Need help solving an issue, play store misbehaving on my SM-T810

Hello, I hope I can post this here.. i tried, i searched... can't find any solution to my issue.
Model : SM-T810 , with Samsung 128GB UHS microSD. OS : stock Nougat from Samsung.
Here is the problem :
On the play store, if there are pending updates, they only install one at a time, and then it won't do more. Like if there is 5 pending updates, it will maybe do one, and then the other 4 stay pending. It might only do the download portion of the first one and not go to the install phase. If there's no pending updates, and i try to install an app, only the downloading portion of the process shows up, it stops after that, it doesn't go to installing. I have to close the store and go back in for it to install, but if there's a queue of downloads (updates or asked to install multiple apps), I have to close the store for the same amount of apps in the queue for them to install one by one. Now I noticed that every once and a while, 2 or 3 will have updated overnight but that's it!
I closed the process, I cleared the cache, I cleared the data, I cleared the download manager's data and cache, i rebooted, i forced a wrong date and time then set it to auto-date and time to retry, etc.... I uninstalled the Play Store updates, nothing worked!!!
The next step was to do a factory reset. I did not want to lose some progress on some games, AND I have an app to read PDF files and did not want to lose read/unread status of my files...
So I used Odin to flash TWRP, did a backup, rooted, used Titanium Backup to backup my apps.
Then I did factory reset. Store behaved normally again! Installed a few apps, waited a few hours, still good. Did a restore of my apps from titanium backup, everything seemed fine, then a few hours later, store still was not updating or installing the apps right...
Did another factory reset, store worked fine, only restored a couple of backed up apps (the critical ones that i wanted to keep the saves from), everything worked fine. Over the course of 24 hrs, i re-installed a bunch of my regular apps via the play store. Play store worked fine. I did to another Nandroid backup with TWRP just in case.
Then all of a sudden, it started to lag a bit between clicking install, to downloading, to installing. And then a few hours later, issue completely came back, store won't install without me closing it between the download finish and install.
Now one of the last steps I did before it started acting up again was moving ONE app to the SD card (not using any root features). I'm not sure if that caused the issue to come back.
I did notice that Android left a bunch of files on my SD card, some Android folder, with a bunch of subfolders.
I'm wondering if the SD card could be the culprit... I will do one last restore from my last working Nandroid backup and not move anything to the SD card.
If it comes up again, i think i will move the data that i have on my SD card that I dont want to loose (my PDF, pictures, etc.) on to my NAS, and do a factory reset without the SD card installed. Maybe even re-flash with Samsung Kies... and forget about my Titanium Backup saves...
It's my last resort so I was hoping anyone would have any idea on what else to try before doing that?
One last point : yes the stores kinda slows down at some point where the download process takes a few seconds to kick in, and then a few seconds to installing, up to the point where it never does. BUT the rest of my tablet still is really fast, no slow downs anywhere else... All apps launch fast
Thanks!

Auto updates are bad. They just kill the performance of your s2.. better do such things manually.

Auto updates of the apps? Or the OS?
Apps i can see... but still... If I turn that off, that solves the issue of the auto-updates. But then if I want to update a bunch, they will only do one by one, i have to close the store and open again after each updated app.
But even with app auto-updates, if i want to install one new app on my S2, it will only download, but not install, i have to close the store and open it again for it to install. Then the next time that I want to install an app, I have to do the same thing again, close and open. It's like the download manager doesn't tell the Play Store app to do the install (or tell whatever app or service to install the APK...)

Thanks for the info.
I would check for OTA update but since i rooted mine, it won't do them...
I'd have to flash the stock rom from samsung again and loose my saved data... which right now i might be OK living without...
Anyone knows if I loose TWRP if i flash a stock rom with odin ? If so... am i better using Kies?

Fair, let's recap: you do not use stock rom. You have root, twrp, flashed this and that and a morbid desire to have always the very lastest version of whatever the app. And now the Play store doesn't work properly anymore.. d
Do you see the pattern?
But, hey, maybe you need even more *lates updates* to fix your issue.
Updates = bad performance and new issues in general. Period.

