The in-display optical fingerprint sensor almost never works on custom ROMs for Exynos 9611 devices. Some builds claim to have fixed it, but in practice – unreliable or completely broken.
| Metric | OneUI 4.1 (Stock) | Pixel Experience GSI (A13) | | :--- | :--- | :--- | | Boot Time | 45 sec | 22 sec | | RAM Usage (Idle) | 2.8 GB / 4 GB | 1.6 GB / 4 GB | | Battery SOT (4000mAh) | 5.5 hours | 4.8 hours (worse due to missing power HAL) | | Gaming (BGMI/CodM) | 30 fps (stutter) | 28 fps (stable, lower thermal throttle) |
Conclusion: Performance is smoother, but battery life decreases by ~15% due to inefficient Exynos PowerHAL on AOSP.
Custom ROMs can noticeably improve the Galaxy A50s lifespan and user experience—faster UI, longer battery, and modern Android features—but expect compromises in camera fidelity and potential instability unless you choose well‑maintained, device‑specific builds. If you value longevity and customization and are comfortable with flashing, installing a reputable LineageOS or Pixel Experience build is a worthwhile upgrade; if you rely heavily on camera/fingerprint or Samsung services, stay on stock or proceed cautiously.
(Reminder: follow device‑specific guides and community threads for the exact A50s model variant before flashing.)
