Android evolves through successive waves of system updates, often silently, which profoundly change the management of privacy, battery, and multitasking. Understanding these mechanisms allows users to take advantage of features already present on most smartphones without installing third-party applications. Here are the most concrete ways to benefit from the latest developments in Android.
Private Space on Android: protecting sensitive applications
Since Android 15, a feature called Private Space allows users to create an isolated area on their phone. Applications placed in this space are invisible from the main launcher, and their notifications are completely hidden.
Access to this area requires a separate PIN code or biometric authentication. The principle is similar to a second user profile, but integrated directly into the system, without having to juggle between two sessions. The affected applications do not appear in the recent apps list or in search suggestions.
This approach addresses a specific need: to separate banking, medical, or professional data from the rest of the device. Several resources detail these developments and other Android novelties, particularly on https://androidinside.fr/, which regularly covers system updates.
To activate Private Space, go to Settings, then Security and Privacy. The feature appears under the section dedicated to private spaces. Once configured, isolated applications do not consume any resources in the background as long as the space remains locked.
Anti-theft lock and protection of critical settings on Android
Android 15 has also strengthened the physical protection of the phone. The Theft Detection Lock feature uses motion sensors to detect a sudden removal of the device. If the behavior corresponds to theft, the screen automatically locks.
Beyond this reactive locking, sensitive settings (SIM card change, factory reset, location disabling) now require additional authentication. A thief accessing an unlocked phone can no longer neutralize the protections in a matter of seconds.
These two layers of security work without third-party applications and without a network connection for the initial detection. They complement the remote lock already offered by Google Find My Device.
Check that these protections are active
- Open Settings, then Google, then Device Security. The Theft Detection Lock can be activated with a toggle there.
- Ensure that the factory reset protection is linked to a Google account. Without this link, the feature loses its utility.
- Test remote location from a browser via the Find My Device dashboard to confirm that the device correctly reports its position.
Background process management: what changes for battery life
Recent versions of Android modify how the system manages background processes. The principle: applications that have not been opened for a certain time see their activities restricted more aggressively.
In practical terms, this means fewer unexpected wake-ups of the processor, fewer unnecessary synchronizations, and reduced energy consumption at rest. The effect is particularly noticeable on devices with modest batteries.
Adjusting behavior on a per-application basis
Android allows users to choose, for each application, between three levels of restriction: unrestricted, optimized, and restricted. The setting can be found in Settings, then Apps, then selecting the app, then Battery.
The “optimized” mode is suitable for the majority of uses. The “restricted” mode cuts almost all background activity, which may delay the receipt of notifications. Reserving the unrestricted mode for messaging and navigation applications helps maintain battery life without missing messages.
Bubbles and Android multitasking: beyond conversations
The Bubbles feature, initially limited to messaging applications, now extends to other types of applications. The principle remains the same: a floating window allows interaction with an app without leaving the one currently in use.
On foldable devices, a new bubble bar interface allows opening more than two applications simultaneously and navigating between them. On a standard smartphone, the advantage is to keep a converter, calculator, or shopping list accessible in overlay.
To activate bubbles on a compatible application, go to its notification settings and check the corresponding option. Not all applications support this feature yet, but third-party developers can integrate it via Android’s BubbleMetadata API.
Gemini and the transition from Google Assistant
Google is gradually replacing Assistant with Gemini on recent Android devices. The main difference lies in the engine: Gemini is based on a generative artificial intelligence model, capable of producing longer contextual responses and handling complex queries.
Older phones running Android 9 or an earlier version with less than 2 GB of RAM retain a lightweight version of Assistant. This creates a clear difference in experience depending on the device used: basic voice commands on one side, advanced conversational interactions on the other.
To check which version is active, press and hold the home button. If the Gemini interface appears, the transition has already taken place. Otherwise, activation can be done from the Google settings under the Gemini section.
The switch to Gemini also modifies automated routines. Some custom commands created for Assistant require reconfiguration, as the syntax and triggers differ between the two systems. It is better to recreate routines after migration rather than relying on automatic compatibility.
