Interesting battery life difference in Tab S 10.5 WiFi and Tab S 10.5 Verizon - Galaxy Tab S Q&A, Help & Troubleshooting

I've been using a Tab S 10.5 Wifi for a couple of weeks. It's set up with all of my apps and tools, but is stock. Overall, I've been fairly pleased with it, but the performance was quite stuttery, and the battery life was painful. I don't have stats with me, but I almost always had power and battery concerns with it.
Today, I picked up an Tab S 10.5 LTE from Verizon and set it up the same way as the WiFi. I've only been able to work with it for a few hours so far, but the performance difference is quite noticeably better, and the battery life so far seems *way* better than the WiFi.
I'll try to keep an eye on it - I just thought it could be useful information for someone.

Most likely because the US carrier LTE versions (T807) run with Snapdragon vs Exynos (T805), and TW for whatever reason runs much, much smoother on Snapdragon. I've been getting great performance and battery from my Sprint LTE version so far.

Definitely a big difference

I went and tried out the Wifi Exynos (T-805) version at my local Tigerdirect store and then the LTE Snapdragon 800 version (T807) at Sprint store. I turned on the developer's mode in both and turned on the GPU utilization monitoring in the Monitoring section of the developer's mode. Here is my impression:
1. The T807 definitely is a lot smoother than the T805 when browsing through the TW. I would say it's about 30% smoother.
2. The graphic monitoring tool shows a lot more clippings in T805 than T807. As matter of fact, every time I scroll through the MX UI page by page, the T805 GPU clips a lot more than the T807, resulting in quite a bit of stuttering.
3. I didn't compare the video playback that closely but the T807 seems to be quite smooth and I didn't notice much of a frame skips.
I believe that TW is optimized for Snapdragon chip but not so for the Exynos. Also the GPU in the Snapdragon 800 is better than the one in Exynos. This makes the T807 a lot more usable than the T805. It actually is quite good. However, it is still not as smooth as the ipad air 2 I tried out in the Sprint store. That's especially true in the web browser. Apple's browser is a quite a bit smoother and faster from what I can tell. But the Tab S screen is certainly better than the iPad air 2 by a good margin. I am a bit disappointed at Tab S screen 's grey scale in the deep black region. It lacks some grey details when in the dark grey to black transitional region.

The SM-T807x variants have a different CPU, as mentioned above, Snapdragon 800 on the T807 vs Exynos 5 Octa 5420 on the T805 with the 5433 on T805S/K/L.
The Snapdragon is usually the choice for Samsung's top tier LTE devices in the USA (both phones and tablets it seems).
I picked up the T-mobile Tab S (SM-T807T) and am loving it, but holy **** it's expensive (practically $700).
Wish there was some development for it, but I won't hold my breath.

[Q] LTE vs Wifi

Are there any comparison reviews between LTE and Wifi versions of Note 10.1 2014 edition to be found somewhere? I'd like to see some good benchmarks and also hear about the lag difference between the two models.

As far as I know there are no direct comparisons of the two units, simply because they are as good as identical,save for the SoC ( CPU + GPU)
Wifi = the Exynos 5420 Octa core
LTE = Snapdragon 800
Performance wise there are some tiny differences, in short the snapdragon is a faster GPU while the Exynos a slightly faster CPU
In reality the differences are marginal
When it comes to lag, the problem seems to be software related and not so much hardware related. I've tested both , and a personal opinion is that the snapdragon is a tad faster in menu browsing etc,
I personally own the LTE version , well I needed LTE
Note the difference in Soc is more noticable when it comes to the mod and development community. Mods come out quicker on the snapdrag, simply becouse it has much broader support in the comunity, while Exynos is more locked and found primarily on Samsung devices
You can search around the forum for snapdragon vs Exynos questions , or google it for that mater, tons of threads etc with benchmarks and so on
You can also go here http://blog.gsmarena.com/samsung-galaxy-note-3-exynos-version-benchmark-results-are-in/ and check out their comparison between the two models of the Note 3 ( in essence a note 10.1 in smaller scale) . it's primarely a benchmark overview but it will give you a clue on the synthetic performance numbers.
Ok, thanks for the reply. Even though the performance possibly is not very far between the two processors, kind of stupid of Samsung to release two tablets with completely different hardware under the same name.
To add, its possible that the LTE version will see more Dev activity, mainly because of its similarity to the Note 3 LTE models worldwide. Until recently, the LTE version had a root method that didn't trip the Knox modifier that voids warranty. It was taken off temporarily as the latest software update for the LTE model appears to have some changes. The Exynos model cannot be rooted without tripping the Knox fuse at the moment.

