ASB-V15.2 — Changelog

[V15.2] — 2026-03-02

🐛 Bug Fixes

  • tcp_slow_start_after_idle 1 → 0 — restores TCP cwnd after idle; faster 5G SA reconnect with BBR
  • Removed kgsl-3d0/min_pwrlevel=6 — unblocks Adreno 840 deep-idle states (levels 7–8)
  • Removed kgsl-3d0/bus_split=1 — was absent in V13.3/V13.4; idle_timer=80 ms preserved

⚡ Network

  • bpf_jit_harden=0 + bpf_jit_kallsyms=1 — restored from V13.4; zero-overhead BPF JIT for BBR/XDP
  • rp_filter=0 (all + default) — fixes CGNAT asymmetric-route drops on TIM Italy 5G SA
  • ip_nonlocal_bind=1 (IPv4 + IPv6) — completes rp_filter; enables Zapret / DPI bypass

🎮 CPU / Scheduler

  • foreground uclamp.min 8 → 15 — minimal UI floor, negligible battery cost
  • top-app uclamp.min 12 → 45 — V13.4 gaming floor; consistent 144 fps in CODM

🔇 Services (stop-list additions)

  • midasd — Qualcomm analytics daemon, persistent wakelock eliminated
  • batterysecret — OEM battery telemetry daemon, removes background I/O drain

🎵 Dolby Audio Pipeline (system.prop, +21 props)

Restored from V13.9 + new V14 spatial/game flags:
vendor.audio.dolby.ds2.enabled, ro.dolby.music_stream, ro.vendor.audio.dolby.surround.enable,
ro.vendor.audio.dolby.spatial.profile=music, ro.vendor.audio.dolby.dax.game.enable, and 16 others.

📡 Radio / IMS / PM (system.prop, +16 props)

  • Radio persist.radio.{power_save,add_power_save,data_no_toggle,NO_STAPA}=1
  • IMS logs disabled — 5 flags; saves background CPU on VoLTE standby
  • BT + Audio offload — persist.bluetooth.sbc_hd_higher_bitrate=1, audio.offload.min.duration.secs=31
  • Charge / Display / PM — persist.vendor.accelerate.charge=true, ro.vendor.display.vivid_calibration.enable=1, dev.pm.dyn_samplingrate=0

✅ Confirmed unchanged (not regressions)

Parameter Value Note
vm.dirty_expire_centisecs 6000 fewer writeback wakeups vs 3000
vm.dirty_writeback_centisecs 5000 same rationale
nf_conntrack_tcp_timeout_established 600 stock default since V13.3
