Bliss ROM is a popular name in custom development that has managed to maintain a fine equilibrium between the overall feature set and the device stability. So on one hand, you will be welcoming a plethora of new and intriguing features onto your device, but at the same time, there wouldn’t be any dent in the performance domain. So a ROM baked in with interesting features and still not being the bloated OS, well, we couldn’t have asked for more.


As far as the Pixel 4A is concerned, I got to test it only for a couple of minutes, but I did manage to grab hold of some nifty functionalities. These includes:

  • Three-finger swipe for screenshot
  • Remove on-screen navigation bar pill
  • Two-button navigation
  • Double-tap to sleep
  • Screen Lock Animations
  • Ambient Edge Lightning
  • Advanced Power Menu
  • A plethora of Battery Styles, Icon Shapes, Signal, and WiFi Network styles.



While the developers haven’t listed out any bugs as such, I had faced a couple of issues. These included the device crashing when enabling Extreme Battery Saver Mode or when trying out WiFi Calling and the Advanced Reboot option missing from Power Menu, If you come across any such issues, then it is recommended to take a log and report it directly to the developers either at XDA or GitHub.
