Samsung Galaxy A21 issues - Android Q&A, Help & Troubleshooting

Good Day,
I have a Galaxy A21 running Android OS 12 and One UI Home 4.0, it has a TracFone logo on the start and its already unlocked. I'm having some issues with the fingerprint reader and with the phone saving my passwords, patterns and biometrics. I think bringing it back to version 11 or 10 will solve the issue. But I've never reflashed an Android device and it didnt get bricked, I was good with Motorolas and nokias but since these came out, I didn't have much practice.

Did you upgrade to 12?
If so did you do a factory reset?
At least clear the system cache.
Rule #1- if a OS is fast, stable and fulfilling its mission let it be!!! Upgrades and updates can and do break Samsung's.

I did a factory reset
All caches are cleared
Samsung wasn't a phone builder from sunrise and at sunset, they're still struggling. These are just businessmen or women making the cheapest, cutest phones possible. These batteries were made over 5 years ago so the device has little or no battery life and a whole host of other complaints from espionage to unlawful conduct. Android is fine, samsung is crap!
I actually purchased the phone with the Android OS 12. but I know it's just the One UI 4.0 not mapping onto the android OS as it should. I've been trying to unlock the boot-loader, trying to root, and downgrade to A OS 10 or even 11 to get it running stable.
Besides that, something weird happened. I got frustrated with the phone and put it in the case backward. It pressed all three buttons and the phone did this in the pic. It entered a mode requesting a Custom OS.
My final plan for this device is RiceDroid or another custom OS.

The Li batteries are days or months old when assembled into the phone. They have a finite storage life because of self discharge. They are never fully charged before being shipped as it would degrade them faster during storage. A 70% or so charge is typical.

I have two stock N10+'s Snaps that were bought new. Both still running on the original firmware Pie and Q. The oldest in my hand is over 3 yo with well over 8k hours on it. It looks, feels and runs like new, zero display degradation. Only repair is a battery replacement. Last factory reset was over 2.5 years ago, it still running fast and stable. Samsung is capable of making high quality flagships if they want to. In my opinion the N10+ was the last great one they made; Samsung's zenith. Samsung's been dropping balls now for 3+ years. They've abandoned their loyal power user base completely.
One reason you buy a Samsung is for the UI. A custom rom will cause you to lose a slew of features and have numerous new issues. Android 12 is a known to be a mess. 13 doesn't impress me either. Google is trashing Android Apple bad. Now Samsung started following their lead by removing expandable storage.
Snapdragon's are notoriously hard or impossible to root so you may be stuck with 12. If so the bootloader version determines if you can roll it back. Most times the bootloader anti rollback prevents this. Those who upgraded to 12 from 11 can generally roll it back to 11. I doubt this is true with a new Samsung that was factory loaded with 12.
Call Samsung tech support and share the wuv, I do. If you do speak with them ream them out for no expandable storage as well as their other ongoing blunders. If I was in your position I be real pissed too...

oh man, this one is serious. I got gypped. Big time, $33k JMD for a phone that wasn't even $130 USD online.
But there is a route there to download a custom OS that I posted in the picture i think that's built into the bootloader, I dont know of samsung running/building custom roms for Galaxy A21 I'm still trying to unlock the BL, root it, TWRP it and RiceDroid. Maybe I'll have to bring it to a tech to at least unlock the BL and Root it, I can handle the TWRP and RiceDroid.
I almost forgot to mention; I got to a good level in the BL unlocking but when I adb it. It brought the phone to a screen that said entering fastboot and it got stuck there and I had to restart the phone.

To close this out:
I got frustrated and sold the phone and got a Nokia C1 Plus that works fine.
Blessings

G3 How Much Life Left

Just a generic question on how much time and what model you going to next. It appears with the stock ROMS on Verizon, most devs have moved on. The HTC 10 Verizon has Sunshine now at least, don't know jack about a new Nexus model. Just curious as what you guys are moving to. Thanks