[Q] Note 8.0 S Note runs much smoother than 10.1 2014?

Hi all,
I purchased a Note 8.0 for college at the beginning of the year. I really liked it. My dad wanted a tablet for Christmas this year so my family decided to get him the Note 10.1 2014 WiFi edition based on research and my experience. Once he got it open and started playing with it I noticed that my 8.0 appears to run much more smoothly than his brand new 10.1. The lag is most noticeable in the S Note app, or really anything that requires drawing or writing (he loves to play draw something 2 with us.) It is also noticeable when swiping through the home screens.
I ran the AnTuTu benchmark to make sure his was running as fast as it should compared to mine. He scored ~34000 and my 8.0 got a little over 20000. Those results were about what I expected.
Do you guys think his device is messed up or is this normal for the 10. 1 2014? I am pretty sure we can get a replacement if it isn't working correctly. I just did not expect a much faster device to run (what appears to be) is slower in any way.
Thanks for the input

Unfortunately that's normal. I find the 10.1 with much more lag than my N3 (which is very smooth)
I've learned to live with it, as long as the apps don't run poorly--which they don't.
There are a lot of threads on the 'lag' issue you're seeing.
I have both devices, my note 8 is running 4.2.2 stock and is a wifi only model with 16gb internal memory. My Note 10.1 2014 is an LTE model with 32gb, running 4.3 stock.
And i must say, fortunately (or unfortunately), it seems to me that's not a hardware issue. My note 8 flies, it's butter smooth compared to the Note 10.1 2014. I think Samsung screwed up badly with touchwiz.
For me the software driving the Note 8 feels much more light and mature compared to the Note 10.1 2014. Transitions, scrolling, swipes, everything feels snappier.
Bought the Note 10.1 2014 thinking this device would be a beast. And on paper it is. With the benchmarks too. But with real world usage The Good "old" Note 8 delivers a better experience.
The 10.1 2014 is so heavily bloated, with all sort of DRM, and unnecessary services running (knox?) in the background that the experience could be so much better.
I bought the p605M (here in Brazil) and here where I live, the official updates takes so much longer to roll out. But I hope when eventually 4.4 or even an new 4.3 version comes out, the performance will be improved. Read here in the forums that newer 4.3 roms resolved some lags and the wake up problem.
Would love to find a ROM compatible with my specific version p605M, I would root right away. But I'm afraid to screw up. For sure is not compatible with 605 roms.
2 to 3 seconds wake up lag? That's a joke. Samsung.

Yeah, that's true. But it has theoretically a better processor to handle all the pixels. Hope with software implementations they fix the performance.

But your All forgetting you can root, delete bloatware, freeze touchwiz home and have nova launcher, then compare it to the 8.0, head and shoulders above

its not as snappy as my xperia z ultra but i barely notice the lag, i didnt root just turned off/ disabled a few samsung bloat and used nova launcher. the one thing that bothers me is that there is no way to hide the notification bar while browsing the web nova lets u hide it in the home screen.

