“I can’t find the Extra Dark Mode shortcut. Maybe it has been changed or removed—why? It was actually a really useful feature.”

Just the Phone and the Update all within two days, I wish there was an option to adjust the PWM rates for sensitive eyes.

Hopefully this could be a feature sometime soon.

ProvatDas

I have face a stuck and hang issue after this update.

Scenario 1: Got a call on my phone but i couldn’t receive it. My phone’s display is off. Pressing power button also didn’t work for couple of times.

Scenario 2: swiped down for notification panel but couldn’t go back for a few seconds.

steveeeg Likewise, I haven’t received it. I’m in France myself.

etidorhpa

josegrind My battery is draining a snails pace.

Anonymous1078

Getting better standby time too. I don’t use my phone all day so it’s nice to charge every 2-3 days

Yeah my battery has been fine on this one. If anything, standby was majorly improved defs agree. I set my phone aside for 2 days and it was still going on standby.

BUDDHAPALKHOBRAGADE

Battery drain issue happening after updating to this.

Battery percentage going out when we scroll down for control panel.

Pls resolve it ASAP. Change control panel it’s look boring and old. Try something new.

Ani_Vri_007

Can anyone just show the new animation that have been added to the recorder app

As this new thing isn’t included in the update of Nothing phone 2a plus

roy-stricko

steveeeg 3a pro here, no update!

TonyAgnew

It’s beginning to look like a lot of 3a/Pro users have not had this update yet. It’s becoming unacceptable when you see CMF and phone 2 users getting it weeks ago
