JP yeh. Will wait and see for 1 ,2 days, how it go

JefRoftin

JP the battery percentage number is inside the box after the update ? I’m using phone 2

JP

JefRoftin yes… it’s only outside when quick settings/notification panel is down

imi-

Copied iOS status bar icons… Turning on/off DND in quick settings now requires extra input since it was replaced with new “Modes” 👎

Styphoryte

Uhm what are these icons and is there a way to change them back Jesus i literally won’t update if my icons are going look like that WTF man. Edit: Well I may be able to update because I can edit my status bar icon theme using Iconify, you have to have Xposed (LSposed) and Root of some sort though to do this.

Edit: Welp Iconify has known LSposed bootloop right now using Android 16 so damn guess I’m waiting awhile yet to update it looks like. Don’t really need “Essentials” anyways not for me but I do hope they can add something to change the system UI icon theme as well as the status bar icons for next update! Then I’ll update for sure eventually…

JP

Styphoryte those are new status bar icons from nos4.0…

except 5g+ icon… fonts are different for that icon only… that icon is managed by service provider…

Update locks every game (system OS shutdown) to 60hz. Just a forewarning, as you will be unable to uncap fps higher than 60hz with the NOS 4.0 update. This is the same as the phone 3a, very unfortunate.

JP

Womey i checked bgmi/pubg and it’s working at max frame rate…and i never saw fps go below 120 in any app…even lockscreen is at 120fps…and i didn’t even enabled always max frame rate from dev options…

MaulanaRifqi

Does the battery percentage in lock screen always show when charging, even when the battery percentage setting is turned off?

KaranSaraswat_H9dKjBtOqw

When I receive a notification it gets stuck at that place and the volume icon also

Womey

JP not working for me for any developer settings on CMF1 and 3a running NOS 4. Must be regional shutdown for international devices. Disabling default framerate does nothing when toggled. Support claimed this is intentional as they rollout NOS 4.0 for applications, disabling the developer option toggle built into the update so it does not work as intended.

flashbang

Ayo WTF!!!!!

So much inconsistency

How tf did they manage to mess this up🫠

The bluetooth tile, damn looking like shit

The media player and other notification aren’t even same size anymore, the media player looks like it is punched from both left and right and compressed into a box and what’s with battery icon, it wasn’t even required to be changed🥲

Extra Dark Reduces brightness and app drawer looks ugly af with extra Dark mode� (compared to extra Dark mode off)

Ps-screenshot doesn’t even capture that

And whyy the media player is way darker that the cover isn’t even clearly visible anymore

JP

Womey ohh .. what games are you referring here… i might give it a try and see if same happens with my device or not…

Womey

JP old school runescape specifically, but any other basic game from playstore stays the same, developer toggle removing 60hz cap does not work as intended. Scrolling the quick access panel indicates 120hz, swiping the quick access up in any app or game jumps immediately back to 60hz indicating what support replied it is an intentional lock to not overheat devices or overload the phone. I am guessing NOS 4 is heavy and to avoid bugs this option is removed for my area (USA) beta devices. This was confirmed with Jagex as well, this is an android system setting that has nothing to do with them or their application as if the toggle is not working indicates a system OS lock from Nothing.

JP try modern warships

JP

2kai i tried it and it’s locked at 60fps…all graphics settings are set to 120 but it never go above 60fps .. but it’s working smooth ith highest quality graphics settings… but its not important for competitive games …
