Beta software, without rollback package.
Guys 
Nothing OS 3.0 | Open Beta 1 for CMF Phone 1
Dear Nothing team
As 2a plus users we feel one of the biggest mistake done is buying 2a plus phones as per trusting brand with genuine update panel. But see
- 2A
- Nothing phone 2
- CMF 1
4 is nothing phone 1 and 5 2A plus?
It’s totally unfair, going forward give beta to all or take 8 months too come up with a stable version. If this panel continues you may see lack of new customers.
Another beta release! 
Patiently waiting for Phone (1) and (2a) Plus. But it is still December, so I know that these builds are still being worked on.
Patience is a virtue guys. Let’s celebrate the team’s work with getting another device to a Beta build. 
The other devices will come, it is only a third through the month. Plenty of days before December ends! 
Honey_A2UDpMBgfJ yeah the half priced phone getting faster update
As per your statement better we can give this phone to older people in home. They will be super patience and no worry about the software updates and month like December 2024 or July 2025. Just use phones for calls
Finally nothing os 3.0 is here in cmf phone 1 Nice work software team.

Till now good experience with Nothing OS 3.0 in CMF Phone 1 (Good keep it up)
Sad for 2A Plus and Phone 1 User, maybe they can get update within 3-5 days
Beta released without rollback package. 
I wish they would release the update also that fixes issues currently in 2.6.
Nothing phone 2a plus we still waiting for the update…
Rob 
when we expect stable nothing 3.0 release in cmf phone 1.
Rob Good work team appreciated for your work. I want to ask is there is any loss of data after upgrading this nothing os 3.0 in cmf phone 1.
Phone 1 users crying in the corner 
Tetris-U2.6-241125-2107 Upgrade Package OTA Error.
DOWNLOAD STATE INITIALIZATION ERROR 20
Just a… disappoint movement by Nothing… becz.. every one expecting the Phone 1 update and 2a plus… becz.. there are more users than the CMF phone 1…
Nothing Do something quickly for Phone 1 and 2a plus
At least the wait is over will be free from the question “When will it arrive”
papaiaditya2002 yes bro they are babysitting cmf and 2a and phone 1 users al always waiting for years
SamarthNP1 waiting “for years” is a bit of an exaggeration don’t you think?
Maybe it is better to not have this beta on other phones as well.
On my cmf phone I have successfully upgraded from Tetris-U2.6-241021-2030 to this open beta.
And now the quick settings is not working (as shown in picture) and there is no way to downgrade
So maybe it is better to wait out the stable releases instead of stressing when the “beta”(unstable version) comes out to other phones.
Duxez on the start of this year phone 1 was getting late updates so only possible this was to wait
