You cannot find betas on sammobile. The letter Z is only for beta versions.

Maybe next week beta program for Germany opens and then it can be installed on CSK4.

Is anyone having issues with spotify on the new beta? I seem to be the only one - it launches and then just quits.

Tried everything to fix it - permissions, clear cache / app data , older versions. Even tried the beta, same result.

Is there anh way to debug it?
[Samsung Galaxy S9+ Guides, News, & Discussion] Leon:
I don't have a problem with Spotify. Did you check battery optimizations for the app?
[Samsung Galaxy S9+ Guides, News, & Discussion] KeTuRr74:
It's working fine for me, i have only clean flashed the beta at the beginning that's all i did.

Yesterday I received a message that Google Pay is not working on my phone anymore because I have a modified, unsupported or rooted ROM :(

Seems that google don´t accept the Beta version ...But no big deal for me.
[Samsung Galaxy S9+ Guides, News, & Discussion] maik005:
Same as every year.

Beta firmware is never certified by Google.
[Samsung Galaxy S9+ Guides, News, & Discussion] Kruk07:
Yeah same hear. I read your post as Google Play but you are talking about Pay.
[Samsung Galaxy S9+ Guides, News, & Discussion] b0uncyfr0:
Yes, I've disabled it from sleeping.

Not for me, it just crashes and ive done literally everything i can think of:

1) Clear cache/app data , uninstall and reinstall (normal version)

2) Same above with the beta version.

3) Removed the spotify folder on internal and external memory

4) Removed sim and SD card

5) Tried mobile data and Wifi

6) Allowed all permission's in Android

7) Allowed all notification's in Android

8) Done a 'clean' install.

9) Tried a boatload of older versions online.

Still the same result... im at a loss here guys. Is there any way to enable debugging for one app somehow? Ive posted on the spotify community forums and it seems no-one knows what's wrong.
[Samsung Galaxy S9+ Guides, News, & Discussion] KeTuRr74:
You should try to grab a logcat it should help us to find out your issue.

Still possible to sign up for beta? I'm on dbt but found an older UK sim, maybe i flash the btu now and sign up officially.

Thx
[Samsung Galaxy S9+ Guides, News, & Discussion] maik005:
should be.

But load the XEU firmware.

As you will most likely be on XEU instead of BTU with that SIM.

Also note, that a factory reset is a must to change the CSC.
[Samsung Galaxy S9+ Guides, News, & Discussion] eddix1:
Yes i know, wanted to do that anyway. But why xeu? Isn't it practically the same? By the way, its a prepaid card by giffgaff.
[Samsung Galaxy S9+ Guides, News, & Discussion] Leon:
I didn't flash anything before the beta. Just formated with UK sim card and my CSC changed.
[Samsung Galaxy S9+ Guides, News, & Discussion] maik005:
yes, both the same

---------- Post added at 14:32 ---------- Previous post was at 14:31 ----------

but...

You need G965FXXU7CSK1/G965FOXM7CSJ5/G965FXXU7CSJ5

for beta to be installed and be able to register for beta.
[Samsung Galaxy S9+ Guides, News, & Discussion] Mr.Januzi:
Yes, If you are on DBT you probably are on CSK4.

Flash XEU or BTU CSK1 and you're good to go.
[Samsung Galaxy S9+ Guides, News, & Discussion] Leon:
Yes, correct.
[Samsung Galaxy S9+ Guides, News, & Discussion] Laclevuinhon:
my S9+ was rooted, can it update beta???
[Samsung Galaxy S9+ Guides, News, & Discussion] amakuramio:
can I flash beta zip with twrp? will my data be wiped? can I flash the twrp / rmm fix with it?
[Samsung Galaxy S9+ Guides, News, & Discussion] Mr.Januzi:
You can, but you MUST be on stock. Unroot your phone, flash stock BTU/XEU CSK1 and then sideload the beta.
[Samsung Galaxy S9+ Guides, News, & Discussion] KeTuRr74:
No you cant, you have to be on stock rom and stock recovery
[Samsung Galaxy S9+ Guides, News, & Discussion] galaxy mini:
I have installed beta too, special thx to [MENTION=5519079]leon.[/MENTION]

Also i "rooted" beta, root is also displayed but iam not able to debload and to erase any system apps. Anyone else got the problem??

