Hello. I find it frustrating not having a basic time / calendar widget for OS4. I mean this is so basic.

I’m using this device for More then 3 months,but after the update the battery was draining more compared to new one ,and also when I take photos continuously the camera was struggling to take photo and by time it stopped and doesn’t click any photo ,but video option working properly. Whatever I do it doesn’t work , it works only when I restart the device, what should I do? 🙃🤷

Is there anyone facing the same issues?

After the NOS 4 update…

While capturing photos…they are good at 1x and 2x but while clicking photos on 4x the photos become abnormal and of different colour having a lot of contrast and saturation

ISSUE: When VPN is active (Cloudflare WARP 1.1.1.1), downloads in the Browser (Brave) get paused in the background.

DETAILS:

If download in browser is started first (before vpn is turned on), Brave shows up in the Active Apps list. While download is ongoing, if I turn on vpn, then Brave stays in Active Apps, Active Apps now shows ‘2’ (both 1.1.1.1 and Brave) and everything works correctly…
But if VPN was active beforehand (and is showing in Active Apps) and I newly open Brave and start a new download, Brave does not get added to Active Apps. Active Apps keeps showing ‘1’ (only 1.1.1.1). In this case, background downloads get killed after a minute or two.

PS: Note that all battery saving features are turned off (Battery Saver, Adaptive Battery). Both apps (Brave and Cloudflare 1.1.1.1) are set to Unrestricted Background Usage.

Hello Nothing Team,

I am using Nothing Phone 3a. After the latest update (last updated: 1 November 2025), the Portrait mode background blur is not working.

When I take photos in Portrait mode, the subject is detected but the background does not blur at all, or the blur is very weak even in good lighting conditions. This issue was not present before the update.

I have already tried:

Restarting the phone

Clearing Camera app cache

Using Portrait mode in good lighting

The problem still persists. It seems to be a software issue introduced in the recent update.

Please fix this issue in the next camera/system update, as portrait mode is an important feature.

Thank you.

Device: Nothing Phone 3a

Camera App Version: 16.0.01.04.00

OS: Nothing OS (latest)