At this time, I'm sticking with the G3 unless there is a reason to upgrade. I've had the phone for 18 months now and I must say, it has been the absolute best phone I've ever had. Currently, I'm running stock, unrooted Marshmallow and it runs great for me. I haven't needed a reason to root. Root was mainly for Titanium Backup, but the LG Backup tool does just what I need if I ever need to reset the phone or want to try a new ROM.
Greenify runs as well, albeit not automatically, but I made it so that I can just press and hold the "home" button and it launches Greenify before locking the screen and shutting the screen off. Battery life is excellent for me. I can get through the day without having to charge (unless I decide it's time to play a game and then, all bets are off but that's going to be the same for just about any phone).
However, my oldest daughter just upgraded from her iPhone 5s to a Samsung Galaxy S7 and she is absolutely satisfied with it. She became tired of Apple and how difficult it was to copy music, files, etc back and forth without having to use iTunes. Battery life for her is excellent as well and she loves the fact that she can add an SD card to it to store pictures and music. She has a 64gb card in it.
So, if I were to upgrade, I would probably look at the S7 (non-edge) or maybe the LG G5. But, as I said, my phone still runs as good as it did when I first got it in December of 2014, so I have no reason to upgrade.
What would really force me to upgrade eventually would be if another major exploit was found for the version of Marshmallow that won't get patched by LG/Verizon. Then, I would probably upgrade.

What are the chances the LGV20 purchased from ebay can be hacked.

Hello folks, my LG V20 from verizon has been screen damaged a lot and this time, I decided to buy from ebay at a fraction of price. This question is not specifically for LG V20 but I just decided to put here since this is the phone I purchased. It arrived and looks nice and I dont need all the bells and whistles that came with original carrier however there is a concern whether the phone's software or hardware has been tampered with. I know it requires a specialized a deep knowledge and extremely unlikely that ebay buyers would do these but I'd take no chances whether there is a slim. That is because, understandably, all your personal information, or simply put, all your lifes including passwords, financial information and almost everything account you can think of can be accessed throug your phone. Has there been any proven or unproven instances of hacking through phone sold on ebay in the past?

To answer your question, yes. If the phone has been rooted and the data was reformatted ex. Twrp and, wipe system, data, and both caches then all data should be gone.
Looks like I need to do homework. I did some light bag
Looks like i need to do some homework. I used to do some light hacking activity I.e. burning custom rom etc when i had Samsung, but that was long ago. It appears to be unlocked for any carrier and i just installed SIM and did couple of OTA update from Verizon. I am not sure if I should get started by whether it is rooted and any custom rom installed. It looks perfectly ok but certainly feels sluggish than brand new phone out of box from carrier.

i95swervin has posted today that he will upload a rom for your phone tomorrow. I'm running the alpha rom on the H918 V20, 1.0.7 release and, it's been stable and smooth. I tweaked the kernel alittle and, made it exactly the my liking, check out this thread when you get a chance https://forum.xda-developers.com/v2...ega-rom-oreo-vs995-h910-ls997-t3847510/page37

what you mean??
If you suspect the rom has been tampered, its better to reflashed the rom.
About as much a chance as you have at being struck by lightning and getting super powers.
If you want to concern yourself with the what if nefarious black hat did this you should not buy used. But a factroy reset and or twrp reset will blow out any cobwebs they could put on it.
In theory about the only thing they can do is report it stolen on you since your phone is not tied to your carrier your sim is. So unlike the phones of yesterday where they had no sim and the phone had it built in they would need your sim to clone your phone.
I bought from ebay too. At first there was a little bit of a white line 2cms up and 2cms down the display mostly unvisible. This sounds weird but when I unlocked the bootloader with dirty santa it appeared as a full black line then it came back to normal. 2 weeks later it comes and goes but now it seems this black line is permanent, it would only be white if the background is black.
The seller has extremely positive reviews btw and it was brand new with warranty. Inside the phone everything seems fine. But I'd charge the phone and it would stay at a 100% for an hour sometimes before dropping to 99%

Question New G Play Owner with questions

Hey everybody. Just getting my new 2021 G Play up and running. For some reason, it seems slow as hell. Specs wise, it should be significantly faster than it is. I'm experiencing delays when typing, changing apps, and just the lag time from when you click a button until the screen changes and you can go onto the next task sucks.
Anybody have any tips? What might be causing the issue? I got the 3 gig RAM version, which should still be plenty. I feel like it's being artificially slowed by software and it would be nice to fix that problem.

do a factory reset; then unlock your bootloader; then flash the retail US rom (retus) ; then root it with magisk; then de crapify til your heart is content...
or at the very least factory reset, and uninstall facebook

I don't have facebook or anything else thats a big resource hog.
I bought mine unlocked directly from Motorola a few weeks ago, I assume it should have the retail US rom?

