MMB29M.G930VVRU2APE1 Update? / temp root working. Hmm... - Verizon Samsung Galaxy S7 Questions & Answers

What is contained in this update? The Verizon site is very lite on details.
Edit: Took the update.
Just a reminder for everyone to re-enable any disabled apps before updating. Android "optimizes" all the apps after the update.
I'll let you know if there is any weirdness.

any thoughts on it so far?

just got mine

Everything running great. 20 hrs run time. 4 hrs screen on time. Still at 35%. That includes 3hrs of streaming audio of the Royals game. Android usage seems better. Only 14%.

How does that compare to your battery performance before the update? On par, I'd guess?

Took it, haven't noticed anything new or any changes, good or bad.
Changes are listed here: http://security.samsungmobile.com/smrupdate.html#SMR-JUN-2016

One thing that is troubling me is now that Verizon seems to be pushing out updates in a timely manner will we ever see root? The devs are waiting for a security hole to exploit and now Big Red is actually patching potential holes on a regular basis.
Rooting these phones is a thing that definitely has a limited life...two years and everyone is lusting after the new "big phone", devs included. It wouldn't take many "patching incidents" to prevent root from ever being achieved.

Now that temp root has been demonstrated as working on an ATT US spec Qualcomm version, I'm kind of kicking myself. They have a ways to go, but it is promising. Hope updating doesn't bite me in the arse.

Has anyone tried downgrading via San mobile files and Odin? If not, I may try tonight.

FWIW to date Samsung has not blocked downgrades via odin. Assuming they don't change their stance in the near future you should be able to downgrade to a vulnerable version later on if you need.

Is that true for all variants? Or just Exynos?
ETA: I thought Verizon phones could not be downgraded at all.

Snapdragon as well AFAIK, it's at a bootloader level. Snapdragon has extra boot security measures like secure boot and both Snapdragon and Exyonos have dm-verity but that shouldn't affect anything in this instance. An equivalent example would be the "fastboot flash" route on Nexus devices. HTC and others have tried to stop downgrades but Samsung and stock Nexus devices have always allowed downgrading via Odin or fastboot respectively.

I just purchased and activated my s7 edge. It is asking me to update. If I am wanting to root in the future should I not update?

Root possible?

I know its too early but what do you guys this about rooting/custom roms for venice?
BB ceo said (something along the lines) that they will only make an android device if it is secured enough. WOuld that mean a locked bootloader etc? Moreover, it is using a much more secure kernel (http://berryflow.com/2015/09/blackberrys-android-slider-using-hardened-linux-kernel/) and i've read that some beginner's tools (eg enabling developer's options, sideloading apps etc) are blocked.
So what do you guys think? As for me, I believe in this community and i know one way or another, we will be able to install our favourite custom roms/apps on venice. Although I dont know if it would happen 2 days after launch of 2 years after the device reaches the market!
Btw cant wait for the device! I hope blackberry becomes a force again after this phone. I'll buy it the day it's bootloader gets unlocked + root is acheived
Do you have a source on the Priv blocking sideloaded apps? That would be very unfortunate. Locked bootloader is a given but I would still like to be able to install my favorite apks.
I can't see things like developer options/USB debugging etc being outright blocked. That just seems like a great way to alienate the majority of the userbase that a device like this is targeted towards.
This is my main concern... I want this phone, badly. But after having a G4, having to wait for root and still not having any decent roms I won't get the Priv if it doesn't at least get root. It's stock-ish android so I can deal with lack of roms but no root, no sale.
Sent from my LG-H811 using Tapatalk
No idea why anyone here thinks they would do that. Even on BB10 devices installing apks is allowed - and they sure wouldn´t do otherwise on an Android device - that would be crazy.
and yes, bl will be locked and encrypted - root - well that will be something to wait for.
:good:
Bootloader WILL be locked, that's a no brainer. But locking out sideloading, developer options is not possible without TOTALLY killing interest and sales. Blackberry desperately needs Priv to succeed. This is their last chance to avoid becoming the next Nokia. So no, we will have at least sideloading available. Honestly, it doesn't matter if they lock out all these essential features, if they release at least the kernel source and device tree day-and-date with the phone. If you have these, we're better off building a CM 12 (or 13:fingers-crossed ROM for the Priv.

hmm. So do you think it would be possible to unlock the bootloader or it can never be unlocked?
btw slightly offtopic, but is there any phone which has a completely locked bootloader (ie has never been unlocked)?
Welp a leaked pic about the security settings confirms developer options can be enabled, so sideloaded apps is probably a go to. False alarm, peeps!

