A Complete Guide to Android ADB Wireless Debugging

With the release of Android 11, Google integrated Android Debug Bridge (ADB) wireless debugging as a native feature within the operating system. This major update in ADB introduced a secure pairing mechanism that completely eliminates the need for an initial USB connection. This modern approach, fully integrated into both Android’s Developer Options and Android Studio, uses on-screen pairing codes or QR codes to establish a cryptographically secure connection, representing a significant improvement in both usability and security over the legacy method.

This was not an architectural overhaul, but rather an enhancement to the connection establishment and security protocol built upon the existing transport-agnostic foundation.

Although most developers and many Android users still use USB debugging, wireless debugging may sometimes be the easier solution, for example, when connecting to a Google TV Streamer or Chromecast with Google TV (the only USB port is occupied for power). Some Android TV boxes may not have an additional USB port as well.

This Android 101 guide explains how ADB works, what Android ADB wireless debugging is, the prerequisites for using Android Wireless Debugging, detailed steps for using Android Wireless Debugging, and how to use Android Wireless Debugging on older (pre-Android 11) devices.

This guide applies to almost all Android devices, Android phones, Android tablets, Android TV, Chromecast with Google TV, and Google TV Streamer.

What is Android ADB Wireless Debugging?

First, let’s recall the ADB Architecture.

The ADB system is composed of three distinct components that work in concert to facilitate communication and command execution.

  • The Client: This component resides on the host machine (the development workstation) and is invoked by the user through the adb command in a terminal or command prompt. The client is responsible for translating user-issued commands, such as adb install or adb shell, into the ADB protocol and sending them to the ADB server.
  • The Server: The server is a background process that runs on the host machine. When an ADB client is started for the first time, it checks for a running server process; if one is not found, it initiates one. The server binds to the local TCP port 5037 and acts as a central hub, managing communication between all running clients and the daemons on all connected devices (physical or emulated). Its role is to multiplex commands and responses, ensuring that requests from various clients are routed to the correct device daemon.
  • The Daemon (adbd): The daemon is a background process that runs with elevated permissions within the Android user space on the target device (i.e.,

Extra Dim in Android 12: The Definite Guide

How does Extra Dim in Android 12 work? How to customize and use Extra Dim?

Last updated on: , first published on: Leave a Comment

Extra Dim in Android 12: The Definite GuideExtra Dim is a less-known yet very useful new feature in Android 12.

It is not included in our top 12 new features in Android 12 because Extra Dim is a “niche” feature for very specific scenarios (if you often use the phone in a dark environment), not because it is not important.

Extra Dim is often misunderstood by even many professionals. Therefore, many users are confused the Extra Dim with the brightness control.

This Android 12 guide explains what the Extra Dim in Android 12 is, how it works, how to use it in Android 12, and corrects some common misunderstandings about Extra Dim in Android 12.

What is Extra Dim in Android 12?

Sometimes, you may feel the phone screen is too bright in a dark environment (e.g., in a theatre). However, the brightness level is already set to the minimum level or auto-brightness (adaptive brightness) is already on.

Basically, you are stuck on that uncomfortable brightness level.

Extra Dim, which was introduced in Android 12,  is designed to solve this issue for you. It can further reduce up to 50% of the brightness of the screen for you.

In Android 12, Google implemented Extra Dim as an accessibility feature to further reduce the “brightness” of the screen below the minimum level specified by the hardware vendor.

This may sound ridiculous. How can the brightness be lower than the minimum level specified by the hardware vendor?

So, here is the catch. When Extra Dim is activated,  the colour range will be reduced.

In other words, you get a dimmer screen at the price of the accuracy of the colours. Read on.

As this is a built-in accessibility feature in Android 12, none of the Android vendors has changed this feature.

In addition to the entry in the accessibility settings,  a quick setting button for Extra Dim can be found in most Android 12 phones (e.g., in Galaxy S22).

How does Extra Dim in Android 12 work?

To understand how Extra Dim works, we need to know a bit (just a bit) about the colour and brightness.

Each colour on the screen has a value. For example, if the screen can only display 256 colours (8bit; most smartphone screens actually can display 16,777,216 colours or 24bit), the black colour will have a value of 0, and the white 255. The colour range is then 0-255.… Read the rest

How to update to Android 12?

Everything you need to know on getting the Android 12 update

Last updated on: , first published on: 2 Comments

How to update to Android 12?Android 12 was officially released on October 4, 2021. But many Android device owners are still waiting for the update and want to know how to update to Android 12.

This Android 12 guide explains why some Android devices got the Android 12 update already, some are still waiting for it, and some will never get it. The guide also shows how to check the Android 12 update for your device and how to update your phone (or tablet) to Android 12.

