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..

ju@ncho.com · Apr 12, 2020

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.

peron · Apr 27, 2020

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

Frau Son · Jul 14, 2020

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.