Look at the recent crop of AT&T and Verizon Samsung phones. Their bootloader are locked up tighter then...... Well we will just say their locked down [emoji1]

http://i-cdn.phonearena.com/images/...aked-hands-on-photos-plus-official-images.jpg In fact, this image outright confirms that you can sideload/ use developer options.
I wouldn't count on too much. The developer options could have easily been changed and some removed. As BB main selling point is security I expect this device to be one of the harder ones to crack.
As for the bootloader questions. Yes there have been a few that were uncrackable, a dirty hack to by pass has worked on some.
I imagine root is just a matter of time. Unless they lock the system partition, which other manufacturers have done in the past (Looking at you HTC). Even so, it has been done and s-on/off has been cracked before. Alternatives to locking include e-fuses, like in legacy motorola devices.
Bootloaders on the other hand, we're probably going to have to get some concrete evidence. It is most likely locked in my personal opinion.
This is all just speculation. Hopefully Blackberry can find a good balance.

The efuze us still used in many devices and if I know blackberry they will have it check against its servers for security. Once it detects root it will most likely disable the device. Or most of the functions that use BB servers. Remember everything is routed through Blackberrys servers in Canada so if their servers go do so does the device.

I would be completely fine with them locking out the BB services when root is discovered. But locking down the hardware would be overstepping their bounds. It's our hardware, not theirs. I know that doesn't mean they couldn't still do it, I just think it would be a jerk move.
It would be like if Microsoft bricked xbox machines that have been modded. They don't, they just ban you from XBox Live if they detect it. I think it should be the same approach.
Yes but even MS has locked the bootloader on Many of their 32 bit machines now. Also I have a link that you might want to read where is passed then modding our devices at all will become illegal.

First time owner of an Android device, have a couple of questions

I've been an iPhone user for years but I've always wanted to move on to Android because of how much more freedom it provides compared to IOS. Jailbreaking was somewhat simple to do but Apple would be quick to patch that out and they are just so restrictive, on top of having weak hardware it was enough for me to want to move on. I've owned my Samsung Galaxy S7 Edge for a week now and I'm still getting used to this new OS and so far I'm finding the edge screen to be annoying because the way I hold the phone my skin would touch the edge and it would just make the side bar continuously pull out. Anyways I'm looking to get the most out of my new phone.
1. Is there any way for me to prevent my phone from auto updating? yesterday it said there was an update available and I didnt want to immediately rush into updating on the chance I would be missing out on rooting my device but then a couple of hours later my phone would light up and it would update all my applications as well as the firmware without my consent. As wonderful as that sounds I would prefer to make that choice myself so I dont accidentally update past a firmware where its possible to root. Even after updating is it possible to rollback at all or no? My device is now on 6.0.1 so I hope I'm not too screwed.
2. I have some preinstalled apps I am positive I will never use in my life such as Uber (I drive my own car) and Facebook (I dont have Facebook and dont plan on it anytime soon). I saw options to disable it but I would prefer if it was outright deleted so is it possible? I would like to save on the space that it takes up no matter how minuscule that may be especially on apps that are just dead weight.
My phone is Samsung Galaxy S7 Edge and my service provider is AT&T.
I'm exactly in the same boat as you, having just moved to Samsung/Android after using iphones since it's first release. It feels so great to have the freedom that comes with the S7 Edge.
I too found the edge screen to be annoying, but as soon as I bought my case ( OtterBox Commuter) that issue you describe quickly dissapeared, I beleive any case will deliver the same result, as you'd been griping the actual case and not the edge screen .
There is a way to disable your play store updates through the play store settings.
As far as firmware updates you can control these in the Settings - About options. However I don't beleive that Android updates are there to plug any capabilities of rooting Android, from my understanding as long as the baseband is unlocked, and that will depend on which version of the Edge you have then it will remain rootable regardless of any software updates pushed. However someone with more android experience is probably best to confirm this.
I'm suprised that your device came pre-installed with Uber and Facebook, I had to install them through play store and likewise am able to uninstall them. There is an app called package disabler in the app store but as the name suggests it only disables them which you say you have the option to anyway. I beleive a root will be able to fix that.

