Long Review: Galaxy A50s Custom ROMs – Breath of Fresh Air or Buggy Mess?

Device: Samsung Galaxy A50s (SM-A507F)
Tested ROMs: Pixel Experience Plus (Android 13), LineageOS 20, Project Elixir 3.8
Usage Period: 3 months

B. Pixel Experience (PE)

Versions Available: Android 12, 13.
Overview: As the name suggests, this ROM aims to replicate the Google Pixel software experience perfectly on the A50s. It includes Pixel-exclusive features like the Pixel Launcher, GVisual UI, and exclusive wallpapers.
Pros: Aesthetic appeal, integrated Google features, generally very smooth performance.
Cons: Can be slightly heavier on RAM than LineageOS due to Google services overhead.

4. Technical Considerations for Exynos 9611

The Galaxy A50s utilizes the Exynos 9611 chipset. This presents specific challenges for Custom ROM developers:

Source Code Availability: While Samsung releases kernel sources, the proprietary drivers for the GPU (Mali-G72 MP3) and ISP (Image Signal Processor) are often closed-source. This requires developers to reverse-engineer or "shim" drivers, leading to potential instability in early ROM builds.
SELinux Policies: Many Custom ROMs for the A50s may ship with SELinux set to "Permissive" rather than "Enforcing" to ensure functionality. This is a slight security reduction, though modern builds generally aim for Enforcing status.
VoLTE/WiFi Calling: Depending on the region (India vs. Europe), VoLTE support on Custom ROMs can be hit-or-miss. Users often need to flash specific carrier blobs or modems to restore this functionality.

Final Score: 7.5/10

The Galaxy A50s custom ROM scene is alive and impressive for a mid-range Samsung from 2019. It revitalizes the phone, making it faster and more battery-efficient than the day you bought it. But the VoLTE and camera compromises are real deal-breakers for many. If you can live with them, the A50s becomes a fantastic secondary device or a solid daily driver for privacy/performance nerds.

Would I do it again? Yes – on a spare A50s. No – on my main phone.
