Once you’ve installed all four apps, it’s time to restart your Fire tablet. Press the power button until the power menu appears, then press restart.
4. Sign in with your Google account
Once your Fire tablet restarts, you should be able to open the Google Play Store, sign in with your Google account, and start downloading apps. Again, not everything works, but there are certainly more choices than the Amazon app store.
Tips & Troubleshooting
If you want a more standard Android experience, you can install a custom launcher that lets you hide all the Amazon apps you don’t need. I like New launcherbut there are many others available.
Assuming you’ve finished installing APKs from unknown sources, it’s a good idea to go back and disable this option. It’s in Settings > Security and privacy. Switch off Applications from unknown sources option. This will prevent you from accidentally downloading malicious software.
If you’re having trouble installing apps from the Play Store, try clearing app data. Head to Settings > Applications and notifications > Manage all applications. Browse this list and find the Play Store. Tap to change settings. The first step is to touch Forced stop to close the Play Store. Then click storagethen Clear Data (or Clear storage, depending on which version of Fire OS you’re running). Once that’s done, restart your device and try signing into the Play Store again.
If that doesn’t work, you can do a factory reset and start over. However, keep in mind that a factory reset will delete all of your data and files, not just the Google Play store, so make sure you have a good backup before trying this.
If you’re comfortable using the command line, you can go even further and uninstall the Amazon software you don’t need. To do this, you need to install a program called Android Debug Bridge. This is a Google developer tool for interacting with an Android tablet from your PC, hence the name “Bridge”. You can download the latest version Debugging Bridge by Google. Once installed, you can run Android commands on your Fire tablet from your PC’s terminal.
