Received the update.
📱 Phone (2) - Nothing OS 2.5.2 Changelog
Firmware (bot) “You can now directly set your network via Quick Settings without unlocking the device.” is this a setting or just a changed behavior? i like to have the added security of having to unlock the phone in order to turn off mobile data.
waiting for the update, hoping it will now support high framerate gaming 
Will check and update on this
Great work Nothing team!!!
Added support for switching ring modes in Quick Settings. can’t find this????
mayankdhaka If you are running 2.5.2, it shall be named under what your current Sound Profile is, ie Vibrate, or Mute etc.
Give it another check if you are running the update.

Weird bug in nothing wallpapers/ OS 2.5.2 -
Selecting default wallpapers from the customisation menu doesn’t work. You need to go to more wallpapers and then select the desired default wallpaper.
I am wondering, if the developers are checking the wishlist discussion 
Also can someone check, if this update brings the January security patch?
Rob,
I suggest you to keep an eye on XDA forum, specifically on the development part. Currently very good kernel is being developed and have a lot of improvement over the current one 
EmilKostov_7TOgRQt3EJ Yes, it’s now updated to Jan 1 security patch with NOS 2.5.2
ashutoshkumar_sg2 I think you should restart your phone once, it should fix it(probably)
Ealesy101 i am on 2.5.2 but, where do i find this setting its not available in quick settings. can send some screenshots?
- (Edited)
mayankdhaka It is a part of the Quick Settings in the Widgets section. As opposed to the quick settings drop down/notification shade.

Ealesy101 yes i know. but there is not option for sound profile.
Firmware (bot) Added support for switching ring modes in Quick Settings.
Even I am unable to find it in Quick Settings after updating NOS 2.5.2
mayankdhaka Can you please share a screenshot? I am not able to see it under Quick Settings under the notification shade nor under the Widgets section in Quick Settings.
Rob 
thanks.
Rob Wow. Hope this feature is enabled soon.
Very basic features are missing - Can’t see song playing on AOD, Icon Resizing options as even lowest display size has the icons pretty big etc
