The Galaxy A04 runs on a Unisoc SC9863A (not Exynos or Snapdragon).
That’s the first major problem:
Bottom line: Custom ROM development for A04 is nearly dead compared to Snapdragon Samsung phones.
Who is this for? If you are technically savvy, tired of the lag on your A04, and willing to tinker with settings to get VoLTE working, these new custom ROMs are a must-install. They transform the phone from a laggy budget device into a smooth, functional daily driver.
Who should avoid this?
If you rely on Samsung Pay, need guaranteed stability for banking apps, or don't know what ADB is, stay on stock. The A04 is a budget phone, and turning it into a beta-testing device might leave you without a working phone when you need it most.
Overall Score: 8/10 (For performance gain), 6/10 (For stability/ease of use).
Summary: The "new" wave of ROMs proves that the hardware in the Samsung A04 is capable of much more than Samsung's software allows. It just requires a brave user to unlock that potential.

Before flashing any custom software, several critical steps must be performed to avoid "bricking" the device: How to Install a Custom ROM on Any Android Phone (Example The Galaxy A04 runs on a Unisoc SC9863A
Here’s a deep, realistic review of custom ROMs for the Samsung Galaxy A04 (SM-A045F/DS) — based on current developer activity (as of 2026), community feedback, and practical limitations.
The Samsung Galaxy A04 is an entry-level Android handset that targets budget-minded users who need dependable battery life and basic smartphone features. While stock firmware from Samsung focuses on stability and long-term support for security updates, it also includes manufacturer customizations, preinstalled apps, and UI choices that may not suit every user. Custom ROMs — aftermarket firmware built by independent developers — offer an alternative: they can refresh an aging device, remove unwanted software, improve performance or battery life, and enable features the stock OS doesn’t provide. Installing a custom ROM on the A04 requires technical steps (unlocking the bootloader, installing a custom recovery, and flashing the ROM) and carries risks: voided warranty, potential instability, and the small chance of bricking the device. For many users the benefits are compelling; for others, the stock experience remains the safer choice.
