Dear Nothing Support Team,

I am writing to report a significant performance issue with the camera app on my Nothing Phone (3a Pro) after updating to Nothing OS 4.0.

Since the update, the camera experiences severe lag when capturing photos. After tapping the shutter button, the app freezes for a few seconds before the image is taken, which makes normal usage quite frustrating. I have noticed that this issue has also been reported by several other users, suggesting it may be a software-related problem.

I kindly request that this issue be addressed in an upcoming OTA update at the earliest possible convenience. Please let me know if you require any logs, device details, or additional information from my side to assist with troubleshooting.

Thank you for your time and support. I look forward to your response.

Battery is good if you didn’t update from beta to stable.

This was my 3rd full charge since re flashing to 3.2 and updating to 4.0

Srivatsan-N

Anonymous1078 this is actually contradicting to what most users are claiming. Either they’re expecting to improve battery life or some of the apps are not optimised properly. How about the overall UI smoothness? Does it stutter?

When I unselected “Automatic network selection” and I chose specific network, it still changed automaticly.

System: NOTHINGOS 4.0

Function name may differ from original. In polish version, it’s under “Sieć i Internet -> Karty SIM -> Automatyczne wybieranie sieci”
