Lost Odyssey Steprant Android 1.5

Download Steprant Android 1.5 APK · Android guide · Full verification

An independent Android edition maintained by Steprant, based on the official Lost Odyssey Recomp v1.1.0 by Frank / freefrank and the original community. Steprant 1.5 uses its own app version, icon and package.

Included in 1.5

• Qualcomm SGSR1: optional spatial reconstruction in the Vulkan SDR presentation path. Enable Settings → Graphics → SGSR1, choose the High scaling filter and an input resolution below output, such as 720p → 1080p, then save and restart. Native-size output, downscaling, HDR and temporal-upscaler output retain their normal paths. SGSR1 is not frame generation.
• TV / HDMI: independent 16:9 external output, 720p/1080p requests and controller forwarding. With phone blackout enabled, touching wakes the phone and blackout returns 10 seconds after the last touch, without covering the TV image. The phone panel remains powered.
• Extreme Tester: the Intensive profile records until manually stopped or an I/O/storage error, with no two-minute time limit. Configurable 250–2000 ms process sampling, bounded traces/ZIP export, process-memory samples and an estimated 1% low accepted-present rate. Thermal/battery data depends on Android; diagnostic recording can add overhead.
• EXP ×2 and SP ×2: independent saved switches in LB+RB → Cheats → Quick tools. EXP retains the game's per-battle cap; SP doubles victory skill points before learning. Gold and existing skill progress are unchanged.
• Audio fixes: queue-reserve recovery, AAudio reopen protection and XMA scheduling corrections are retained. 1.5 corrects an unsigned-wrap value in guest-wait diagnostic logs. Some crackling/audio disturbances remain; A/V synchronization requires device testing. The logging correction does not establish a new audio root-cause fix.
• Android performance work: renderer and CPU changes target redundant barriers, covered clears, descriptor/pipeline lookups and shadow bookkeeping. Lower CPU/GPU load, heat and battery consumption are optimization goals. No measured whole-game FPS uplift, temperature reduction or battery-life gain is claimed for 1.5.

APK and installation

LostOdyssey-Steprant-v1.5-20261104.apk — 47,694,826 bytes. Requires Android 8.0+, ARM64 and Vulkan.

Manifest: versionName 1.5 / versionCode 1050000. Package: io.github.freefrank.lostodyssey.steprant; launcher: Lost Odyssey Steprant, with the Steprant icon. It can coexist with the official app; saves and settings are separate. Future Steprant updates must retain the same signing key.

APK SHA-256:

Verification and remaining limits

The public download was checked again on 5 November 2026. The computed SHA-256 matches GitHub's asset digest; ZIP/ARM64 structure, APK v2 signature, manifest identity/version and 16 KB alignment pass. The signed release APK uses this fork's Android debug certificate, SHA-256 ecaadcdc715ff7e4aeaaf265ec11f1854d4039175dbc7e53fd4f86fd03af6f3f.

Prior build validation reports a complete ARM64 native build, 82 JVM tests, 15 host tests, 8 SGSR1 shader variants, Android TV probe checks and lint. These are build/synthetic checks, not newly repeated gameplay tests. No physical Xiaomi 14 gameplay run was performed for this publication check. Stable 60 FPS, HDMI/audio routing, A/V synchronization and power/thermal improvements need actual-device validation. The November 4 1080-internal-to-720-output traces do not demonstrate SGSR1 upscaling.

The native runtime embeds faf4842d87a6-dirty, indicating local build changes; a bit-for-bit reproduction from the release tag is not established. Hosted APK compilation remains blocked without authorized private build inputs; see the workflow findings.