first time android user
To be very honest i did hands on many android smartphone but my love to windows phone always increase respectively
. Do you really think a hard core windows lover its gonna be easy to sift at android .
On the T-Mobile version you can hit postpone when it pops up and then schedule it.
Thank you ih8un for your response. I guess I'll wait until rooting becomes available in order to delete these preinstalled apps.
Can anyone confirm if firmware updates can patch out rooting? If yes how do I disable or prevent firmware updating? I cant seem to find that option anywhere in the settings.
*You have got snapdragon version which have locked bootloader so unless samsung and at&t push out official update that unlock it, it is unlikely your device will get rooted at least not normal method.
1.It is possible but unlikely that new update can make root impossible(assume that your s7 get bootloader unlocked and root by flashing supersu) but if your device get root in special way by using exploits(like jailbreaking ios) update will patch up exploit and disable rooting.
2.Uninstall preinstall app will recover no space for user since system partition has fixed size and separate from data partition.
(Preinstall apps is in system partition. User apps and data is in data partition)
Also once your device is rooted it will list your software as custom and disable ota update.

@RemixDeluxe couple things.
Package DisablerPro even though they don't uninstall the apps such as Uber it does disable and they won't show up in your folder nor update.
To stop automatic app update go to Playstore settings and check the do not auto update box.
As far as firmware update I took the update so no biggie
Since the bootloader on the G935A ATT is locked down tight I seriously doubt there'll be a root exploit but if someone does find one if you root you won't have to worry about auto updates because the device won't be able to take the OTA.
I use a thin Speck case and Case Mate makes a good case as well and they will eliminate the incidental screen touches.
I've had the Galaxy S series of devices since the S2 and I've got to say in my humble opinion of course you won't find a finer device.
Yes I've owned several other android devices as well.
I've bought the international S7 Edge and that device is fully rootable so if you can come up with the money it's an idea to consider.
Even the Tmobile S7 Edge bootloader is locked down now so that's out of the question.
I hope I've answered some of your questions.
Feel free to hit me up if you have more.

I'm confused by your post, I thought rooting the phone was the equivalent to jailbreaking on IOS as in it makes the device open source but by no means is it official by the developers of the OS.
So are you saying I can only disable updates once my phone is rooted? I mean how would I stop it in the first place so I can get root to begin with? sounds like a catch 22.

I dont care about applications updating since that doesnt affect the OS in terms of exploits but for firmware updates I want to be able to not update because I imagine Samsung or AT&T (whoever it concerns) would not want their customers to root their devices and have open souce access they arent suppose to have. Maybe I'm too used to Apple stomping out jailbreak and I should ease up with Android updates, this is all new to me so forgive my lack of understanding.

Honestly I doubt very seriously if there will be root for the ATT, Verizon, TMO s7 edge. Just like the s6 edge or Note5. There was root for a very short period for the s6 edge but the exploit was patched very quickly. It seems devs aren't even trying to find root for ATT devices since the bootloaders are so tightly locked.
As far as updates to the OS since root isn't available there's no worry about exploits being patched.
It sucks tremendously but the major carriers are more concerned with security than anything else.
Tomorrow my ATT s7 edge is going back to the corporate store and from now on I'll be buying the international versions outright.
I've been lucky since I've had a couple other devices that I was able to sell on Swappa to offset the cost.

