I upgraded my CMF Phone 1 to Android 16, but the Linux Terminal feature is not working. How can this issue be resolved?

They locked down the NOS 4.0 update in many ways. Reckon the terminal is a part of that.

Hey guys cmf phone 2 pro user here how’s it going with the new NOS 4 with you guys is it overall degrading your phone’s performance and experience? or is it optimized

mentalkan

Womey I think, Linux terminal is needing another a cpu’s unit.

Hey guys, I’m from Bangladesh and recently I tried to change my region on my CMF Phone 1 and I have noticed that there is no Bangladesh region in my device. I also didn’t find Bangladesh region on my Clock “HOME TOME ZONE”.

For you info I bought this phone when I was studying in India and I returned from there after completion.

My build number is Tetris-B4.0-251216-1717-IND

I am attaching some screenshots if anyone doesn’t understand with what I am facing problems

ayk123 Hey I wanna know how your status bar (battery, network etc..) looking like different? Like it’s really looking good can you tell me how you did it?…🤔

allesia_fontana

I saw someone posting this with a 900000+ score… is there a difference in antutu versions?

JP

allesia_fontana yes .. v10 is older version…which op has used to get 674k score…v11 is newer version…which uses newer algorithms so scores are higer… its around 20% higher…

AswinSajeev

allesia_fontana Yeah, My cmf phone 1 scored over 740k in NOS 3.2 in Antutu version 11.0.5! I’m not sure how it’ll perform in OS 4.0 as I haven’t installed the update yet bcz I’m still waiting around to see how stable it is and decided to go through some reviews as well😅..
