I have a galaxy s8 unlocked I bought from best buy & I'm looking to downgrade from Pie back to Oreo but have no clue which firmware I should download from Samsung, anyone know which version I should get? I see carrier versions & others like XAA & XAS & I have no idea what those mean.
[Samsung Galaxy S8 Questions and Answers] johnequickiii:
Apps button turned on over night and won't turn off.

My friends S8 is behaving oddly all of a sudden. The App Button decided to turn itself on at some point, and the setting to turn it off refuses to persist. She uses the gestures, so has no need of the redundant button.

Was wondering if anyone has any insight as to how to go about turning it off and having it stay off.

Thanks in advance for any assistance. ^^
[Samsung Galaxy S8 Questions and Answers] submin_:
After updating to Pie, my S8 seems to have forgotten the ability to keep web pages (opened tabs in Samsung Internet Browser and/or Chrome) in it's memory while multitasking. Before updating, I was able to leave some tabs open on the browser, and then when I took my phone from my pocket or opened the browser after using some other apps, the page I had left open would still be there. Now it always refreshes the page. I have disabled all battery saving options for Samsung browser and Chrome that I could find, but it won't help. Sometimes the web pages don't even keep loaded while switching to another tab and then back.

This is frustrating AF, since every time I switch to another app (for example Whatsapp), and then back to the browser, it loads everything from scratch...

I'm sad to hear you have the same problem, but on the other hand, it's nice to know I'm not the only one.

I really wouldn't want to do a full reset, since setting everything up again is a real PITA.

Hi guys, i have a big problem and i beg you guys to please help me out. I'm using s8 950F variant. The fingerprint sensor is not working. It shows "An error has occurred with the fingerprint sensor, if this message apears repeatedly please restart". I did everything i could. I dialed *#0*# and tried to test fingerprint sensor but i showed "fingerprint version: null" then i thought i should clear fingerprint app data. I went into settings>apps>system apps. But the offical fingerprint app was not found. Also tried safe mode.

Conclusion::::::

*#0*# test shows fingerprint version: null and the fingerprint app has also disappeared.

Hi guys

I am rooted and installed a custom kernel and Rom (Android PIE) - G950FD - (btw I am using Soldier9312 Rom & nx Kernel)

in the case I want to go back to Oreo (custom rom) what should I do to downgrade???

I really want to try the renovate ICE Rom
[Samsung Galaxy S8 Questions and Answers] PROGamer_199:
Hi, noob question.

Hi, I've been thinking about rooting my Samsung Galaxy S8 for some customization mods that are pretty nice, and also have some uses. But I'm worried about losing S-Health, Knox and Secure Folder (I'm a pretty heavy user, I use them every day, most of the time). I've heard that if you don't do any heavy root stuff like custom ROMs or custom Recovery then Knox won't trip, is it true? If not, is there any way at all to use Magisk modules and still not trip Knox?

Guys please i need help, bought this phone, SM-G950U, it is USA unlocked, right?

no OTA update for PIE, how can it be?!

I look up on sam mobile and looks like my phone is from verizion, how is this possible?!

Can i just flash the snapdragon pie rom on it or it will block my SIM or something like that... really pissed how things works over there.
[Samsung Galaxy S8 Questions and Answers] staMerrill:
Hi all, curiously I'm having the same troubles as [MENTION=5083483]williamtavares[/MENTION] but kinda in reverse. (I also just asked this here.)

I have a carrier unlocked SM-G950U that was previously on T Mobile that I now have on Verizon, (long story, see below.) However, my device isn't updating, as seems to be the case for a lot of migrated SM-G950U(s). Of course, I want Android 9, and I also wouldn't mind getting rid of some of Verizon's bloatware. I was also fortunate enough to have received a research grant for some work in Italy, and I'd like to bring my phone along, (I'm a student.) So really, 3 reasons:

I want Android 9.

I don't want Verizon's bloatware.

I want to be able to switch carriers without the painful process of a carrier unlocked phone. (Ie., with the unlocked firmware my understanding is that I only need to restart my phone, as opposed to resetting my device, to switch carriers/SIMs in the carrier unlocked (ie., non-U1) device, (I think.))

I want to flash an SM-G950U1 ROM, but I'm not sure if this is still possible, (though according to here and here it was possible about 2 years ago, on different firmware/bootloaders.)

My plan is to do this:

Download this G950U1UEU5DSC1_XAA from updato. (I believe XAA is the unlocked region code. My device is already carrier unlocked.)

Flash with ODIN (3.12.3, as far as I know only making sure repartitioning is UNchecked.)

I have a Snapdragon device.