Never underestimate the xda community even if it looks grim now I'm keeping a positive outlook that us variants will eventually have root. But maybe that's just wishful thinking. But there are plenty of modifications and customization options available to us without the need of root.
I have a couple of requests in regards to some applications if anyone would be generous enough to suggest anything.
1. Are there any applications to get free inapp purchases without root?
2. Anyway to stop ads in apps or while viewing youtube videos? I've tried a few adblockers but they dont seem to do much if anything at all.
3. I used this app on my iPhone called Mewseek which allowed you to download music on the fly and listen to it instantly. Is there any equivalent of that on Android?

SM-G935U Galaxy S7 Edge (Unlocked) - May 1st Security Patches

Had the Nexus 6P - but even with Franco kernel and normal use battery life wasn't long enough. Saw the release of the S7 Edge unlocked which was great so I went and picked it up from best buy last night. Big reason is the monthly update cycle and keeping everything patched from a security standpoint without the Verizon bloat and slow release cycles.
Went to check the patch level and saw "Android security patch level: May 1, 2016". Checked for updates and are none.
Anyone else experiencing this? Appears to be missing June for sure and the newly released July security patches.

Yep - same with me - no briefing feed when you swipe left - nothing there.
Wonder whats happening - would hope Samsung provides updates to their own phone.. ?
I'm guessing it's because the phone just came out that they haven't released an update with the latest security patches yet. They probably have to set up their update servers for this new phone and a bunch of other behind the scenes stuff to get updates rolling. I would assume that it will get something within the next couple weeks and then continue to keep up with the other variants.
Does this variant of the S7 Edge have an unlocked bootloader?
No unlocked bootloader - just not tied to an individual carrier i.e. verizon, etc. with the extra bloatware.
Still no updates yet to the SM-G935U.
Ended up returning it and going back to my Nexus - no updates really sucks.
Has anyone figured out how to get briefing on the left screen. I used that a lot and i can't get it to work. Even went to the play store and Samsung store, got briefing but it won't let me enable it on the home screen settings...?
I've gone round and round with Samsung support about this particular unlocked device. The bottom line is that they are saying OTA updates for these devices might not be available because those are normally pushed through the carrier. They suggested to use their Smart Switch tool to apply updates. Even though this is a terrible idea and they should use OTA (with the invention of non-carrier WiFi these days ), I checked using this tool and surprise... there were no updates available.
I'll spare everyone the entire conversation, but this is how it ended:
"We understand. If you have an unlocked the latest updates for firmware and security can be done through Smart Switch. If you have checked for an update using Smart Switch and there aren't any currently available, we couldn't speculate on when that may change. In many cases this wouldn't be delivered OTA because OTA updates are normally pushed by carriers. Unlocked devices may not be able to get updates directly from the carrier currently being used. ^Jay"
Mine just updated today with the August 1st security patches. If had to guess, they waited until the Olympics were over since they handed these unlocked devices out to every athlete in attendance and they didn't want them receiving updates during the event.
Hopefully now that the unlocked models have received their first update, they will continue to get regular updates at the same time as other variants.

Thanks for posting this one, thats good to hear. I wonder if they will proceed further. Good to hear Samsung's infrastructure will support updates in the future. I wonder if its only for security patches or if they will do incremental updates to OS as well, like Android N for example.
Just got this tonight. I didn't have automatic update turned on but I checked and this showed up. Idk if i should do it or not.
I'm on T-Mobile with the SM-G935U. I got the update a few weeks ago and now it shows the Aug 1,2016 Android security update.
As far as root and bootloader unlock should i not do the update or just go for it?

Does anyone here own a Samsung Galaxy Tab A (8.4) (SM-T307U)?

Seems like a simple enough question but I've been having a really difficult time trying to gain traction about information on this tablet or any tablet.
Yes. i've owned one since is was released last year but there is NOTHING on xda. Even though it's new and fairly speedy, no one has worked on an ROM for this. I wanted to unlock and root it so I can use it on another ISP/Mobile.