Wooooh, DON'T jump to conclusions here.
I was running the STOCK out of the box Android for the S2, no root, no TWRP. The issue started after one year of usage, and not only included updating apps but installing FRESH NEW ONES TOO.
The "flash this and that" came AFTER i ran into issues.
I also have a Note 5 supplied from work and for that reason I'm still runing stock, not rooted, and never will root it. I have over 100 apps on there, 5 email accounts (2 professionnal, 3 personnal), multiple google calendars, multiple outlook calendars, auto-update is on, it's been over a year and a half, if not more, and never ran into this kind of issue, ever! It's synced with my CPAP, my smart watch, and my headphones. And it's still goes the same speed and gives me the same performance as when i took it out of the box.
My tab S2 is my second Android tablet, before I had a Tab 3 that never gave me issues like that either, and always had auto-updates on.
Sometimes you need updates. Some online services might not work right or at all if you don't have the app that matches the features, like evernote, facebook, onedrive, dropbox, etc...
Or you get new hardware that requires an update.
Yes sometimes they include bugs ... which are fixed in a later version.

In my case I do have stock rom and have had issues with play store since update to Nought. It does seem better since last night's OTA update.

I saw multiple posts of people having different phones running stock having this exact issue for a while with no solution in view. I think it has to do with Nougat too... But my Note 5 is on Nougat and no issue... it might be brought on with specific services or apps running while on Nougat.

Thanks for letting me know about the OTA update. Since i was rooted, i can't get OTA updates, would have needed to wait for the 7.1 Rom to flash...
I ended up taking screenshots of the stuff i didnt want to loose (read/unread status of my pdf files, nevermind the save games) and then i used Samsung Smart Switch to reflash the whole thing back to strictly stock, lastest firmware. So far so good, crossing fingers

I*was*running the STOCK out of the box Android for the S2, no root, no TWRP. The issue started after one year of usage,
Click to expand...

Fair. So in this *year of usage* you never ever updated the OS?
And auto-update was of course *off*, right?
If that's the case, then clearly there must be some other issue with your s2.
Otherwise, you have merely confirmed what I have told in the very beginning: updates = bad performance and new issues in general. Period.
By the by, apps like evernote and facebook track and spy on you.
About your Note 5, maybe there weren't so many updates..

Yes in that year of usage I upgraded the OS from 5 to 6 to 7. Yes auto-update was on, for Android and for my apps. By stock rom i meant nothing flashed "this and that" like you said.
If you would read my other comments, you'd also realize that another member helped me more by letting me know there was an OTA update that helped him. I reflashed my S2 with Samsung Smart Switch and haven't had any issue with the Play Store since... that proves that updates do fix issues.
There's no OS versions, app versions, firmware versions on any devices that don't have any issues whatsoever. Updates might bring bugs but they also fix the ones from previous versions. If you think that anything stock out of the box never have any issues whatsoever, you're wrong.
Apps like evernote and facebook spy and track you? Really? And you're on a forum for Android based product and don't think that Google tracks what you do? If you dont sign in with your google account and only browse the web with your tablet, that's your business, but you can't go on forums and admonish people for doing otherwise.
Besides, this is a forum where a good part of the posts are about custom roms, flashing different boot/recovery loaders, different kernels, unlocking phones... and you're judging me because i do app updates, and flash "this and that" ?
Come on...

No judging here. Just pointed out the probem at hand.
You did update the OS at least twice.. see?
OEM updates = bad in general.
Sure, new updates fix what *previous updates* screwed up to begin with; sometimes.
I totally agree that there is no OS version that is 100% issue free, but -- why trying to fix something that seems to work?
You see, that is my whole point.
I told you about evernote and facebook because you mentioned to have them on your Note 5 which happens to be your professional work phone?!
Just be aware that Evernote steals content just like the FB messenger. And I mean literally. Your creative ideas become their property. You did agree to their terms! FB also records the mic(s) 24/7.
Certainly Google tracks and spies as well. Then again, you can deactivate or block (firewall) those services/apps.
Just remember, things that are *free* come with a price.

Niii4, I tried to subtely pass the message that I did not want any of your help when I said that SOMEONE ELSE helped me with their input and update.
I didn't say that I was using evernote and facebook on my Note 5 from work. Jumping to conclusions again.
You want to know what are the biggest secrets in my Evernote notes ??? RECIPES!!!!!
Oh no... they can read the oh so secret lemon crinkle cookies recipe that is available with a quick online search! Here's the link btw : http://www.laurenslatest.com/lemon-crinkle-cookies/
I came here after trying a lot of troubleshooting steps, when everything that I've tried failed. And someone else helped me.
All you brought to the table was misinformation about updates in general and spread paranoia on who is spying on who.
fonetyk asked you to stop that, and I asked you to stop that. So far my issue has been resolved and i'm thankful to the user Tabpro8.4 for his comment.
Please, please leave my thread.

