This article explains how to access iCloud photos, email, calendars, and contacts from an Android device.
How to Access Apple iCloud from Android
To access your iCloud Photos on an Android, sign in to your account through a mobile browser. Tap Photos and you’ll see all the images you have stored in iCloud.
You can also create iCloud links to share photos and videos, view albums, and access account settings.
Another option, if you still have your iPhone, is to download the Google Photos app for iOS and sync your photos there. You can work with your photos there just as you would with iCloud Photos.