No need to root to switch to another isp. get unlock code from current isp, install odin 3.14.1 and install any isp firmware you want from https://galaxyfirmware.com/model/SM-T307U/ I had an at&t branded with android9, and now i am running wind/freedom android11 firmware.

Hi, thnx for the useful info. Did you have trouble getting the unlock code from at&t? Where did you enter that code? A specific app on the at&t rom I'm guessing?
Getting a sprint version of this device, but want to use it t-mobile. Have read that just factory reset device and use odin to flash other firmware would work, does that sound feasible to you? I'm kind of doubting that but have no idea really.
It used to be flashing diff rom would sim unlock, but not anymore I don't think.
thnx for taking the time, so little info for this available.
cheers
No problem with at&t, although i had to impersonate a US location. Start here: https://www.att.com/deviceunlock/unlockstep1
Like I said, vendor unlock, install odin on your pc, use odin to install the desired firmware you downloaded.
The firmware should boot up, but maybe the radio bands are different between the two isp's? and therefore the LTE part of the tablet may not work. i don't care since I don't install a sim card, just use it on wifi.
Thanks a lot for the info guys. For anyone else reading, I used 'T307UVLS6CUH1' (BMC) - and it is unbranded and doesn't have a ton of bloatware.
Also, since there are so few users on this thing, will also drop that I made a stand for it here:

This is a horizontal stand for the Samsung Galaxy Tab A 8.4 (2020). Admittedly it is a bit specific because of the not-so-popular tablet and the use of a NetDot Gen10 magnetic USB cable. One could use this with USB-C directly - but I do really recommend that (likely stress on USB port). You...

Hello,
I got unlocked ATT SM-T307UZNAATT from eBay.
My provider is Red Pocket, and I have ATT-compatible SIM.
When I try to place a call - ATT window appears and askes to log in to ATT account or create one.
How could I place calls?
Would appreciate any help!

Thanks a lot for the info guys. For anyone else reading, I used 'T307UVLS6CUH1' (BMC) - and it is unbranded and doesn't have a ton of bloatware.

How is the speed/lag? This tablet is mega slow, but I was wondering if I loaded different firmware (currently on AT&T) that it might help, since it can't be rooted.
My 8-yr old rooted Galaxy Tab S 8.4 is better than this thing, but alas a few apps won't run on 32-bit architecture. I think I will relegate this AT&T "brick" to my exercise bike for an entertainment interface.

Meh - no better. It is pretty ridiculous - I was very happy with my 2015 Galaxy Tab S2 8.0 - but it started crashing all the time. This one is slower, thicker, lower resolution, and heavier! 32 GB really isn't enough storage either.
It is super annoying there are not any good 8 inch Android tablets. The Huawei M6 8.4 looks okay, but being in the US it is a bit of a pain to get.

The only great 8" tablet is the Lenovo Legion Y700, running SD870 with 12gb ram. 2560x1600, but IPS and not OLED.
I own the Tab S 8.4 (2014), the Tab A 8.4 (2020) and the Y700 (2021, 8.8").
Tab A is terrible.
It's painfully slow.
It needs root.
It has the same RAM as a tablet 6 YEARS older than it, with LOWER resolution and ! much worse performance. I wish it could be fixed.... Android 10 Lineage is out for Tab S 8.4.

I have done quite a few mods/tweaks to system/Global/Secure settings and also disabled Gaming Optimization Service (GOS) via Alliance Sheild X, it has made a MASSIVE difference. This device's (SM-T307U) performance is being HEAVILY limited by software-based restrictions. Most of which can be disabled without root. I can go into more detail as to how ive sped up this device if anyone is interested.
NOTE - If someone has the ATT version and can drop the .IMG or Firmware .zip that'd be awesome.
Ill keep trying to find a way to root this device until i get a new one, if anyone else has any success, DM me.