GMD let's you but have to be rooted you also get loads of shortcuts to play with my using touch gestures.
There are four things at play that affect graphics performance:
Display area. You're comparing devices with 5.7" (N3), 8" (N8), and 10.1" (N10.1-14) displays. All things being equal h/w has to work harder to fill and refresh a larger display area.
PPI. The N8 has a woeful 189 PPI. The N10.1-14 has 299 PPI and the N3 has 388 PPI. The pixels-per-inch combined with size of the display area determine the load the SoC has to carry.
H/W. The N3 and N10.1-14 have identical h/w. Filling a 388 PPI 5.7" display is far less of a burden on the SoC than filling a 10.1" 299 PPI display. So of course the N3 will have less lag and appear "smoother." If you "pinch zoom" on the home screen of the N3 to display multiple home pages it's almost instant. Not so much with the N10.1-14. As for the N8, 189 PPI on an 8" display is obviously less of a burden on Exynos 4412/Mali 400 than 299 PPI on a 10.1" display is for Exynos 5420/Mali-T626.
S/W. I can't help but feel the N10.1-14 was rushed to market. It certainly doesn't feel as "finished" and the s/w integrated as well as the N3. I had one of the first N10.1-12's sold. It took a couple of updates including the "Premium Suite" addition a couple of months after launch for it to feel "finished." Hopefully with future updates Samsung can better tune graphics performance to make the N10.1-14 feel more fluid.
The best analogy is BMW using the same 6 cylinder engine in the 3, 5, and 7 series. The 3-series will perform much better and feel more nimble because there's less mass to haul around. The N3 is a 3-series and the N10.1-14 is a 7-series in terms of "bulk." As for the N8, it's a 3-series with a 4 cylinder but less bulk makes it feel more nimble than a 7-series with a 6.
The display, at least to me, is one of the most outstanding features of the N10.1-14 and the biggest reason I moved to it from the N10.1-12. If the consequence is the occasional millisecond long stutter in a transition, so be it. And OP, make sure your father's N10.1-14 has all the updates (I think there have been two in the U.S.). I have no lag or delays in the specific applications you mentioned. In fact, I've noticed no lag or stuttering when working in a single specific application; only occasionally in transitions or sharing data across apps.

Note 7 Snapdragon vs Exynos

I have always used smartphones with a Snapdragon in them and been waiting a long time for a decent Note to come out to upgrade my S4. I have heard a mixed bag in regards to Snapdragon and Exynos from various review sites and reading peoples comment. Some say SD820 runs hot during gaming, some say Exynos throttles a lot during gaming while others say the SD produce better sound and the Exynos is not optimized well.
So I thought the best place to find out for sure is from XDA. To set the scene, I mainly be using the Note 7 for music, gaming and watching anime. Performance and battery life is the main things I am looking for, anyone able to comment on personal experience with the variant they have or really know your stuff in regards to the variants, would be much appreciated.

I just ordered the Exynos version and should be getting it soon. I've gone through 4 SD 820 versions on AT&T USA and can confidently say based on my experience, the performance is abominable. It goes from being insanely faste to incredibly laggy in everything you do. The battery life of all 4 phones have been unimpressive. I pretty much have to charge about twice to get me through the day.
The loudness is just okay. I'm looking forward to comparing with the Exynos version when it arrives. As for the 4th SD version Note 7 I'm currently using, it will be going back back to it's maker really soon.

Thanks for this, I would be interested to know your impressions on the Exynos variant of the Note 7 once you have gave it a good run.
Looks like there is a clear winner here. Thank you for everyone who voted in the poll. I really appreciate it.
I've heard nothing but bad stuff about the Snapdragon version, hopefully nothing an update can fix.
Thank you for making this poll. I am seriously thinking of returning the Galaxy Note 7 I purchased in Canada in favour of a Galaxy S7 Edge. Overall performance, operating temperature and battery life are more important to me than a minor boost in rendering performance.
My Canadian Snapdragon version has been great. No battery life or heat issues here. It took a few days to settle in after I set it up, but it's been great since. Battery life is slightly lower than my S7 Edge was, but the battery is also slightly smaller. I'm averaging 5.5-6hrs of SoT (auto brightness + location on), which is good enough for me.
The Exynos versions seem to be self destructing randomly after a few days. Bricks and bootloops.
Thanks
Thanks for the post and all the votes guys. I was also thinking about this and according to android central, strictly based on numbers, the exynos version has a better cpu and the snapdragon version has better gpu. However this doesn't really say anything about real world performance.
I have both for this week...I bought Tmobile on preorder and just bought Exynos as well...I love the Exynos...does come with a funky plug for the wall...it was warmer too as first...Did the update lastnight and its super fast and not warm anymore...I bought because of Unlocked Bootloader and possible Root soon...Chainfire does not have his device yet...so soon it will be up hopefully...out of the 2 the Exynos is brighter as well when both are maxed. My only con and I think its fixable is I got the FD Duos..and Messages has a blue #1 on it...All my messages do for that matter and the send button had it...trying to figure out how to turn it off... it's just my phone letting me know what SIMs card I'm using but I don't like it. But out of the two I'm definitely happier with the Exynos

Refund Snapdragon For Exynos?

