Troubleshooting Android in 2026 is no longer just about clearing a cache or forcing a restart. The changes introduced by Android 14 and 15 regarding permission management, intent filtering, and storage restrictions profoundly alter how issues manifest and are resolved.
Intent Filtering and Screen Protections in Android 15: Diagnosing Real and False Bugs
Android 15 tightens intent filtering and strengthens protections against screen capture and sharing. In practice, mirroring, screen recording, or content-sharing apps that worked under Android 13 or 14 stop responding after the update. This is not a hardware failure.
The mechanism is simple: an intent declared too broadly by the developer is no longer resolved by the system. The flow fails silently or exhibits inconsistent behavior (black screen during casting, recording that cuts off, sharing that loops). We observe that the majority of these malfunctions disappear after reconfiguring the affected application, sometimes simply by uninstalling and then reinstalling it to force the re-declaration of intents compatible with Android 15.
Specialized technicians like those from sosandroid.fr regularly intervene in these types of cases, where the user suspects a hardware defect while the problem is purely software-related.
Before looking further, test sharing or capturing with a native Google app (Google Meet for screen sharing, for example). If the native app works, the issue lies with the third-party application and its compatibility with the new intent rules.
Auto-Revoke Permissions and Restricted Storage on Android 14-15
Since Android 14, the system automatically revokes permissions from unused applications after a period of inactivity. Android 15 extends this behavior to sensitive permissions, including access to files and background location.
The typical symptom: an application that you haven’t opened for several weeks loses access to storage or the camera. Upon reopening, it displays an error or a blank screen. This is not a bug; it is the expected behavior of the system.
Check and Restore Revoked Permissions
- Open Settings, then Apps, select the affected application, and go to the Permissions section to check which permissions have been removed
- Disable the option “Suspend app activity if not used” for critical applications (file manager, backup app, VPN)
- Under Android 15, also check “Sensitive permissions” in the security settings, as some permissions no longer restore from the classic app screen
A common pitfall concerns automatic backup or cloud synchronization applications. They run in the background without user interaction. The system considers them inactive and revokes their storage permissions, which silently interrupts backups.
Scoped Storage Restrictions
Android 14 and 15 impose a stricter scoped storage model. Applications can only access their own directories unless explicitly permitted via the system file picker. A third-party file manager that worked under Android 12 may find itself unable to read certain folders after the update.
We recommend checking in Settings > Apps > Special Access > Access to all files that legitimate applications have this permission. Without this verification, some file transfers fail without a clear error message.
Android Troubleshooting Related to Overheating and Battery: Beyond the Obvious
Battery diagnostics on Android are not limited to identifying the most power-hungry application in the settings. Two technical causes deserve particular attention in 2026.
The first concerns undeclared background activities. Android 15 further restricts background activities, but some applications bypass these restrictions through abusive foreground services. The symptom is abnormal consumption without any application appearing as responsible in the system battery monitor.
To identify these services, access the Developer Options (by tapping the build number several times in the settings), then check the “Running services” section. A constantly active foreground service without a visible reason (persistent notification from an app you are not using) is a likely candidate.
The second cause, more subtle, is related to partial firmware updates. After a system update, the cache of the partition may contain incompatible data that causes abnormal processor wake-ups (wakelocks). A reboot in recovery followed by a “Wipe cache partition” (which does not delete user data) resolves this type of battery drain in most cases.
Android Reset and Right to Repair: What Changes in 2026
In practice, Samsung and Google already offer built-in diagnostic modes (USSD codes or dedicated apps) that allow testing the touchscreen, sensors, mobile network, and battery without going through an authorized center. On Pixel devices, the built-in “Diagnostics” app provides access to comprehensive hardware tests.
- On Samsung, dial *#0*# from the phone keypad to access the complete hardware diagnostic menu
- On Pixel, search for “Diagnostics” in the settings or use the built-in app
Before any factory reset, exhaust less destructive options. Safe mode allows isolating a problem caused by a third-party application. The wipe cache partition in recovery addresses post-update corruptions. A complete reset remains the last resort, not the first reflex.
The repair bonus in France, extended to smartphones, covers part of the cost for hardware repairs performed by certified repairers. Check eligibility before replacing a device that may simply require a battery or screen change.
