Are there any updates after the Beta for Nothing phone 2

DebankarChaku

I update Nothing 4.0 Open Beta some days ago. I’ve got some major problems.
(1) The camera is in a completely bad condition.
(2) Cannot take more than six photos at once in high resolution at 50 MP. Then it takes a while for the images to save in the gallery.
(3) After taking a picture in high resolution, it is saved at 1.3 megapixels. Is it funny ??
(4) The video is disgusting enough . I’m really stuck with the update
(5) A new problem has arisen recently. The settings suggestion is not working properly. I can’t search anything with the settings for this .
I hope the problems will be solved soon & We will get the stable version soon

Anonymous952

ich werde mir nie mehr wieder ein Handy von Nothing kaufen das weis ich jetzt schon,

Punkt 1 in online shop keine Sachen mehr zu kaufen in Österreich

Punkt 2 immer wieder das selbe problem mit euren handy zwecks beta sobald man es zurücksetzt

und keiner will helfen daher verkaufe ich das handy

Anonymous963

Anonymous952 I’m hoping One Plus add Nothing 3a to their trade-in tbh… can’t wait to get rid of this thing now

Anonymous952

oki nach langen hin und her habe ich es endlich mal geschafft das rollback auf das handy zu bekommen :-)

Also nie mehr wieder beta updates

How did you manage that? My phone keeps trying to update back to Nothing OS 4.0 after I performed a rollback.

GrantBristow

Performance has been shocking for me on my phone 3 so laggy

So you're telling me I joined a beta program with my Nothing Phone (2), hoping to help the community, and now I'm stuck with a version that drains battery and isn't very stable—only for someone to decide I'm no longer part of it? And if I want a stable phone again, I have to wipe everything?

How to solve this
