Because development for this specific chipset (SM-A015F with Spreadtrum/Unisoc SC9832E) is niche, Generic System Images (GSIs) are your primary source. Here are the top stable performers:

If you manage to unlock the bootloader and successfully flash a custom ROM, the question remains: Is the A01 actually better?
Performance Gains: The most noticeable improvement is the removal of Samsung Bloatware. One UI is feature-rich but heavy. Stripping that away for a lightweight custom ROM can actually make the Snapdragon 439 feel snappier. App opening times improve slightly, and the phone feels less "bogged down" by background processes. custom rom samsung a01
Battery Life: Results are mixed. Some lightweight ROMs improve battery life by killing unnecessary background tasks. However, poorly optimized ROMs can drain the battery faster, especially if they do not handle the processor's "deep sleep" states correctly.
Functionality Quirks: This is the biggest downside. On budget Samsung devices, custom ROMs often struggle with proprietary Samsung drivers. Common issues include:
Q: Will banking apps work? A: Most banking apps will work on custom ROMs, but some may detect root or unlocked bootloaders. You may need to use Magisk (root solution) and enable "Zygisk" to hide the root status from banking apps. Because development for this specific chipset (SM-A015F with
Q: Can I go back to Stock Samsung? A: Yes. You can download the official Samsung firmware for your region and flash it using Odin. This will re-lock the bootloader (in some cases) and restore the phone to its original state, though the Knox warranty void flag is permanent.

Unlike flagship devices like the Galaxy S series, the A01 has a smaller, but dedicated, developer community. The development scene has been split primarily between devices with unlockable bootloaders and carrier-locked variants (which significantly limits modding). If you manage to unlock the bootloader and
Here are the primary types of ROMs available for the A01:
The Samsung Galaxy A01, released in early 2020, was the definition of an entry-level device. It was designed to get the job done—calls, texts, and light social media—at the lowest possible price point. However, with Samsung’s official software support for this device winding down (or having ended), many users are left with aging software and sluggish performance.
For the tech-savvy owner, installing a custom ROM is the most effective way to extend the lifespan of this device. This write-up explores the current state of the custom ROM scene for the A01, analyzing the options available, the pros and cons of modding this specific hardware, and what users can expect from the experience.
Warning: Installing custom ROMs can brick your device, void warranty, and erase data. Proceed only if you accept those risks.
