Do anyone face the same problem same as I do after the recent update? My fingerprint sensor doesn’t detect and scan for a couple of times in my nothing phone 3a pro!

Well it finally happened, I got to experience the worse battery life after this update, that everyone was complaining with theprevious ones. Goddamn nothing, do something.

PatrykKupisz It’s worse that it only affects certain phones, cuz people who get lucky and dont get the random bugs love to call others “crybabies” for whining about issues until it finally hits their phone too. Nothing would be pressured into acknowledging issues better if everyone agreed something is wrong and reported it online

After the latest software update yesterday, my phone has started overheating badly. Even during normal usage, it becomes extremely hot—so much that it’s uncomfortable to hold in hand. This issue was not present before the update.

Please look into this matter urgently and provide a fix as soon as possible, as it is seriously affecting daily usage and device safety.

alright so, as we all know that the nothing os 4.0 update has now been implemented to all the major nothing phones but my issue is that i have the nothing phone 3a pro and after i got the second update of nothing os 4.0 (i am talking about the 2nd 4.0 update not the first 4.0 update), everything feels laggy. the gameplay experience is not smooth like it used to be, camera lens switching became more laggy and overall the whole performance became slow. i hope the nothing team fix this on their next update thank you.

Where did the button go to manually turn on bedtime mode?

Firmware (bot) I am experiencing very high battery drain after this update. Does anyone have the same issue ? also incresed heating too.

josegrind

Lycan_thrope I’m having that problem too. I’ve raised a ticket with logs, so they are currently working on it. Which is good in terms of customer service, I’m happy with the quick response.

I guess it’s a software issue, as there was no problems before the update. So, I hope the fix it as soon as possible.

I don’t get it after every update there is battery draining problem or another problem plz I know you people perform lot of tests before releasing an update but plz fix this battery issue as soon as possible. When I charge my phone to 90 in 20 or 25 minutes of usage it degrades to 80 I am talking about phone 3a

I had the same problem when I tried videoing last night. This morning I’ve changed the screen display to 120Hz and suprisingly no problems with videoing at 4K.

tejasmohadikar98

rcward tried but still not working for me. Even in 4k zoom is not working properly instead of 8x it goes only 6x.

after I updated phone 3a to Asteroids-B4.0-251229-2335-EEA the app drawer appears in English all tho I have my phone set in settings in Czech for example in the drawer Google drive should be named disk

Dimas

klenkys Maybe im not facing the same issue but back then i have my widget bugs after NOS 4.0 Beta. My widgets not updating especially calendar, pedometer and screentime widget. What did i do is clearing cache and storage iof Nothing Launcher in Apps Settings. After performing that my widget is work properly and no issues until now.

Orion_7u-op

Orion_7u-op

abstractethic Are you having problems with the photos you take like sometimes they come good after processing and sometimes not like sometimes my phone takes photos like a very cheap phone no clarity over saturated and contrasty also when I take a photo of text with a telephoto lens they appear more clear in preview as compared to the photos after processing. So are they degrading the camera for the upcoming phones or is it just a temporary issue with this particular update

abstractethic

Orion_7u-op i a, a cmf p2p user i have no such issue