I've already deleted, turned-off and disabled everything I can. It's a good bit snappier, but still a dog.
I actually have 2, so I may play around with deleting/disabling apps via ADB. But it's not battery drain, which with some securetask special permissions I've gotten it to SIP power while the screen is off (varies, as low as 2% per day up to about 6-7%).
I checked the usual sources and couldn't find any AT&T image files.

Yeah this this is good on power, it is just severely limited. Judging from similar devices with the same exynos processor, there's got to be something holding it back. I again recommend using SetEdit or something similar to modify some params in the settings tables. The line I highlighted is in both this tablet and my Galaxy S22 & S21. I also found a param in there called "Enhanced CPU responsiveness" which was set to off, after turning that on, I noticed a massive gain in my tablet.
Also worth noting is I added the line "Allow_more_heat_value" with a value of "30" and it allows all cores to boot to max.

I'll have to give this a shot. I wouldn't think AT&T throttled the CPU, which means Sammie did it for some reason. Probably to hit some sort of battery life benchmark. Or maybe it caused instability in some devices. But being a mid-tier processor you wouldn't expect that it needed to be throttled.
I believe Sammie is giving up on the Exynos processors. I bet they had issues on this tablet, said "screw it" and just **** this out with a throttled cpu.

It's 100% a Samsung related throttle. From my understanding, it's done because they use many of the same parts/processors in various devices, so as a way to control device specific performances, they set limitations. For example, this tablet has the same processor as some of their other "Higher-end" models (if I'm not mistaken), so to keep this tablet from outperforming the others, it's limited. I'm sure there are other reasons, like the battery benchmark bit that you mentioned too.
But yeah. This is 100% a Samsung based throttling.

Can you please share the mods/tweaks you've done?
I have one of these purely for its size, I travel over Europe and as the seating space is limited the smaller the better. I am running the Canadian Wind software but if anyone can give me a run through on disabling apps/services to speed up a bit that would be helpful.
I am going to buy the Lenovo Legion Y700 but only when a global version with LTE is available.

Why is the Samsung ecosystem such garbage?!?!

