Meta has started rolling out Update 125 for the Ray-Ban Display smart glasses. These are the premium Ray-Ban glasses with the built-in display, separate from the regular camera-only Ray-Ban Meta glasses.
Neural Handwriting Is Now Available for Everyone
The main addition is Neural Handwriting, which is now available to all Ray-Ban Display owners worldwide on both iOS and Android. It was earlier limited to beta testing for WhatsApp and Messenger.
The feature works through the Neural Band that comes with the glasses. It uses sEMG sensors to read small finger and wrist movements. You can rest your hand on a desk, your palm, your thigh, or even your leg, then move your finger like you are writing. The glasses turn that into text.
It works across WhatsApp, Messenger, Instagram DMs, and native phone messaging apps. You can also search contacts, reply to notifications, and send quick messages without touching your phone.
Display Recording Comes to Ray-Ban Display

Meta has also added display recording. This records the in-lens display, the front camera view, and audio in one video file. It should help if you want to show someone exactly what you are seeing through the glasses.
Maps Get Full Walking Directions
Maps also gets better. The glasses now support richer search results, saved home and work locations, voice-guided navigation, and full walking directions. Walking directions are available across the US and in major cities like London, Paris, and Rome.
App Updates for WhatsApp, Instagram, and Facebook
There are a few app updates too. WhatsApp now supports group video calls and real-time captions during phone calls. Instagram gets smoother Reels playback and better DM navigation. Facebook gets widgets for birthdays and sports scores.
Third-Party Developer Access Opens Up
Meta is also opening the platform to developers. The new Device Access Toolkit SDK is available for iOS and Android, and WebApps built with HTML, CSS, and JavaScript can also run on the glasses after some optimization. Early experiments already include YouTube playback, grocery lists, transit tools, aviation references, and simple games.
Update 125 Rollout
Update 125 is rolling out over the air and should reach all Ray-Ban Display owners in the coming days. You can also check manually through the Meta View app.