Why am I still waiting for the Android 12 update?

When Android 12 (Snow Cone) was released to the public on October 4, 2021, these were only the “core” of the new Android OS.

Unlike Windows, Android releases the source code, not the executable. The drivers for the components of your Android device, e.g., the touchscreen, the sensors, the modem, are usually not included.

So, before the new Android OS code is compiled with the drivers for the components, the source code of Android 12 is actually useless for your phone.

To make it worse, you have to wait for the manufacturer of your Android device to build the executable because most of these drivers are proprietary. You cannot do it by yourself.

So, it will take the manufacturer some time to test and build the new “firmware” for your phone. In fact, Google released the Android 12 build for Pixel phones on October 19, 2021. These are the first Android phones with Android 12 updates.

Some big manufacturers, like Samsung, are deeply involved in beta testing and usually have more resources to put everything together to roll out the Android 12 update. So, you will get the Android 12 update for your device within 2-3 months. Older devices may also get the Android 12 update, although the update usually comes later than newer devices.

Some middle-tier Android vendors, like Motorola (or its parent company Lenovo), are reluctant to invest resources on sold devices. They care more about getting quick money (sell new devices). They may roll out the Android update on a few latest models.

Smaller Android vendors may not have enough resources to build a new OS for older devices, and therefore, these devices will NEVER get the Android 12 update.

How about the unofficial Android 12 update?

Building the latest Android OS for older devices normally requires even more resources than for newer devices due to some compatibility (with some new features) issues of “a few” old components used in the older devices.… Read the rest

How to use notification history and notification logs in Android 11?

You can use notification history in Android 11 and notification log to check dismissed notifications.

Last updated on: , first published on: Leave a Comment

Android 11 Notification iconWith the Android 11 update, a new feature, notification history, has been introduced, allowing users to track the notifications on their devices even after being dismissed.

In addition to the notification history introduced in Android 11, stock Android also allows you to access full notification logs through a Settings widget.  It is a somewhat hidden feature.

This Android 11 guide will explain what the Android 11 notification history is, the difference between notification history and notification log,  how to use it and answer some questions you may have about the notification history.

What is the Android 11 notification history?

Since the feature of snoozing notifications was introduced in Android Oreo(Android 8), it has allowed users to organise their notifications on their devices and prevent notifications from cluttering. However, there are times when you may accidentally dismiss an important notification before checking it out. Therefore you may want to check the notification history or the full notification logs.

The Android 11 notification history is essentially a feature which allows users to track their notifications and view all previously dismissed notifications on their devices.

This feature is useful for decluttering the notification panel under the quick settings menu.

Users can always refer to the notifications history to look up some important notification that may have been missed.

In the notification history, the time and date at which the notification was sent are also recorded so users can view time-limited notifications that may have been missed.

Difference between notification history and notification log

Notification history and the notification logs were designed for different purposes.

  • Notification history is only available in Android 11 (and later). Notification log is available through a Settings widget from at least Android Gingerbread (Android 2.3).
  • Notification history only offers notifications in the past 24 hours.  Notification log includes notifications since the last reboot.
  • Notification history only shows notifications that have been shown in the notification panel. Notification log has all notifications including the hidden (not shown in notification panel) notifications.
  • Tapping any notifications in the notification history will open the corresponding app. Tapping and holding (long tapping) the notification will direct you to notification settings for the corresponding app. But if you tap notifications in notification log, you may get different results in different versions of Android. In Android 11, it directs you to the notification settings for the corresponding app. The long-tapping and tapping gestures work identically in the notification log page.

How to use native screen recorder in Android 11?

You can record whatever on the phone screen and share it as a video.

Last updated on: , first published on: Leave a Comment

Android 11 screen recorderAndroid 11 has finally included a native screen recorder.

Although some Android phones such as the Samsung Galaxy s10 already have a native screen recorder, it was only available to Samsung phones. With the Android 11 native screen recorder, Android devices are now able to take screen recordings without the use of third-party apps.

Read on to learn more about this feature, how to use it and some questions you may have about it.

What is native screen record in Android 11?

As seen by its name, this feature allows users to take a recording of their device screens without using an application.

Although there are many third-party apps which offer decent screen recorders for Android, the new native screen recorder in Android 11 reduces the hassle for users when they want to take a screen recording.

Since it is a native screen recorder, the recordings can be saved and directly backed-up to the Google Photos app. This allows users to be able to view and edit their recordings through the Google Photos app on different devices.

