How to Use ADB and Other Advanced Diagnostic Tools for Android

Android devices offer a high level of customization and control, especially for power users and developers. However, diagnosing and troubleshooting issues on Android can be challenging without the right tools. Phone diagnostic software and advanced debugging tools like ADB (Android Debug Bridge) play a crucial role in identifying and resolving system and hardware-related issues.

In this article, we will explore how to use ADB and other advanced diagnostic tools for Android, and when to seek professional help from Phone Clinix.

Why Use Advanced Diagnostic Tools for Android?

Most Android users rely on built-in diagnostics, such as battery usage stats or app crash reports. However, for deeper insights into system performance, hardware functionality, and debugging, advanced tools like ADB, Fastboot, and third-party phone diagnostic software are essential. These tools help in:

• Debugging performance issues

• Checking system logs and error reports

• Testing hardware components

• Managing and installing apps remotely

• Controlling device functions from a PC

Now, let’s dive into how to use these tools effectively.

Understanding ADB (Android Debug Bridge)

What is ADB?

ADB (Android Debug Bridge) is a command-line tool that allows users to communicate with an Android device from a computer. It enables:

• Installing and uninstalling apps

• Copying files between a computer and a device

• Running shell commands for debugging

• Capturing system logs

• Testing hardware and software performance

How to Set Up ADB on Your Computer

To use ADB, follow these steps:

1. Enable Developer Options on Your Android Device:

   • Go to Settings > About Phone

   • Tap Build Number seven times to enable Developer Mode

   • Navigate to Settings > Developer Options and enable USB Debugging

2. Download and Install ADB on Your Computer:

   • Download the ADB platform-tools from Google’s official site

   • Extract the files to a convenient location

3. Connect Your Device:

   • Plug your Android phone into the computer via USB

   • Open a command prompt or terminal and navigate to the ADB folder

   • Type:

     bash

     CopyEdit

     adb devices

   • If your device is detected, you are ready to use ADB commands

Common ADB Commands for Diagnostics

• Check Connected Devices:

  bash

  CopyEdit

  adb devices

  Lists all devices connected via ADB.

• View System Logs:

  bash

  CopyEdit

  adb logcat

  Displays real-time system logs to diagnose errors and crashes.

• Check CPU Usage:

  bash

  CopyEdit

  adb shell top -n 1

  Shows active processes and CPU usage.

• Check Battery Health:

  bash

  CopyEdit

  adb shell dumpsys battery

  Displays battery status, voltage, and temperature.

• Capture a Bug Report:

  bash

  CopyEdit

  adb bugreport report.zip

  Generates a comprehensive system log useful for debugging.

These commands help identify software and hardware-related issues before applying fixes.

Using Fastboot for Bootloader and Recovery Mode

Fastboot is another powerful tool used alongside ADB. It is primarily used for:

• Unlocking the bootloader

• Flashing firmware and custom ROMs

• Recovering bricked devices

Common Fastboot Commands

• Check Fastboot Connection:

  bash

  CopyEdit

  fastboot devices

• Unlock Bootloader (Warning: Erases Data):

  bash

  CopyEdit

  fastboot oem unlock

• Flash a Custom Recovery (e.g., TWRP):

  bash

  CopyEdit

  fastboot flash recovery recovery.img

Fastboot is useful when dealing with system-level issues that phone diagnostic software cannot fix.

Third-Party Phone Diagnostic Software

While ADB and Fastboot provide powerful command-line tools, many users prefer graphical phone diagnostic software for easier troubleshooting. Here are some of the best options:

1. Phone Doctor Plus

Best for: Hardware and sensor testing

• Tests touchscreen, gyroscope, accelerometer, and more

• Battery health and charging speed analysis

2. DevCheck

Best for: Monitoring CPU, GPU, and system performance

• Real-time monitoring of system resources

• Battery temperature and usage tracking

3. AccuBattery

Best for: Battery health and longevity

• Detects battery wear level

• Provides charging optimization recommendations

4. Phone Info+

Best for: Detailed hardware and software information

• Displays bootloader status and root access

• Provides firmware and sensor details

These tools complement ADB by providing an easy-to-use interface for diagnosing common issues.

How to Diagnose Common Android Issues with ADB and Diagnostic Tools

1. Phone Running Slow or Freezing

• Use adb shell top -n 1 to check CPU usage

• Identify apps consuming excessive resources and disable them

• Clear cache using adb shell pm clear <package_name>

2. Overheating Issues

• Use adb shell dumpsys battery to check temperature

• Identify background apps causing excessive CPU usage

• Reduce CPU stress using DevCheck

3. Battery Draining Quickly

• Use adb shell dumpsys batterystats to analyze power usage

• Uninstall power-hungry apps using adb uninstall <package_name>

• Use AccuBattery to optimize charging habits

4. Wi-Fi or Network Issues

• Check signal strength using adb shell dumpsys wifi

• Use Phone Info+ to analyze network performance

• Restart network settings using adb shell svc wifi disable && adb shell svc wifi enable

When to Seek Professional Help from Phone Clinix