Mini-rant
OK, so I have to rant (just briefly) about the whole state of Samsung phones at the moment. Basically, we spend gobs of money on expensive devices and get locked down pre-loaded junk in return. Oh, they are physically impressive, have good specs, and are aesthetically nice gadgets. But would you spend $1600 bucks on a new laptop that came with software you couldn’t remove and could only be upgraded for the next 4 years?!?!
I have wanted to experiment with LineageOS for years. I bought a used Samsung S8+ in 2018 and quickly found out that LineageOS was a no go because Samsung locks the bootloaders on all US and Canadian models. So, that was never going to happen unless some guru found a hack.
Now, five years later, I went out of my way to find a Global/European S10+ (an SM-G975F) specifically so that I could install LineageOS. Now, I managed to do that easily enough. But now I am stuck with a phone that has poor reception and slow LTE speeds because it is missing LTE bands used in Canada (i.e. the SM-G975F uses different bands than the SM-G975W).
So here we are… making tradeoffs again.
And while I like fiddling with things like this, I have to wonder... why are we here in the first place? I just want a phone that doesn’t come preloaded with junk that I don’t want. I don’t want Facebook, Instagram, WhatsApp, TikTok or even Office 365 pre-installed and non-removable. It is like moving into a new house and finding out that the builder picked out furniture for the living room and, while you can push it off to the side and cover it with a blanket, you can never actually remove it. Why is the builder picking out furniture for me in the first place?
Some will say they like the furniture the builder picked. Most will say they don’t hate it or that they found a way to cover it up sufficiently that they don’t really notice it anymore. That isn’t really the point though, is it?
LineageOS on the other hand comes with nothing that it shouldn’t. Oh, and you can have LineageOS if you like (if you stand on your head and find a way to order a phone from another market) but then you have crummy reception forever. Oh, and when you are done you are a 2nd class citizen who can't use the NFC chip on his/her phone to pay for things because you were a "bad person" who found a way to remove the builder's sofa from your living room.
Oh, there are tricks… download this tool or that… but some don’t work anymore because of update XYZ…
Why can’t I just turn on the LTE bands I need??!?! Like, seriously, why not?!?!
Or better yet, why doesn’t my phone do it for me when it sees the Bell SIM card?!?!
Whose phone is this anyway?!?!
The state of Samsung phones in North America is garbage. Full stop. Pure garbage. No, I am not being too harsh.
1) All phones should come with basic firmware that makes the phone work and nothing else. The phone should not be used as an on-ramp into whichever ecosystem is paying the manufacturer more. OEM apps (i.e. Samung Calculator, Samsung DeX, etc.) are fine but no 3rd party junk like Facebook and Instagram. That is what the store is for.
2) All bootloaders should be unlockable and re-lockable once custom firmware is loaded if that firmware is itself signed. No "tripping Knox" or this nonsense.
3) All radio/LTE/carrier settings should be accessible and customizable with easily selectable presets for major carriers worldwide.
Anything else is a closed ecosystem that doesn't respect your basic property rights.
OK, done ranting... Maybe someone from Samsung will notice and maybe it will make a difference.
Best regards,
The Fish
I run two stock N10+'s, a N975U and a N975U1.
Running on Android 9* and 10 respectively. Neither have had their firmware upgraded. I use Package Disabler to block about 70-80 apks and settings are heavily optimized. Both run fast, stable and fullfill their mission with almost no issues and little maintenance. Excellent SOT and standby time.
Both are compatible with AT&T and as such there are no reception issues. You check and verify this before you purchase. Slam the sim card in and they're good to go. Once optimized and running well, don't upgrade firmware or update apps and it will run fine for years. Don't do the above and you will need to find work arounds... if they exist.
Current load on this N10+ will be 3yo this June. No malware during that time. Still looks, feels and runs like new. Only repair has been a battery. After a steep learning curve I'm very pleased with these devices. They are still a joy to use. However I can't say the same for the proceeding Samsung flagships and will never own one of them for a litany of reasons*.
Samsung phones with/in this SOC/generation can run well in capable hands, stock, if used as described.
*has last Android 9 firmware update
**lol, don't get me started

This kind of proves my point. I am not saying there isn't a way to get your Samsung phone running the way you want it. I am saying that the hoops we have to jump through and the tradeoffs we have to make are unacceptable.
Why do you have to use Package Disabler to block about 70-80 apks?!?! Why should you have to block *any* APKs at all?
Why do you have to stick with old, outdated firmware? Why do you have to make this tradeoff? Why do we have to have a hostile relationship with Samsung?
Why can't we have a nice phone, no bloatware, no junk, no apps we don't want. Get updates for a reasonable amount of time (i.e. till the hardware no longer supports it)?

Sure. And I knew ahead of time when I purchased the Global S10+ (the SM-G975F) that it didn't support all the same LTE bands as the Canadian model (the SM-G975W). But again, I had to make tradeoffs because I wanted to run LineageOS. Again, why do we have to choose between two crummy options?!?! Where are the good options?!?
I am daring to imagine a world where this is better. Really, we used to have phones locked to service providers and 5-year contracts. Those were the bad old days. But these days right now (with the bloatware, etc.) are also not great. It reminds me of the Windows XP era of PCs where you would buy a new PC and be prompted to sign up for 100 different services upon initial bootup. Only difference then was you could re-install the operating system on your PC and free yourself from the OEM bloatware. But now, with phones, they make even that impossible with locked bootloaders.
Basically, if I could unlock the bootloader of a Canadian SM-G975W that would be ideal. Any why isn't it like that anyway?!?! Isn't that the way it should be to begin with?
Locked bootloaders with no option to unlock should be illegal.

Updates and upgrades aren't needed on an optimized device that's running well. New phones with the newest firmware are running like crap in case you didn't notice. Very little speed increase in most routine activities and horrible SOT on most.