First and foremost, this is a forum and thus other users that may encounter similar or the exact same problem(s) will seek to comprehend the whole issue at hand and not just one side of a problem.
Oh yeah, an OTA update seemed to have fixed it. Seemed.. for now.
Second, this is not exclusively about *helping you*. Apparently you are quite knowledge resistant, especially when facts are being stated that don't conform your general view.
True, you only have hundreds of apps on your work phone. But definitely not FB messenger or whatnot. Whatever. What's right is right, and what's fair is fair.
I suppose, you are probably right, the work you do must be of no interest for anybody in this world; at all. Same for your private life. Now, be a neat little sheep and go on chewing the green.. (while we are watching you).
Oh, and you stalking all my comments, telling people to ignore me is hilarious. Keep up the great whine. ?

Is samsung ruining our devices intentionally?

i have a display issue with my note 8 (N950f), the screen gets greenish and messes up the colors making it very unpleasant to look at (started happening right after september 2020 update) i could fix it by pressing the power button, taping the screen to turn on always on display but then it would switch back to that annoying green display after seconds or minutes (weirdly enough the Always On Display is always good and never shows any green), so i tried to fix it by : Factory reseting, clearing cache, flashing stock os, custom roms pie, 10, 11, nothing worked until i tried flashing a custom kernel (Phantom Kernel for Pie) on a stock os. that fixes the green screen issue temporarily (2 to 3 weeks) i mean it's still there but it gets green very rarely, until it starts to gradually get worse overtime. And also im not the only one! i found another user @B3anbeanbean who has the EXACT problem and he fixes it like i do with the phantom kernel. This can't be a coincidence.

If you have a fast, stable platform that fulfills its mission, leave it be.
My 10+ is still running very well on Pie and will be for the life of the device.
If Samsung doesn't break it, Gookill Android surely will. What applies to MS XPx64, W7 applies more so now with Android.
For all those "upgrades" what did you gain?
Rather than enjoying the device how much time did you lose? Which bring me back to my original statement.
Play games and don't let the game play you.

mate, i would've never touched the phone, i love pie and i dont mind using it, the problem occurred on itself on stock os i hadn't touched anything. i did those "upgrades" in hopes of fixing the display.

If it running right when first purchased it's likely hardware if a factory reset wouldn't resolve it.
When you start changing firmware rather than find the root cause you throw more variables into the mix. Making it more difficult.

Ever wonder what happens when one or a couple dozen of the billions of transistors in the processor fails?
Firmware doesn't just of a sudden fail, hardware does.
Firmware can get corrupted. Did you ever reflash the original stock firmware version back onto it?
You know verify the firmware load was intact?
You probably lost some digital pathways and/or memory cells in the CPU or another chipset.
The current firmware for whatever reason(s) doesn't use them.
Major carriers like AT&T, Verizon etc are partnered with Samsung and actively dictate what software and firmware goes in those phones to Samsung.
What could go wrong?

I personally never update, rooted and up... well (actually downdates) turned off for all its days.
although to answer the question directly, in my opinion yes spammy ruins stuff for more sales (aka rips off it's customers) then inturn they eventually never want to see a spammed cell again. so realistically they loose money, not a smart choice obviously, but when blinded by greed all kinds stuff will happen.

Notification Bar, Home, Recent buttons disappear occasionally since Android 12

Since upgrading my Samsung S10e OTA, the Home and Recent App buttons disappear, and also I can't swipe the Notification pane down. The only fix seems to be a restart. The problem happens reliably after charging for a while, and occasionally during normal use as well.
I have tried wiping the cache and pretty much every other setting I can think of. Any idea how to fix this so that I at least don't have to reboot!?

any ideas anyone?

I am wondering if your launcher/home app is crashing? I think that even if you use a third-party launcher (eg, I use Nova) these buttons are still handled by Samsung's launcher/home app? If that is sleeping or crashing, it may be why these are disappearing? That would be my only guess at the moment.
On older phones, when this kind of thing happened, I would put a launcher icon on the screen, so I could relaunch it. But I don't see an icon available for the OneUIHome app on my phone... but if you can find some way to get that it may allow you to restart it, and test this theory?

