Floating memory bubbles on the Samsung Galaxy Z Fold 4

The Samsung Galaxy Z Fold 4 runs Bubbles In Time's floating memory layer in full — and an early foldable that still makes memories feel theatrical. Here's the Samsung Galaxy Z Fold 4-specific picture: setup, behavior, and what to expect.

On this phone specifically

On the Samsung Galaxy Z Fold 4, One UI foldable exposes Android's standard 'display over other apps' permission during Bubbles In Time's first-run setup — grant it once and memory bubbles can drift over the home screen, messaging, and every app you use. Bubbles never steal focus from the keyboard or playback; they float, you decide. Appearance intervals run from every 30 minutes to every 4 hours, and Android's own scheduling floor keeps the layer battery-boring.

Why it suits the Samsung Galaxy Z Fold 4

Since Android 17 made floating bubbles the platform's own multitasking language, a memory bubble on a 2022 Samsung feels native rather than novel — the interaction is familiar; only the contents change. Instead of another app icon, the bubble holds a photo from years ago, a short video, or a message thread you saved because it mattered. The Mystery Photo option keeps one genuine surprise in the rotation.

Setup on the Samsung Galaxy Z Fold 4 in five minutes

Install from Google Play ($2.99, once — no subscription, no ads, no account). Add your first memories from the gallery, allow the overlay permission when One UI foldable asks, pick a frequency, enable Floating Bubbles, and fire the Test Bubble to confirm. From that moment the Samsung Galaxy Z Fold 4 does something no stock gallery does: it hands your past back to you during ordinary use, entirely on-device.