Yep, it's the retail rom. I am in the exact same boat as you, bought it a few weeks ago from Target US since I needed a decent unlocked phone to use with a high data prepaid sim. So far this thing is the best phone I've ever had. I'll share a few things I've learned/done since I've unlocked and rooted mine if you would like.
My device was reasonably quick out of the box and I noticed little if any lag. But I usually buy 50 dollar phones from walmart so I might not have the most reliable opinion about that. By the way the Facebook APK and a few facebook services reside on the phone, and I can't recall but they might even be installed out of the box but just deactivated. You'd be surprised how much crap is on this thing that sits idly by waiting for a compatible carrier SIM to give the phone the Go-Ahead to install.
So yeah, the tip I would suggest is to unlock the bootloader, install magisk and get root, then use some magisk modules and ADB scripts to start cleaning out the stuff you don't want. You'll be glad you did. I stripped out a lot of verizon installed services, amazon/facebook APKs, and all the motorola OEM apps I wasn't interested in, which was basically all of them. The phone is butter smooth. I have cloudflare DNS and ad aware installed, in addition to a couple of other modules.
I used to root devices years ago and took a break from around 2015 till now. Magisk is a slightly different experience than the way it used to be but for the most part it's dead simple and very flexible. On top of that, with the right flash tools and a copy of your firmware these devices seem nearly unbrickable. I've already soft bricked the thing a couple of times and it was just a matter of a quick magisk reflash and finangling some settings. Kept the same OS install, didn't lose anything.
Good luck! Let me know if you need any help.
Well this is good info, thanks. To be fair, this is about the slowest phone I've ever had. I'm coming from a OnePlus 6 thats been a constant headache too for the past couple years (everytime I wanted to make an outbound call I had to reboot the POS). I picked up the OnePlus second hand. I just can't stomach these $1k phone prices, and this has nearly the same specs as most of the $500 phones.
yeah, for me it was getting rid of the facebook.apk that came packaged. As soon as I did that it was a new phone. Didn't even need to bother with magisk this go around.

Safe full backup - back to Android 10 help

Hi,
I, like many others, got forced onto Android 11. I have a lot of problems with it. With or without root. The most annoying of which is the wifi aggressively dropping/changing. Bluetooth failures. Volume drops that don't return to normal, forcing a reboot to fix. Clock and background/screen saver problems. System UI crashing. Keyboard freezing and lagging on certain sites with textareas. I used my phone without root for a couple days after the forced upgrade and all of these issues were present with or without magisk modules.
I'm interested in going back to Android 10 and blocking the a11 OTA in Hosts.
I'd like to get some help with a couple things. I'd like to make a FULL flashable backup of my current device as is. Just in case I mess something up, I can get back to this current state as worst case, very easily. Do I use the MSM tool and copy something? Do I boot twrp and push something over? Please advise the safe and smart way to get right back to a 1:1 of current install. I want to be very sure about this part.
After I know which way I can safely get back to current state, can I use the MSM tool to wipe and flash an older build of Android 10? Or is it a problem after being on 11 because of some restrictions (partitions, RO, twrp no mount) somewhere?
If I can get back to an older build of Android 10, I have a couple options (grayhat and httpcanary) to monitor the traffic to see what we need to block in Hosts for sure.
I'm open to other suggestions also. Someone in the root thread said they proactively tried to disable some services around update and it was still forced on them.
OnePlus 7T Pro 5G McLaren TMobile
Android 11.0.1.2HD61B
(Carrier unlocked, bootloader unlocked, magisk root)
Thanks for any help
Disable the T-mobile update app or ask them to disable it on their end, they can.
Backup all critical data by direct file transfer and verify... just in case.
There's no way to do a full nandroid backup, e.g. restoring things exactly back to how they are now. Best you can do is use the app Swift Backup to backup app data/settings along with Google's backup and OP's backup app.
As for OOS11, have you tried resetting back to stock (factory reset while running OOS11)? Chances are you just have some leftover things from OOS10 that didn't play well with the upgrade. So before you abandon OOS11, try that first (factory reset from stock recovery). Make sure you've copied any backups to your PC first. If the issues come back after restoring your backup from Swift Backup or from Google or OP, then you need to find out exactly what app(s) are causing issue or just start from scratch.
As for the MSM Tool, it will restore you back to OOS10 just fine on its own.
Lastly, the OTA updates are downloaded from https://android.googleapis.com
For example, the url for the latest OTA to go from latest version of OOS10 (10.0.43) to first version of OOS11 (11.0.1.2) was
https://android.googleapis.com/packages/ota-api/package/45ba72b0b2f7c643a09d2d0875459cd01b8db998.zip
I pulled that from the update log. So blocking
https://android.googleapis.com/packages/ota-api/*/
in AdBlock or other hosts file app should do the trick. It may still see an update available, but it will definitely continue to fail when trying to download it.
But try OOS11 clean (after a factory reset). I bet all your problems will go away. I have exact same phone, not a single issue on OOS11, bootloader unlocked, latest version of Magisk.

