Samsung S9+ Exynos Custom ROM Review: A Breath of Fresh Air
As a long-time user of Samsung's flagship devices, I was excited to dive into the world of custom ROMs on my S9+ Exynos variant. After installing a custom ROM, I was blown away by the newfound flexibility, performance, and features that I never thought possible on my device. In this review, I'll share my experience with the custom ROM on my Samsung S9+ Exynos.
Installation Process
The installation process was relatively smooth, but I had to do some research to find a reliable source for the ROM and the necessary tools. I opted for the popular LineageOS ROM, which is known for its stability and feature-rich experience. I followed a well-documented guide on XDA Developers, and after a few reboots, I was up and running with my custom ROM.
Performance
The first thing I noticed was the significant improvement in performance. The custom ROM brought a much-needed boost to my device, with animations feeling smoother and more responsive. The Exynos chip, which was previously criticized for its performance, now felt on par with its Snapdragon counterpart. I was able to play demanding games like PUBG and Fortnite at high graphics settings without any noticeable lag.
Battery Life
Battery life has been a pleasant surprise. With the custom ROM, I've seen a noticeable improvement in battery endurance. I attribute this to the removal of bloatware and the optimization of system services. On a single charge, I can easily get through a day and a half of moderate to heavy use.
Features
One of the best aspects of the custom ROM is the ability to customize almost every aspect of the device. I've added features like:
Camera Performance
The camera performance on the custom ROM is on par with the stock firmware. I've noticed no significant differences in image quality, and features like Live Focus and Super Steady video stabilization work flawlessly.
Bugs and Stability
While I've experienced some minor bugs, such as occasional freezes and app crashes, they've been relatively rare. The community support for LineageOS is vast, and I've been able to quickly find solutions to any issues I've encountered.
Verdict
The custom ROM on my Samsung S9+ Exynos has breathed new life into my device. I've gained a level of customization and control that I never thought possible on a Samsung device. While there are some minor bugs, the overall experience has been extremely positive.
Recommendation
If you're a Samsung S9+ Exynos user looking to breathe new life into your device, I highly recommend exploring custom ROMs like LineageOS. Be prepared to invest some time in research and installation, but the payoff is well worth it.

If you are looking to revitalize your S9 Plus, this guide covers the best custom ROM options and the current state of development as of 2026. The Current State of S9 Plus Custom ROMs (2025–2026)
As of early 2026, the S9 Plus (models G965F/FD) has entered a "legacy" phase of development. Most modern ROMs for this device are ports—software taken from newer Samsung devices (like the S24 or S21 FE) and modified to run on the older Exynos 9810 hardware. 1. Noble ROM: The One UI Standard
For many, Noble ROM is the definitive choice for the S9 Plus. It aims to provide the latest official Samsung experience on older hardware.
Latest Versions: Includes ports of One UI 6.1.1 (Android 14) and One UI 7.0 (Android 15).
Pros: Access to modern features like Galaxy AI (Generative Edit), updated Samsung Dex (no external display needed), and the latest Always-On Display (AOD) styles.
Cons: Higher battery drain than lighter ROMs; the rear camera on the S9 Plus may require specific older patches for full stability in some One UI 7 builds. 2. LineageOS & AOSP ROMs: For Speed & Longevity
If you prefer a clean, "Google Pixel-like" experience over Samsung's heavy software, AOSP-based ROMs are your best bet.
The story of the Samsung Galaxy S9 Plus (Exynos variant) in the custom ROM world is one of defiance against planned obsolescence. While Samsung officially ended support for the device in April 2022 after reaching Android 10, a dedicated community of developers has kept the hardware relevant well into 2026.

versions (like One UI 7) that Samsung never officially released for the S9+.

The Samsung Galaxy S9 Plus (Exynos) remains a popular choice for custom ROM enthusiasts because its bootloader is more easily unlockable compared to the North American Snapdragon variants. As of April 2026, the development community continues to provide updates that bring newer Android versions and features to this legacy hardware. Top Custom ROMs for S9+ Exynos (star2lte)
Noble ROM: This is arguably the most popular choice for users who want to keep the Samsung "experience." It ports newer versions of One UI (currently up to One UI 7 on Android 15) to the S9+. Developers like AlexisXDA (XDA) provide builds that include modern features like Object Eraser and Remaster Picture that the original firmware lacks.
LineageOS: The gold standard for a "clean" Android experience. Official and unofficial builds of LineageOS 21 (Android 14) or higher are available, offering significant performance improvements by removing Samsung's heavy software skin. You can find these on the LineageOS Downloads page or community threads.
Pixel Experience: Ideal for those who want their Samsung to look and feel like a Google Pixel. It includes Google apps (GApps) pre-installed and brings Pixel-exclusive features like the Google Photos unlimited backup (via spoofing) and the Pixel launcher.
Evolution X: A "best of both worlds" ROM that combines the Pixel look with deep customization options. It is frequently updated with the latest security patches. Key Prerequisites
Before flashing any custom ROM, you must ensure your device meets these technical requirements:
Exynos Chipset: Verify your model is SM-G965F, SM-G965F/DS, or SM-G965N. Snapdragon models (SM-G965U/U1/W) generally cannot use these ROMs.
Unlocked Bootloader: You must enable "OEM Unlocking" in Developer Options and follow the device-specific unlock procedure.
Custom Recovery (TWRP): You need TWRP (Team Win Recovery Project) installed to flash the ROM files.
Data Backup: Flashing a new ROM will wipe all internal storage. Common Issues & Considerations
VoLTE/VoWiFi: In most non-Samsung-based ROMs (like LineageOS), VoLTE and Wi-Fi Calling will not work due to proprietary Samsung drivers that cannot be ported to AOSP. If you need these, stick with Noble ROM.
Camera Quality: Samsung’s stock camera app is highly optimized for the S9+ hardware. While AOSP ROMs use GCam ports to improve quality, the stock Samsung camera experience is usually best on One UI-based custom ROMs.
Knox Trip: Flashing a custom recovery will permanently "trip" the Knox security fuse, disabling Samsung Pay and Samsung Pass forever on that device.
Here’s a grammatically proper version of your phrase, depending on how you intend to use it:
