✅ What’s new in v1.2.0
Hardware Revision Support (Important)
This release adds support across the MANGMI Air X hardware revisions, including devices with serials beginning with MQ65 and MQ66. If you have had issues on certain newer batches, this update is designed to address that.
Stability Improvements
Bugfix for Quick Settings closing randomly
Additional stability work to improve the overall SystemUI experience
GammaEQ Upgrade
GammaEQ UI application is now included
The GammaEQ engine has been in place, but v1.2.0 brings a proper UI so you can manage audio enhancement without relying purely on properties.
⭐ Core highlights (same foundations, better polish)
Core System and Base
Android 14 / LineageOS 21 base
Faster responsiveness and reduced background overhead
Updated security and graphics pipelines
Advanced Visual Features
Global shader pipeline including CRT-Simple and LCD3x
Long-press the Shader tile for configuration
DPI scaling and rotation handled automatically
GammaRGB Joystick LEDs
Multiple effect modes, improved control options, and brightness scaling
Long-press the RGB tile for advanced controls
Navigation and UI
Immersive Mode enabled by default for a console-like feel
Swipe edges to reveal taskbar and status bar
Ongoing UI responsiveness improvements
🔥 Recommendation (Full vs Lite)
For the best gaming performance and battery life, I strongly recommend GammaOS Lite. It removes Google services and typically delivers smoother performance and better efficiency.

Thank you for supporting GammaOS development and making continued Android 14 progress possible. If you run into anything odd (especially around hardware revision behavior), please report it via GitHub Issues or Discord so I can keep tightening things up.

antonio capillo

Jose Lebron
Installation was very smooth! I don’t seem to have the rgb tile or the shader tile though

Like LinkClick comment, everything is working with my GammaOS except the bluetooth audio and aux audio. Are there settings we need to tweak?
LinkClick
Just switched over and most everything is flawless. The only thing I have noticed is the Bluetooth audio and aux audio do not work. Is there something different I need to do?

I also noticed the vibration also seems bugged. I don't know if it's a known issue but on my MQ66 version the vibration stops working after some time. I didn't find any consistency in it
Gamma
I need to review the auto profile, for now max works best. The 4-5 times is normal in GammaOS. Both will be fixed in the next update.
Gamma
Simple update
Gamma
Hi, did you try recalibrating the sticks again?
Gábor Boros
How do the fan profiles work? Setting to auto not seems to do anything. Setting to max acting weird. The fan spins up and stops about 4-5 times before starting to spin normally. Is it normal or a bug? Seems kinda bugged to me, the stock OS never did this.
Seth
Do I have to fresh install every time or can I do a simple update from the November build?

Hey question, I got my air x 2 days ago and I flashed the gammaos and it was working great. But today my device has been scrolling left without me pressing anything and I can't get it to stop or play anything for that matter. Have you seen this issue or do you know how to fix it? This is across all my emulators not just one.

actually I've figure this out myself. #!/bin/bash if [ "${4}" = "Android Apps" ]; then /system/bin/sh -c "echo 1 > /data/GammaPad/ABXY_LAYOUT" fi
Joshvin Matthew Domingo
Is there a way for me to execute the "swap abxy" via the ES-DE event scripts? Background: I want certain android games to automatically enable the swap ABXY when the game is started via the ESDE