My carrier (Bell in Canada) has agreed to let me do a refund on my Snapdragon Note 7 because of the recall. I was thinking of then going and buying a Exynos version because I get lag with my Snapdragon version which drives me nuts. I was looking into B&H Photo because they provide a 1 year warranty and say they will be getting new stock of the "f" model around Sept 18 that is safe from the recall. I would end up paying about $500 extra to switch versions and be contract free. Is it worth it? Is rooting and performance that much better?

Yes, the Exynos is much smoother in real life. The SD is a bit of a fail in the Note 7.

I agree get the Exynos if you can. The Snapdragon is full of problems and terrible battery life compared to the Exynos version.
Literally the only way I can make my Exynos lag is too open all 120 apps while multi windows + running Antutu (exaggeration obviously) in all seriousness I have never seen my device lag even when gaming order and chaos 2, dead trigger 2, Pokemon Go, clash of clans..etc

I talked to them today over chat support. I asked about exchange or refund. They seemed reluctant at first but said were gonna put a note in my account for when I went back to the store I got it from... Saying to refund it. No if they actually do so at the store or what trouble they give me is another thing.
So here is my story...
I bought the Note 7 in Hong Kong (SMN-9300). Normally in HK all previous note / galaxy releases have always come with the Exynos chipset. So to my surprise when i picked up my brand new Note 7 on September 2nd, It had the SD 820. After reading hundreds of posts on here and other forums and seeing lots of users claim the Exynos was better I went and bought a Singapore Version SMN-930F which comes with an Exynos CPU. After 2 days of using both I can honestly say there is LITTLE to no difference in real life everyday use.
I had let my obsession get the best of me and shelled out the money to buy a second Note 7 just because everyone was saying "Get the exynos" "Its soooo much better". This is total B.S. Im holding both devices right now and I can promise you there is NO huge noticeable difference. Ive heard reports of lags on both the Exynos and Snapdragon version. But both devices which i have run smooth and fine. The battery life is almost identical, perhaps slightly better on the Exynos. But its hardly noticeable at all. I find that the SD has MUCH better GPU performance and does not run nearly as hot as the Exynos.
After obsessively benchmarking both, I've come to the conclusion that they are almost identical in most cases. The SD version always destroys the Exynos on the Antutu (Which is mostly to test GPU / Graphics). While the Exynos crushes the SD on geek Bench (More CPU geared). As for other tests like Basemark OSII, Vellamo PCMark etc they both score almost identically. To be honest I really don't think these benchmark results mean much and are not very relevant to the everyday user. Because despite the bench mark results, I find that the Exynos handles games / graphic intensive tasks just as well as the SnapDragon 820. And the SD runs as fast, and is just as responsive as the Exynos.
The moral of the story is don't over think things like i did! Save your $500 bucks and stick with the SD version. After using both devices for a few days i can tell you from HONEST experience there is no noticeable difference between the 2. They are both totally capable of runnings apps, web browsing, watching movies, playing games and things that most users need. If there was a HUGE difference between the 2 I would tell you go ahead and spend the $500. But in all honesty you will be disappointed when you shell out the $500 bucks and get the Exynos and notice there is little to no noticeable difference.
In you initial post, you stated that your SD version is laggy, and thats why you want to exchange to the Exynos version. But take a look at some of the SM-930F (Exynos) posts on XDA and you will see users facing the same problems with the Exynos version. From lagged typing / keyboards, Boot Loops, Screen issues to over all lagged performance. Yet as mentioned I have two Note 7's (SD & Exynos) and have not had any of the above mentioned problems on either. I suspect the problem could be related to the early produced models, Battery issues, or software issues. Have you tried to factory reset your note? Make sure it has the latest software update and try it then?
Also keep in mind both devices are still reasonably new. And with the whole exploding battery fiasco, Samsung probably has not had much time to focus on software updates. Im sure after the Battery / recall issues are resolved and the device has been on the market for a few months both versions will get several updates which will make them even better.
Hope this helps!