However, do note that as the screen recorder takes a video of what is displayed on the screen when it’s turned on, sensitive information such as passwords and usernames will be captured in the recording. These can be edited out or censored after the recording is saved using video editing apps or through the Google Photos app.

Anyway, now you are not limited by the static screenshots when you want to share the screen. You can share it as a live video with sounds.

How to use native screen record in Android 11?

To allow for easy access to the Android 11 screen recorder, users are able to access and use the feature through the quick settings menu. The following steps will show you how to use native screen record in Android 11.

Step 1: Access the quick setting menu

To access the quick settings menu, pull down twice from the top of the screen (or status bar if not in the immersive mode).

Scroll through the quick settings menu until you see the screen record icon. Tap on it to begin recording.

If you cannot find the button, you can tap the Pencil icon to add it.

Step 2: Begin recording

After tapping on the screen record icon, a pop-up for screen recorder settings will appear where you can adjust the settings for the screen recorder.… Read the rest

How To Use Live Caption in Android 10 and Android 11

Last updated on: , first published on: 3 Comments

Android Live Caption

Android 10 introduced the Live Caption feature, initially for selected Pixel phones, to automatically caption any audio being played.  Later, most Android vendors implemented it in Android 10 phones (e.g., Samsung Galaxy S20 and Galaxy Note 20).  Google further improved this feature in Android 11.

This Android 11 guide explains what Live Caption is, when you need to use it, how to use it, and how to customise it in Android 11 and Android 10 phones.

What is Live Caption?

Live Caption is a new feature that has been added to phones with Android 10 and up.

When the feature is enabled, the phone automatically detects audio being played and captions them on the phone in real-time. You can use the Live Caption even if the phones audio is being muted.

Live Caption generates real-time caption according to the audio that’s being played. The feature is supported by most Andriod apps but may be unavailable for some media and calling apps.

When to use Live Caption?

Live Caption in Android 10 and Android 11 can be used to caption the audio from the following such as:

  • Audio messages
  • Phone calls
  • Videos
  • Podcasts
  • Recordings

Anyway, you can use this feature to caption most audios on Android 10 and Android 11.

How to turn on Live captions?

By default, Live Caption is not enabled in most Android phones.  You can turn on (and turn off)  it at any time. The captions will only show when speech is detected.

Live Captions in Android 10 and Android 11 can be turned on through 2 ways:

  1. Using Android Settings;
  2. Using the volume button.

Top 11 new features of Android 11

The best Android 11 new features explained

Last updated on: , first published on: Leave a Comment

Top 11 new features of Android 11Google released Android 11 on September 8, 2020, with many exciting new features and improvements.

Supported Pixel phones including Pixel 4, Pixel 4 XL, Pixel 4a, Pixel 3, Pixel 3 XL, Pixel 3a, Pixel 2 and Pixel 2 XL, all received the Android 11 update immediately after the release.  The first generation Pixel and Pixel XL stopped at Android 10 and did not receive the Android 11 update.

Other Android manufacturers will roll out their Android 11 update based on their own schedule. Some manufacturers may release the Android 11 update in November to December. But for the majority of owners of non -Pixel phones, very likely,  they will receive the Android 11 update from early 2021.

This Android 11 guide explains the top 11 new features of Android 11: conversations in one place, notification history, bubbles, native screen recorder, seamless media control, smart device controls, one-time permissions and auto-reset permissions, dark theme scheduling, security updates via Play Store, smart Reply, app suggestions, and smart folders for Pixel phones, and wireless Android Auto.

Of course, there is an Android 11 Easter egg: Neko Cat game.

Conversations in one place: the most useful new features of Android 11

In Android 11, all notifications from messaging apps now are grouped as conversions in the notification panel.  You can not only read the incoming new messages but also directly reply in the notification panel.

And it works for all messaging apps.

On the lock screen, you can even choose to show priority conversations from specific contacts or individual chat threads.

Most Android 11 users will admit the conversation is one of the best new features of Android 11.

Notification history

Very often, we dismiss some notifications without checking them. But sometimes, you may realize the notification may be important.

Prior to Android 11, you cannot access notification history unless you use some third-party apps.

Now, you can enable notification history in Android 11 (Settings —Apps & notifications — Notifications — Notification history) to check snoozed and dismissed notifications.

Bubbles

Bubbles are just a minimized pop-up view of a chat.

Android 11 lets you pin conversations anywhere on the screen. Because the chat bubbles appear on top of other apps and screens, you can always check and participate in the conversation when using other apps.

By default, chat bubbles and notification history are not enabled in Android 11. You need to enable bubbles in Settings — Apps & notifications —Notifications  —Bubbles — Allow apps to show bubbles.… Read the rest
