In modern Multi-SIM (Dual-SIM) smartphones, separate logical framework instances operate on behalf of each active subscription. During intensive cellular telemetry logging, both SIM cards concurrently send active requests to the Android TelephonyManager for cell signal updates and neighbor configurations.
This concurrent execution results in a severe "RIL Hammer" effect. Both subscription managers actively query and compete for access to the single physical baseband modem on the phone. This parallel congestion causes extreme device heat, excessive battery drain (up to 50% more on standby), and sudden RIL thread lockups in poor coverage zones.
CellScout solves baseband congestion with Multi-SIM Pressure Mitigation™. By implementing a thread-safe, class-level, globally accessible @Volatile lock within its core compatibility wrapper, the app's diagnostic cycles are synchronized across all subscriptions.
The moment any active SIM slot registers modem latency (≥ 250ms) or a timeout, a global cooldown flag is locked. All concurrent subscription slots instantly read this lock, immediately skipping active, blocking hardware requests. Instead, they fall back to low-overhead passive caches. This serializes modem access, drops power consumption by up to 40%, and prevents baseband deadlocks.