Will this brick my phone?

Alternatively, here says I can download any carrier version of G950USQU5DSC1 (except Verizon and Sprint,) flash it, and it will work. I think this only accomplishes my getting Android 9, however, as it is still a carrier branded ROM. (So I'd still have to deal with bloatware and (possibly) resetting my device to switch networks.)

Phone INFO (the app) lists:

Original CSC Code: [blank]

Firmware's CSC Code: XAA

Active CSC Code: VZW

Avaialble CSC Codes: [a bunch]

Bootloader Version: G950USQU5CRG3

CSC Version: G950UOTN5CRG3

Baseband Version: G950USQU5CRG3

Build Number: R16NW.G950USQU5CRG3

Long story of how I got a carrier unlocked (SM-G950U) and not unlocked (SM-G950U1) device:

I purchased my "new" device on Amazon through a third party about 3 months ago. I checked the model number and found SM-G950U, but a couple places online said that this was indeed a regular, unlocked S8. However, my device wouldn't update, and I could see that I was stuck on a mid July/August build of Android 8, (CRG3.) Now that the summer's getting closer, I need(ed) to make sure my device is going to work while in Italy, so I called Samsung to update it/make sure it would work. They told me my device was previously activated on T Mobile, unlocked, apparently refurbished and sold to me. I rechecked the Amazon listing and it was in fact listed as new. (It was alongside Amazon's own listing for the S8.) Unfortunately, after spending the second half of my day on support calls, I won't be able to return my device because it's been just over 3 months. Looks like my next best option is to update/maintain it myself.

[Samsung Galaxy S8 Questions and Answers] Ruedii:
I have an S8 Active (Model: SM-G892U Device: cruiserltesq)

There are no AOSP ROMs that I know of that are made for the S8 Active, although a few are made for the S8.

I noticed everything is pretty much the same except the battery capacity (and shell) between this model and the regular S8. I know that the TWRP recovery uses the same version for both the S8 Active and the S8, even though it is different for the S8+, Would it brick, or otherwise break the device to flash a full system ROM made for the S8?

How much effort would go into porting an S8 AOSP to the S8 Active, considering that the difference is a minuscule number of variables regarding battery size, model number and device name?

G950F - No recovery after Pie OTA update

Hello guys, i'd need your help, here's my problem : I recently changed the display (+ battery) of my broken galaxy s8 G950F and made it work again. With no hesitation, I accepted the OTA update from android 7 to 8 (+/- 450 Mo) which was a success, so I accepted the next OTA update to android 9 (+/- 1 Go) but the phone was then stucked in a bootloop (vibration, fixed samsung white logo for 5 sec, screen off, loop), which did'nt worry me at first me because I knew it would certainly need a wipe cache from recovery mode. The problem was that i could not get access to it...

You know how it goes : you think "it's a simple update, there's no risk and even though, I'll find a solution" That's why I didn't pay attention to the last functional firmware's number and didn't activate debug mode for OEM unlocking. The only thing that I was able to do was entering in download mode through which I successfully flashed the last official firmware (BL, AP, CP, CSC) for my country found on Sammobile [Android 9 G950FXXU4DSBA - G950F PRO BELGIUM] but still, bootloop and no recovery.

Then I though it had something to do with bootloader version and tried to flash a previous one but got a downgrade error wich made me notice that all android 7 updates got a v1 bootloader, that the android 8 updates got a v1-2-3-4 and that the only android 9 update available for my country (Belgium-PRO) had a v4 bootloader. What was my functional android 8 version ? Did I jump from 1 to 4 ? Could-it explain this kind of problem ? I can't answer those questions.

I kept trying other solutions : Odin-flashing another country firmware ? PASS but no difference. Update with Smart Switch ? Device not recognized. Flashing TWRP recovery ? OEM locked. ADB mode ? No debug mode. Nand erase and Re-partition with .pit file ? Nothing. Using Odin 3.12/3.13.3/patched 3.13.1.3B/princeComsy 3.12 ? No difference. Extracting firmware's files to compare their structure ? Useless.

What should I do next ? Is there a any way to unlock the bootloader and install a custom recovery just by using Odin ? I spent a lot of time trying to resolve it by my own and didn't get any results so, any suggestion, idea or link to pre-existing xda post from you guys will be fully appreciated. Thanks in advance.

Faulty headphone jack?

So ever since I got my Galaxy S8(Plus if that matters in this case) I've noticed that any headphones other than the stock AKG ones are really, like really easy to get loose and fall off the headphone jack.. Recently it got much worse and I am now unable to even use any headphones unless I hold the jack in place or it just jumps out a bit, enough to lose connection and fall off. I was thinking maybe there's stuff inside the jack that is interfering, but I'm not sure how to clean the jack without damaging it and if that would even fix things. Do you guys have any ideas why this might be and if any of you are also experiencing something similar?

