can significantly improve its usability by removing heavy bloatware and potentially upgrading it to newer Android versions like Android 13 or 14 via LineageOS.

is notoriously slow due to its Qualcomm Snapdragon 439 processor and limited 2GB of RAM. Custom ROMs aim to fix this:

Speed: Users report that LineageOS is "amazingly stable and fast" on low-end hardware, with virtually no UI stutter compared to the laggy stock One UI.

Storage: Stock software leaves only about 3.4GB of usable space. A clean AOSP-based ROM can free up several gigabytes by eliminating pre-installed carrier apps.

Battery Life: LineageOS has been noted to be roughly 50% more efficient than stock software on some devices, helping the A01's 3,000mAh battery last longer. Top Custom ROM Recommendations Key Highlight LineageOS Stability & Lifespan

High level of visual tweaks without sacrificing the reliability of the base software. Critical Risks & Limitations

VoLTE Issues: A major drawback on Samsung devices is that VoLTE (Voice over LTE) often fails to work on AOSP-based custom ROMs, which can break calling functionality on many modern carriers. Camera Quality:

You may lose advanced stock camera modes. Photos in custom ROMs often use basic processing, which can make the already mediocre camera perform worse in low light.

Security: Unlocking the bootloader and using non-hardened ROMs like LineageOS can reduce overall device security compared to stock Android.

Step 5: Flash TWRP Recovery

  1. Boot phone into Download Mode.
  2. Open Odin, click AP, and select the TWRP .tar file.
  3. Uncheck Auto Reboot in Odin settings.
  4. Click Start.
  5. When flash finishes, hold Volume Down + Power for 7 seconds, then immediately hold Volume Up + Power to boot into TWRP.

Target Audience: Samsung Galaxy A01 owners looking to speed up their device, remove bloatware, or get a newer Android version.

Install TWRP recovery (using Odin on Windows)

  1. Boot phone into Download Mode.
  2. Open Odin on PC; connect phone via USB — ID:COM should light up.
  3. In Odin, click AP and select TWRP .tar for your exact model.
  4. Ensure "Auto Reboot" is unchecked (to avoid booting stock recovery).
  5. Click Start. Wait for PASS.
  6. After flashing, manually boot to recovery immediately (usually Volume Up + Power) to prevent stock recovery overwrite.

Warning: This wipes all data on your phone.

In TWRP: backup and prepare

  1. In TWRP, create a full Nandroid backup (Boot, System, Data, EFS if available). Transfer the backup off-device afterward.
  2. Wipe: Use Advanced Wipe → select Dalvik/ART Cache, Cache, System, Data. Do NOT format /data unless required by ROM (some ROMs need data format to change encryption).
  3. If ROM requires data format (to remove encryption), use Wipe → Format Data and type "yes" — this erases internal storage.

Introduction

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.
