Galaxy A01 Custom Rom 2021

The Verdict at a Glance

Installing a custom ROM on the Samsung Galaxy A01 is a mixed bag. While it is an excellent way to breathe new life into an aging, low-end device, the hardware limitations of the A01 mean you will likely face significant compromises regarding camera quality and performance stability compared to the stock experience.

What to expect (realistic benefits and limits)

Smoothness: Custom ROMs can remove bloat and improve responsiveness, but the A01’s low RAM and older CPU mean gains are moderate. Expect better perceived fluidity after debloating and light kernel tweaks.
Battery: Optimized kernels and aggressive Doze/config can extend standby and light-use battery life noticeably, but heavy use (gaming, camera) still drains quickly.
Features: Newer Android versions may be available via LineageOS-based or AOSP builds, bringing features (privacy dashboard, scoped storage improvements) not in stock A01 firmware.
Stability: Official device support varies. Many A01 builds are community-maintained with occasional bugs (camera, VoLTE, fingerprint if present). Choose mature builds for daily drivers.
App compatibility: Most apps run normally; banking/DRM apps may fail on rooted or uncertified builds unless you hide root/implement SafetyNet workarounds.
Storage: Space reclaimed from removed OEM apps helps; adoptable storage or custom partition tweaks possible but risky.