Change CSC from INS to BMC

Hi All,

Noob here. I have a S8 plus (Global Variant) SM-G955FD which I have used in India. Volte and Wifi Calling were working fine. However I recently moved to Canada and here am using the same phone. I do not get proper network signals in my basement apartment and have asked my provider (Bell) to enable Wifi calling for my account, which they have. I have seen it for myself as it shows up in my account info. However the menu option to toggle it ON isn't visible in my phone. (I have checked in the Call settings and Connection settings as well.)

Based on my research, I found that I have to switch my CSC code to BMC In order for the phone to recognize my Bell Sim card and enable the settings. Is this correct ?

If it is correct, can somebody guide me through the process. I also want to know if I would lose my dual sim capabilities if I change my CSC. Also I want to know if there is a way to avoid root as I use Samsung Pay here and do not want to trip Knox. (No warranty but Samsung Pay is awesome). Please help and guide me through the process please in a step by step noob friendly way if possible.

Jio Volte- imported S8

Hello everyone, I have a UAE imported Samsung S8 running android 9 and I am trying to change its CSC to indian version for use with Jio volte but I am unable to do so. I have tried to change it manually using the code in dialer (*#272*imei#) but its not working. Also tried to format the phone with a Vodafone sim in Tray 1 thinking it would automatically switch to indian csc(read this on some thread here only but it was old). Now downloading the latest indian firmware from sammobile( pathetically slow download speeds but no alternatives) hoping that flashing the indian firmware should resolve this issue. If there is something else that I need to do, please advise. I am attaching the screenshots of phone info app for the csc and pda versions.

I wrote this here because for some reason I can't make a new thread

So I have the SM-G950F and I've been using lineage os for a while but I always switch to my old rom because of the bluetooth. I use Bluetooth very frequently and having this issue has annoyed me very much. So the problem is that when I connect a device with my phone via Bluetooth it automatically disconnects after 30 seconds of inactivity. That's not the only problem - also when it connects and I start listening to music or any audio it lags a lot and I can't hear most of the song. That's annoying and I hope someone helps me fix it because I really like lineage os.

My wife and I have ATT S8's which were updated OTA to PIE a couple of months ago and since then, we have been fighting with high battery drain. I've done several full complete wipes and even replaced the 1.5yr old original battery, yet still, the phone drains with little to no use. By afternoon, the battery is down to the teens.

I'm 100% convinced it's PIE, based on other complaints of battery drain since their S8's were updated to PIE. So I want to downgrade to stock ATT OREO. I'm on PIE G950USQSDSE5. Can I safely downgrade to an official ATT OREO firmeware, ie. G950USQS5CRL1 or G950USQS3CRE2 using ODIN?

The FW installed successfully and I'm now successully back on Oreo!

On a side note, when I initially completed setup, I got a notice that a new security update was being downloaded. I didn't want any updates, so I did a factory reset again.

When it rebooted and started setup all over again and prompted me to setup wifi, I put my wifi password, clicked next and after it connected, I immediately disconnected the ethernet cable from my modem to my router. So my phone is still connected to my wifi router, but it can't get to the internet. It wouldn't continue the setup, but I clicked back on the setup screen, unchecked wifi, then it used LTE instead to continue the setup but it did not check for any updates. Once setup was complete, I disabled auto-update from developer options, and also from:

Settings -> Lock Screen and Security -> Other Security Settings -> Security Policy Updates -> Auto Update

Then I re-enabled wifi and I have not gotten any notification about a new update and it's been over an hour. Hopefully there'll be no forced update.

So far, there's no battery drain. Been on the device for over an hour messing with settings, etc, and it only went down 2%. Really happy to be back on oreo!

Hey guys, my RMM prenormal lock finally cleared so I flashed TWRP and installed no-verity and RMM State bypass v3. I copied Smali patch files for mock locations.

Now my phone is acting up. Specifically, logging in to anything seems to struggle severely. My internet speeds are good and solid. But for example, I wiped data and re set up my phone. When searching for latest software during setup it took ages. When logging into my Google account or adding other Google accounts it hangs or takes forever. Logging into Pokemon Go takes multiple attempts.

I'm sure no one can explain this odd behavior, so I want to flash stock again.

If I flash stock including BL, AP, CSC (and I can't remember the other file) via Odin. Will I trip RMM prenormal and/or wiped TWRP?
