Cedrik Also the full rollout will be likely in Dec-Jan seeing the past timeline of 3.0. Might even take longer because of the increased features and stuff.

Arbaaz_rRhvxSXQI3

Did anyone updated ??

BrianWai

restared a few times already but still the same. and just fyi, there isnt an update either. 🙂

Sanjay_Yes

I think IND builds are not included in beta list. My nothing phone 2a plus has the same build version mentioned in the post but with suffix IND. It throws, “Your device model is not in the Beta Program”.

Would have been nice, if they included these models too.

JavedAlam_v0divUfKPW

Sanjay_Yes Try continuously let this error showing after 5-6 try you might get that update. I also have IND at the end in my Nothing Phone 2 but I got the beta update after that same error. I just kept retrying. You can give it a try, not sure if it works for everyone.

VaibhavRanjanJha

The green tint issue on the lock screen and on HDR content still persists
Dark mode is only applicable to the settings menu and slightly on the app drawer
No further changes on green tint on yt
No addition of custom wallapaper coloured icon pack
Addition of “modes” feature and now you can use camera presets
Overall smoothness is same
Screen tearing issue is still present in low brightness and normal scrolling

Let’s see how far it goes …..

AbinashBasa it’s just overwhelmed, try 2-3 times with breaks and it’ll work

A_mohamedWasiq

SohamKokil

Rob ⚡️

I am on the IND version of the nothing OS and am unable to access the beta update, is there going to be a different rollout for the different versions of OS?

nihalmjoshi

SohamKokil even I am on the India version but after 10 mins of trying I got the update on p2a and is now installing

Til21

aaritgupta891

Same as before 😄 I owned a pixel before and took in A16 Beta back in June and it has no changes at all. A16 M3 Expressive changed the status bar 😄

aaritgupta891

Til21 so the status bar would be updated later?

Bharathwaj

@VaibhavRanjanJha Did you notice the fingerprint recognition speed reduced when the screen is off and unlocking

aaritgupta891

Bharathwaj speed reduced? As in taking more time? Or the time reduced?

VaibhavRanjanJha

Bharathwaj yup and it’s also inconsistent

DhananjayKumar_ecdg5FoM8r

Bharathwaj yes

AkshayaKrishna

100hzpanic 🥲

Til21

aaritgupta891 I think so. Of course I am not part of the software team but with “Stock” android it was the same:-)
