Overview
- Compact alerts can show a paperclip indicator, and expanded notifications add a pill that identifies the attachment type such as an image or PDF.
- For many users, expanding the alert displays thumbnails for images and a pill showing PDF type and filename, offering quicker triage at a glance.
- When an attachment is detected, the preview can replace the usual email body snippet, requiring opening Gmail to read the message text.
- The rollout remains slow and selective with no formal announcement from Google, first spotted by 9to5Google and corroborated by Droid Life, Android Central, Times Now, and SamMobile.
- Behavior varies by account, with some reporters unable to replicate full previews, indicating a staged server-side switch rather than an app update.