I am not using a 3rd party launcher. However I have tried using Nova (free) and it seems to have the same problem.
I have also installed Assistive Touch that puts a little floating button on the top that acts as home/last used/notification panel. Only the Home function works however so I still can't access the notification panel.
I really don't want to do a factory reset! Maybe the next update will fix it but this phone is quite old now so I don't know how many updates are yet to come....

Sorry, I don't have any other ideas. I have heard of people having issues with A12 in general, but not this one particularly. That said, if you do a FDR then you may consider going back to A11 and seeing if that resolves it. The FDR might do it as well, but you can't go back to A11 from A12, so you could do that and see how it fares... then do the A12 update (without FDR) and see if it comes back - in which case you'd know it's something to do with A12 on your phone...?
Sorry I don't have better ideas!

Thanks - do you know if there are any large updates in the pipeline after the update to A12? I ask since I had this problem when I first bought the phone and I think it went with the next large update. Back then (2 years ago or more) I could fix the problem without restarting by clearing the cache in Android settings which somehow got the buttons & notification pane back. Unfort there isn't an option to clear the cache in A12 (I have tried doing it in recovery which made no difference).

That's weird... I don't believe we can expect A13... so the only thing I'd expect is continued security updates...
I have avoided A12 because of the many issues I read about on the forums and elsewhere. I have no issues with the phone today, so I figure why bother, you know?

I've actually never encountered this behaviour, strange. Mine have a bright line on the bottom part of the screen and sometimes it shines more then other. But that's purely hw issue not software.
Regarding updates, Samsung is updating now with May 22 security patches, I heard they moved us to 3months cycle of updates, but seems they still comes out monthly. That's cool!

There are one or quite old posts about the same problem, and the suggested fix is to enter the following in ADB
adb shell am start -n com.google.android.setupwizard/.SetupWizardTestActivity
But on my S10e there is no SetupWizardTestActivity option available when I go into ADB.
Any idea?

Have you tried a different launcher app? Is the OneUI app being killed by something? I would think it should be eliminated from battery optimization in the stock ROM by default, but make sure it is. Beyond that, if you're using any battery-saving apps that could be killing it?

The OneUI Home app was "Optmised". I changed it to Unrestricted which made no difference.
In a previous version of Android when I had this same problem I could just clear the app cache in Settings and the buttons would reappear. There doesn't seem to be a way to do this in Android 12. I have tried wiping cache in recovery which made no difference.

Do you have other battery optimization apps installed? Greenify, etc? These may be killing it as well.
You can still wipe cache in Android 12: https://mobileinternist.com/clear-cache-android
If you had a workaround in A11, I might suggest going back to that - you should be able to (for a while, at least... once the BL changes you won't be able to).

V happy to go back to a11, but Is there a way to go back to a11 without doing a factory reset?
And excuse my ignorance but what is BL?

No, you can't go backwards without resetting.
BL = Bootloader. Samsung has been updating this and if you're on a later version, you cannot backtrack it (at least not on a Snapdragon phone). I realize now that I'm not sure which phone you have, so if you're on Exynos then the situation could be different.
As long as the A11 you're flashing has the same BL version as the one you have now, you can flash backwards that way. 5th digit from the end of the version number (eg G970U1UEU6IVD2) tells you the BL version. You'll need to get an A11 with the same version there, and it should be doable.
What's your full version number?

The full build version is SP1A.210812.016.G970FXXUFHVE1.
If there is a way to go back to a11 without doing a reset I'd love to know! Or of course just any way to fix this problem ..

Sorry, I should have chased this down first - you have an Exynos phone, so you may have other options. You'll need to re-post and say you have an Exynos phone, and ask people about this again... maybe others who are more familiar with Exynos can chime in. Sorry for wasting your time with my Snapdragon-related info.
In the future, it's important to mention you have an Exynos phone... or say you have a G970F... the "F" means the same thing.

S10 SM-G973F - huge stability issues

Hello everyone!
I'm experiencing very serious stability issues with my S10 SM-G973F running stock unrooted PDA/AP G973FXXUGHVJ5, CSC G973FOXMGHVJ5, MODEM/CP G973FXXUGHVJ1.
It started one day ago and the effect is apps crashing immediately after being started. And it affects all types of apps - Galaxy Store, Samsung Email client, banking apps.
Clearing cache partition seems to resolve the issue for a couple of minutes, after which the instability starts again.
I've never experienced such behavior with any Android phone so far.
Any ideas what could be wrong?

