VladTudor Open Beta is closed because Stable has been released. That is why it says you already have the latest firmware.
It will open again for the next Open Beta, probably Android 15. 
📱 Phone (2) - Nothing OS 2.5 Changelog
When will they add or enable the option to use a USB-C external microphone with the native camera on the Nothing for recording videos with better audio quality? As a content creator, this is the only missing feature, along with stabilization for the wide-angle camera. Someone, please take this into consideration. It works with the voice recorder, TikTok, or a GCam but not with the camera app.
Does anyone know how to activate it? I need it."
still no support for hig framerate gaming 
SrsThewrongguy me too ,
AmirHussaini OK, so this update is first rolling to only beta tester and then may be if any bug comes up, the dev team will fix it and then roll back to the stable user.
BhupinderSingh_ECdZcBAIs3 I am afraid is not like that bro, because the update appears on the System update, not from the Beta upgrade tool app. It means it’s a Stable release.
If it appears on the Beta upgrade tools app, then makes sense as you said.
They also mention this.
Firmware (bot) Firmware rollouts are usually staggered, meaning not all users will receive the update simultaneously. This approach allows us to monitor for any issues and ensure a smooth and stable deployment.
The reason is to avoid more lucky people facing the same problem.
By right, some users starting to get the update. It is better late than never to get the update.
souravgk is it need to change auto update in developer option to get 2.5
Still no update………
TejasMaisuriya no, that is why I am concerned, if nothing sent a faulty cable via flip kart how do I get it changed or replaced. And I tried multiple times (14 to be exact). Had 80gb of data to be transferred. Even nearby share on this phone is inconsistent. Between my tab s9 and oneplus 8t there is a constant speed of 50+MBps while sharing. NOTHING barely touched 35+. That’s why I needed the data transfer from PC.
Default call redirecting app is not working broken after updating to os 2.5.1 and unable to place call from links on website or apps where u click on phone number link and it opens phone dialer for calling
I reset the phone by going to recover
And factory reset is but still the issue persist
Is any one else facing this issue
Pranjal_XjoE9068VS omg thats huge hope it ll fix
Pranjal_XjoE9068VS and pranjal if i may ask which android virson u using is it android 14?
NikitaHiDukov There’s an option of glyph music visualisation through which if any music other than the Nothing composed are played, it will try to sync the beats with the glyphs
Erling ahh, is that glyph hidden features? Need to add contact Alakazam and then Music Visualisation will unlocked.
I’m not using much that one because worry the battery drains much faster hahaha.
I just tried, don’t how to describe it because it follows the beat but sometimes like you said, out of sync. hahaha
The same thing happened to me, I found this solution, I went to settings-apps and looked for the Google phone app, click force stop and then uninstall from the play store, actually I think it goes back to the default version of Android, now it asks you Update the app and it’s solved for me for now.
sorry if the images are in Spanish, it is my native language
I haven’t received any update…
No Update in india after 4 days
JigarMistry they said this update for beta users non beta users will get update after 4 days
No update till now such a joke now I regret not buying a phone from BBK electronics or even better a Samsung or pixel. Already there is a bug of touch issue in 2.0.4 not gonna recommend this phone to anyone.