Thanks so much for the detailed reply.
My main reason for rooting my phone is to have full speed tethering. If that worked, I would try a reset. Since it doesn't, it's a good excuse to go back to 10 on its own for me.
No simple method for a full nandroid backup is going to slow me down. I need to go thru my apps and make sure I don't forget about anything important for a reset or a downgrade.
Do you have any hypothesis on why they forced Android 11 so hard?
During the time I wrote this message, my wifi switched networks a half dozen times. When this first started after the force to a11, I thought it was strange because I wasn't rooted and any modules shouldn't have been affecting anything. They're only added props (for the tethering module anyway). I don't have the Qualcomm crash others are reporting but maybe something in the new settings are related and causing both problems, theirs and mine.
Do you have multiple APs within reach of your phone? I've tried to disable/enable different connection options in the wifi settings and handoff settings. Nothing seems to help. It wants to drop me off my AP to any closer AP, constantly. Which is particularly annoying because I'm constantly in ssh sessions and that closes them. I can avoid that somewhat by forgetting the other APs near me so it tries to stay connected to just one but I shouldn't have to do that. I never had an issue before the update. In fact, I was actually really happy with how stable Android 10 was for our device.

Honestly I can't help. OOS11 made my phone even better than it ever has been. No exaggeration. And not a single bug or even issue. They probably saw the same results on their test phones and pushed it really hard because they knew people had been waiting a very long time for it.
That's why I really think you have some trash left behind from your OOS10 install that made the upgrade to OOS11 go crazy. Once you get your backups done, please try a factory reset on OOS11 and don't restore any Google or other backups and just see if you have any issues. It could all be due simply to needing a "fresh install"
Edit: As for high speed tethering, is that accomplished with a Magisk module? If so, it probably needs the tiniest change in directory names/path to be compatible with OOS11, just like the boot and shutdown animation modules
Edit2: And yes, my phone can see at least 15 APs while at home. Never have any trouble connecting via 802.11ac on 2.4 or 5ghz at home, and never had any trouble with other random hotspots.
You've got some OOS10 settings/junk/leftovers interfering with OOS11. Not trying to sound like an idiot TMobile tech, but in this case you do need to factory reset and I bet all issues go away.

I believe you. I don't think you sound like the robot techs either. Yes, it can be accomplished with a magisk module. Which I first tried to edit like the animation modules. When that was unsuccessful, I did it manually by creating/editing props. The tethering provision and dun props. I even tried them in combination with another apn using only ipv4.
Some other phones report the module still working in Android 11 so I was hopeful it was just a path adjustment or that manual would work. It's still likely it could be done but I have to balance how long someone with more experience to bring a solution might take, with how long I can get by with this 600kbps throttle. I have kids and having internet (capable of YouTube, 600kbps doesn't cut it, especially on multiple devices) available for long car rides is really helpful after they're tired of playing Eye-Spy

Post the Magisk module for high-speed tethering and I'll take a look at it. It'll either be really simple to get it working on OOS11...or not lol.
All credit to the authors and yadda yadda.
There's another one floating around.
In this one, I changed it to be /product/ but didn't have success.
If you do have success on a11 with it, that'd be cool. I can find out if a reset will clear up these other issues I have or not
Hello everyone, I'm in a similar situation though I was wondering if it might be a different problem.
So I bought a 7TPro Mclaren off Ebay and for the last year, it's worked fine. the phone came factory unlocked, with zero issues connecting to Telus (my Canadian provider). Last month my phone force-updated itself to android 11, and nothing but bad things have happened since. screen frame-rate tanks randomly, apps are slow, battery's tanked, the works.
After resetting the cache 3 or 4 times and still having issues, I reset the phone to factory, stock settings, but the phone still performs poorly Maybe because I re-added all my apps and pictures via Oneplus backup? either way, I'm very fed up with how the phone has been especially the battery, so I've been looking into downgrading back to Android 10, but it seems that the Tmobile variant has trouble doing that (i.e. no simple menu option).
Should I try downgrading to Android 10 again and not bothering with a backup? I don't have too much to lose as of right now so I don't mind resetting it again, but if restoring all my pictures via backup is what's causing the issue I'm willing to do that. Should I make another Oneplus backup before I do this, or should I back up the data to my PC first? I find it very irritating that T-mobile forced this update so I will try and block the upgrade in my hosts but I'm worried that won't work because I don't plan to root my phone and block the hosts files.
Any tips or help would be appreciated!

