Android 12 Errors, Bugs, And Issues – A Full List

Android 12 Beta 4 has been deemed the first stable build by Google, but ultimately, it’s not the final product. It’s always wise to know with an unreleased operating system what its current issues are and whether you can deal with them or not. make sure to bookmark our Android hub for any guidance you may need with Google’s titanic operating system.

The best way to find bugs and issues with an operating system such as Android 12 is to release a Beta or Developer version, such as Android 12 Beta 4, for the masses to report back on what issues they’ve been having. It’s free quality assurance testing and some great publicity for Android 12 features.

For top unresolved bugs and errors, Google has its own Issue Tracker for Android 12 Beta 4 here. This is great for reporting undiscovered bugs, but here’s a list of known issues that are currently being worked on:

All apps

• In some scenarios, users of apps that have been granted the Display over other apps permission and render full-screen overlays might find touches blocked on Android 12 until the developer updates the app. Affected users can temporarily turn off the permission in Settings, which can always be accessed using the settings icon in the notification shade. If an app you use is affected by this issue, you can contact the app developer directly to let them know.
• When a user attempts to add another account to the device under Settings > Passwords & accounts, the UI turns black and the back button becomes unresponsive.

Google apps

• When connected to a Bluetooth headset, users running the beta version of the Phone app might experience a crash loop when trying to make a call. This issue is caused by the Phone app not having the required Nearby Devices’ permission. In addition, users can’t grant the Nearby Devices permission to the Phone app either from the Permissions screen in App info, or through the Permissions manager.
  To work around these issues, users can grant the Nearby Devices permissions to the Phone app using the following adb commands. If you need to set up adb first, see Connect to a device over Wi-Fi.

“adb shell pm grant com.google.android.dialer android.permission.BLUETOOTH_SCAN && adb shell pm grant com.google.android.dialer android.permission.BLUETOOTH_CONNECT && adb shell pm grant com.google.android.dialer android.permission.BLUETOOTH_ADVERTISE” 

• Users should also check the Play Store for any Phone by Google beta updates that are available to receive the latest fixes.
• In some cases after updating a device to Beta 4, Google Maps crashes whenever it is launched by a secondary user.

Android platform

• For devices with multiple users, in some cases after updating the device to Beta 4, the device crashes and reboots when trying to switch to a secondary user.

Android Studio and tools

• When installing an app that has a targetSdkVersion of “S” from Android Studio, developers might see the following error:

“Installation did not succeed. The application could not be installed: INSTALL_FAILED_VERIFICATION_FAILURE

List of apks:

[0] ‘…/build/outputs/apk/debug/app-debug.apk’

Installation failed due to: ‘null’”

• The likely cause is that one or more of the app’s activities, services, or broadcast receivers includes intent-filters, but does not explicitly set a value for android:exported. Android 12 requires setting an explicit value for this attribute on all <activity>, <service>, and <receiver> components that also have an <intent-filter> defined. For more information, see Safer exporting of components. Note: This issue is already solved in the latest release of Android Studio Arctic Fox. To get the latest fixes and enhancements when targeting Android 12, we recommend installing a preview version of Android Studio alongside your stable version.
• The latest preview version of the Android SDK Build Tools (31.0.0) is not compatible with Android Studio versions prior to Android Studio Arctic Fox.

Android Auto

• After a user receives the OTA from Android 11 to Android 12 Beta and using Wireless Android Auto, some users may encounter a crash with Android Auto when trying to establish a Bluetooth connection. We are looking into this and a fix will be made available in the next Android 12 Beta release.

Android TV

• Hotplugging the HDMI cable might cause video playback to fail on some display sinks.
• Android Google Home App (GHA) version 2.42.1.11 or above is required to perform the 2nd screen set up. Performing setup using the iOS app or by using the remote is intact.

The following applies to Android 12 Beta 3, although it’s always wise to run the latest build possible. This may differ with OEM preview programs.
