GalaxyBudsLive Disassembly Writeup
Analysis of the unreleased Galaxy Buds Live (aka Neobeans) plugin app for Android (as of 7/24/2020; expected release date: 5/8/2020)
Introduction
This repository contains all information I was able to find while searching through the Galaxy Buds Live plugin app for Android. I'll try to document my findings in this repository.
This is the API I accessed in order to get their pre-release APK: https://vas.samsungapps.com/stub/stubDownload.as?appId=com.samsung.accessory.neobeanmgr&deviceId=SM-G950F&mcc=262&mnc=03&csc=DBT&sdkVer=28&pd=0&systemId=0000000000000&callerId=com.samsung.android.app.watchmanager&abiType=64&extuk=000000000000000

Looseness detection
The Buds Live can detect if they are not properly inserted in your ears. If one bud doesn't not fit correctly it will show a red border around it in the app (displayed in one of the tip cards, not on the battery card):

New Hardware
Some parts of the debugging mode within the Buds Live refer to a gyroscope and to a sensor called "Vpu
" in both earpieces. VPU is an abbreviation for "Voice Pickup (Bone) Sensor" which enhances voice recording especially for calls by processing your bone vibration (afaik, the buds(+) had something similar as well) and can pickup voice wake-up commands. This new sensor is used with the new Voice Wakeup Feature!
The gyroscope is probably used for the looseness detection.

Ambient sound?
Apart from the gaming mode entry in the Labs screen, there's also a new interesting option called "Relieve pressure with ambient sound" (aka PASSTHROUGH
):
According to its description:
"This can prevent a feeling of stuffiness or compression when you're not using active noise canceling."
This sounds like a stripped down/recycled ambient sound feature...

Voice wake-up
In the advanced screen, we have a new feature called "Voice wake-up". It can be used to activate Bixby using "Hey Bixby" via the Buds Live without pressing any button on the buds. This is accomplished thanks to the new voice activation sensor (VPU).
However, this is Samsung-only since it only works with Bixby.

You can call Bixby by saying “%s” while wearing your earbuds.

Bixby
You can enable/disable ANC by Voice command but other than that, they haven't added anything now to it. No changes for bixby routines at all.

Find my mobile
Interestingly, the app refers to the FMM API (Find my mobile, NOT Find my gear). It may allow users, to let the Buds ring using the Find my mobile website/app and to retrace their steps using the phone's GPS if you lost your Buds Live or to display the GPS location when they were last seen by the Android device. This is just a guess though. (And since it relies on the "Find my mobile service" (com.samsung.android.fmm), it would be an Samsung-only feature)

Analytics
Just like the Buds and Buds+ app, this one is littered with usage analytics as well. Every now and then, the Buds send a usage report to the host device.
This includes data like: Single/double/triple tap count, tap-and-hold count, playback duration, wearing duration, ANC duration, low battery alert count, firmware error count, and much more.

Debug Menu
The Buds Live get a hidden debug menu as well. It'll work the same way the one for the Buds+ did and has the same features. Check my reddit post (includes instructions) about this: https://www.reddit.com/r/galaxybuds/comments/hjgfaf/galaxy_buds_i_found_a_new_debug_menu/
