Nothing OS 3.0 | Open Beta 1 for Phone (2a) Plus
We all love the Nothing community. We are even told to keep improving it and sharing data. That’s what we do. But I don’t understand why NP1 users are so neglected. On top of that, when updates arrive, throughout the company’s history since OS 2.0 they have arrived with errors and disadvantages. Now, they tell us that in a few days we will have 3.0… that they are improving. Why? So that errors occur later? Please, we only ask that the time spent be of some use.We don’t want a beta in NP1 that doesn’t work for us. In 3 days, 3 releases. Now we’ll have to wait until December 25th to get the beta.
Rob 
updated now . I can’t launch nothing gallery from my camera 
pls fix the problem
MontyPython do you faced any data loss?
When we get for phone 1 waiting with patience???
HarshKhangarot Not so far. Everything seems to be great with the Beta, even the akk
MontyPython These seem like good data, let’s hope that this beta is made with a lot of love, care and tact for the company’s mobiles. Now all that remains is to finish this period with the launch of NP1, who knows if this roadmap will be followed or we will have to wait until Christmas week. It seems that he is behaving well anyway, anything informs…
Has anyone faced data loss?
I have my apps in a specific layout spread across 6 different pages on my nothing phone. When I upgrade to beta it will factory reset and will I have to arrange all the apps in that order again?
After installing the Beta update, my front camera became foggy. It was very clear before the update.
Rob is there any chance instagram incoming vibration not working fixed this update
previaxii_desu i noticed that skin tones are not that accurate. Hopefully this will be addressed when the first stable version comes out.
am i the only one who didn’t get the features for bringing the n dot fonts back and gallery isn’t defaulted yet i still can’t open it from my camera and a few more features that’s on phone 1 and cmf are not in 2a plus
High refresh rates don’t work
The settings of high and dynamic 120hz refresh rates don’t work in this beta. Install at your own risk.
TapLer_NoT_fOuNd It works for me. Switching to 60hz also makes a difference and is noticeable.
Mine doesn’t, high, dynamic and standard are all the same. Any tips on how to get it working again?