Try in safe mode.
Back up all critical data... probably not going any where good

In safe mode it seems to be running fine. Is there a memtest app for Android or logging tool that can help me identify the reason?

Were any new apps added or updated?
Power management and launchers especially.
See what's running in Developer options>running services and Device Care>Memory. In Device Care try clearing all the cache apps then when it starts to misbehave see what apps just opened.
I've used that method successfully and avoided a reload.

I see nothing suspicious. Clearing the memory from Device care doesn't solve the issue.
I guess next step is hard reset...

Find the root cause. Otherwise it's likely to reoccur after the factory reset.
The only exception to this is undeletable malware or a boot loop (which is where you might be headed).
Before a factory reset try setting all settings to factory; this is a major inconvenience but not as bad as a factory reset.
Best to find and correct the root cause instead... it's staring right at you, look for it.

Many thanks for your feedback!
Is undeletable malware even possible on unrooted phone? I haven't installed anything new lately and my phone is very stock... And I almost never install anything outside Google Play - definitely not in the last months... On a regular computer I would run a memtest in a preboot environment. As far as I see - there is no such option on Android...

Unlikely but not impossible. An app that passed the Playstore tests can latter update a malicious payload, so there's that. Occasionally the user may inadvertently download a trojan preloader (or other malware) or it may slip past the browser and download itself. If it retrieves its payload, boom; many times it does so through a second website (linked to the first) if you click on it or are redirected to it. It's important to check the download folder daily for anything you didn't download. Social media sites can serve as a haven for these packages and conveniently link the preloader and payload all on that site.
Always back out of bad sites or close the tab, or close the browser than open/close tab or if all that fails clear browser cache, or worst case delete browser data. Doing this can save you a lot of... fun Brave browser is very well harden, nothing has ever breached it. Samsung is pretty good but I've seen it breached. A trojan preloader made it through without me approving the download, but it was deleted before it retrieved its payload
Scan with Malwarebytes, it may spot it if present.
More than likely it isn't malware. Android 9 and above are reasonably secure unless you do something stupid.

Just for the record if someone is experiencing the same issue - 24 hours after hard reset it seems that the problem is gone.

Hello navy3dfx, trying to install phone info made a capture of the first 2 in info.
Maybe find out more about your S10 a 5 G buy or if you buy in a back market on that the concern., unlock any operator my Asia or US network chip.

Downgrading S20 FE 5G SM-G780G Android 13 One Ui 5.1 to Android 11

hello
i've never downgraded/flashed any firmware on this device before, so before i do something that might be fatal/result in bricking my phone i would like to ask is it possible to downgrade a S20 FE android 13 to android 11? while my one ui version is 5.1 i haven't updated the security patch to the april one (the one that changes your binary) it's currently the 1 march 2023 one
i've already checked & downloaded a firmware with the correct binary number so now all i need to do is flash it

Welcome to XDA.
You're limited by the bootloader version to how far you can roll it back. If the bootloader was upgraded too, you're boned. The 5th digit from the rear is the significant digit that determines that. If the rom's 5th digit is the same or higher value you can flash it. If lower, no go.

Hi, I downgraded my S20 FE several times from 13 to 12 with the same binary (obviously) with no issues at all, so you can downgrade easily.
In my experience on samsung devices (literally I flashed a hundred times on different devices) it's very unlikely that you brick your device with odin, even if you use a wrong firmware for your device....the only thing that it may brick a device is because it has a hardware damage

Hello
This will depend on your variant.
on the G780G (binary 3) and G781B (binary 4)
You can download to android 11.
since it has the same binary.
Of course, you should do it from 0.
do not install via CSC_HOME.
The installation must be clean.
before all make backup.

yes it is the same value
mine G780GXXU3EWB2
the firmware i downloaded G780GXXU3AUH5
which would make both binaries '3' right? would this be okay?

Or if the battery has insufficient charge or capacity. Any time you flash a device you take some level of risk. A power outage with no or insufficient battery backup for the PC would also end badly.
The risk is also greater with Androids because it's not a small couple dozen MB flash that's done in seconds. Lots more time and data for things to go wrong. If my Canon pro cam had a bad flash, Canon would likely repair for free or a reasonable charge. Samsung will do neither of these... repair cost plus a new mobo loaded with the latest firmware. perfect.

the CSC_HOME file
comes in the software you just downloaded.
unlike normal CSC.
The CSC_HOME is used to only update the system, without deleting anything.
in your case you are going to downgrade, use the normal CSC without _home.

thank you everyone for the help & answers

I'm referring about samsung devices based on my experience (trial and error), I had a lot of bricks, soft bricks and I was able to solve it with odin.

