The Samsung S7 Android device with a build fingerprint of samsung/heroltexx/herolte:8.0.0/R16NW/G930FXXS4ESC3:user/release-keys contains a pre-installed app with a package name of com.samsung.android.themecenter app (versionCode=7000000, versionName=7.0.0.0) that allows other pre-installed apps to perform app installation via an accessible app component. This capability can be accessed by any pre-installed app on the device which can obtain signatureOrSystem permissions that are required by other other pre-installed apps that exported their capabilities to other pre-installed app.

Samsung Galaxy S10 and Note10 devices allow unlock operations via unregistered fingerprints in certain situations involving a third-party screen protector.
On certain Samsung P(9.0) phones, an attacker with physical access can start a TCP Dump capture without the user's knowledge. This feature of the Service Mode application is available after entering the *#9900# check code, but is protected by an OTP password. However, this password is created locally and (due to mishandling of cryptography) can be obtained easily by reversing the password creation logic.
The Text-to-speech Engine (aka SamsungTTS) application before 3.0.02.7 and 3.0.00.101 for Android allows a local attacker to escalate privileges, e.g., to system privileges. The Samsung case ID is 101755.
Samsung Galaxy Apps before 4.4.01.7 allows modification of the hostname used for load balancing on installations of applications through a man-in-the-middle attack. An attacker may trick Galaxy Apps into using an arbitrary hostname for which the attacker can provide a valid SSL certificate, and emulate the API of the app store to modify existing apps at installation time. The specific flaw involves an HTTP method to obtain the load-balanced hostname that enforces SSL only after obtaining a hostname from the load balancer, and a missing app signature validation in the application XML. An attacker can exploit this vulnerability to achieve Remote Code Execution on the device. The Samsung ID is SVE-2018-12071.
Xiaomi Mi 5s Plus devices allow attackers to trigger touchscreen anomalies via a radio signal between 198 kHz and 203 kHz, as demonstrated by a transmitter and antenna hidden just beneath the surface of a coffee-shop table, aka Ghost Touch.
