Always-on display photos —
beyond the lock screen.

Always-on display is one of the genuinely useful features on modern Android phones. Samsung, Google Pixel, and others let you show a clock, notifications, or even photos on a low-power screen when the phone is idle. Glance at your phone without picking it up, see the time, see a photo.

It's well-implemented for what it does. But always-on display has a fundamental limitation: it only works when you're not using your phone.

The AOD limitation

The moment you unlock your phone and open an app, the always-on display turns off and the normal screen takes over. Your apps, your content, your attention — they all move to whatever you're doing. The photo you set for AOD is no longer visible.

This means AOD is great for moments of passive phone checking — quick glances at the time, seeing if you have notifications — but does nothing for the hours you spend actively using your phone. Most actual phone time is active use. Most actual phone time is when AOD is invisible.

What active-use photo display looks like

For photos to be present during active phone use — when you're in apps, browsing, texting, working — you need something that operates at the overlay level rather than the lock screen level.

Bubbles In Time is designed for this specifically. Using Android's display-over-other-apps permission, BIT keeps a floating photo bubble present over everything you do with your phone. It's not a lock screen feature. It's active during use, invisible when the phone is locked.

In that sense, BIT and AOD are complementary rather than competing. AOD handles idle phone moments. BIT handles active phone moments. Together they keep meaningful photos present across your entire relationship with your phone.

Setting up both

For AOD photos: Settings → Lock screen → Always On Display → add your chosen photo. The exact path varies by manufacturer.

For active-use ambient photos: get Bubbles In Time, add your photos, grant the overlay permission, set your schedule. Done.

Samsung-specific AOD + BIT

Samsung Galaxy phones have the most fully-featured AOD implementation, including photo support. They also run One UI, which has aggressive battery management that can affect BIT's background service. If you're using both AOD and BIT on a Samsung, set BIT to "Unrestricted" battery mode in Settings → Apps → Bubbles In Time → Battery to ensure consistent bubble delivery.

The bigger picture

Both AOD and BIT are trying to solve the same underlying thing: making photos present without requiring intentional gallery visits. AOD solves it for idle moments. BIT solves it for active moments. The philosophy behind BIT is that photos shouldn't wait to be found — they should find you, gently, throughout your day.