It's not that bad if you shop smart. I bought out my AT&T N10+ at 2 years. It's almost identical to my carrier unlocked variant. I want the boot loader locked for security. No way I'm touching the firmware as these are premium flagships that run extremely well as is. I have very little to gain and lots to lose... including time.

You buy Samsung flagships for the premium hardware and then work within the framework that's available and what works best for you. You can root the Exynos variants but their hardware is almost always inferior to the Snaps. Consequences.
At this point both Samsung and Android newest products are so out of line that they are unusable to me. I don't care what they do, screw them. I'm in a holding pattern for 3+ more years happily using my N10+'s... I don't care. All my issues are worked out because I threw time at them to do so and I'm very satisfied with the outcome.
In 3+ years I will reevaluate the situation and decide what to do. Right now as things stand I don't reccomend any new Samsung's or anything Android version above Android 10. Unfortunately I have no easy solutions for you other than what I did. Even that isn't simple fix but it's a zero risk fix. I refuse to risk damaging these N10+'s by mucking with their firmware unless its needed for repair.

The reason I purchased this specific model was so that I could run a custom ROM. But the connectivity issues are not caused by the custom rom. They are caused by the fact that I am using a phone designed for a different market where different LTE bands are used.
And yes, I knew that ahead of time. And I am not regretting that. But you are missing the point. The radio in my phone is perfectly capable of using the LTE bands that my carrier uses. So why shouldn't there be a straightforward way to enable them?
What if I used to live in Europe and moved to Canada? Should I be forced to buy a new phone just because Samsung doesn't let me change LTE bands? Or if I travel between Europe and Canada on business then I just have to suffer with crummy reception?
My point is one of ownership, property rights.

Connectivity is paramount. Regardless of what your user rights should be, you need to work within the limits of the options available. The square peg round hole thing...
You may be able to enable those bands and that's probably where you should be directing your energy. I purposely try to avoid having to do that as much as possible and never had to. You dove down the rabbit hole, hopefully it's not too deep. Try looking at the hidden phone user settings first... I guess.

Yes, I agree. Being a phone is the most important thing that a phone does. And I am directing my energies in that direction as well. But in the process, it occures to me that a messed-up antagonistic anti-customer ecosystem this whole thing is. We would *never* accept this from a computer company, a car manufacturer, or a home builder. Yet, for some reason, we accept it from phone makers like Samsung and that we need to work within these [artificially imposed] limits.
Anyway, yes, there used to be a hidden phone menu (why hidden?) that would have let me enable the bands that I need. But Samsung removed it sometime last year with an update. Again, why?!?!
I'll keep looking. I'm sure I will figure out something in time inspite of Samsung, not because of them.

What OS version are you on?
The band selections are probably still there although means of access may have changed.
My knowledge in this area is very limited. The sim card always configured it perfectly for me.
Best to check with your carrier to be sure that phone model is on their white list.
You could try seeing if someone help you from your carrier tech support...sometimes you get lucky if you try enough.

The band selection app is categorically *not* there anymore because it A) it was part of the Samsung firmware and B) even if I was on Samsung firmware it wouldn't be there anymore either because Samsung removed it.
There used to be a tool you could download that would allow you to access the "hidden" band selection app. But it stopped working because Samsung removed the hidden app altogeather. Like I said in my original post on this thread "Oh, there are tricks… download this tool or that… but some don’t work anymore because of update XYZ…"
My point is that the whole nonsense of disabled bands and locked bootloaders is infuriating. I is like buying a computer that can only access the internet at full speed in Europe and if you fly to Canada and use it there you get penalized with 1/2 speed. Oh, and even through you could change it with the flip of a switch that switch is buried, disabled, hidden behind locked doors.
The Google Pixel 7 Pro has all the bands turned on (i.e. there is one phone for the whole world) and the boot loader is unlocked. Just saying...
At some point I will probably prevail in getting the bands I need turned on. And then I will likely be very happy with this phone for the next 5+ years. But none of that changes the fact that this anti-consumer predatory behavior on the part of Samsung is unacceptable.
