Amazon Fire Tablet is a budget device with good quality.

But sometimes you may feel uncomfortable with the Amazon Appstore and the default Fire Launcher. And you want to replace them.
So here is the way to do.

1. Preparation

1.1 Install ADB on your PC

If you are an Android developer, you must be familiar with ADB (Android Debug Bridge) and have it installed on your PC.
If not, please check this link to see how to install it on your PC.

1.2 Enable USB debugging

First, enable Developer options on your Amazon Fire Tablet.
Open Settings → Device Options → About Fire Tablet.
Tap Serial Number 7 times.
After the first few taps, you should see the steps counting down until you unlock the developer options.
Once activated, you will see a message that reads, “You are now a developer!”

Second, enable USB debugging.
Open Settings → Device Options → Developer Options. Find the line USB debugging and turn the toogle on.

2. Install Google Play Store.

2.1 Check your Fire OS version

Open Settings → Device Options → System Updates.
You will see the text that reads, “Your device is running Fire OS x.x.x.x”.

2.2 Download Google Play Store APK

Different Fire OS version requires different APK, so choose the files based on your Fire OS version.

3. Replace default Fire Launcher

3.1 Install another Launcher app

There are many Launcher apps on Play Store. Try to download some and find the one suitable for you.
I’m using Microsoft Launcher and feel very comfortable with it.

3.2 Disable default Fire Launcher

Run the following command

adb shell pm disable-user com.amazon.firelauncher

It will disable Fire Launcher.
Now when you press Home button, your new Launcher will becomes a default one.

4. Disable other unused Amazon apps

4.1 Remove Ads when screen lock

Use the same command to disable any Amazon app you don’t want to use

For example, disable Amazon ads (the ads you see everytime you turn off and turn on the screen)

adb shell pm disable-user com.amazon.kindle.kso