I find that the SD has MUCH better GPU performance and does not run nearly as hot as the Exynos.
After obsessively benchmarking both, I've come to the conclusion that they are almost identical in most cases. The SD version always destroys the Exynos on the Antutu (Which is mostly to test GPU / Graphics). While the Exynos crushes the SD on geek Bench (More CPU geared). As for other tests like Basemark OSII, Vellamo PCMark etc they both score almost identically. To be honest I really don't think these benchmark results mean much and are not very relevant to the everyday user. Because despite the bench mark results, I find that the Exynos handles games / graphic intensive tasks just as well as the SnapDragon 820. And the SD runs as fast, and is just as responsive as the Exynos.
The moral of the story is don't over think things like i did! Save your $500 bucks and stick with the SD version. After using both devices for a few days i can tell you from HONEST experience there is no noticeable difference between the 2. They are both totally capable of runnings apps, web browsing, watching movies, playing games and things that most users need. If there was a HUGE difference between the 2 I would tell you go ahead and spend the $500. But in all honesty you will be disappointed when you shell out the $500 bucks and get the Exynos and notice there is little to no noticeable difference.
In you initial post, you stated that your SD version is laggy, and thats why you want to exchange to the Exynos version. But take a look at some of the SM-930F (Exynos) posts on XDA and you will see users facing the same problems with the Exynos version. From lagged typing / keyboards, Boot Loops, Screen issues to over all lagged performance. Yet as mentioned I have two Note 7's (SD & Exynos) and have not had any of the above mentioned problems on either. I suspect the problem could be related to the early produced models, Battery issues, or software issues. Have you tried to factory reset your note? Make sure it has the latest software update and try it then?
Also keep in mind both devices are still reasonably new. And with the whole exploding battery fiasco, Samsung probably has not had much time to focus on software updates. Im sure after the Battery / recall issues are resolved and the device has been on the market for a few months both versions will get several updates which will make them even better.
Hope this helps!

I think you're missing the biggest advantage of the Exynos variant. A lot of users love it for its superior battery life, and having used yours for little time, you probably wouldnt have had enough time to thoroughly test it. Correct me if im wrong!!
I would happily dish out $500 for a Note 7 that lasts 2 extra hours of the screen on, especially with less lag. I can personally confirm the SD Note 7 is trash.
the only issue I'm having with the exynos is button lag (have to keep pressing the button esp on the phone app before it works) and occasional reboots. It also hung when sending a SMS whilst listening to music, taking 2 restarts to go back to normal.

Ive been using both phones (Exynos & Snapdragon) for a few days now. Again im using the INTERNATIONAL version of the SD (SM-N9300). This model was only released on September 2nd, so maybe its better than the US snapdragon version released almost a month before. Meaning maybe samsung has made some changes / tweaks to the phone to make it run better.
- Lag : When comparing the 2 I see little to NO lag in either phone. And to be honest when I do see the occasional bit of lag its on the Exynos version! This normally happens when typing . I have yet to experience lag on the SD version.
- Battery life : I Can confirm that there is NO where near a 2 hour advantage. I have left both phones on next to each other for 2-3 hours strait and the difference in battery drop has been max 3-5%( So for example the SD would be at 85% and the Exynos would be at 88%).
And if you are advising him to "happily dish out $500 for 2 hours battery life" That sounds a bit silly. For $500 bucks you could go buy yourself a whole second phone like the OnePlus 3. Which would give you a lot more for your money.
Hell for $500 bucks you could grab a brand new OnePlus 3 + External portable charger + order a pizza!
Also as mentioned I'm almost certain the difference in battery life is no where near 2 hours. More like an extra 15-30 minutes at MOST. I will post more accurate details after testing the phones further in the coming days.
As of now the ONLY advantage I'm seeing with the Exynos is the ability to root it now. And that is presuming that you are willing to VOID the warranty on a brand new $800-900 phone you just bought. Im sure down the line the SD version will be rooted. And with everything available today (App De-enabler, Helium, etc) rooting is not much of a priority for most as it used to be. I would honestly be hesitant to root my Exynos version being that its a expensive devise and still very new. I don't want to risk voiding my warranty just yet.
So in short:
BOTH VERSIONS - Little to no lag, Perform fine.
Exynos - Slightly better battery (3-5% overall is my estimate), ability to root NOW, if you are willing to void your warranty.
SnapDragon (SM-N9300 International version) - Slightly better GPU processing. Does not get as hot when running heavy / graphic intensive games. No lag issues with keyboard. No crashes / boot loops yet.