Hello everyone, I'm in a similar situation though I was wondering if it might be a different problem.
So I bought a 7TPro Mclaren off Ebay and for the last year, it's worked fine. the phone came factory unlocked, with zero issues connecting to Telus (my Canadian provider). Last month my phone force-updated itself to android 11, and nothing but bad things have happened since. screen frame-rate tanks randomly, apps are slow, battery's tanked, the works.
After resetting the cache 3 or 4 times and still having issues, I reset the phone to factory, stock settings, but the phone still performs poorly Maybe because I re-added all my apps and pictures via Oneplus backup? either way, I'm very fed up with how the phone has been especially the battery, so I've been looking into downgrading back to Android 10, but it seems that the Tmobile variant has trouble doing that (i.e. no simple menu option).
Should I try downgrading to Android 10 again and not bothering with a backup?

Sorry to hear that.
Do fresh installs for the apps.
Do direct file transfers to/from the PC for all other critical data. "Restore it all" apps can fail miserably and are hard to verify the data they supposedly stored.
11 is a mess but this might help... or not.

Try another factory reset on OOS11 but don't restore any backups including Google app backups and see if problem still persists. Don't even bother logging in with your Google account at first. Just see if issues are fixed.
Morning b4 coffee rant:. I'm so tired of hearing this, TMobile/OnePlus didn't "force update" anyone's phones any more so than Google or any other manufacturer. This is my first OnePlus phone, probably will be the last because of all the serious quirks in rooting and just horrible software engineering by OnePlus and I want to throw it thru the window sometimes, but that's half from me screwing with it lol. Anyway, so I'm not OnePlus's biggest fan, but they didn't do crazy by releasing OOS11. That's how updates work...People had been (rightfully) been expecting it for a long time. And I don't have a single issue with it.
My battery life is much worse also. I blame it on the constant/aggressive wifi changes.

They did force the update. There was no further postponement available. It's not cool that we have to jump thru hoops to take an OTA but the full version upgrade ignores root woes and forces itself to install. I don't mind jumping the hoops, so long as it's consistent.
I've never had this force update issue on any previous device. I've been able to ignore it indefinitely, and if rooted, need to do a manual intervention to take the OTA. I was in the middle of doing something when my phone shut down and installed a11.
This isn't my first OnePlus device. It is my first carrier tied/coupled OnePlus device. And will definitely be my last carrier coupled phone. I want to give OnePlus another chance. I had the 8 Pro and it was lackluster to say the least. I found a great medium with this device. It offered similar specs, 5G, good build quality at a reasonable price.
It may be true that other manufacturers force updates on some devices but it wasn't true for me with the Nexus or Pixel phones I had. Or my previous OnePlus device (5T/8P).
A lot of us are intentionally choosing OnePlus for the root and ubl friendliness with good specs.
I don't think anyone is saying A11 shouldn't be offered, it should be of course. It just shouldn't be forced and the safety net we thought we had to prevent that, was also swallowed up.
Give OnePlus another chance, this phone is not the typical OnePlus experience I've come to love. Or maybe this is the new OnePlus... I'm gonna give them another shot.
As a side note to this, my wife wanted the Samsung s21, coming from a OnePlus device. She is very disappointed with the s21 in just about every aspect other than the picture quality. Oppo and OnePlus are merging, I'm not even sure where to go after OnePlus

You can block OTA a couple different ways. I've done it for over 5 years with AT&T, no root needed.
My 10+ is still running happily on Pie.

Xiaomi/Redmi/Poco meets the root and ubl friendliness. In some countries, they still have warranty coverage after unlock bootloader.
Good specs or not is vague between different phones.
Check XDA Xiaomi category and see the reply and thread count. It's to some point a sign of better price to the specs.
Use GSMarena to compare the spec.

Sadly, OnePlus hasn't been typical OnePlus in well over a year. Look how slow updates are now even for their latest non-carrier flagships beginning around 7T time (and can start to be seen as early as the 6T).

