If you’re switching Android smartphones and tablets and using the same Google account for each of them, you’ll notice that the Google Play Store shows them when you want to install apps from your computer. This can sometimes get confusing. Here’s how to remove old devices from the list.
If the list looks like the one in the image above and you’re not using all of those devices, you’ll want to shed the old ones from the list. The process is easy. And even though you can’t remove a device altogether, you can at least remove it from the list.
Remove Android Devices from Google Play Store List
Log in to the Google Play Store and click Settings (gear icon) on the top right side of the page or just click this link.
On the next page, click the Settings tab to see the list of devices. Just uncheck the devices you don’t want shown in the devices list anymore when installing apps.
Note: Here you can rename your devices by clicking the Edit link on the right end of each device’s line, type in a new one, and hit Enter. You can also change your email preferences.