So you don't experience the issue with the Snapdragon where the phone will be super fast like 90 percent of the time and then just gets super leggy and slow... So that for example if you're typing you have to wait for it to catch up... Typing one letter at a time? That's what happens to mine... 90 percent fast. .. 5 percent slow and 5 percent unbearablly slow. It doesn't seem to have any pattern or reason... Every with very little open it will start to stutter like that.

Nope.
I have been using the SM-N9300 (Hong Kong version) of the Note 7 w/ the Snap Dragon 820 for 6 days now. Have not had a single lag issue. No problems whatsoever with the typing. I have installed and used the stock Samsung, Google and Swift Key keyboards and all of them work perfectly fine with no lag whatsoever.
What is funny is that the Exynos version I recently purchased and have had for almost 3 days now, has had that lag with typing. But only once or twice and nothing too extreme. There is actually a whole thread of people using the Exynos version who are experiencing the Key board lag issue here: http://forum.xda-developers.com/note-7/how-to/galaxy-note-7-singapore-thread-sm-t3444909
and
here: http://forum.xda-developers.com/note-7/help/note-7-repeated-restart-bootloop-issues-t3444510/page11
Snapdragon = locked bootloader.
Exynos= unlocked.
That's all that needs to be said and should be an easy choice if your here on XDA.
sent from my Note 7 or S6
Might be blasphemy here but after years of custom ROMs on S3 and shortly on S5 (which made the experiences great, no doubt), I can't think of any reason to need root with what I can do on the Note 7 as it is. Even Good Lock takes me back to that nice notification and quick settings I was used to. Of course that's just my requirements of the phone, no doubt plenty want root.

Overall speed

Would you say that the Samsung Galaxy A51 is "fast" in day-to-day use? A higher rating indicates that you think the Samsung Galaxy A51 exhibits fantastic performance. Like, is it as fast as your tears when you watch The Titanic?
Then, drop a comment if you have anything to add!
I'm currently using Samsung Galaxy A51 with Feb 2020 Patch, performance is very sluggish and slow compared to other 6gb ram devices that I used last year, you can "Feel" the delay of animation from fingerprint, opening, and closing apps, I am totally disappointed with the performance of this device, hopefully Samsung can find a way to optimize its software with its hardware capability.
It's a little all over the place for me, but ultimately disappointing. I don't know if it's a problem with my device, but it seems like my phone just ****s the bed during random intervals. There are times when I'll be using my phone and it will be surprisingly smooth considering the hardware, and other times where the animations feel very choppy and unpleasant. I've been running a lot of AnTuTu benchmarks, and I've got scores up to 180,000 when it's doing good, and down to almost 130,000 when ****s going on. And that's not just AnTuTu, these are differences I can feel in normal operations. So it's weird. I'm not sure if it's some kind of hardware bug or I've got some background process eating away performance that I'm unaware of, or something else. It's a real shame, because there's a lot I love about this phone.
But that's my experience. For the record, I have the Latin American variant with 4gb of ram. I still have yet to get any updates on it. It seems I'm stuck with the December security patch (I'm not sure what's up with that).