Cheers.

-------------
[Samsung Galaxy S9+ Guides, News, & Discussion] amakuramio:
maybe someone can backup system only and we can restore it so we can install without wipe

and a custom zip to flash the other partitions

---------- Post added at 01:33 PM ---------- Previous post was at 01:22 PM ----------

so every update means wipe because have to install twrp and a fix
[Samsung Galaxy S9+ Guides, News, & Discussion] galaxy mini:
You can install without wipe

- flash stock rom via odin

- flash update.zip via stock recovery

of course you lose root and twrp,

anyway root doesnt seems to be working even if device says yes rooted, cant edit anything in root direction on beta,

so for now better keep beta unrooted.

Renamed .bin file to update.zip,moved it to sd card.

"couldn't mount sd card"

Mount sd card through adb ?

I did not try to mount it through adb.

Maybe somebody can try to do this before side loading the update.zip

Edit : also on beta 2 :

"failed to mount /sd card " in recovery mode .
[Samsung Galaxy S9+ Guides, News, & Discussion] Mr.Januzi:
Read the 1st page on how to flash via adb.
[Samsung Galaxy S9+ Guides, News, & Discussion] Leon:
Okay, I have to say I'm a little bit disappointed. I thought there will be new features or extras. I yet didn't browse the phone to see but by the changelog... It seems like from now on will be an only bug fixing and by judging again, the changelog which is not very big I think the stable version is near. I think Samsung keeps the new features and stuff for the S10 family, which is logical but I don't like it. I kinda expected to see Bixby routines, live focus video and AR Doodles. I probably will just check them and won't use them again but would be nice to have it though. Well, I guess this is it, Samsung want of us to buy newer devices. But this ain't gonna happen for me till I see what will be S11.
[Samsung Galaxy S9+ Guides, News, & Discussion] Skape_4:
update to beta 2 through recovery is working for me
[Samsung Galaxy S9+ Guides, News, & Discussion] brouwerchris:
Re-read the first sentence of my post.

I updated from beta1 to beta 2 by side loading through adb.

Like on beta 1 it is impossible in beta 2 to update from sd card in recovery mode.

Unless we find out how to mount sd card through adb ,it will be impossible to update from beta2 to beta 3 by updating from the sd card.
[Samsung Galaxy S9+ Guides, News, & Discussion] LiNe1771:

They are testing on the german unlocked server the Android 10 firmware as well as on the korean and us model server.

Beta is coming soon!
[Samsung Galaxy S9+ Guides, News, & Discussion] Mehdi0507:
Right now this is being tested on the DBT server for the S9+.

In the last couple of days there are frequently new Android 10 builds showing up. Same goes for the Korean model and the US unlocked model.

Plans are which I have from an insider source at Samsung that they are planning on releasing the stable version for the S9 in January 2020 which would be really fast for Samsung.

For the S10 and Note 10 series they want to rel EW as it in December.

My guess is we will see the S9 getting the beta around November maybe early November or so.

It's not officially stated if the S9 and S9+ or Note 9 will get a Beta program though. Would make sense as last year the S8 and Note 8 got in and even some A series phones. Maybe Samsung Discovered through last year thanks to good interest and input that with more beta programs for more devices they can fix bugs faster and release the sable version quicker.

[Samsung Galaxy S9+ Guides, News, & Discussion] Leon:
Sadly, no. The last news about it was for Note 9, which we already know would get it. I'm secretly hoping we will get it before the end of this month.

I also received my sim card from the UK, and I'm sure on 99% I will be able to join in the beta but probably won't be able to share the zip. I talked with one of the mods here and he shared one way and I try to pull normal OTA and it didn't work out. So I guess it won't work also when the beta came out. I hope someone else is more skilled than me with those things and to share the zip file with others.

As far as I remember, probably you can flash via Odin the official build when it is ready. If you start to sideload the builds you will need to do it till the last one.

I have a used, US Unlocked S9 with Verizon service.

I DLed the Samsung Members app in hopes of being able to get the One UI 2 Beta when available.

While I've been checking the app for the beta, I found that I cannot register my S9 with Samsung via the Members app, because it had already been registered. Likely by the original owner.

Also, the Members app reports that the warranty for this S9 expired in September.

Will any of these prevent me from receiving the Beta notification, when available?
