crazy and gives me a headache. I wish they'd provide a simple switch for whatever this is.
This os feels like they ventured into breaking what works in an endless quest to fix what wasn't broken. Perhaps some team of programmers is celebrating minute improvements, but it's coming at the expense of the consumer, who never signed up to be the guinea pig. Each update seems to remove or break basic reliability and functionality that we paid for. I feel like I paid a premium price to become a software tester.
So reboots don't seem to fix the lag I'm experiencing when opening and closing certain apps. This phone was plenty fast before for me. Other issues are present now too. Auto adaptive display brightness doesn't work as well. I also really think it's sheet that you can't disable GPS and have the battery saving mode anymore! WTF Samsung.