Think I am having a similar experience, much choppier then I would have expected. Hangs a lot when opening or switching apps. Battery life disappointing as well. I am also on December security patch.
Takes a second for home screen to refresh and load folders etc when going from an app to the home screen, not ideal.
Slow performance
Samsung A51 became slower after the new updates..
Good my variant is the SM-A515F (Panama), I am in with the firmware A515FXXU3ATC5 with security 2020-03-13. It is super fast and very stable, it does not have to be root, just apply disinfestation of garbage apk, through the ADB method, and the phone has shown very good behavior, getting 34 to 36 hours of battery, and in games this Super fast. I recommend you to update your official bases and remove garbage apk, with the ADB method.

Hello,
Good.
What is the packages to uninstal ?
Thanks you
I wanted to chime in here. I just got this device via Sprint so US model not the international one. I was a bit fearful coming from a pixel 4 based on the performance comments. I like plastic phones that have good specs and can be replaced if I drop it and crack the screen (refuse to use cases).
My experience with performance has been pleasantly surprising. Is it as fast as my pixel 4 was, heck no but for day to day use do i really notice enough that makes me regret the switch? Nope, not one bit. Most are probably aware but there is a good YouTube guide to speed this device up. A lot of it is common knowledge via Developer options but some of the other tips are good ones to apply if you aren't familiar with Samsung phones specifically.
How to enable Beast Mode on Galaxy A51: https://www.youtube.com/watch?v=HJ0Lkax0QSs&t=331s
Now if we can get a good ADB bloatware removal guide for this device we should see even further improvements.
Using the debloat guide for the A50 works just fine. The phone looks and works great for me and it's the 4GB version. Fingerprint unlock also works reasonably well and reliably after applying the tips listed on these pages.
It's pretty bad, yeah. My Nokia 7 Plus is faster and a better phone.
Seconded, trick is to remove all the bloatware

I'll second this. Once I removed all of the bloatware (or technically, disabled, via the well known ADB method) and changed launchers (Lawnchair), this device runs like a dream. Hell, Asphalt plays w/o issue and is smooth and fast.
My only gripe so far is that I have been unable to find a working Gcam, the camera software leaves much to be desired.

Hello,
I desabled some apk.
Do you have a list of the apk you desabled ?
Thanks
Why is turning the screen horizontally or vertically so slow? I've never had a phone where it takes 3 seconds for the screen to rotate after I turn my phone until a51.

I was considering a galaxy a51 as replacement for my nokia 7 plus, because of its infamous hardware issue are starting to bother me (display brightness, loose usb port).
I take it from your comment this phone isn't a good replacement
had it for a little over a week now, not a heavy user but moderate (mostly taking photos or using social media).
It's not bad, ofc it can't be compared to a flagship, but for simple daily tasks it's more than enough at this point
opening the camera takes quite long sometimes and apps tend to take a second or two to start, but then they're pretty fast and snappy
paid 280 € for it and that seems absolutely reasonable to me

The cure for lag is simple, I've used it on every Samsung device since the S2:
Uninstall or disable all the bloatware you can. Install another launcher (I use Nova) - set all animations to the fastest.
For good measure, disable all animations in settings -> developer options.
Lag gone.
CAVEAT I don't do gaming (life is too short) so can't comment on that.

Probably due the low end processor Samsung put on it, sadly it has its limits
I've setup several A51's for people and it is hands down the slowest budget phone I've used in awhile. If you have Verizon, I strongly recommend the A51 5G UW or the S20 FE instead. The Snapdragon 765G and 865 are much faster and seem more stable. Given that the 5G models are also affordable, I cannot recommend the regular A51 to anyone.

Yes, perhaps. But...My wife and I both have the A51 and I have recommended it to my brother. He and his wife now have the A51. None of the 4 of us play games, and we all are between 70 and 80 years old. For us, it's the best phone we've ever had and I sold my S8 to buy the A51. At my age, the S8 was just too small and had a good but limited Camera. The A51 is perfect for all our needs.
It's a great phone for the $279 we each paid IF you don't do any heavy gaming. It's plenty fast enough for us old folks.
