[amazon prime video] license_error on Android Oreo

Hi everyone, firstly i'm sorry for my bad english.
I have a problem with the amazon prime video app. I sign in with my credential, then when i choose a movie, i receive an error message: Video not available, License_error. The app in installed on my Nexus 5x with Android 8.1.
On my Nexus 7 tablet (Marshmallow) and Nexus 6 (Nougat) the app run perfectly with no problem. So I think it's an issue with Oreo. Somebody can suggests me a solution to this problem?
I tried clearing app cache, uninstalling it, and a factory reset of the phone. No solution.

Hi,
I have the same problem and I guess it's a DRM issue. My motherboard was replaced by LG after a boot loop issue. What about yours ?

Hi, LG replaced my motherboard too! Same bootloop issue. Can't be a coincidence

I think there is somewhere in the DRM manager a signature for the device hardware and the new motherboard is not known (because it's different from the original one, you cannot unlock the bootloader for example).
The logs when the error occurs :
AmazonVideo: Cannot get rights from MediaDrm without a keySetId, returning null rights.
AmazonVideo: Warning: DrmFramework.getRights for drmAssetId "CAESEKYUJ9/cR0EEvgvTa5ym/2EaBmFtYXabcdeflkOnBoUW4zOXhIUVFTK0M5TnJuS2IvWVE9PSxPU1pabcdef1M1bW05ZlBGTS82TEhnPT0qAabcdeF=" DrmScheme: WIDEVINE returned null

So you're telling me that I can not do anything about it? I can not contest anything with LG for this problem?

Amazon uses Widevine DRM wich does not support end users requests. Maybe Amazon has to contact them about this issue. I don't know if LG can do something on their side.
I just found some Netflix users had the same issue, but it was solved after the Oreo update.

I undestand. So the only thing I can do is waiting for an app update.
Thank you so much for the information

Fingerprint

After updated to Oreo , the finerprint sensor still doesnt work well on my xzs . Should i try software repair ? I just updated and format my phone . Will software repair solve the fingerprint issue ? Or it will be the same ? Coz i lazy to wait and perform the software repair again . When i unlocked my phone with fingerprint , i failed most of the time , i was prompted to unlock the phone with PIN instead . This is kinda annoying . I have this problem since Nougat ... Is it hardware faulty ? My finer isn't oily and the sensor isnt dirty either.

is this hardware problem ?

Need to downgrade s7 g930fd

Hello devs i need to downgrade s7 back to marshmallow.. is that possible by flashing m frimware ?
Anyone have tried downgrading back to Marshmallow after updating to dec security patches?

I've downgraded to MM from N a few times. Pretty simple, all you need to do is download the stock firmware from sammobile.com or updato.com and flash with Odin (both sites have a flash guide I believe).
Make sure you flash all 4 files.

Yeah bro??☺ successfully downgraded without any issues.. camera ,battery is far better in Marshmallow?

Bro.. fingerprint sensor is not working?.. while dailing *#0*# in sensor fingerprint it says initialisation failed..

I don't use the sensor so I never tested it during my roll backs. You flashed all 4 firmware files? BL, CP, CSC and AP?

Yeah ive flashed all 4.... fingerprint sensor is working only in nougat frimware..?

I know the bootloader differs in N to MM which impacts a few things but if you flashed all 4 it should be fine, I would suggesting trying to wipe cache/davlik but an Odin flash should have been a full wipe already.

Yeah..bro.. i hve cme back to n ..bzo of this issue

Is fingerprint wrng fr u?.. in mm

I don't have MM at the moment, it's been a couple months since I was doing my upgrades and roll backs

Hi all,
I need to downgrade a new g930fd (MFD 2018-01) as well to MM for xprivacy since I'm not one of the mass fools giving away all their accounts on their devices, everything on storage, phone numbers, IMEI, MAC address, etc. to every app that I need to run for my job, as well as every factory ROM and pre-installed app. Oh, I forgot to mention every app talking to like 5 or more mobile app tracking servers including graph.facebook.com!
Anyhow, I ran into the fingerprint sensor issue as well with downgrading to MM. It seems to be something to do with the S7's with a newer manufacture date since I have other older g930fd's I was able to downgrade and have the fingerprint sensor work fine.
It appears to be that the driver in Samsung MM ROMs isn't compatible with the newer fingerprint chips.
This is the only difference I could find in the sensor information:
Working Downgraded to MM Fingerprint Sensor
Flex ID 2291
Product ID 144
Sensor ID 4099
Non Working Downgraded to MM Fingerprint Sensor
Flex ID 295
Product ID 144
Sensor ID 4103
I'm guessing the fingerprint sensor drivers included in S7 MM firmware don't support the "Sensor ID 4103" chips yet. All we would have to do is move over the drivers to MM with root, but I have no idea how to do this.
Can anyone with ROM building experience that's migrated drivers help out here please?
Thanks!

Update:
It appears the "Version" displayed in *#0*# under FingerPrint test is actually the driver version since there is a separate FwVersion displayed when you hit SensorInfo.
From a shell,
ls /sys/module
Shows the fingerprint sensor as a kernel driver. It's the Egis ET320 Sensor.
So, sadly, apparently you can not use MM with a newer hardware revision of the ET320.
The only option would be to either find an older phone maybe someone could figure out how to get the newer driver out of the newer Samsung builds so we can have an external kernel module in /lib/modules/<kernel version>/extra
Samsung source code is freely downloadable here if anyone could please compile the ET320 driver into an externally loadable module and instruct on overriding...
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=g930f
Swapping the sensor out with an older version will not work since the fingerprint sensor is paired with a chip on the logic board as many who have tried to replace their home button have regrettably learned.

Update2:
I downloaded Nougot and MM Sources from Samsung and see that the fingerprint drivers have definitely been modified. There is a makefile for building the fingerprint driver, but I have no idea what's all involved with getting this going.
Anyone?

Can anyone help a brother out here?
What's the right thing to do - try to attempt to get just the driver compiled into a module that could possibly override the kernel module driver (if it's supported) and drop it in /lib/modules/<version>/extra or recompile the entire kernel with the newer drivers and figure out how to install it?

Auto Rotation not working

Hello,
my p20 is already on 8.1.0 and was working well since I got it.
Now, the function for auto rotation is not doing it's work. Yes, it did work well before.
I was wondering, if anyone has the same problem and if there is a solution for it?
I tried to turn off ne knuckle features. It wasn't the solution.
Thanks

No, thought there could be another solution. But it doesn't seem so..

I have the same issue on P20 lite, after the update the sensors doesn't work anymore.
I have a locked bootloader and tryng to roolback with a previose version, with dload metod, but non easy to find the correct verson due a huge firmaware for P20
I contact even the customer support and only thing that said to me: "Please try with a reset or use you warranty to change it" (for me it's the second phone with the same problem)

I have not seen biometiric firmware as separate flash-able peace, it is always in security patches .. If you did factory reset and problem is still there, i am afraid that you will need to contact Samsung ....
