[Samsung Galaxy S8 Questions and Answers] GOMiCHO:
I tried that, but it works better when I just clear the Ram/Cache. Which makes me believe this is a separate issue, more software than hardware.
[Samsung Galaxy S8 Questions and Answers] d33dvb:
It still happens after a cache clear, and clearly if you bang on the phone and a speaker stops or starts playing, thats a hardware issue. There is no software that would do this.
[Samsung Galaxy S8 Questions and Answers] GOMiCHO:
I believe it's both a software and hardware issue depending on the phone you got.

I really wish Samsung would do more to solve this issue.
[Samsung Galaxy S8 Questions and Answers] GOMiCHO:
I just found the problem to my issue.

It was a software issue, Facebook Chat Heads was interrupting the audio and video functionality.

I disabled it, a week has passed and the problem has disappeared.
[Samsung Galaxy S8 Questions and Answers] imax1995:
And why when audio go off and i press the back of phone audio come on again? Not possible only software issue is hardware sure

I like the clean appearance and the smooth responsiveness, I used the AT&T firmware and I used PDP to disable a ****load of bloat, but nothing like this smooth.

not to mention I'm getting updates, which I'm more happy about.

this is really nice to have.

Please help me understand

I see some forums on this site that says, " G930UUEU2APEH flashes to g930a" then you have this post that says G930U firmware on SM-G930A. It seems as if one is saying to take the G930U and go to G930A and the other saying G930A and go to G930U. I thought the advantage is to go to the U and get off the A. Please confirm if this is the case. Granted then if this is the case... then, what are the advantages of going to the U? From what I understand it gets rid of the bloatware, and makes it so you can tether?

Also once I go, are there any negative reasons for me not to go from A to U?

Does this give me the current version of Nougat?

Do I get the upgrades from AT&T to keep up with future version of Nougat?

Also before proceeding to the U version MUST I first ROOT my phone?

Also MUST my phone be UNLOCKED?

Thanks in advance,

Hello about to get a s7 edge from craigslist mint condition for $150 and haven't used sammy phones in a great while. I have No idea what update it last had as of yet.( till I buy it tomorrow morning. Now does it matter what update the device is running to do this? And after its done can I root the device not sure if I will be doing that as the phone will be de-Bloated after the U firmware but just in case I want root based pop up-blockers.

Just use the files provided by the OP, and do ALL the OTA updates to get to Oreo.

The G930U Odin Oreo files for some reason will not flash straight to the G930AZ.

Got an S7 G930A as a backup phone today and followed the instructions in the OP with success.

I know that some people reported issues using updated files for Oreo, thus I went the OP route. BE AWARE, that firmware is from early 2017 and OTA updates are taking FOREVER. I'm in hour #2 and my phone is updated to August 2017. Oreo came in August 2018. You'll need multiple hours before you're all caught up.

Signal loss

Since I flashed my AT&T G930A to G930U my signal rarely goes above one bar.... I haven't noticed any actual issues other than that, but I would think that my signal should be stronger. Anyone else experiencing issues like this or is there something I can do other than reverting to stock AT&T bloat?

Whenever I flash any firmware for the 930U it flashes to m 930A just fine but it always screws up my display. It displays the first Samsung Logo fine, but from then onwards the screen is distorted and only uses the top half of my screen. Flash back to a stock 930A firmware and screen works perfectly fine.

I flashed with PrinceComsy and with 3.13.1 Patched. I also did factory reset and wiped cache but still nothing. I have tried many combinations (well over 15) and each and every time is gives me a messed up screen. Totally stumped as can't seem to find any other cases like mine via a google search.

Hello,

I just switched from AT&T to T-Mobile and I would like to get wifi calling on T-Mobile. I believe that the U firmware will work.

I tried flashing the U version and I keep getting the SHA256 error using the information on post 1.

I am currently on the latest android 8 Baseband G930AUCS8CRJ2 Oct 1, 2018 Security patch

This is the error I get

I tried the Odin3_v3.13.1_3B_PatcheD and Odin3_v3.12_PrinceComsy

Both of these Odlin's caused a bootloop and said invalid Dev Type on the S7

The only way I was able to fix the bootloop is downloading the same baseband version and flashed it with V3.13.1

I would like to use the U firmware or go to T-Mobile if wifi calling does not work on the U Firmware.

Any help would be much appreciated

Thank You

Small success report for future lurkers.

Was on AT&T firmware Marshmallow 6.0.1, flashed through patched Odin (princecomsy's) with OEM Unlock enabled. Used Windows 10.

Initially Odin got stuck at "Setup connection..." stage but I resolved that by disabling antivirus (Avast), using factory Samsung usb cable, running Odin with admin rights, rebooting PC and the phone itself (right from the Download mode). Everything altogether.

OTA updates work fine.

EDIT: So far phone updated 3 times, now I am at the latest version of security patch and firmware!

Everything went smooth and so far, did not noticed any

Only pls be informed that while as 930A had all languages, the rom i flashed it has certain basic languages only.

I have received an update via OTA few days ago , the G930UUES8CSA1 and i am in Greece.

After flashing and setup the phone, please make following setting to counterfight the reported and experienced battery drain:

1. Clear data from google services

2. Force stop chrome , facebook

3. Smart alert off

4. In oreo restrict background usage of android system

- downloaded android Oreo rom from here: https://samfrew.com/download/Galaxy__S7__/kpns/ATT/G930UUES8CRK2/G930UOYM8CRK2/

With the patched Odin(Above- other will not work), flashed the above mentioned rom to the phone.

After flashing and phone setup, make the settings on the phone to counterfight battery drain, as in my previous posts yesterday.

Please proceed with exact instructions for flashing with Odin ( Can be found with search in this forum or Google "Odin flashing instructions").
