Thanks for the update.

No mention of App Services being removed. Still (im)patiently waiting for that before upgrading to 4.0…

App Recommendations

With the latest update on Nothing (a) series and CMF phones, you may see a small pop-up suggesting recommended apps. This is part of the setup experience and appears during initial device setup or after certain software updates, when setup-related flows are triggered again. If you’re not interested, you can simply swipe left to dismiss it.

If you prefer not to use this feature at all, you can turn it off at any time by going to Settings > Apps > All apps > Top-right icon >

Show system > App Services > Disable.

We’re also working on adding support to completely uninstall App Services in a future OTA, following the same approach as Meta Services.

sean (1) app services is removable now with this update

YoshiMK yup i agree that is definitely something that needs to be fixed. i usually use my camera to record videos. i don’t use my phone to click photos of people a lot, its much less frequent.

good luck with the pixel man.

verbatimming same here, no solutions if you use the stock camera

the only solution would be to use gcam.

I feel the animation changed after this update when close and opening the apps

Dimas

ZihaoZhang didn’t notice about this, how is the current animation compared to previous version ? is it better ?

insanepotato

Animations look different with less fade transitions this time. Also I noticed a subtle change in the appearance of notifications. However, the notifs still just disappear without any animation when you slide up from the lock screen.

ishantraj3011 restart your device sir. Again it will show you..

Animations are much smoother now, and the camera appears to be better than before. They have also updated the Nothing Diagnostics app (you need to enter this number into the Phone app: *#*#9#*#*), and this is good for testing the functions of your Nothing Phone.

I am also glad that we finally have the latest security update patch from this month (released 2 days ago), as it shows that Nothing is trying to keep up with the updates for their devices now.

Feedback is working again!

Will have to try android auto….

joghorizon

No update for 3a lite? 🙁

ZihaoZhang

Dimas smoother but slower than before.

Funky animation, love it

WalinAhmed

The animations have gotten even smoother, nearly IOS-like and the app opening closing animations are more satisfying.

Yet, the problem of microphone being weak persists. In WhatsApp or in phone calls where loudspeaker mode is turned on, the receiver hardly hears me from a normal mouth distance, I have to place the phone near my mouth while talking in the speaker mode. Even if I turn on ‘Normal’ from the top corner, instead of noise cancellation.

Mohd_Isham

But I did feel like I was setting up vivo or realme… too many apps to uninstall…

Dimas

ZihaoZhang in your opinion which animation is better ? this new one or the previous one ?

YoshiMK

80% to 69% overnight with 1 minute SOT.

I’ve joined the bad battery life gang after great battery life since release. Perhaps a one off… will see

Dimas

YoshiMK haven’t test for overnight case but my phone still have a same battery consumption from the previous update.

JP

YoshiMK try app optimisation and update will anyway take some days to get normal

YoshiMK

Dimas if you’ve not tested it how do you know?

I don’t care either way as moving on from Nothing as the camera shutter/processing lag is horrible

Dimas

YoshiMK i just got an update at 5 am, so far my battery consumption is still the same (from the morning to this evening). Lets see how is my battery drain during this night.

And yeah, shutter speed and lag processing still become aspect where Nothing should improve for Phone 3a series.