Yes, exactly. Why do you want to roll it back?
If it's a specific issue finding a work around may be easier.
Android 11 is no picnic either. I prefer Pie, Android 10 is ok; I'm running both and will likely never upgrade them.
Regardless you will need to lock it down so it can't do OTA upgrades/updates. That's the first thing I do on my Samsung's... once bitten, twice shy Upgrades and updates can and do break Samsung's... then you have find work arounds and fixes.

other than battery run out faster & the phone feeling a bit sluggish nothing specific....it's just i've already debloated my phone & disabled many features of the phone that i dont use and dont plan on updating my phone anymore and while that does help improve things quite significantly i just thought at this point why dont i just might aswell downgrade the phone
before i had this phone i was fine staying years with a phone that stopped receiving updates after android 6 lol just that it eventually ran its course and after several hardware problems & the phone giving up by itself (every 3 weeks or so it'll get stuck on bootloop for no reason) i assume it was time for me to buy a new one...too bad

I'm glad that's working well for you. I use to always be playing with my PC's like that. With Androids I took a more conservative approach; less down time, more play time.
I leave the firmware be on my 2 stock N10+'s. They run very good, fulfill their mission and it's simply not worth the risk or time. I don't allow firmware upgrades or updates. This N10+ in my hand is still running on Pie, firmware is 3.5 yo, and the current load will be 3 yo this June. No malware in all that time; security isn't an issue. Still fast, very stable with minimal maintenance. It's also heavily optimized and running well; I have zero incentive to change the playing field by altering the firmware.
My SQlite scores are lower than they should be in spite of my fast disk r/w scores so eventually I may do a factory reset to try to resolve that. Lol, that's the full extent of my ambition at the moment.

yep. i learned the hard way
i'm quite green at this stuff and at first i just thought "more upgrades & updates means good! i should get the most out of this device" but alas after some serious overheating & battery draining problems over loads of features i dont even use.....

Anything below Android 9 is suspectable to partition worming nasties like Xhelper. Run Android 9 or higher. Android 9 is relatively secure unless you do stupid things.
All Samsung's should be optimized. You will still have scoped storage running on Android 11 anyway. If you don't mind the UI of Android 13 I would try to find what's causing the issues.
Disable global power management then go after the power hogs on an individual case by case basis. A logging firewall is useful in finding them. Cloud, and social media apps are prime offenders. Try temporarily disabling Google play Services and see if this helps; Google backup Transport, Gmail and Playstore are dependencies of it. Enable as needed. 5G can also suck a lot of power and is inefficient when doing small bandwidth transfers. Wifi isn't needed if you have an unlimited data plan. Use Package Disabler or abd/ladb edits to take out the really problem apps that can't be resolved in settings. Don't go too nuts though; target the hogs and totally worthless apps like Digital Wellbeing. Most of the dozens a small Samsung system apps are best left alone as many modify the UI and consume very little resources. Understand what the app does and it's dependencies if any before disabling whenever possible.
Play with it...

i've done all that hahahah
other than youtube i don't have any other social media apps installed and i've already got rid of chrome & switched to a lighter browser
yep i like to experiment, i suppose the flashing stuff is the next step after all of that (yes have tried factory reset several times too, i don't mind as there aren't any important data in my phone but still, possibly getting a priceful item bricked over my messing around isn't something i'm too excited about, that's why i still like to ask around)
also what got me the idea was that i've also read from several people with the same device saying that with every android updates the phone gets even more sluggish

I learned the hard way with Samsung's too.
After the upgrade to 13 did you do a factory reset? If not, now is the time. Don't use SmartSwitch; do a clean load by importing all the critic data yourself.
At the very least clear the system cache.
I use Package Disabler to disable about 70 apps. It's not as bad as it first seems. Android 10 literally has about 100 more new system apps than 9. Most of those new ones should be left alone. My disable list for the Android 9 N10+ vs the Android 10 one is almost identical though.
Samsung's do lots of cool things so don't be too concerned until you learn more about the features. Bixby got killed right out of the gate; it's a hog and it's EULA is one of the worst I've ever read.