Oppo and OnePlus are merging, like you said, so won't they still continue producing flagship phones at a manic rate, like Samsung? At least Samsung has gotten much better with the speed of OTA updates, while OnePlus has tanked.
We're guaranteed Android 12 for our phones. Let's see how long it takes for us to get it, probably more than a year after I make this post. The 6T is still waiting for OOS11.
To be honest, receiving the 8 Pro was disappointing. I had the pixel 2xl and it's the only thing I've returned in a decade. I got the 5T for half the price and couldn't believe how amazing that phone was. It's still alive and crack free. I put it through a lot.
Getting the 8 Pro, I knew it was $1k but I expected a lot. I was disappointed. I liked it but not $1k-liked-it. And I realized then, that maybe OnePlus had already ended their founding principles. I was most disappointed that nothing about the 8P was pushing the envelope. The 5T was breaking the envelope and the 6 was doing big moves with giant storage and ufs3 speed. After that, partially because of how well the 5T was made, I didn't follow what they were doing. I didn't need to. Now we are at OP9 and you may be right that 'that oneplus' isn't here anymore.
I did look at some oppo devices. I knew that's the parent/sister company to OnePlus and would find similar features. It just worked out that the 7T Pro 5G dropped right after I got the 8P and I traded back.
I guess I got spoiled

That's one reason I got this phone, OnePlus's prices are thru the roof. And no, I don't want any Nord crap. I want a flagship phone at a reasonable price. Got my 7T Pro 5G Mclaren for $500 brand new from eBay the day after the OP8/Pro launched. I just couldn't justify spending $1000 on a phone and I never will.

I feel like an idiot buying the SM-A215U :(

Without paying attention (because I had just broke my Galaxy S20-5G) I got a Galaxy A21 for cheap. I should have done the research but I honestly wasn't thinking. I didn't know this A21 would be stuck on Android 10. It's running the A215U1 stock rom build because I use Straight Talk, and I thought the latest stock rom for it would at least be Android 11, but it's not. I think I've gotten so used to Android 11 that being stuck on Android 10 is just really messing with my user experience.
So my question is, since Samsung doesn't seem to be releasing Android 11 for the A215U1 build, are there any custom roms with Android 11 floating around for it? I have a feeling that it's unlikely because when I finally decided to research it I've found pretty much nothing. But I figured I would come here to talk to the pros on XDA, because you guys pretty much know everything there is to know collectively.
If not, I was also given an FRP locked SM-A125 from a Telecomm friend who doesn't run any kind of MobileIron or MS InTune to be able to unlock old phones that employees turn in. The company doesn't want to invest in it, which just seems ridiculous, right?
The employee factory reset it without removing their Google account, and claims they don't remember the account email and password they created specifically for it. So the company literally just throws them away rather than deal with the process of sending them into Samsung with the proof of purchase to get them unlocked.
I've tried so hard to flash the right customization file on it to get to that service screen that allows you to remove the FRP lock, but I've been unable. I managed to do it once before for an S8+ that he gave me a couple years ago, but honestly I was trying so many different things that I can't even remember how I managed to do it. I'd at least like to have the A12 with Android 11 to use in the meantime, until (hopefully) Samsung releases Android 11 for the SM-A215U1.
It's only the screen broken on my Galaxy S21 5G, so as soon as I can get an extra $250 together I think I'll send it in to have it repaired. I just hope when I dropped it that something more than the screen didn't break internally. Anyways, even if you guys can't help, thanks for everything you all do here. Have a great weekend everybody.

I don't know much about the A21s, but I remember being able to upgrade my Samsung S4 to Android 9 back when I still had it. In all likelihood: Absolutely, you can upgrade your Samsung A21s to Android 11 - and probably even 12 with zero issues.
First two ROMs here seem to yield the results that you're looking for:
Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O
Improve your Samsung Galaxy A21s's battery life, performance, and look by rooting it and installing a custom ROM, kernel, and more.

I have a SM-a215u that was frp locked. I spent 2 days trying various fixes, pulling my hair out, and this was only effective solution...
I wouldn't worry so much about it. Android 10 is very good as is, Android 11 doesn't really add that much except for google trying to further lock things down and make life harder for running custom things, if I had this phone I'd just be on the look out for a solid custom Rom, something like LineageOS or based off.
I own a different phone, which had Android 10 and eventually got 11, but after trying 11, I much prefered to stick to my custom Android 10 rom.
I want some option to. The A21 is really bloated. I tried to remove stuff manually, but there a lot and there was not much change. I would like to try to install plain android, but even enabling EOM is tricky. and root to...
